An increasingly common use case for Active-Active replication in vSphere environments is vSphere Metro Storage Cluster (vMSC) which I wrote about in this paper recently:
This overviews how a stretched vSphere cluster interacts with the active-active replication we offer on the FlashArray called ActiveCluster. Continue reading Tech Preview: vCenter Site Recovery Manager with ActiveCluster
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:

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
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:

In Purity 5.0 Pure Storage released support for Active/Active replication on the FlashArray. This provides the ability to present the same storage volume simultaneously from two different FlashArrays.
For a good overview, check out this video:

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.

One of the most strategic benefits of Virtual Volumes is how it opens up your data mobility. Because there is no more VMDK encapsulation, VVols are just block volumes with whatever file system your guest OS in the VM puts on it. So a VVol is really just a volume hosting NTFS, or XFS or whatever. So if a target can read that file system, it can use that VVol. It does not have to be a VMware VM.
Let me start out with: YES our VVols deployment will be GA VERY soon. I am sorry (but not really) for continuing to tease VVols here.
This is one of the reasons we do not treat VVols on the FlashArray any differently than any other volume–because they aren’t different! So there is no reason you can’t move the data around. So why block it??
Some possibilities this function opens us:
- Take a RDM and make it a VVol
- Take a VVol and present it to an older VMware environment as a RDM
- Take a VVol and present it, or a copy of it, to a physical server.
- On the FlashArray we are also introducing something called CloudSnap, which will let you take snapshots of volumes (aka VVols) and send them to NFS, or S3 to be brought up as a EBS volume for an EC2 instance.

I have blogged a decent amount recently about VVols and in many of those posts I mention config VVols. When using vSphere Virtual Volumes, VMs have one, some, or all of the following VVols types:
- Data VVols–every virtual disk you add creates a data VVol on your array
- Swap VVol–when you power on a VVol-based VM, a swap VVol is created. When you power it off, this is deleted.
- Memory VVol–When you create a snapshot and store the memory state or when you suspend a VM, this is created.
- Config VVol–represents a folder on a VVol datastore.
This statement about config VVols deserves a bit more attention I think. What does that really mean? Understanding config VVols is important when it comes to recovery etc. So let’s dig into this.
Continue reading What is a Config VVol Anyways?
Quick post. I did some light board videos together on vSphere Virtual Volumes. Lightboard videos are pretty fun to do, the unfortunate part is that I have horrible hand writing. So I immediately apologize for that.
A common question I get with these videos is how do you write backwards. I don’t. I am nowhere near that skilled, as you can see I can barely write forwards. I write normally which appears backwards and the video team mirrors the video.
This is a three part series, the entire playlist can be found here:

I have been talking a lot about Virtual Volumes (VVols) lately with customers and when I describe what they are a frequent response is “oh so basically RDMs then?”. ..
…ugh sorry I just threw up in my mouth a bit…
The answer to that is an unequivocal “no” of course, but the question deserves a thorough response.
So first let’s look at how they are the same, then let’s look at their differences. And not just how they compare to RDMs, but also VMDKs as you traditionally know them.

Virtual Volumes provide a great many benefits, some large, some small. Depending on the VM, recovering a deleted VM could be either of those.
With traditional VMFS, once you have selected “delete from disk” restoring that VM could have been a process. Either restoring from backup or hoping you had a snapshot of the VMFS on the array. Either way, you are probably going to incur data loss, as the last backup or snapshot is unlikely to be from the time right before the deletion.
Let me be VERY clear here. Regardless to the rest of this post, I am not saying once you move to VVols you do not need backup! You absolutely still do. VVols just give you a nice way to do an immediate recovery of the latest point-in-time without having to lose anything, assuming your array support it.
“Wait, did you say delete VM “AD” or VM “80”?”
“Um… definitely not AD that’s our active directory…”
