There is one very important quirk that I need to report. The
dual opteron reports 4,096MB of ram, as expected.
However, the two Pentium IV servers with 4 physical gig of RAM in them
report only 3,584MB of RAM. I fiddled with the chips to confirm that
each of them really is 1 Gig, and that's not it. I also poked around
in the bios (in an uneducated manner), but saw nothing to fix.
Here's the setup... I haven't yet physically labelled the machines
with their names. This list starts with the Opteron and goes up in ip
numbers by one.
2U Opteron - 4 gig of ram
1 - 2
1 - 2
1 - 4
1 - 4
1 - 1
1 - 1
1 - 1
1 - 1
The idea is that for now, we'll have 2 squids, 2 webservers, and 1
database server. The other 4 machines with 1 gig of ram could be
pressed into service with or without ram upgrades, or can be used
as-is for auxiliary services. At least one is going to be the mail
server, and probably another will be the nameserver.
memtest86 will run overnight, and if (as I expect) all goes well, we
will be ready for production tomorrow. If the machines can only
recognize 3.5GB of RAM instead of 4, that isn't a joyful thing, but
it really doesn't matter a LOT, I don't think.
