Hi, I would like to know about wheter it would suffice
for a two-node RHCS cluster a single power switch (APC 7921) fencing device. The
power switch has 8 power outlets and I intend to use four of them for each
node's dual power supplies. I know it would be desirable to have two devices for
a fully redundant configuration, but after reading some examples from the docs
(they are meant for two power switch), I still cannot understand why a single
power switch connected to both servers and the switch taking power from the
UPS, would not be a good configuration. There is a single UPS in the
environment. ¿any experiences over this issue? regards, alvaro |
