I am currently planning to replace our existing hyper-v cluster, running on an old EMC SAN and two HP gen8 servers. I’d like to utilize fault tolerance in ESXi 6.7. I’m new to VMware clusters.
* **SAN**: an all-flash offering from iXSystems (x10ha), Dell (Powervault ME4024) or HP Nimble. SAN will have ~15TB usable space.
* **Servers**: Two PowerEdge R640’s, 192gb RAM, single Xeon 4216, and Intel x520 4-port nics. I will be running 25 VM’s max, each host will be able to handle the load of all of my VM’s in the event of a host failure. I might add a third host in the future if our needs increase. VM requirements are low. Mostly basic windows/linux vms. May add an RDS soon.
* **Switching**: Two Cisco Nexus 3k switches, with redundant 10gb links to hosts/san.
My questions are:
Is there anything in the above config that is against best practice or that might cause issues? Any pros have recommendations that might improve this setup?
Seems like i’ll need vSphere Enterprise Plus licenses to handle FT on vm’s with more than 2 vCPUs. Im guessing i still have to license both hosts? nearly 8k for those licenses is a lot!
