snagrat Posted July 25, 2016 Posted July 25, 2016 So I have 8 servers in a blade. 6 are identical in spec and the other 2 are slightly different. Currently I have them setup as 4 Failover clusters but am wondering if this is best? Should I just have one big cluster of all 8 servers? What do people think?
PotNoodleTech Posted July 26, 2016 Posted July 26, 2016 The whole point of a cluster is that a host can failover to another host in the cluster with no fuss. I don't really see the point of creating more than one cluster and running them along side each other? So yes, I would have one big cluster with you're 8 hosts as members. The different specs only mater if the spec of the lesser server can not run all of the VMS due to RAM/CPU limitations, e.g. you have 20VMs that use 80GB ram and two of you're hosts only have 24GB ram - then you could potentially have a problem (even though it's unlikely that all VMs would need to run at the same time on the weak hosts, it could theoretically happen).
snagrat Posted July 26, 2016 Author Posted July 26, 2016 All hosts have 64GB ram but in total all the VMs will use more than that. Like you said though realistically they won't all be down at the same time
