Combining Storage Virtualization and ILM

Arthur Cole

A couple of key questions surfaced this week regarding storage virtualization and its ability to adequately track and monitor data being shuttled between a growing multitude of sources and destinations.


One writer from McDATA was quick to point out that seemingly new technologies like virtualization and information lifecycle management are the modern equivalents of device emulation and heirarchical storage management of 20 years ago. The point: No one technology could singlehandedly solve all your storage woes back then, so it would be naive to think that a single technology like virtualization could do so today.


If your main problem is the legacy silos that have crept up around your enterprise, it will take a robust mix of virtual storage, ILM and intelligent networking to produce a unified storage environment.


Of course, that raises another interesting question: What is the best way to integrate ILM systems into a virtual environment? Any decisions regarding tiered storage are most logically to be made upstream of the virtual engine in some sort of data directory engine. But that means each layer of ILM has to be virtualized, and it all has to be tightly integrated with the virtual engine. Possible, yes, but a complicated scenario.
