Thank you all for your help so far, and thanks again to VMWare for releasing ESXI!
A few more questions if thats ok.
1) Essentially, the server I want to purchase for my virtualisaion environment is the Acer Altos R520:
This system in the VMWare HCL, so does this mean that it's pretty much guaranteed to work? Does it matter what type of SATA hard-disks I place inside it, or do they also have to pass the HCL?
2) The system comes with a Intel Embedded Server RAID for SATA software RAID levels. I'm assuming as ESXI is a very 'thin' host, it doesnt support software RAID and thus can't be used (If 8 SATA disks are inserted, then the system will just see them as eight seperate drives?)
3) Is it worth forgetting about SATA anyhow and just using SAS?
Lot of questions
1. If you use a hard disk in HCL, that'll be better choice;
2. If the RAID is not in the HCL, it is not guranteed;
3. No muchdifference for basic usage between SATA and SAS;
1.- If the HW is in the HCL...it should work
2.- ESXi or ESX doesn´t support software RAID or just few of them: i have 1 ESXi with 2 discs without RAID -> i have installed ESXi manually in both (same config) and later i am doing backup restore form the active disk to the other
3.- Regarding the disk tipes...depends on yout budget
