By now, everyone in the IT Industry is convinced about the benefits of virtualization. Server virtualization – Yes! But storage virtualization? That’s not an easy one!
In Server virtualization, we simply divide one physical server into several virtual environments that saves you lots of money and helps wring the best out of your infrastructures, but did you know that an inadequate storage system can actually cause the economic benefits of server virtualization to fall through because virtual machines can consume large amount of storage?
So, why is it that Storage Virtualization still isn’t as popular as Server Virtualization?
In storage virtualization, we group physical storage from multiple network storage devices so that they look like a single storage device that can be managed from a single console. This can raise several complexities when –
- Data center has storage products from different vendors
- Some vendors provide storage virtualization for their own hardware only
- You need availability of virtualized storage features from vendors in non-virtualized offerings
Throw in the further dilemma of choosing where to put your virtualization: hosts? network? or arrays? Or perhaps being bound by vendor lock-in clause?You probably have been buying additional devices and systems on an ad hoc basis to meet new storage demands, but think of the advantages you could gain with a storage architecture (read storage virtualization) that allows you to upgrade when needed and in a cost effective manner! Now that’s enough to convince you on the virtues of storage virtualization……
Let’s find out why IBM’s VSC is the best bet in the market.
A recent ITG report compared IBM VSC solution to other large vendor (EMC, VMware) over a period of 5 years to determine savings,
And the verdict is – IBM Virtual Storage Center (VSC):
- The only solution to address large-scale multivendor virtualization
- Averaged 72 percent less than EMC for overall costs of ownership
- Averaged 35 percent less than VMware over 5-year total cost of ownership
Supports more than 200 platforms -- all of the major vendors -- as well as from many smaller vendors.
You can get behind the calculations and analysis done in the two ITG reports to understand the how and why of it. As one user shared when asked to describe VSC in simple terms, “It works.”
