Scaling out your vSAN File Services Cluster


Advertise here with BSA

This week I have been testing with vSAN File Services and one of the procedures I wanted to run through was scaling out my vSAN File Services cluster. In my case, I have a cluster of 5 hosts and what I want to do is add a host to my vSAN cluster, expand the vSAN […] Continue reading

Creating a vSAN 7.0 Stretched Cluster


Advertise here with BSA

A while ago I wrote this article and created this demo showing the creation of a vSAN Stretched Cluster. I bumped into the article/video today when I was looking for something and figured that it is time to recreate the vSAN Stretched Cluster demo. I recorded it today, using vSphere / vSAN 7, and just […] Continue reading

vSAN/DRS awareness to be introduced in vSAN/vSphere 7.0!


Advertise here with BSA

It was briefly mentioned here, but I figured I would elaborate on this new cool feature for vSAN Stretched Clusters which is DRS Awareness of vSAN Stretched Clusters. So what does this mean? Well, it is fairly straight forward. DRS will take vSAN resync traffic into consideration when the DRS algorithm runs. I can probably […] Continue reading

Introducing vSAN File Services as part of vSAN 7.0


Advertise here with BSA

There was a great article by Cormac talking about vSAN File Services published last week. I had some articles planned, but hadn’t started yet, so when I saw the article I figured I would do something different. No point in rehashing what Cormac has already shared right. I figured I would shoot another demo, and […] Continue reading

Can I still provision VMs when a vSAN Stretched Cluster site has failed? Part II


Advertise here with BSA

3 years ago I wrote the following post: Can I still provision VMs when a VSAN Stretched Cluster site has failed? Last week I received a question on this subject, and although officially I am not supposed to work on vSAN in the upcoming three months I figured I could test this in the evening […] Continue reading

Part 2: Is VSA the future of Software Defined Storage? (Customer use case)


Advertise here with BSA

About 6.5 years ago I wrote this blog post around the future of Software-Defined Storage and if the VSA (virtual storage appliance) is the future for it. Last week at VMworld a customer reminded me of this article. Not because they read the article and pointed me back at it, but because they implemented what […] Continue reading

Project nanoEDGE aka tiny vSphere/vSAN supported configurations!


Advertise here with BSA

A few weeks ago VMware announced Project nanoEDGE on their blog virtual blocks. I had a whole bunch of questions the following days from customers and partners interested in understanding what it is and what it does. I personally prefer to call project nanoEDGE “a recipe”. In the recipe, it states which configuration would be […] Continue reading

2 node direct connect vSAN and error “vSphere HA agent on this host could not reach isolation address”


Advertise here with BSA

I’ve had this question over a dozen times now, so I figured I would add a quick pointer to my blog. What is causing the error “vSphere HA agent on this host could not reach isolation address” to pop up on a 2-node direct connect vSAN cluster? The answer is simple, when you have vSAN […] Continue reading

My recommended sessions for VMworld Europe 2019!


Advertise here with BSA

I created a list of recommended sessions for VMworld US, so I figured I would do the same for VMworld Europe. I am limiting it to 15 sessions for Europe and removed some of the sessions I had listed for the US and added some others for EMEA. I personally have 2 sessions scheduled at […] Continue reading

Capacity Overview in vSAN 6.7 U3


Advertise here with BSA

I just wanted to do a short post before the weekend, in vSAN 6.7 U3 there’s a great capacity overview screen. It shows a couple of things, first of all it provides a simple bar that shows “data written”, “reserved space” and “free space”. The second section provides you the ability to figure out what […] Continue reading
