PernixData just announced a new release of its core FVP server-side-storage management product as well as a number of product extensions. Of course, you can get all the specific details from its press release but it did make me consider how a company like PernixData is truly a manifestation of a significant change in the storage world. It represents that change by talking a lot about “decoupling” storage performance and capacity. While that’s technically true, what companies like PernixData really reflect is something bigger than that.
For years “storage” has been just that – a singular, monolithic, and only-somewhat-malleable entity. You get more or less of it, and it is more or less capable to deliver some level of performance. The original IBM term of “DASD” – Direct Access Storage Device (how quaint that sounds in today’s mobile and networked world eh!?) – gave way to “disks” and indeed in many parts of the IT world the terms “disk” and “storage” were actually synonymous….despite the existence of alternatives. But, anyhow, for decades we muddled along with what we had. It was the least-worst option in many respects – and this is said with no lack of respect for the brilliant engineering that drove HDDs from MBs to GBs to TBs. It has been quite a ride.
