Have an infrastructure question , hope some one will suggest a good solution.
Client has 6 esxi hosts in a cluster.
Two of the servers are with 4 core dual CPU.
Three of them are with 8 core dual cpu.
One of them is with 12 core dual cpu and the memories are not equal in the esxi hosts too, this case the DRS is unbalanced status.
It is time for them to get replaced the old servers with new server possibly upgrade the vsphere to ver6.0
Definitely the three servers with 4 core require immediate attention (replace).
i suggested my client to replace with 8 core dual cpu so the cluster will be in balance, that is, all the servers will have almost same cpu and memory.
The system admin prefers to get latest server 12 or 18 core, this case the cluster will have three 18 core, two 8 core and one 12 core.
And He said that he can set affinity rule so his tier -1 servers will be staying on the 18 core esxi hosts and he does not need to worry about failure of a single host, that is, the cluster will still have two more 18core servers to fail over.
i suggested him that if you are not going to have a vm with 32vcpu or more why you bother you want to spend money on 18 core instead stay with 8 core.
What you will suggest if you are in my situation?
