Hi,
We are running a cluster of ESXi 5.1 hosts - 2 of them are Xeon E7440 @ 2.4GHz (64GB RAM) and 1 of them is Xeon X5460 @ 3.16GHz (32GB RAM).
Currently, the memory utilization of all three ESXi hosts are around 60%.
We are going to replace the Xeon X5460 Server with a new physical server. We would like to seek your advice how much RAM should be ordered (My manager concerns the cost of the new server).
Thanks
Hi again Tony,
Hello,
since the cluster should have all its hosts identical CPU-wise (core count & frequency) and Memory-Wise (at least Size), you should order a host with 64 GB RAM.
Dear Alistar,
1) Does 60% RAM Utilization for ESXi Host is high ?
2) Would there be any problem if we add more RAM to the new server ? This is because my supervisor will not consider replacing the remaining two servers in the future AND I would like to boost the RAM presented to the cluster.
3) If we need to get the server CPU - Same core and frequency, I think it will be a good idea to ask vendor to give us suggestion on which model they think fits our situation.
Thanks
