Some interesting information came out of our research. For example, when users move to a virtual server world, 60% will begin with networked storage vs. DAS; 18 months later that percentage jumps to 74%. Why? Because the mobility of VMs is a primary driver to move to the virtual world--having the storage externally networked is the only way to take advantage of that. Seventy-one percent of those folks will buy new storage systems, and most (56%) will buy more storage than they started with.
Server and desktop virtualization will have a major impact on storage and storage networking. As the server side of the data center becomes more virtualized, the storage side will be required to follow suit. Additionally, this will drive the re-invention of how we manage, protect, store and access information.
Imagine a fully virtualized data center that isn't tethered to the physical infrastructure, but rather floats above, drawing resources as needed. Need more CPU or capacity? Add it to the pool. In a highly virtualized data center where physical locality is unimportant, these resources can be anywhere because it's all logically at your fingertips. Sounds too good to be true? On the server side, it's happening. But the storage and data management side still has a big mountain to climb. Rest assured that this is where it's going and, step by step, it will soon be more than just a vision.
