Dedupe considerations for protecting virtual servers
This article is part of the Vol. 11 Num. 8 October 2012 issue of Storage magazine
As more and more servers are virtualized in data centers, deduplication needs to play a bigger role in protecting their data. "Improving data backup and recovery” and “Increased use of server virtualization” tied for the top priority in an IT spending survey conducted by Enterprise Strategy Group in 2012. While server virtualization regularly occupies the top spot, it’s interesting to see backup listed there, but not surprising. As server virtualization adoption continues, users are discovering that while it solves many problems, backup isn’t one of them. VM sprawl and backup I/O It’s arguably too easy to create new virtual machines (VMs), often resulting in “VM sprawl” and a seemingly unending stream of new virtual hard disk files. With only a few mouse clicks, a new VM is created and large chunks of storage are consumed. Historically, backup was one of the most I/O-intensive operations for a server, but because physical servers were usually underutilized, they had I/O, memory and compute resources to spare.

Although it’s become a staple of backup systems, data reduction is still just beginning to appear in primary storage systems. Here’s how it works and who’s doing it.
You can take a lot of the drudgery out of disaster recovery by using virtualization technologies for your company’s servers, storage and desktops.
A new category of storage software is emerging with apps that optimize solid-state storage to help increase I/O performance and fully realize the benefits of flash-based storage.

Keeping up with solid-state storage requires some technical know-how, but sometimes flash vendors make the technology harder for users to understand.
Do we really need data scientists to parse our way through all that big data, or will programmers and engineers and admins handle things OK?
As more and more servers are virtualized in data centers, deduplication needs to play a bigger role in protecting their data.
Convergence -- the bundling of storage, compute, network and virtualization -- is already evolving with new products that redefine ease of use.
