vSphere HA Restart Priority


Advertise here with BSA

I’ve seen more and more questions popping up about vSphere HA Restart Priority lately. I figured I would write something about it. I already did in this post about what’s new in vSphere 6.5 and I did so in the Stretched Cluster guide. It has always been possible to set a restart priority for VMs, […]

Disable DRS for a VM


Advertise here with BSA

I have been having discussions with a customer who needs to disable DRS on a particular VM. I have written about disabling DRS for a host in the past, but not for a VM, well I probably have at some point but that was years ago. The goal here is to ensure that DRS won’t […]

Changing advanced vSphere FT related settings, is that supported?


Advertise here with BSA

This week I received a question around changing the values for vSphere FT related advanced settings. This customer is working on an environment where uptime is key. Of course the application layer is one side, but they also want to have additional availability from an infrastructure perspective. Which means vSphere HA and vSphere FT are […]

Using a vSphere custom TCP/IP Stack for iSCSI


Advertise here with BSA

I noticed a question today on an internal slack channel and it was about the use of custom TCP/IP stacks for iSCSI storage environments. Cormac and I updated a bunch of Core Storage whitepapers recently, and one of them was the iSCSI Best Practices white paper. It appears that this little section about routing and […]

Insufficient configured resources to satisfy the desired vSphere HA failover level


Advertise here with BSA

I was going over some of the VMTN threads and I noticed an issue brought up with Admission Control a while ago. Completely forgot about it until it was brought up again internally. With vSphere 6.5 and vSphere HA there seems to be a problem with some Admission Control Policies. When you for instance have […]

Using HA VM Component Protection in a mixed environment


Advertise here with BSA

I have some customers who are running both traditional storage and vSAN in the same environment. As most of you are aware, vSAN and VMCP do not go together at this point. So what does that mean for traditional storage, as in with traditional storage for certain storage failure scenarios you can benefit from VMCP. […]

vSphere HA heartbeat datastores, the isolation address and vSAN


Advertise here with BSA

I’ve written about vSAN and vSphere HA various times, but I don’t think this has been explicitly called out before. Cormac and I were doing some tests this week and noticed something. When we were looking at results I realized I described it in my HA book a long time ago, but it is so […]

Which disk controller to use for vSAN


Advertise here with BSA

I have many customers going through the plan and design phase for implementing a vSAN based infrastructure. Many of them have conversations with OEMs and this typically results in a set of recommendations in terms of which hardware to purchase. One thing that seems to be a recurring theme is the question which disk controller […]
