Hi,
I'm building an ESXi box for home on a Lenovo D10 workstation, I'm getting a Dell Perc 5i controller for it which is dual channel and I'll be buying 4 1TB SATA disks for storage.
My question is since I will have multiple VM's across the storage:
Am I better to use two disks per channel - then mirror each two disk set into a mirrored RAID 1 set? (so will have similar to single drive performance but will lower the amount of I/O to each disk since VM's will be placed on one VMFS or the other..)
OR
Create a single RAID10 set using all 4 disks on one channel? (so will have close to striped performance but multiple VM's on the same VMFS..)
OR
am I able to split the disks across both channels and still create a RAID10 set? - any pro's or con's to doing this (-if it can be done)?
in terms of capacity - 2TB will be more than enough capacity for my purposes for the VM's I need, they will be running things like SQL / Exchange / Altiris / ConfigMgr etc for testing and lab purposes only.
also any recommendations on what 1TB SATA hard drives perform best for RAID? I've read some aren't designed to be used in RAID?
