This post I will talk about using PowerCLI to run a test failover for VVol-based virtual machines. One of the many nice things about VVols is that in the VASA 3.0 API this process is largely automated for you. The SRM-like workflow of a test failover is included–so the amount of storage-related PowerShell you have to manually write is fairly minimal.

One of the fundamental features of the operating environment running on the FlashArray™ is the fact that the same software can run on many different hardware implementation of the FlashArray. This is one of the reasons that we can offer hardware Non-Disruptive Upgrades or when we introduce new features (even things as expansive as VVols) we can support it on older hardware. We support VVols going back to the FA 420-an array that was introduced before I joined Pure Storage® 4.5 years ago.
Furthermore, we have been having increasing conversations around the public cloud. Not just running applications in it, but moving data to and from it. DRaaS (Disaster Recovery as a Service) is an increasingly talked about use case. VMware Cloud in AWS is getting more and more attention at VMworld, and in general. We, at Pure get it. Will everything go to public cloud? No. Certainly not. Will everything stay on-premises? Also, of course not. Some customers will. Some will not at all. Many (most?) will use both in some capacity. So enabling data mobility is important.

It is that time of year again! Top vBlog voting! I would like to thank everyone who voted for me last year–I was absolutely humbled by all of the votes I received–so thank you.
Of course thanks to Eric Siebert at vsphere-land.com for running this year after year–this voting process is no simple task. To vote go here:

I have released a new version of the VMware/Pure PowerShell module which can be automatically installed from the PowerShell Gallery.
Pure Storage PowerShell VMware Module
Updates in this release are focused on VVols. Creating VVol snapshots, copying them, creating new disks from them, retrieving them etc.
I wrote a blog post below on using some of the new cmdlets:

Another post in my series on VVols and PowerCLI, for previous posts see these:
This post will be about managing one-off snapshots with VVols on the FlashArray with PowerCLI.
One of the still semi-valid reasons I have seen DBAs say “I dont want to virtualize because…” Is that they have simple snapshot/recovery scripts for their physical server that allows them to quickly restore DBs from snapshots. Doing this on VMFS requires A LOT of coordination with the VMware layer.
So they tell the VMware team–“okay I will virtualize but I want RDMs”. Well the VMware team says “well we’d rather die”
…and around in circles we go…
VVols provides the ability to provide this benefit (easy snapshot stuff) but still get the benefits of VMware stuff (vMotion, Storage vMotion, cloning, etc) without the downside of RDMs.
So let’s walk though that process.

Yesterday, I wrote a post introducing the new latency-based round robin multipathing policy in ESXi 6.7 Update 1. You can check that out here:
Latency Round Robin PSP in ESXi 6.7 Update 1
In normal scenarios, you may not see much of a performance difference between the standard IOPS switching-based policy and the latency one. So don’t necessarily expect that switching policies will change anything. But then again, multipathing primarily exists not for healthy states, but instead exists to protect during times of poor health. Continue reading Latency-based PSP in ESXi 6.7 Update 1: A test drive
This is my first (but certainly not last post) on the new path selection policy option in vSphere 6.7 Update 1. In reality, this option was introduced in the initial release of 6.7, but it was not officially supported until update 1.
So what is it? Well first off, see the official words from my colleague Jason Massae at VMware here:
Why was this PSP option introduced? Well the most common path selection policy is the NMP Round Robin. This is VMware’s built-in path selection policy for arrays that offer multiple paths. Round Robin was a great way to leverage the full performance of your array by actively using all of the paths simultaneously. Well…almost simultaneously.

In a previous post, I walked through setting up the “off-array” Pure1 VM Analytics Collector. I did skip over some steps that some might prefer I didnt. So here is a more detailed walkthrough of the process.
- Creating an Ubuntu VM
- Install Docker CE
- Create a collector in Pure1
- Install the collector

A few months back I was reviewing our VMware training for our field (and after some direct feedback) realized it wasn’t really doing what our field needed. It was too nuts and bolts technical–which isn’t really what was needed by the masses. There was more of a desire to understand the value of the VMware product, the value of the integration and the value that we as Pure can bring to it.
The ones that wanted/needed more technical training could get that as needed.
In short, what they wanted to be able to do was have the “I’m staffing a booth at a conference and someone asks me about vRealize Orchestrator”. Not being an expert in the product, how to do I quickly understand the value, so I know if I am chasing the right product/solution and I should inquire further.
There are so many options out there, the “why” sometimes can be the most important question. Continue reading VMware & Pure Integration Training Videos
If you are Pure Storage customer and you recently logged into Pure1 (which is our cloud-based management/analytics/support portal), you might have noticed a notification the first time you logged in this week:
What is this? Well this is the great thing about Pure1–we just add features all of the time and this is an exciting one. Two years or so ago I wrote this blog post:
