For my non-production ESX cluster, I don't set any reservations. BUT for my Production cluster, I have set reservations in the past (at another company). Wondering of there is a way to automate this?
- Citrix VMs - Set memory reservation to 100%
- Application *** VM(s) - Set memory reservation to Peak (or XX% of peak) memory from the last month or X period of time.
I try very hard NOT to set any CPU reservations. For VMware, CPU contention is usually NOT an issue.
