Just replied to another poster but wanted to respond to this thread as
well...
Joe,
Huge thanks for the pointer to the new firmware... I had a page
bookmarked for the 2950 firmware but the bookmark went to an old page.
We are running 16G machines, dual core, dual CPU, RAID 5 on Perc5i. Th
Thanks Greg,
Is there documentation or tests of the number of commands per LUN that
the hardware can handle? The driver is clearly reading the value out of
a register on the card.
thanks,
joe

HTH,
Greg

(across almost 20 machines). I am seeing it on ext3 (we migrated all of
the machines from XFS) and with ReadAhead disabled.
You mention a firmware update but I don't see any new PERC 5 firmware
packages on Dell's site... c
