Hi,



I have a DL380 G4 with Integrated Smart Array 6i Controller attached to 6 Ultra320 SCSI 10K Drives in a RAID5 Array and am experiencing write performance on average of 6MB/s.



I understand that write performance is sub optimal on a RAID 5 array but 6MB/s seems very slow? I have a SmartArray 6402 controller which I can upgrade to, will this improve perofmance? or is 6MB/s about as good as it will get in RAID 5?



Thanks

Matt
 
That does seem very slow.
Does the 6i have a BBWC (battery backed write cache) module. How much cache RAM does it have?
