Have a new DL380 G8 server that I'll be installing MS SQL 2012 on, under Windows 2008 R2. The DB/application in question is write heavy. I was wondering if anyone from HP, or others with experience, could provide me any recommendations on the configuration of the logical disks. I'm looking for the best performance for the write heavy SQL DB's/logs. I've read so many mixed opinions on how to configure these disks for the best performance, and everything starts with the hardware vendor recommendations. I'd like confirmation or opinions on how best to configure these disks.
Add-On Controller P420 Controller – 90% write, 10% read cache ratio
C: - OS, SQL Application, and Page File – 2x146GB – RAID1 – 64K Strip, 256K Full Stripe Size
E: - .LDF Log Files – 2x146GB – RAID1 – 64K Strip, 64K Full Stripe Size
G: - Backups – 2x450GB – RAID0 – 64K Strip, 128K Full Stripe Size
Built-In P420i Controller – 90% write, 10% read cache ratio
D: - .MDF Data Files – 4x450GB – RAID10 – 64K Strip, 128K Full Stripe Size
F: - TempDB Files – 2x300GB – RAID1 – 64K Strip, 64K Full Stripe Size
For all disks except C:
Partition offset configured for 64k. NTFS allocation unit size also set to 64k.
C: configured for 1024k offset and default allocation unit size.
Do these values make sense for what I am looking to do?
Thanks,
Tim
