I had a question last week, and it had me going for a while. The question was if “das.perHostConcurrentFailoversLimit” could be used to lower the hit on storage during a boot storm. By default this advanced option is set to 32. Meaning that a max of 32 VMs will be restarted by HA on a single host. The question was [...]

Cluster Sizes – vSphere 5 style!?

Duncan Epping — Tue, 10 Apr 2012 18:30:37 +0000

The number of vSphere HA heartbeat datastores for this host is 1 which is less than required 2

Duncan Epping — Thu, 05 Apr 2012 10:44:31 +0000

Today I noticed a lot of people end-up on my blog by searching for an error which has got to do with HA heartbeat datastores. Heartbeat datastores were introduced in vSphere 5.0 (vCenter 5.0 actually as that is where the HA agent comes from!!) and I described what it is and where it comes in to play in my HA [...]
