You could always swap it out for an HP server?
Heehee! Kidding!

Subject: [suse-oracle] Heavy I/O causes servers to become unusable
We have Oracle databases and applications running on IBM servers --
SLES8 on our apps server and SLES9 on our db servers.
We have our development servers setup with RAID 5.
We find that when I perform heavy I/O such as copying a database or
applying patches or upgrades, the servers become unusable. TOP will
show CPU idle of 35 - 50 % but a load average or 10 - 15. This happens
on internal disks as well as disks on our EMC Clarion so we suspect it
is more of a server or OS issue.
I have been a dba for 12 years and have performed the same operations on
HP and Sun Solaris. On Sun and HP, I would see the server become slow,
but not unusable.
Does anyone have any suggestions?
