Hi all,
Our infrastructure is configured with 1 Cluster of 8 hosts on DRS fully automated (5 Resource Pools)- . Each host (Dell R710 - ESX4.1U1) has 64Gb of memory. The usage on each host is reaching the limit. 3 hosts today have triggered a warning alarm of > 85% RAM usage.
Having said that, all hosts are running on High State and no balloning or swapping has been triggered yet (monitoring stats from esxtop). This morning's vCheck report showed that 2 hosts have 2058Mb memory overcommitted.
I was wondering what I could pro-actively do in terms of preventing issues with VMs/hosts.
We have already ordered more RAM from Dell to upgrade all hosts anyway, as memory prices are really low at the moment.
Any comments or suggestions are much appreciated.
