- One (1) AMD Opteron Barcelona 2347 HE Quad-Core CPU @ 1.7 GHz.
- 8GB DDR2 RAM.
- Possibly four (4) 120GB hard disks, all in a RAID0+1 array or independent RAID 1 arrays.
- VMWare ESX Server
Here's what I have in mind:
- Right now, my Zimbra mail server is running on a AMD Athlon XP CPU at 1.8 GHz with 512 MB DDR RAM. I want to virtualize this, with two physical cores and 8GB of RAM dedicated to the VM. Question: Should I have the VM access a physical RAID array, which will require two 120GB disks mirroring each other, or should I just get two 250GB hard disks (in a RAID 1 array) and store the VMs on there? Am I looking at a serious performance difference between the two?
- I also have a file/vpn server running on a Intel Pentium III at 450 MHz with 192 MB PC100 SDRAM. (File servers do practically nothing; the most expensive use for it is RDP.) I want to virtualize this as well, with one core and 1 GB allocated to it. I don't want to give it too much RAM, since it really won't be doing anything other than serving up files and such. These disks will all be external, possibly connecting via USB.
So for the server heads on here, what do you think of the setup? Is it too powerful, or do I need to crank it to 11?
Thanks a lot.
