For the FlashArray, this rule consists of making sure devices are using Round Robin and an I/O operations limit of 1.

VMware PowerCLI and Pure Storage

This is a post I plan on just updating on a rolling basis. I have been working on updating the vSphere and Pure Storage Best Practices document and there are few settings that can be tweaked to increase performance. A common question I have and occasionally receive is can this be easily simplified or automated? Of course!
