Hey folks,
We've got some new hardware and are trying to figure out what best to do with it. Either run CentOS right on the bare metal, or virtualize, or several combination options. Mainly looking at :
- CentOS on bare metal
- CentOS on ESXi 4.0 with local disk
- CentOS on ESXi with 1 VM running Openfiler to serve disk to other VMs
And want to benchmark these 3 scenarios
Save yourself some trouble and skip the last one. Running openfiler in a VM to serve disk to other VM's is a crazy idea.
Save yourself more trouble and think about what your going to use the system for, if it is(or will be) a multi purpose system, then go with ESXi, if it's a single purpose system go with bare metal.
ESX has maximum efficiency with 1 vCPU VMs, so if you have 8 cores, you should have at least 8 VMs running.
