Editor’s note: This is the sixth post in a blog series by CBT Nuggets trainer Anthony Sequeira that will cover IT storage technology.
If you just decided to enter the world of IT storage, you sure picked a great time. This is because of all of the exciting new technologies that are the rage. This post covers just three main ones.
Virtualization of Storage
More so than ever before, storage vendors are providing a large dose of virtualization technologies in their products. This allows us to have a bunch of physical boxes, with a bunch of physical drives inside, and represent this storage in whatever way we want to end users of our storage. Remember, a main definition of virtualization is any time we abstract the actual physical stuff from the logical representation that users see.
So we might present users with a volume to store their database information. This volume might actually be made up of several different disk drives on several different physical boxes. If you need to expand or shrink the volume for the users, no problem! You can manipulate all you like the physical components that make up the storage and this will allow a transparent manipulation of the volume that they see.
Flash-based storage is revolutionizing the performance we can achieve when it comes to reading and writing data to storage. You might have a pool of flash in front of your mechanical disk drives to speed things up, or you might have an expensive “all flash” solution. By eliminating the moving mechanical parts, flash-based storage features speeds only dreamed of before.
Intense virtualization at many levels of the network has given rise to amazing new cloud computing technologies. Public cloud, private cloud, or hybrid cloud solutions are becoming all the rage, and as you might guess, the latest in storage technologies must be implemented in order to continue the success of these initiatives.
Public cloud technologies refer to accessing data center resources over the public Internet, while private cloud refer to private IP-based networks as transport. Storage-wise, a great example of public cloud would be DropBox. Many companies today rely on both topologies, public and private, when appropriate. This is termed a hybrid-cloud setup.
Until next time, I hope you found this blog post informative, and I’d like to thank you for reading!
