I think with the current PE R320 and PE R805, that we are probably set, but
thank you for your offer. The R320 is a pretty new box, hmm, pulling the
serial # and going to Dell, it looks like it is only 16 months old. Jeff
mentioned they had some more coming out of cycle, and that people were looking
to get a hot spare at the UG meeting?
I think the specific problem I was seeing with the old hardware was
due to a very specific configuration. With the PERC6/i battery backed
up RAID controller, and some combination due to the age of the battery,
and that specific design, which periodically (every 2-3 months or so) does
a deep drain and charge cycle on the battery to make sure it can hold its'
intended charge for the writeback log, during this cycle it switches the
writeback log off and then on again, and sometimes the OS glitches on this
sudden change in disk latency. My guess is the batteries were below a certain
threshold point that exacerbated the writelog switchover, since we have been
running on the same hardware for quite some time without issues, but not
below the threshold which would alert the BCM on the RAID battery being bad.
Both of these new systems do not have a battery backed up RAID system, which
really isn't needed in this use case anyway, and are newer hardware, which I
think would serve us well.
I have both inhouse, with the OS installed, I just have to copy the configs back over,
which I can get done pretty quickly, as it isn't extensive, and haul them down
to 511. I'll have to schedule up some sort of switchout time, how much lead time
would a graceful changeout of the hardware be required?
