Can you install a SATA RAID 4 port/drive Controller into an existing VMWARE 4.1 ESXi Installation and move everything to the RAID Drives?
I was testing out a configuration and in doing so I started off with a single sata drive and will have 4-6 VMs on it and that's all working fine.
I'd like to give the system resiliency and use a RAID 5 or 10, or necessary RAID 1 with 2 2TB Drives
Would I be able to introduce a raid controller at this point and transfer everything to the drives on the RAID?
If so, how do I transfer everything to those drives? Or would I have to do a NEW ESXi installation, and then restore the VM's?
I am also trying to see what RAID controllers are specifically compatible with ESXi 4.1, I am getting cross eyed looking at various HCLs and cross referencing the configurations to determine whether or not it would or MIGHT be compatible.
I am not looking for a high performance solution as this will be a LOW demand ESXi box with only 4-5 XP machines running on them, I was looking into entry level SATA promise and adaptec controllers and as mentioned previously, I could go down to 2 port, raid 1 vs larger raid 5/10 configurations.
