Thank you for your interest,
I'll test the system with a bigger power supply. But under full load
(cpu, disk and network) these systems consume about 70 watts.
They are powered by either an antec earthwatt 380W or a
seasonic something energy efficient. The antec also powers an opensolaris
server with 7 disks on a sb700 without a problem.
There's one other thing, I did mentioned, the error occurs on both disks.
Although one channel gets more errors than the other. This behaviour is
the same on all three machines.
I'll arrange a couple of seagates to test if it's limited to the
western digital disks.
Currently I'm running the vm's on a nfs share, keep my fingers crossed, no
disk power cycles. But I'll have to test that a bit longer.
I'll be away till next tuesday so please be patient for my results.
Regards,
Wessels
