> What settings are there on the cache? I have a DL 380 G5 with 2 x

The RAID cards on the original machines came with the cache configured
as 50/50 read/write split. The new ones came configured 25/75 read/write
splitl. Having set them all to 50/50 using the Smart Start CD then I now
get iidentical performnce. It's worth checking - these RAID controllers
have shoipped set to 50/50 for as long as I have been using them, so I just
assumed the new ones would be too...
