This, in turn, moved the bottleneck down to the array volume queue depth limit. ESXi was once the bottleneck due to its locking mechanism, then it fixed that with ATS. The main point is that there is always a bottleneck somewhere, and when you fix that bottleneck, it is transferred somewhere in the storage stack. From a FlashArray perspective, there is no immediate performance benefit to using more than one volume for your virtual machines.

A single FlashArray volume can offer the full performance of an entire FlashArray, so provisioning ten volumes instead of one, is not going to empty the HBAs out any faster. This is not the case with the FlashArray.Ī FlashArray volume is not limited by an artificial performance limit or an individual queue. This limited what a single volume could do from a performance perspective as compared to what the array could do in aggregate. The introduction of ATS removed scaling limits via the removal of lock contention thus, moving the bottleneck down to the storage, where many traditional arrays had per-volume I/O queue limits.
