Re: Tegile and Nimble aren't "really" AFAs: they were hybrids like Infinidat until recently

Infinidat isn't tiered storage. That's the big difference. The problem is the terminology. Everything which has flash and HDDs in the same box is "hybrid", no matter how it uses those resources.

Tiered storage is on its way out, mainly because there are essentially only two tiers now: flash and large capacity drives. It's inefficient because you have to keep moving data around and applications aren't kind enough to put all the hot data at one end of the volume and the cold data at the other end.

The future viability is dependent on whether the cost of flash will come down enough to make it viable for storing cold data. That's a long way off which is why the big vendors offer multi-product solutions, or tiered storage.
