For the best database-write performance on the DL380G4, make sure you

Never heard of it. I'd take it as a hardware setup in BIOS?
(The server is in co-location, i have no physical access to it but i can
explain ISP sys-admin what to do if needed)
The more spindles you have, the better. Are you using all 6 drive
bays in the 380? Make sure they're all Ultra320 drives. 15K will
give the best performance, but the 10K drives aren't too shabby.
RAID0 will give the best performance, but it's not redundant. Next is
RAID1, then RAID5 or ADG.
I have 5 drives 36 GB Ultra320 15K:
2 mirrored drives mounted as /
3 RAID 5 drives mounted as /var
www# df -h
Filesystem Size Used Avail Capacity Mounted on
/dev/da0s1a 33G 4.7G 26G 16% /
devfs 1.0K 1.0K 0B 100% /dev
/dev/da1s1d 62G 9.5G 47G 17% /var
You might also try a DL385 (dual socket Opteron) or DL585 (quad socket
Opteron) which will give you either 4 or 8 procs (if they are dual
core).
Are you suggesting AMD based boxes outperforms Intel based machines?
That's what I'm really interested in...
I know it's time for a dedicated fast database server.
If i optimized my database and hardware settings, i could gain months,
not more.
The question is upgrade to what (Assuming my DL380 isn't enough)
Thanks,
