We're running UV 10.2.7 on RH ES 5.1. The hardware is a pair of IBM
xSeries 3650s with 2GHz CPUs and 15K rpm hard drives configured in a
2-node HA cluster. The HA management software is LifeKeeper from
Steeleye. We've been running on this hardware since sometime in April,
and prior to that we ran UV 10.1.4 with RH AS 3.0 on a pair of IBM
xSeries 345s in the same 2-node HA setup for a little over 3 years. The
servers have been running contiuously since the upgrade:
14:58:19 up 139 days, 5:12, 52 users, load average: 0.05, 0.18, 0.17
There is one gotcha with terminal setup if you use ADDS Viewpoint
emulation. You'll want to make sure any Viewpoint users have the
following entry in their .bash_profile:
if tty --quiet; then
stty erase '^H'
stty susp undef
fi
Actually, the '^H' backspace fix is needed for any emulation, but
without the "susp undef" setting, Viewpoint terminal sessions with hang
if the up-arrow key is pressed.
We usually have around 100 terminal users at peak times, and probably
average around 30K UniObjects for Java connections per day from our web
site.
For backups we're currently using a disk-to-disk-to-tape appliance
solution from UniTrends. The UniTrends appliance dumps 200GB of UV
on-disk backups to a Certance (now Quantum) 8-slot LTO-2 autoloader at
the beginning of each month. We also do additional redundant backups
before and after our end-of-month batch processing to a 2TB NAS
appliance from Aberdeen. I just have a script that uses "cp -r" at the
OS level to copy to an NFS mount for those.
