I’m sure it will come as no surprise to many readers that virtualization has brought (and continues to bring) huge benefits with regards to data center efficiency. I’m sure you are all aware of how virtualization allows you to do more with your servers; no more single server – single application paradigms. No longer do you have huge amount of compute resources left idle on your servers. By being able to run many operating systems and many applications simultaneously on the same single server (server consolidation), virtualization brought a halt to server sprawl and data center expansion for many of…
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…
Last week, I had the pleasure to attend our CTO Ambassadors conference, hosted by our Global Field CTO Chris Wolf. This was an excellent week, especially for someone like me who works directly for a single business unit at VMware. It gave me great insight into the activities going on in our other business units at VMware. One of the highlights for me was our “Serverless” night, where I finally got an opportunity to learn about Serverless, Functions As A Service (FaaS), AWS Lambda and all that other stuff that I kept hearing about, but did not quite fully understand.…
Well, I’m delighted to have been invited to present at quite a few VMUGs recently, so I thought I’d share the details of them with you here. I’ve been working on my presentation which is called “What is happening in the world of VMware Storage?”. In fact, there is a lot going on, not just in the world of vSAN and VVols, but also in core storage as well as in cloud native storage. So in my 1 hour slot, I’ll be trying to update you on all of this goodness. No easy task, but I’m always up for a…
Hot on the heels on Pure Storage’s recent announcement on Virtual Volume (VVol) support, I wanted to take a closer look at their VVol implementation for myself. Thanks to the support team over at Pure, they were able to very quickly update our lab array to the latest release that has support for VVols. Once this upgrade was complete (which was all done remotely), I wanted to go ahead and register the VASA provider with my vCenter server. You can read more about the role of VASA here. I wanted to step through the process manually, rather than use the…
There was lots of big news yesterday from our friends over at Pure Storage. First of all, we had an announcement about their Virtual Volume (VVol) implementation going GA. This is very exciting for me, and I look forward to testing it out in our lab. The implementation is a VASA 3.0 implementation, which means support for array based replication (ABR). My good pal Pete Fletcha did a great write-up on the announcement here. And of course, Cody Hosterman of Pure Storage also gives us his low-down on what this VVol implementation means to him. One thing is for sure,…
A short post today to let you know about a new VMware training class that I helped to create. This new class is called VMware vSAN Production Operations, and is a new 3 day class delivered by our Education Services division. As you can imagine from the title, this class is geared towards administrators who are responsible for managing vSAN on a daily basis in a production environment. The class focuses primarily on operational considerations such as storage policy change impacts, hardware monitoring and replacement, scaling up and scaling out the cluster, data services (e.g. encryption), maintenance mode considerations and…
