Is the all-flash data centre just a tantalising dream?


A mixed bag

"taking disk drive arrays out doesn't save a square millimetre of space; it is still there, just empty, and the air in the data centre still needs conditioning"

It may need conditioning, but that few square inches (feet or metres depending on your footprint) will not need *cooling*. And of course, taking the array away means a reduction in power which, if your racks are metered, can lead to a tangible saving.

The article headline is nonsense, but the body of it does talk sense - I expect DCs to be a mixture of SSD and spinning rust until such time as SSD costs come down. We'll see a gradual progression to SSD but also, possibly, less big SAN footprints, as the direct access to large storage volumes does away with the fibre requirement.
