Competing with the cloud: Achieving high efficiency
A post in the occasional Competing with the Cloud series intended for enterprise IT. In the last post StorageMojo discussed HP's POD systems, which have a PUE (Power Use Efficiency) as low as 1.1, competitive with Google and Amazon. But what about your existing data...
Competing with the cloud: PUE
A post in the occasional Competing with the Cloud series intended for enterprise IT. Ten years ago few datacenter managers considered PUE - Power Usage Effectiveness - the ratio of total facility power divided by IT equipment power - as a competitive advantage....
Flash risks, rewards and “usable capacity”
The cost of flash versus even 15k FC drives has made it common practice to compare "usable gigabytes" to disk array capacity. Pure Storageand, lately, HP, have invoked the idea that, with proper techniques, usable flash capacity can be competitive with the...
Dear StorageMojo: replace 4PiB of tape with object storage?
