00:00:00 - Welcome to CBT Nuggets' Mastering VMware vSphere
00:00:04 - Version five. I'm Greg Shields.
00:00:07 - Let me guess what's probably going on right now. Maybe you were sitting
00:00:11 - around working with your group policy, maybe swiping out a network
00:00:15 - card, just doing whatever is that involved with the tasks of
00:00:19 - IT. Someone walks up to your desk and slopes down some
00:00:23 - CDs and DVDs for a new piece of software called VMware vSphere.
00:00:27 - And all of a sudden out of nowhere you're being elevated from
00:00:32 - the good old traditional IT world of physical computers and
00:00:36 - servers and desktops and you're being asked to quickly become
00:00:40 - educated become quickly involved in this whole world of virtualization.
00:00:44 - You probably spent some time looking virtualization.
00:00:46 - You're probably familiar with it. You can't read anywhere in the IT
00:00:49 - press these days without coming across an article or two
00:00:53 - on virtualization itself. But really getting down into the click
00:00:57 - by click of how you would design and construct and operate
00:01:02 - and make sure that that whole virtualization environment stays running
00:01:06 - over the extended period of time, now that may not be something
00:01:09 - that necessarily you have a lot of experience with. And so consequently
00:01:13 - you've decided I'm going to go and learn this thing. Well I'm glad you have. As I
00:01:17 - mentioned my name is Greg Shields and I've been working with virtualization since
00:01:20 - its very beginnings. And I have the unique opportunity to once
00:01:24 - again put together a video training series here with CBT Nuggets
00:01:28 - to assist you with mastering this new technology that we think
00:01:31 - of as VMware vSphere. I've put together twenty of these
00:01:35 - different nuggets, where essentially you and I are going to
00:01:38 - spend some time going through that whole design, build and
00:01:43 - operate activity as it relates to vSphere.
00:01:47 - And I hope that over the extended period of time that I can
00:01:49 - spend some time helping you understand how to make good decisions
00:01:55 - whatever you do this in production. And also if you plan on
00:01:58 - taking that VCP examination, how
00:02:02 - to be successful on that VCP examination. In this series
00:02:07 - we're going to spend some time talking about a whole series of topics, right.
00:02:11 - I want you to help.
00:02:12 - First and foremost I want you to understand really why virtualization
00:02:16 - has really, really gone from this amazing cool thing that no
00:02:21 - one really understands to just something that you do.
00:02:25 - Virtualization is rapid dominance at the Datacenter has occurred over
00:02:28 - an extremely fast period of time. It really wasn't that many years
00:02:32 - ago when all of our servers were physical boxes and we were marching
00:02:35 - into the datacenter to make any changes to them. But the
00:02:39 - incorporation and the embrace of virtualization almost universally
00:02:43 - across IT organizations is a testament to just the benefits that it can
00:02:48 - provide to both you as an IT person and also as your businesses,
00:02:53 - some one needing to accomplish something with the benefits
00:02:57 - of computing.
00:02:59 - So this series attempts to kind of solve two things. First
00:03:03 - and foremost it tends to help you understand how to build, configure
00:03:06 - and operate vSphere. By the end of this you're going to hopefully
00:03:09 - understand all of the different, the real vulgarities associated
00:03:13 - with working with vSphere and the buttons you need to click
00:03:16 - and all that sort of click here, click here sort of stuff,
00:03:20 - that's required to put a vCenter environment up in operations.
00:03:26 - Now the second piece of this is also understanding hopefully
00:03:29 - for myself just the things that I've learned over the years
00:03:34 - that I can hopefully in part to you, that are good decisions,
00:03:38 - good ways to implement things. Best practices for implementing
00:03:42 - vSphere, because vSphere there are a lot of moving
00:03:45 - parts. And you can connect those moving parts and a lot of incorrect
00:03:50 - ways and there only a few really correct ways that will ensure
00:03:55 - that you are successful both in the short run as as your environment
00:03:59 - grows over time. So I hope to be able to come to share with
00:04:02 - you what I learned over the years and help you be successful
00:04:05 - there. And then thirdly also is prepping for that all important
00:04:08 - the VCB exam.
00:04:10 - Now the VM certified professional exam is a certification
00:04:15 - exam obviously from VMware, it's a single exam. I would
00:04:19 - highly recommend dropping by VMware.com and picking up the
00:04:23 - VCP5 Exam Blueprint. Now the Exam Bluerprint, an excellent document,
00:04:29 - an excellent piece of work. VMware has done a really good job of outlining
00:04:34 - step by step and task by task all the things that you've
00:04:38 - got to know in order to be able to take that exam. And you
00:04:41 - know if you're not interested in the exam, if taking that
00:04:46 - exam is not something that is going to be useful for you or your
00:04:49 - career don't worry because the focus here is not necessarily
00:04:54 - specifically getting you ready for those questions. The focus here
00:04:58 - is helping understand what virtualization is and how it works
00:05:01 - best with vSphere. But along the way
00:05:06 - you may make mention from time to time where certain elements are
00:05:09 - just good to know because they tend to be noted on the
00:05:14 - exam, they intend to be exam type things. And so if you are intending
00:05:19 - on taking the exam take a look at that the VCP Exam Blueprint
00:05:22 - down there. It's on VMware.com, it's on their education
00:05:25 - certification location where you can learn very specifically
00:05:29 - what you need to know.
00:05:31 - You will find that the items that Blueprint so that the
00:05:36 - breakdown structure of all the knowledge that you need to know,
00:05:40 - I have kind of taken the information from that document.
00:05:45 - Re-factored it into a slightly better story line, but you'll see
00:05:49 - kind of the same actions found here in this training series
00:05:52 - they kind will see inside of the Blueprint and part of that's purposeful,
00:05:56 - because the exam intends to validate that you know what
00:06:01 - you need to know. But in order to get there you've probably
00:06:04 - got to know those things also and so kind of generally aligning
00:06:09 - how you will construct your vSphere environment according to
00:06:12 - that Blueprint. In a lot of ways assists you down solving both
00:06:16 - of those goals.
00:06:18 - Now the first thing I really want to talk about here in and
00:06:21 - we're not actually going to get into the click by click until we
00:06:23 - get to nugget number three. Because before you actually
00:06:27 - even start putting bits into disks, you've got to understand really
00:06:33 - what the role of virtualization is the Datacenter. And also
00:06:35 - what the role of vSphere is amongst everything. And
00:06:40 - they're recognizing Virtualization's Rapid Dominance
00:06:43 - of the Datacenter is an important understanding for in many ways
00:06:47 - justifying your move towards virtualization. I say often
00:06:52 - that virtualization has very, very rapidly gone from a really
00:06:57 - cool thing. There was a time period not that many years ago
00:07:01 - were virtualization was the hottest thing coming and going.
00:07:04 - And in a very short period of time it went from a really exciting
00:07:08 - thing to just kind of something you do. And so today this is,
00:07:13 - I'm filming this somewhere near the end of 2011.
00:07:16 - So in this time period a very large if not almost majority
00:07:22 - of all IT workloads these days are being run inside of a virtual environment.
00:07:28 - IT has subscribed virtualization because virtualization presents
00:07:32 - some very important benefits, such as compression, consolidation,
00:07:36 - efficiency and optimization.
00:07:38 - You know for most environments, for most businesses,
00:07:42 - the number one reason why we move the virtualization is just simply
00:07:45 - because well I have 50 servers and all those servers are
00:07:50 - run at 5% utilization and it's a huge waste of power in
00:07:53 - a huge waste of space. So if I shrewish those 50 servers down
00:07:58 - so I can fit 10 servers on to one server,
00:08:01 - then I just have less stuff that I have to manage in the physical world.
00:08:04 - The less I have to manage means the less the power,
00:08:07 - the less to cool, just less to deal with.
00:08:10 - Now there's a further benefit there to not just the space power
00:08:13 - and cooling reduction bits, but the other bit there is the
00:08:16 - fact that a virtual server is just so much more faster
00:08:20 - to get deployed.
00:08:22 - If I ask you the question today, okay,
00:08:24 - and I am.
00:08:27 - So how long does it take between the time somebody walks into
00:08:31 - your office and says, hey we need a new server. And when that
00:08:36 - server is actually in the rack and producing whatever servers they need.
00:08:41 - So if somebody walks in and says, look we need another sequel server today,
00:08:46 - how long does it take?
00:08:48 - Can you do that in a day?
00:08:51 - Can you do that in five days? Some some people commonly, honestly,
00:08:56 - the most common answer I get out of people when I ask them
00:09:01 - that question is really takes me about a month, right.
00:09:04 - Does it take you a month? I mean if somebody comes in your
00:09:07 - office today and says I need a new server, could it take 30 days to
00:09:11 - get a new server, possibly think about that. Right, you need a
00:09:14 - new server and so you've got to go speck one out and then you've got to go call
00:09:19 - dollar IBM or HP or whoever handles your servers.
00:09:24 - You've got to tell them what you want, they've got to build it, they've
00:09:26 - got to ship it to you. You've got to unbox it, you've got to find space on
00:09:30 - the rack. You've got to put it in the rack and network it and connect it to storage
00:09:33 - and add an operating system. And then put on whatever applications
00:09:37 - are required and there's probably nine levels of process and
00:09:41 - change control that you've got to go through in order to do
00:09:43 - that. So the time difference between a new service
00:09:48 - request and a new service these days is honestly measured in
00:09:52 - a month or more, it's measured in weeks.
00:09:55 - Well when you move to virtualization,
00:09:57 - virtualization says, all right what if I just have a bunch of
00:10:00 - equipment that is available and that creates an amount of
00:10:06 - supply, so a certain supply of resources that I can then apply
00:10:11 - to virtual machines. And I can then rapidly deploy new virtual
00:10:16 - machines when that servers requests comes in.
00:10:20 - I shall find out a little later on with the right technologies in
00:10:23 - place you can create very nice templates and clone a VM
00:10:26 - from a template so you know you have a configuration control
00:10:29 - VM right from the get-go. And if you have enough resource supply,
00:10:33 - if you have enough SPU, memory, network and storage, well you're going
00:10:37 - to be able to provision that virtual machine and you'll have
00:10:40 - that virtual machine up in minutes or hours instead of a month.
00:10:43 - That's great, that's a great thing for management, that's a great
00:10:47 - thing for reducing the drag that IT places on business
00:10:51 - agility. I know those are business-y kinds of topics, but you know
00:10:55 - every time that your business comes to you and they have to
00:10:58 - plan a month ahead a time for those sorts of things, that's not a great
00:11:01 - deal. Also virtualization when you implement the right functions,
00:11:07 - When you implement the right protective measures that
00:11:11 - come with virtualization, you also reduce the risk of a server
00:11:13 - failure. Now depending on what level of protection
00:11:17 - you want to put in place, the server itself might fail.
00:11:21 - VMware HA, if I lose a host, I'm gonna lose that virtual machine, but I'm gonna
00:11:26 - lose it for
00:11:28 - three minutes, five minutes the most before it automatically
00:11:31 - powers on somewhere else.
00:11:34 - When was the last time you were out at a barbecue and it's a Saturday
00:11:37 - afternoon, maybe you've had a beer or two, you know you're
00:11:41 - cooking up steaks and your pager goes off because one of your
00:11:44 - services failed. While how many minutes does it take for you
00:11:47 - to get that server back online and running again.
00:11:50 - You might have to put down the barbecue tongs and get in your car and
00:11:54 - drive to work. And if you living on the other side town well there could
00:11:57 - be traffic.
00:11:59 - So it could take a really long period of time to get that
00:12:01 - server back up and operational again. So just that the sheer
00:12:05 - operational issues associated with server failure and applying
00:12:08 - HA to that or DRS or even full tolerance to that really reduces
00:12:13 - the amount of down time that a server is going to have whenever actual
00:12:17 - downtime occurs. So virtualization in itself really improves
00:12:22 - the availability of services. Also means that you can perhaps
00:12:27 - stay at the barbecue instead of having to drive
00:12:30 - into work.
00:12:32 - It also allows you to optimize the use of those expensive physical
00:12:36 - resources. And I think I mentioned that,
00:12:40 - you know, I don't know the average utilization of a Windows
00:12:44 - server industry wide, I have been told is somewhere like
00:12:48 - 5 to 7% worldwide.
00:12:51 - So you go to any Windows server and 93 to 95%
00:12:55 - of the time, that Windows server is just idly flipping ones and
00:12:59 - zeros back and forth to keep itself busy until it to actually
00:13:01 - do something. And I don't know if you're a manager and you
00:13:05 - have a person, an employee that's only working 7% of the
00:13:09 - time, what are you going to do with that employee. Well you're probably going to either
00:13:12 - give them more work or tell them they need to go find another job.
00:13:15 - But why do we do this with our servers? It's expensive, they're
00:13:18 - very expensive and then running them with power and cooling
00:13:20 - is even more expensive. So squishing together those unused
00:13:24 - processor cycles across many servers allows us to have a more
00:13:28 - optimized use of those expensive physical resources. Virtualization
00:13:31 - in itself means that I'm getting more out of the stuff
00:13:34 - that I paid for and that's great.
00:13:37 - A real big benefit here to is this whole notion of disaster
00:13:40 - recovery and making disaster recovery finally cost effective.
00:13:45 - I have a buddy of mine who was working in a financial services
00:13:50 - organization and this is back in the way old days prior to
00:13:53 - virtualization. And because they were financial services they
00:13:56 - had to have a disaster recovery site because
00:13:59 - it's people's money. And the way that they did a disaster recovery site is when
00:14:02 - he went to build a server then he would go and build another
00:14:06 - server and he would drive the other server over to the other
00:14:09 - Datacenter and if he had to make a change on the first one
00:14:12 - he would have to drive over to the other Datacenter
00:14:14 - and make a change on the second one. Really not cost effective as a disaster
00:14:19 - recovery scenario.
00:14:21 - Now with virtualization however, I have the ability to encapsulate all the configurations
00:14:26 - that is a virtual machine down to just
00:14:30 - one single file.
00:14:33 - A virtual disk is a virtual disk and it's one file large. So
00:14:37 - with that virtual disk in my hands, I can then replicate the
00:14:41 - contents of the virtual disk from one place to another. And
00:14:44 - so it creates this really cost-effective sense of disaster recovery.
00:14:48 - It's not, I don't know,
00:14:52 - it's not hard to do disaster recovery, it's still challenging.
00:14:55 - But all whole driving servers around problem just really isn't there
00:14:58 - anymore. So disaster recovery much much easier in virtualization
00:15:02 - because we've now got the automation functions that
00:15:08 - distill all the way down even to SNB. Even SNB's can do disaster recovery
00:15:12 - these days of virtualization very very very easily.
00:15:16 - And lastly this is really helping you come to grips with this
00:15:20 - impending notion of cloud computing.
00:15:23 - Right now today at the end of 2011, beginning
00:15:25 - of 2012 there are a lot of people still afraid of cloud computing.
00:15:27 - And it's understandable it's a very you know shattering, it's
00:15:32 - a very disruptive technology. A lot of people wondering where it
00:15:36 - fits and whereas virtualization and cloud computing are by
00:15:40 - no means the same thing,
00:15:43 - the embrace of one
00:15:46 - begins to lead one in to the embrace of the other.
00:15:50 - So becoming familiar with vSphere is a good educational
00:15:56 - point for your resume, for your taking the test. For
00:16:01 - just the wisdom that you can apply to your entire, the
00:16:07 - contribution that you provide your company.
00:16:09 - And that's a good thing. You know becoming more valuable to
00:16:13 - your company is really important and so there's no better way
00:16:16 - to do it these days, it seems, than by becoming really really
00:16:19 - familiar with virtualizations and especially advanced virtualization.
00:16:22 - stations, topics.
00:16:25 - Now, before we even get started right, before you actually even
00:16:29 - start watching working with me in these videos and learning
00:16:33 - together with me that there are a couple things you have to
00:16:36 - know and and luckily they're not that that bad.
00:16:40 - A couple of prerequisites for this series number one, is just an
00:16:43 - understanding of the Windows OS. If you've been working
00:16:45 - with the Windows OS for really any period of time, you are
00:16:48 - familiar with it, great.
00:16:50 - Also no fear of Linux.
00:16:54 - Where as in vSphereV4 and 4(1) and particularly
00:16:58 - now in vSphereV5, the number of things that you
00:17:03 - have to do that make you resort back to the old Linux OS
00:17:07 - stuff, the Linux UI, which is coming on line, getting
00:17:12 - less and less. In fact in version five there is ESX anymore,
00:17:17 - there's only ESX1 and ESX1 is a very very very
00:17:20 - very very very stripped down almost appliance like version
00:17:25 - of Linux. Some people don't like it when you call ESXI Linux, but
00:17:29 - it still runs off, it has a management partition there that
00:17:32 - runs off of highly tailored version busy box Linux. You can drill
00:17:36 - into that Linux if you want. You can play around with that Linux, but
00:17:39 - I will tell you that in this series I'm actually going to spend
00:17:42 - almost no time
00:17:45 - in the Linux UI.
00:17:47 - But having no fear of it, having at least some comfort level
00:17:51 - with it will assist. There are some commands that you probably
00:17:56 - should be aware of. If you're going to take the exam, it is
00:18:00 - commonly asked for you to understand what the Linux commands are.
00:18:06 - But just having no fear of the Linux O/S even if you don't have
00:18:09 - experience, it's just no fear is important here. I also ask that
00:18:13 - you have a basic knowledge of virtualization concept and also networking
00:18:17 - storage. It's not necessary, I mean if you
00:18:21 - had extensive knowledge of virtualization, you probably wouldn't be watching
00:18:25 - this series.
00:18:27 - But simply having understanding that virtualization involves
00:18:30 - a hyper-visor and that there virtual machines that sit on
00:18:34 - top of that hyper-visor and they're all sort of atomic and all sort of
00:18:38 - Isolated from each other just a basic knowledge of what virtualization
00:18:41 - is, is important because I don't just jump right in the
00:18:44 - how to use the vSphere right around nugget number three. The same thing with
00:18:48 - networking storage, basic knowledge of how to figure networking.
00:18:52 - There's a couple of advanced networking things you're going to need
00:18:55 - to know, the same thing with storage, that many of those
00:18:58 - you can you ask questions of your network admin or your storage
00:19:03 - admin as it relates. I'll show you what these things are so
00:19:06 - don't worry about them if you're not completely familiar. The hardest
00:19:10 - part honestly when it comes in networking storage,
00:19:13 - is if you're the type of admin that has been working exclusively
00:19:16 - with direct attached storage and when a network person hands
00:19:21 - you a cable and that you just IP a server. When you get to virtualization
00:19:27 - the whole networking and storage conversation gets a little bit
00:19:31 - more complicated because you're creating an infrastructure and
00:19:35 - in many ways it's the same kind of infrastructure that the network
00:19:38 - admins and storage admins have kind of been providing for you for
00:19:41 - a long period of time. So at the conclusion of this I think
00:19:45 - you're going to understand vSphere, you're going to understand virtualization
00:19:48 - better, but you probably also going to understand virtualization a little
00:19:51 - better too, excuse me, networking a little better to.
00:19:55 - The same thing with storage and so there's benefits here to
00:19:58 - taking this,
00:19:59 - to learning here, because you're going to learn quite a few topics,
00:20:03 - I think over these these next twenty videos. You should also
00:20:07 - have a familiarity with VMware Workstation product. So the
00:20:12 - entire infrastructure that I'm building here and going to be working
00:20:17 - with you on, is based off of VMware Workstations. So the
00:20:22 - term that you would google on is nested virtualization.
00:20:26 - And nested virtualization, what it really means is that
00:20:28 - I have a hyper-visor, which in our case is VMware Workstation,
00:20:32 - that's sitting on top of the Windows computer that I'm looking
00:20:34 - at right here. So VMware Workstation provides a hyper-visor
00:20:38 - and then the virtual machine that we create is ESX, ESXI.
00:20:43 - And inside ESXI, once we've created that, we'll put more
00:20:48 - virtual machines.
00:20:50 - So we're nesting, it's like the Russian dolls that they keep
00:20:54 - going in and getting smaller and smaller. This nested virtualization
00:20:58 - is, I am purposely doing it in this way because not a lot
00:21:02 - of people have access to a server with which to install the
00:21:06 - ESXI directly onto. But you can install it inside a Workstation.
00:21:09 - A Workstation you can download a free demo or free VAL version or
00:21:13 - you can buy it. It's not that expensive, it's completely worth
00:21:16 - the money spent on it.
00:21:19 - So be familiar with it. Spend a minute or two just playing around
00:21:22 - with creating a VM or two, because that will assist you with what
00:21:26 - we're doing when we're creating this nested virtualization
00:21:30 - thing. And the most important is desire to learn. You know I say this during
00:21:36 - all of my training is, this is going to be a lot of fun and I highly
00:21:41 - recommend that you follow along. You know create your own environment
00:21:46 - at the same time you're watching me create this environment
00:21:50 - because we learn by doing. And if we can interact
00:21:55 - so you can listen to me,
00:21:57 - I can hopefully answer the questions that you're thinking at
00:21:59 - the time that you're thinking them and also that you can just
00:22:03 - simply do what I'm going over here. This will help you actually
00:22:07 - really cement this knowledge in the your head.
00:22:12 - It's very important.
00:22:13 - Now down here in the bottom in the box is, I have copied and pasted this
00:22:18 - right out of that VCP,
00:22:21 - that VCP guide,
00:22:23 - the VCP Blueprint and I do this specifically because
00:22:27 - this is what VMware suggests as the minimum prerequisites
00:22:32 - for a candidate for VCP examination,
00:22:36 - or VCP certification. You see here a candidate for the certification
00:22:40 - has about six months of experience working with v-Sphere.
00:22:45 - You've been working for v-Sphere for about six months that's around the time
00:22:48 - that the you might want to be begin taking the test. These are typically
00:22:53 - infrastructure personnel, so you're working on foundations.
00:22:56 - People installing, configuring ESXI, hosts, using
00:23:01 - vCenter Server to monitor and manage troubleshooting and administer virtual
00:23:04 - machines. So not a lot of designed stuff there, there is actually
00:23:08 - a design certification over the top of VCP, but this
00:23:12 - is the entry level certification that just validates the ES.
00:23:15 - You have proven that you are competent in managing
00:23:22 - vCenter.
00:23:24 - Further it says that the successful candidate will most likely
00:23:27 - have additional industry- recognized general IT certifications
00:23:30 - or the equivalent experience.
00:23:33 - Having an MCITP can't hurt.
00:23:38 - In some cases having one of the Linux certs can't hurt, having
00:23:42 - a networking cert can't hurt, having a storage cert can't hurt.
00:23:46 - But the VCP is really intended to be an introductory
00:23:52 - level certification.
00:23:55 - It's the first step on the path.
00:23:58 - Now how to get there.
00:24:00 - What's the steps we're going to go through in order to get to this
00:24:04 - nirvana of VMware
00:24:08 - bliss whatever.
00:24:11 - You'll find that and it's funny because everybody knows wants
00:24:14 - to get to working with virtual machines first or it's like
00:24:18 - hey let's start working on that that DRS load balancing
00:24:21 - cluster, that's what I want to see.
00:24:24 - What's interesting is, you're building an infrastructure here.
00:24:29 - And that infrastructure has to be cemented correctly. You've
00:24:33 - got a put the re-bar in before you
00:24:36 - put the concrete in and you've got to put the concrete in before you can
00:24:39 - put in the carpets in the Windows. And so we have to
00:24:42 - start by essentially digging the hole that we're going to put
00:24:45 - the foundation in before we can to the re-bar.
00:24:49 - This is how I've kind of constructed this outline for us.
00:24:55 - We're going to start here with just a couple of intro concepts here.
00:25:00 - This nugget is as you are currently experiencing just
00:25:04 - what the heck is VMware, what the heck is v-Sphere and
00:25:06 - what is the VCP5.
00:25:09 - And then the next one, I'm just to spend just a minute or two, not that
00:25:12 - long helping you understand what the vSphere Architecture
00:25:15 - and Solutions are.
00:25:18 - I find that most people kind of get the architecture after they have
00:25:25 - kind of played with all the pieces first. So this will not be a very
00:25:28 - long nugget, but I just want to give you a feel for what
00:25:32 - VMware is thinking
00:25:33 - when they're creating this vCenter thing.
00:25:38 - We're then going to install cCenter Server and
00:25:41 - then ESXI. So ESXI is the hyper-visor, okay. That's
00:25:45 - the thing that does the virtualizing. You're going to put ESXI on one
00:25:49 - or more hopefully more physical hosts in your Datacenter.
00:25:55 - The more hosts you put it on the more VMs you can manage
00:25:58 - and then one of those VMs will be a VM running Windows that
00:26:02 - runs vCenter server,
00:26:05 - simple enough. Now the server is kind of its essentially that
00:26:09 - the management tool, it's the management platform that enables
00:26:12 - you to interact with your hyper-visors, your ESXI hosts and then
00:26:17 - also all the VMs that you're running.
00:26:21 - You can connect vCenter server directly into a single ESXI
00:26:25 - box, so you can connect it to a set of them which is the preferred
00:26:29 - configurations. You can operate all of them as a unified infrastructure
00:26:34 - and that's how we're going to do it.
00:26:37 - Today, even though you can't plug it directly into an ESXI box,
00:26:42 - these days people just want to run three or four, six
00:26:46 - or 32 ESXI hosts in one big cluster and allow
00:26:51 - themselves to abstract the resources of those machines for
00:26:56 - use by virtual machines.
00:27:00 - Once we've built the operating system and once we got
00:27:03 - a Windows box running vCenter server and once we've got a couple hyper-visors
00:27:06 - up and running, we're going to start working on the network
00:27:08 - stuff, the storage stuff and the data stored stuff. So
00:27:11 - we've got to get the networking up so that we can get the storage up. And then
00:27:15 - we've got to get the storage up in order get the data storage up. And I'm
00:27:18 - gonna focus on ethernet based storage pretty strongly
00:27:22 - here just simply because our industry is moving very much
00:27:26 - so towards ethernet based storage whether that be fiber channel over ethernet.
00:27:31 - It's just the industry seems to be moving in that direction and
00:27:34 - also because
00:27:36 - if you are a fiber channel shop and you have a real fiber channels HBAs in
00:27:40 - the back of your hosts, of which there are still very many of you,
00:27:44 - for the most part those,
00:27:50 - that configuration, the majority of the work is done
00:27:55 - by the storage admin and you just sort of receive one or more
00:27:59 - lines. You light the thing up and all of a sudden poof lines appear. So there's
00:28:03 - not much to do comparatively from the ESX side or the vCentre
00:28:07 - side as it relates to storage in
00:28:11 - a pure fibre channel shop. Now ethernet based storage fibre channel
00:28:15 - or ISACZI you've got a little bit more work to do. You've got
00:28:19 - to do some IP addressing in certain circumstances. And you've gotta do some fail
00:28:22 - over stuff in certain circumstances. So that's why we're going to
00:28:25 - spend most of the focus on that with the switches and storage
00:28:28 - and ultimately the data stores.
00:28:31 - Then and only then at nugget number eight can we actually start
00:28:36 - working with virtual machines.
00:28:38 - And so we're going to work with virtual machines, we're going to create them. We're
00:28:42 - going to administer and migrate them. This is the vMotion topic
00:28:45 - and then we're going to get to the very very cool topic of
00:28:48 - VMware clusters. This is, you are both welcome and I'm sorry the
00:28:52 - longest of the videos in the series because VMware clusters are
00:28:55 - both just really awesomely cool and also there's just a lot
00:29:00 - there that you now. So that one is one that you may want to
00:29:04 - watch a few times because there's a lot of content in there
00:29:07 - and it's really really really important.
00:29:11 - We didn't go through rapid deployment with cloning templates and then
00:29:15 - from here down we're going to go to some of the individual
00:29:17 - topics that are absolutely required for running your environment,
00:29:22 - but the build of your environment starts here and goes to about
00:29:25 - right here at number 11 and then at this point these are kind
00:29:28 - of branching from there. You have to do
00:29:31 - backup and restore. You probably should update your hosts and profile
00:29:34 - them. You probably will want to move to distribute the switches at some time.
00:29:37 - You probably are going to want to implement security. So all of these
00:29:40 - are the additional topics all the way down to the bottom, which sort
00:29:44 - of conclude the sum body of knowledge that's necessary
00:29:48 - for you to be successful with vCenter. Now if you are planning
00:29:53 - on taking the exam. As I said before you probably are going to
00:29:59 - want to follow along.
00:30:01 - So we're going to be creating a network somewhat similar to
00:30:04 - this. We will have one domain controller dc.company.pri.
00:30:09 - We will have one vCenter server that is actually running
00:30:12 - as a virtual machine called vc.company.pri.
00:30:17 - And we will have two and then at some point later on three
00:30:22 - ESX hosts, ESX1, ESX2 and later on number three.
00:30:27 - All of the hosts have local storage and all of the hosts will
00:30:31 - ultimately connected into a single instance of shared storage
00:30:35 - as well.
00:30:37 - So what should you have if you had a desktop computer with about
00:30:42 - eight gigs of ram and at least two processors, if not more,
00:30:46 - probably four would be even better.
00:30:49 - You will probably be able to support all the needs for this
00:30:53 - if you want to demo this. But this is what we're going to
00:30:55 - be creating. I would also recommend going to VMware's website
00:30:59 - and downloading
00:31:03 - whatever bits are necessary. I think you get like 60 day
00:31:05 - time bomb on all the bits. Just to give you a view of what we're
00:31:09 - going to look at this is the server that we will be playing with.
00:31:13 - This is vc.company.pri. Currently we have,
00:31:19 - looks like three hosts, six processors, one cluster, seven data
00:31:23 - stores, six virtual machines and templates that are created.
00:31:27 - Here's all the stuff over here on the right. It's going to be
00:31:30 - a lot of fun. You're going to get a chance to see all kinds of stuff
00:31:33 - here and interact with vCenter and all sorts of ways that
00:31:37 - will just be impressive and will prepare you just for doing
00:31:42 - this and operations. If you do plan on taking the exam though, there are a couple of
00:31:47 - ideas here about the exam, a couple of thoughts. As I mentioned this is
00:31:50 - the first level exam in the certification portfolio. So this is
00:31:54 - step one.
00:31:56 - Then from there is two advance level certifications, the
00:32:01 - VCAP-DCA and VCAP-DCT
00:32:06 - or oops that's a typo that should be DCD.
00:32:09 - The VCAP-DCA is kind of the second level certification there for administrators,
00:32:15 - for administration. Where as the DCD is for design.
00:32:21 - So if you're interested in creating Datacenters, virtual Datacenters,
00:32:26 - then the DCD makes more sense if you're interested in operating
00:32:29 - them DCA. And then the design expert VC design, VCDX
00:32:33 - acts here is the expert level certification. Not a lot of VDXs
00:32:37 - in the world, but there are few. There also a few desktop
00:32:40 - virtualization to. Certifications these are if you're, if it's
00:32:46 - not server virtualization that you're so much interested in, but desktop
00:32:49 - virtualization these are the expert level certifications
00:32:52 - for that. A few exam stats here. It is a single test to
00:32:58 - pass the VCP. Eighty-five question, 90 minutes if you
00:33:02 - are not an English as a primary language.
00:33:05 - If English is not your secondary language you get 30 more minutes in certain countries.
00:33:08 - Multiple choice, there some exhibits. It is a scaled scoring
00:33:12 - method somewhere between 100 to 500,
00:33:14 - 300 to pass, okay.
00:33:16 - Standard certification tests, \you go to one of those certification
00:33:21 - testing facilities. You sit down you take the test, 90 minutes later
00:33:25 - you know if you passed or not.
00:33:27 - One interesting thing and this is kind of gotcha with the
00:33:31 - VCP, is that VMware still today, whether you agree with that
00:33:36 - or not requires you to take a VMware official course.
00:33:41 - One of the two prior to taking the exam. It can be the
00:33:44 - VMware v-Sphere install figure manage or the VMware v-Sphere what's
00:33:48 - new exam in certain circumstances. But you have to take that
00:33:52 - course and give them money in order to
00:33:57 - be given the certification. Even if you pass the exam you still
00:34:00 - have to go back and take the course or they will not give
00:34:03 - you the certification.
00:34:05 - I leave that for whether you believe that's a good idea or not.
00:34:09 - The VCP-510 hosted by Pearson is actually the exam
00:34:14 - name and number.
00:34:16 - So this series will assist you with all the steps needed to
00:34:21 - be successful with virtualization. It will attempt to also
00:34:25 - prepare you for the exam. Again, there is that course requirement.
00:34:30 - But mostly really I am looking forward to another 19
00:34:35 - of these little nuggets, which will assist you with this whole process
00:34:40 - of elivating your knowledge set to today's most modern
00:34:44 - virtualization platform in VMware v-Sphere.
00:34:48 - But more than anything, really the goal of this at least for me,
00:34:54 - is to help you
00:34:57 - develop your knowledge set, to expand your knowledge set to
00:35:00 - include one of the world's most mature platforms in
00:35:06 - VMware vSphere version five. This is almost brand new technology,
00:35:09 - but at the same time it's five
00:35:13 - revs in, so where we're talking about a technology that at this point
00:35:17 - really it kind of getting fairly mature and this stuff is bomb
00:35:20 - proof. And I've argued many times before that some times it's
00:35:24 - the weakest link in the ethernet environment is the administrator
00:35:27 - who doesn't know that they're not supposed to click that button.
00:35:30 - So don't be that administrator.
00:35:32 - I look forward to spending the next twenty nuggets with
00:35:35 - you. Helping you become more educated. Helping you become
00:35:41 - that much wiser and administrator as it relates to the
00:35:44 - VMware vSphere5.
00:35:46 - I hope this has been informative for you and I'd like to thank you for viewing.
