Kubernetes Storage on vSphere 101 – StatefulSet

In my last post we looked at creating a highly available application that used multiple Pods in Kubernetes with Deployments and ReplicaSets. However, this was only focused on Pods.  In this post, we will look at another way of creating highly available applications through the use of StatefulSets. The first question you will probably have is what is the difference between a Deployment (with ReplicaSets) and a StatefulSet. From a high level perspective, conceptually we can consider that the major difference is that a Deployment is involved in maintaining the desired number of Pods available for an application, whereas a…

New vRealize Automation, Cloud Assembly integration with SPBM

At VMworld last year, Duncan Epping and I presented on the power of Storage Policy Based Management (SPBM for short). You can find all of the slides and recordings here. One of the demos we used in the presentation was deploying virtual machines via vRealize Automation, and showing how to consume a storage policy on vSAN. This was using a vRealize Automation plugin, and to be honest, it was a little bit challenging to get it to work. And it wasn’t really a VMware plugin per-se, but something developed by our field team. Today, I’m pleased to announce that we…

A closer look at VVol snapshot policies on Pure Storage with vSphere 6.7

I am in the very fortunate position of having access to a Pure Storage array, and this has been recently updated to support Virtual Volumes. With my new 6.7 vSphere cluster, I finally found some time to take a closer look at Virtual Volume (VVol) snapshots on the Pure array, something that I have been meaning to do for some time. For those of you who are new to Virtual Volumes (VVols), one of the major advantages is the granularity at which certain operations can now be done. In the past, we were always dealing with data services at the…

Upcoming VMUG webinar – vSphere 6.5 Core Storage

A quick note to let you know that I am co-presenting on an upcoming VMUG webinar with my good pal, Cody Hosterman, from Pure Storage. The subject is vSphere 6.5 Core Storage, and this is very much the same topic that we presented at VMworld 2017. We will cover new limits, deed dive into VMFS-6 and VAAI enhancements (including automated UNMAP), cover what’s new in NFS and iSCSI, and then finish with an overview of what we’ve done in the NVMe space. The webinar takes place on Thursday, November 16, 2017 at 11:00 AM US Central Standard Time. Cody and…

View 7.1 and vSAN 6.6.1 interop – nice fix

Last week, I was rolling out Horizon View v7.1 on my new vSAN 6.6.1 all-flash configuration in the lab. Now, one of the pet peeves a few of us have had with this configuration was that a warning was always reported around read cache reservations on all-flash vSAN. Of course, read cache is irrelevant to all-flash (AF) configurations as it does not use a read cache; this is only applicable to hybrid vSAN configurations. This is why it was such as annoyance.

A closer look at the Infinio Cache Accelerator I/O Filter

The folks over at Infinio were kind enough to send me their latest Cache Accelerator I/O Filter so I could set it up in my lab. I must say, this seemed to be the most intuitive of the VAIO plugins (vSphere API for I/O Filters) that I have used to date. In this post, I just want to run run through the deployment of the filter, as opposed to looking at any of the potential performance benefits. If you want an overview of VAIO, have a read of the write-up that I did from VMworld 2014 here. I’ve also looked…

Norway VMware User Group Meetings – May/June 2017

I’m delighted to report that I’ve been invited to speak at the upcoming Norway VMUG (VMware User Group) meetings. These take place in three different cities over the week of May 29th (week 22), with three meetings in three days. On Tuesday, May 30th, the Oslo VMUG will take place. On May 31st, it’s the turn of the Trondheim VMUG and we will finish with the Bergen VMUG on June 1st. I am going to broaden the scope of the conversation at these VMUGs, and talk about Storage Policy Based Management (SPBM) in general. Of course, we will look at…
