Install and Configure vSphere Replication with SRM 8.3 on vSphere 7


Advertise here with BSA

I haven’t really done much with vSphere Replication and Site Recovery Manager (SRM) in the past years as my main focus has been vSAN. I figured I would get two clusters up and running and install and configure both vSphere Replication as well as SRM on top of vSphere 7. Although the installation and configuration […] 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

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

VMworld Reveals: Disaster Recovery / Business Continuity enhancements! (#HCI2894BU and #HBI3109BU)


Advertise here with BSA

At VMworld, various cool new technologies were previewed. In this series of articles, I will write about some of those previewed technologies. Unfortunately, I can’t cover them all as there are simply too many. This article is about enhancements in the business continuity/disaster recovery space. There were 2 sessions where futures were discussed, namely HCI2894BU […]

vSphere HA virtual machine failed to failover error on VMs in a partitioned cluster


Advertise here with BSA

I received two questions this week around partition scenarios where after the failure has been lifted some VMs display the error message “vSphere HA virtual machine failed to failover”. The question that then arises is: why did HA try to restart it, and why did it fail? Well, first of all, this is an error […]

How to test failure scenarios!


Advertise here with BSA

Almost on a weekly basis, I get a question about unexpected results during the testing of certain failure scenarios. I usually ask first if there’s a diagram that shows the current configuration. The answer is usually no. Then I would ask if they have a failure testing matrix that describes the failures they are introducing, […]

HA Admission Control Policy: Dedicated Failover Hosts


Advertise here with BSA

This week I received some questions on the topic of HA Admission Control. There was a customer that had a cluster configured with the dedicated failover host admission control policy and they had no clue why. This cluster had been around for a while and it was configured by a different admin, who had left […]

HA Admission control: How can I check how much reserved resources are used?


Advertise here with BSA

I had this question twice in the past three months, so somehow this is something which isn’t clear to everyone. With HA Admission Control you set aside capacity for fail-over scenarios, this is capacity which is reserved. But of course VMs also use reservations, how can you see what the total combined used reserved capacity […]
