Calculating HA for a vCenter, vSphere 4 Enterprise 20 CPU licence
Two Blades HP
- BL 460c G1 x 16 GB RAM
- Intel E5420
- Processor Sockets 2
- Core per Socket 4
- Logical processors 8
- Hyper threading not available.
I would like to implement HA
I have the following requirements - 8 Servers
- 2 vCPU / 6 GB RAM – running
- 2vCPU / 4 GB RAM – running
- 8vCPU / 10 GB RAM – running
- 4 vCPU / 4 GB RAM – still to be provisioned
- 2 vCPU / 2 GB RAM– still to be provisioned
- 2 vCPU / 2GB RAM – running
- 4 vCPU / 4 GB RAM– still to be provisioned
- 2vCPU / 4 GB RAM – running
Total of 36 GB RAM required, currenlty have 16 GB per server.
I currently have 16 GB and when I check my slot allocation it says 5 used and 5 available with a total of 20 ? How do I calculate the minimum amount of RAM required for HA? and the fact that I have a system with 8vCPU when this system moves over to the one host will I need to drop the vCPU to better accomodate the schedular ?
Thanks for your help,
