I don't have a UPS, but the server has a redundant power
supply which is connected to two separate power circuits. so if
one goes out, no big deal. in addition, the 9500-12MI controller
has a battery-backup unit (BBU) installed to preserve the write
cache in case of a power failure.
if you're concerned about power failures when using 3ware
cards, I recommend turning off the write cache, or using a BBU
(costs about $100) if you're using a 95XX-series controller.
Yes. First flush at shutdown then immediately following a switch-
off of the cache.
Did you get the webserver management software to run? I couldn't,
it always crashed. But the console client works. Some scripting and
polling every 30 minutes and it sends emails on alerts and
failures. But the 3ware webserver would be more convenient, at
least a bit I think.
I, too, have had difficulty on older Gentoo systems with a 2.4.x
kernel.
the latest release of 3DM2 (9.3.0.4) seems to have corrected a lot
of issues when run with 7-8xxx controllers. I have a few systems with
8006-2 controllers and one with a 7506-4 that have 3DM2 running
happily. but all those are running 2.6.x kernels... so I'm not sure
if there are still issues with 3DM2 on 2.4.x kernels.
cheers,
