Storage vendors that don’t look like storage vendors any more

Comment Yesterday I was at the Solidfire Analyst day and this idea about the cloud-enabling vendor popped up just after a couple of hours of presentations and demos.

Vendor: Do we need Quality of Service with shared storage arrays?

The Storage Architect I recently had a discussion with a vendor (who shall remain nameless) as to whether we really needed Quality of Service (QoS) in shared storage arrays. His thinking went as follows: if we have a storage array and network with sufficient bandwidth/IOPS, then why bother implementing QoS? At first this seems like a reasonable …
