I am configuring RAID arrays for a HP Proliant server running Windows Server 2008. We will probably use RAID10 configurations, but split it to several logical drives.
Is it reasonable to create a single dedicated RAID 0 logical drive just for the swap file?
Here is our system info:
- HP Proliant ML350 G6
- 1x Intel Xeon E5520 4 core
- 6Gb RAM PC3 UDIMM
- P410i HW RAID controller + 512MB BBWC
- 4x 1.5Tb SATA
- Windows Server 2008 R2 Enterprise
Ok, at the end I realized I was talking nonsense.
Since I was planning to use RAID10 for these 4 disks anyway (write speed 2x, read speed 4x), I realized it didn't seem too justified to make a small RAID0 partition for the relatively small benefit I get (write 4x, read 4x) compared to the mess I would end up with if one of my disks would die.
My idea was something like this:
- RAID array: 4x1.5Tb.
- 1st logical disk: 4x16Gb RAID0 for swap
- 2nd logical disk: 4x1.3Tb RAID10 for everything else
Once you create an Array out of these 4 physical disks, HP P410i allows creating several RAID setups which can utilize them partially.
Never mind, I will simply use RAID10 and have a reasonably fast, but much safer machine.
