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 […]

At VMworld, there were various sessions with vSAN Customers, many of which I have met in some shape or form in the past couple of years. Some of these stories contain some great use cases or stories.

vMSC and Disk.AutoremoveOnPDL on vSphere 6.x and higher


Advertise here with BSA

I have discussed this topic a couple of times, and want to inform people about a recent change in recommendation. In the past when deploying a stretched cluster (vMSC) it was recommended by most storage vendors and by VMware to set Disk.AutoremoveOnPDL to 0. This basically disabled the feature that automatically removes LUNs which are […]

One versus multiple VSAN disk groups per host


Advertise here with BSA

I received two questions on the same topic this week so I figured it would make sense to write something up quickly. The questions were around an architectural decision for VSAN, one versus multiple VSAN disk groups per host. I have explained the concept of disk groups already in various posts but in short this […]
