Catch me at a VMUG in early 2018

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…

Registering the Pure Storage VASA Provider

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…

A new vSAN training class – vSAN Production Operations – now available

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…

Validating overlay network when docker swarm running on Centos VMs on vSphere

I got a chance to revisit my docker swarm deployment this week after a bit of a break. I was a little curious about my setup because when I spoke to some of our ‘Project Hatchway‘ engineers, I was told that I should be able to launch a single instance of Nginx in Docker Swarm (“docker service create –replicas 1 -p 8080:80 –name web nginx”) and I should be able to access the web service using the following command from any swarm node – “curl 127.0.0.1:8080”. This was not what I was seeing. When I launched the Nginx service, the…

Simple test for Docker Swarm functionality with Photon OS

After highlighting how easy it is to run docker swarm in Photon OS, I had a follow on question on how easy it would be to test the functionality. Just to recap, the only additional step you need to get Docker Swarm running on Photon OS was to open port 2377 on the master node. After that, you simply initialize the master, and all the other nodes/VMs are added as swarm workers. You might be wondering if you need to do a bunch of other stuff in iptables for docker, but the answer is no (for this relatively simple test…

A closer look at ECS (Elastic Cloud Storage) running on vSAN

This week I had the opportunity to take a closer look at ECS, the Elastic Cloud Storage product from DELL-EMC. ECS normally ships as a physical appliance, composed of multiple nodes/servers, but there is also a community edition available which is FREE with no time limit for non-production use. You can download it from here, and deploy it across VMs. Now I’ve already been looking at various ways to provide an S3 object store on top of vSAN, such as MinIO and Scality. What is interesting about ECS is that not only can it provide you with an S3 object…

Project Hatchway hitting the mainstream – persistent storage for containers

Regular readers will be aware that I “dabble” from time to time in the world of Cloud Native Apps. For me, a lot of this dabbling is trying to figure out how I can go about providing persistent storage to container based applications. Typically this in the shape of container volumes that are carved out of the underlying storage infrastructure, whether that is VMFS, NFS, vSAN or even Virtual Volumes. VMware Project Hatchway has enabled me to do this on multiple occasions. Project Hatchway was officially announced at VMworld 2017, but I’ve been working with this team since the early…
