Here's an interesting tidbit about Purity...

Purity 3.0 includes a load of new and updated features. FlashArray now features always-on data-at-rest 256-bit AES encryption. Additionally, Pure Storage has enhanced its ZeroSnap snapshot feature which speeds up VM cloning. The technology enables a typical VM clone operation to be offloaded to the FlashArray which can clone a single VM in about 2 seconds, or 1,000 VMs in 30 minutes. Pure Storage has also furthered their integration with third-party applications as well by including the OpenStack CINDER driver and by now supporting IBM AIX ACA (native multi-pathing), VMware vSphere VAAI xCopy, and the vSphere Web Client management plugin now supports iSCSI.

Also new, CloudAssist provides problem alerts, identification and analysis in the cloud, and crowdsourced intelligence. CloudAssist support members monitor arrays in real-time and can resolve issues and perform maintenance via a secure connection if the customer requests that. Any problems diagnosed are uploaded to the analysis engine so that all customers can be notified about potential issues.
