Using CLI and REST API to perform a FlashArray Protection Group Recovery

In Purity 4.6 a new CLI and REST API function has been released called protection group recovery. This feature allows you to take a protection group that has replicated snapshots and quickly provision its data to a host or cluster for DR or test/dev purposes or whatever.

A continuation of my 4.6 overview post.

Introducing FlashArray Purity Release 4.6

It has been awhile since I have done a solely Purity operating environment post and with the recent release of our Purity 4.6 operating environment I thought it was a good opportunity to do one. I will overview some new features and changes, some big some small.

4.6 has been in Directed Availability (DA) for some time, so many of you might already have this, but I decided to wait until it was closer to GA (this is imminent) to post. Not a gigantic release, but I think there is some cool stuff in it regardless.

Here is a brief listing of some of the new stuff:

NEW FEATURES

  • VLAN tagging Introduces support for VLAN tagging for iSCSI connections to the FlashArray. VLAN tagging allows multiple VLAN interfaces to be configured on physical iSCSI ports.
  • Replication network bandwidth throttling Introduces the ability to set a maximum network bandwidth utilization for replication between two connected arrays. Allows configuration of a default maximum bandwidth and/or a time window during which a different maximum bandwidth is enforced.
  • Deduplication-preserving replication Introduces the ability for Purity to preserve inline deduplication savings when transferring replication data to a target array, to reduce the network bandwidth utilization.
  • Protection group copy Introduces the ability to copy protection groups, including their member hosts, volumes, and snapshots. Protection group copy is supported in the CLI and REST API.
  • The Pure Storage SMI-S Provider Release 1.0.0 of the Pure Storage SMI-S provider is embedded in Purity 4.6.0 release. SMI-S enables both hardware and software interoperability between different vendors’ enterprise storage products and allows vendors to develop to a single standard interface. For more information, please see the SMIS-S release notes.
  • Improved readability of graphs in the Purity GUI In the GUI Dashboard and Analysis tabs, changes the color of the write graph to orange to distinguish it from the blue read graph.
  • CLI Changes This is mostly to cover the new features above
  • REST API version 1.5 Some new REST calls for new features and general enhancements and fixes for our REST API service.

vRealize Automation and the FlashArray

I want to say this is the culmination of my last almost two years of creating vRealize integration for Pure Storage, but that isn’t the right word. It is a milestone, because there is still so much more cool stuff to be done. Especially with vRealize Automation. In many ways it is just the beginning! But I can now demonstrate Pure Storage FlashArray integration with the whole vRealize stack: Log Insight, Operations, Orchestrator and Automation.

Log Insight has a Content Pack. Operations has the Management Pack. Orchestrator has the Workflow Package. Automation also uses that Workflow Package. Let’s talk about how.

Recent ESXi 6 Storage Bugs and the FlashArray

As you might be aware, there have been a few storage-related issues with ESXi 6.0 as of late:

Accidental PDL during dropped paths:

Storage PDL responses may not trigger path failover in vSphere 6.0 (2144657)

Host issues during smartd inquiries:

Issuing a 0x85 SCSI Command from a VMware ESXi 6.0 host results in a PDL error (2133286)

The question that comes up for the Pure Storage FlashArray is are we susceptible? The short answer is no. Let’s explain why. Continue reading Recent ESXi 6 Storage Bugs and the FlashArray
