This is the start of many blog posts around the recent Purity 5.0 release. I figured I would start with one that doesn’t require an upgrade of Purity to even get! Alongside Purity 5.0, we released the 3.0 version of theFlashArray plugin for the vSphere Web Client. This is bundled in Purity 5.0, so if …

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 …

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 …
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 …
Migrating VMDKs or virtual mode RDMs to VVols is easy: Storage vMotion. No downtime, no pre-creating of volumes. Simple and fast. But physical mode RDMs are a bit different. As we all begrudgingly admit there are still more than a few Raw Device Mappings out there in VMware environments. Two primary use cases: Microsoft Clustering. …
Hey all–in case you didn’t get a chance to go to VMworld and would like to see my sessions live (well online live) and ask questions I am repeating them somewhat via the VMUG webinars. First one is on October 9th: This is a deep dive on the love story that is ESXi and UNMAP. …
Virtual Volumes change quite a lot of things. One of these is how your storage volumes are actually connected. This change is necessitated for two reasons: Scale. Traditional ESXi SCSI limits how many SCSI devices can be seen at once. 256 in 6.0 and earlier and 512 in 6.5. This is still not enough when …
I’m back from VMworld 2017 US and then VMworld Europe and a nice vacation. Time to get back to work and of course some (well a lot hopefully) blogging. Had a great time catching up with friends at VMworld and talking about the new stuff that both Pure Storage and VMware have coming. I had …
Here we go with another in-guest UNMAP post. See other posts here: https://www.codyhosterman.com/pure-storage-vmware-overview/flasharray-and-vmware-best-practices/space-reclamationunmap/ I was asked the following question the other day “does in-guest UNMAP work when snapshots exist?” To save you a long read: it does not work. But if you are interested in the details and my testing, read on. My initial answer was …
Hey all! A little late to post this, but I was waiting for my last two sessions to appear on the VMworld Content Catalog, which they just did. Really excited for my sessions this year, so hopefully you will agree! So let’s get to it.I have five sessions this year, all can be found here: …
