PowerCLI and VVols Part I: Assigning a SPBM Policy

There are a variety of ways to assign and set a SPBM Policy to a VM. I recently put out a workflow package for vRO to everything VVols and Pure:

vRealize Orchestrator VVol Workflow Package

I also specifically blogged about assigning a policy to a VM with vRO:

VVol VMUG Webinar Q&A Follow Up

I recently did a VMUG webcast on VVols and there were a ton of questions and unfortunately I ran out of time and could not answer a lot of them. I felt bad about that, so I decided to follow up. I was going to send out emails to the people who asked, but figured it was simpler and more useful to others to just put them all here.

See the VMUG VVol webinar here:

You can get my slides here.

Questions:

Would VVols replace the requirements for RDM’s?

Answer:  Maybe. It depends on why you are using RDMs. If it is simply to allow sharing or overwriting between physical and virtual. VVols will replace RDMs. If it is to make it easier to restore from array snapshots, VVols will replace them. If it is for Microsoft Failover Clustering, VVols are not supported with that yet. You still need RDMs. Though VMware is supposed to be adding support for this in the next release. See this post for more info. Continue reading VVol VMUG Webinar Q&A Follow Up

Required vCenter Permissions for Registering a VVol VASA Provider

I’ve had a few customers ask me what are the minimum vCenter permissions required to register a VVol VASA provider. The use case is, I want my storage admin to be able to do it, but I don’t want them to do anything else.

While this can be done in a very slick way with vRealize Automation (more on that in a later post), this can be done with standard vCenter permissions too. Continue reading Required vCenter Permissions for Registering a VVol VASA Provider

vRealize Orchestrator VVol Workflow Package

Ok finally! I had this finished awhile ago, but I wrote it using our version 2.0 plugin–so I couldn’t post it until the plugin was certified by VMware. That plugin version is now certified and posted on the VMware Solution Exchange (see my post here).

Moving forward, we will likely be posting new workflows in various packages (working on an ActiveCluster one now), instead of including them directly in our plugin. This will make it easier to update them and add to them, without also having to generate an entire new plugin version.

So first, download and install the v2 FlashArray plugin for vRO and then install my workflow package for VVol on the VMware Solutions Exchange:

VMware Capacity Reporting Part V: VVols and UNMAP

Storage capacity reporting seems like a pretty straight forward topic. How much storage am I using? But when you introduce the concept of multiple levels of thin provisioning AND data reduction into it, all usage is not equal (does it compress well? does it dedupe well? is it zeroes?).

This multi-part series will break it down in the following sections:

  1. VMFS and thin virtual disks
  2. VMFS and thick virtual disks
  3. Thoughts on VMFS Capacity Reporting
  4. VVols and capacity reporting
  5. VVols and UNMAP

Let’s talk about the ins and outs of these in detail, then of course finish it up with why VVols makes this so much better.

NOTE: Examples in this are given from a FlashArray perspective. So mileage may vary depending on the type of array you have. The VMFS and above layer though are the same for all. This is the benefit of VMFS–it abstracts the physical layer. This is also the downside, as I will describe in these posts.

vSpeaking Podcast Appearance: VVols

A few week ago I had the chance to stop by VMware HQ and catch up with some good friends at VMware. The highlight of the visit was doing an episode of the vSpeaking Podcast alongside VMware VVol engineering manager Patrick Dirks hosted by Pete Flecha and John Nicholson.

Honored to be on the podcast for the third time, thanks again for having me on Pete and John!

Topic? VVols of course!

Assigning a VVol VM Storage Policy with vRO

Amidst writing a vMSC guide for our newly-introduced Active-Active replication called ActiveCluster, I have been taking some breaks to finish my vRealize Orchestrator Workflow Package for Virtual Volumes. I posted a starter post recently:

I am almost done with v1, but until then another starter post. Continue reading Assigning a VVol VM Storage Policy with vRO

Announcing Pure Storage FlashArray VVol GA

This is a blog post I have been waiting to write for a long time. We at Pure Storage are pleased to announce that vSphere Virtual Volume support on the FlashArray is officially GA!

The FlashArray now supports running VVols in Purity 5.0.0 and later. The cool thing about the FlashArray is the flexibility of the Purity Operating Environment–so VVols are supported on all FA 400 models (405, 420, and 450), //M models (m10, m20, m50, m70) and FlashArray//X.

Getting Started with vRealize Orchestrator and VVols

Over the past few weeks, I have been working on writing a vRealize Orchestrator workflow package for Virtual Volumes and the FlashArray. While that is not quite ready to go out, I think some basics for starting to use vRO and VVols are worth noting.

There are three main parts of using VVols with vRO:

  1. Core vCenter SDK–this is what you use to create VMs, datastores, etc.
  2. SMS–this is the service that manages storage providers (VASA) and replication for VVols.
  3. PBM–this is the service that you use for storage policy based features.
