Hello all; I have a question regarding replacing older Sun servers,
particularly regarding CPU horsepower.
Here's a for instance: We have a couple of 420R servers, with 4 GB Ram
and 4 X 450MHz CPUs. In spec-ing replacements, I'm looking at V440
servers. Since RAM is (relatively) cheap, I'm gonna spec the same
amount of RAM, but CPUs are a different story. I can simply spec them
with 4 CPUs, but on this model, the CPUs range from 1 GHz to 1.5 GHz.
Plus, the price jump from 2 to 4 CPUs is about 10 grand (list, of
Can I simply say "well, 4 X 450 GHz is 1800 GHz, so I'll spec them with
2 X 1.5 GHz CPUs for a total of 3 GHz of CPU power, and we'll be set
for the current load, and have room for growth before we have to add
I know, I know, I should have some stats gathered to gauge how well our
4 CPUs are doing for us now, but this was sprung on me last minute, and
I need to get rough numbers to management ASAP.
Any assistance, rules of thumb, or other advice gratefully
acknowledged, as always.
