Stop counting megabytes; it's all about application-aware storage now
This article is part of the Storage magazine issue of January 2014 Vol. 12 No. 11
Whether clay pots, wooden barrels or storage arrays, vendors have always touted how much their wares can reliably store. And invariably, the bigger the vessel, the more impressive and costly it is, both to acquire and manage. The preoccupation with size as a measure of success implies that we should judge and compare offerings on sheer volume. But today, the relationship between physical storage media capacity and the effective value of the data "services" it delivers has become much more virtual and cloudy. No longer does a megabyte of effective storage mean a megabyte of real storage. Most array vendors now incorporate capacity-optimizing features such as thin provisioning, compression and data deduplication. But now it looks like those vendors might just be selling you megabytes of data that aren't really there. I agree that it's the effective storage and resulting cost efficiency that counts, not what goes on under the hood or whether the actual on-media bits are virtual, compacted or shared.
