One of the few hard requirements we make to configure best practices on ESXi for the FlashArray is to create a SATP rule. A SATP rule simply describes a certain configuration (mainly around multipathing) for a specific set of devices (usually devices from an array). For the FlashArray, this rule consists of making sure devices are using Round Robin and an I/O operations limit of 1.

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! And PowerCLI is the best option in most cases–I will continue to add to this post or update it as I find newer or better ways of doing things.
