Greetings all,

My local sun rep quoted me two of these servers recently, but was concerned
about the non-redundant power supply. Does this strike anyone as a single
point of failure? What risks would there be in using this in an enterprise
datacenter? Could they be mitigated?

We typically plug a dual power supply system into two electric circuits. We
could plug each server into different circuits, but is that mitigating risk
or sticking my head in the sand?

Any ideas or thoughts appreciated.

James

One more thing, this is for a pair of Oracle 9iAS application servers
running RH AS 3, load-balanced by Cisco CSS 11500.

Yes.

The risk is obvious: is the PSU loses its magic smoke, that machine
is dead.

The latter. Using two circuits guards against one of those circuits
going boom, but it doen't do anything about the PSUs in individual
machines.

If being without a SPF is important to you, the V20z is not the
machine for you. I think the V240 is the smallest dual PSU machine
from Sun.

Actually, the V65x has a redundant power supply option, and is also intel
based so he can run RedHat

Why would he want to do that (as opposed to Solaris)?

Agreed, if the v65x meets the OP's other requirements, that might
be the best machine to go for.

Because his intention was to use Red Hat Enterprise Linux. He was just
after Sun's hardware.

I appreciate everyone's input. Thanks.
