Video of HCI Spotlight Session from #VMworld now available #HCI3551KE

This week at VMworld in Barcelona, I was honored to  be able to  co-present the HCIBU Spotlight Session with our GM and SVP, John Gilmartin. I noticed that the full video is now available online on the VMworld Video site. If you want to learn more about how to Future Proof your Infrastructure with vSAN and VMware Cloud Foundation, give it a watch. The cool demos, showing Cloud Native Storage, Site Recovery Manager support for vVols and Project Magna auto-tuning vSAN all start around the 30 minute mark. The full video is available here. Enjoy!

Site Recovery Manager support for vVols – Tech Preview from VMworld 2019

Regular readers will be aware that I have been spending a lot of my time on Cloud Native Storage topics these days, whether it is bubbling up how Kubernetes clusters are consuming vSphere storage through our new CNS feature in vSphere 6.7U3, or using Velero to do lots of things like backups/restores/application mobility. However something I have been passionate about for quite a number of years now is our Virtual Volumes (vVols) feature. And while it has been rather quiet over the past couple of years, I was thrilled to see us deliver a tech preview for supporting Site Recovery…

Which policy changes can trigger a rebuild on vSAN?

Some time ago, I wrote about which policy changes can trigger a rebuild of an object. This came up again recently, as it was something that Duncan and I covered in our VMworld 2017 session on top 10 vSAN considerations. In the original post (which is over 3 years old now), I highlighted items like increasing the stripe width, growing the read cache reservation (relevant only to hybrid vSAN) and changing FTT when the read cache reservation is non-zero (again only relevant to hybrid vSAN) which led to a rebuild of the object (or components within the object). The other…

A closer look at Portworx

Last month I had the opportunity to attend DockerCon17. One of the break-out sessions that I attended was from a company called Portworx. Portworx provide a solution for stateful docker container storage, which is what caught my interest. There are lots of companies who have already created docker volume plugins for their existing storage solutions, including VMware. However Portworx seem to be approaching this a bit differently, and are providing a layer of abstraction from the underlying host storage. So you might be using cloud (e.g. EBS from AWS), or SAN or NAS or indeed you might only have local…

A closer look at Cohesity 4.0

Last week, I had a chance to catch up with my pal, Rawlinson Rivera. Rawlinson and I worked closely on a lot of storage related stuff at VMware, but he has since moved on to pastures new, and is currently the CTO for the Global Field over at Cohesity. I’ve written about Cohesity a number of times on this blog. I think the first time I wrote about them was during VMworld 2015, just before the 1.0 product launched, and they were still pitching the idea of secondary storage and how they would take care of things like snaps, clones,…

Erasure Coding and Quorum on vSAN

I was looking at the layout of RAID-5 object configuration the other day, and while these objects were deployed on vSAN with 4 components, something caught my eye. It wasn’t the fact that there were 4 components, which is what one would expect since we implement RAID-5 as a 3+1, i.e. 3 data segments and 1 parity segment. No, what caught my eye was that one of the components had a different vote count. Now, RAID-5 and RAID-6 erasure coding configurations are not the same as RAID-1. With RAID-1, we deploy multiple copies of the data depending on how many…

A closer look at Rubrik Cloud Data Management v3.1

When I started to write this post, I looked back over my notes from previous conversations with the team at Rubrik and realized that my first conversation with them was almost 2 years ago. How time flies! I still remember meeting Rubrik at one of our VMware Partner Exchanges (PEX) in 2015, and getting a demo from Bipul Sinha (Rubrik CEO) and Julia Lee (Product Marketing). I also remember when Chris Wahl moved to Rubrik (almost 18 months ago now), thinking what a great move that was for both Chris and Rubrik. Well, when I caught up with Chris last…
