Might be cool, but I don't know what we would use virtualization
for.
You can upgrade and migrate between instances when we need to install
new versions rather than praying the reboot will work. That's the big
one. And, if the new one doesn't work, you just turn the old instance
back on.
I'd like to see ECC RAM given the size we are using, but the
premium probably isn't worth it.
If we get a server class board, which would be my preference, they
only accept ECC RAM.
That's fine by me.
Well, once we have enough RAM installed, we may find that drive IO is
the bottleneck, which is usually is. I would prefer we spend our
money on something that won't need to be replaced or upgraded for a
few years.
Clarify, please.
At this point, SATA-2 has better throughput than SCSI. *Each* disk gets
a 300MB/s connection. To beat that you need FC-AL 4Gb or Ultra 640-SCSI.
The drives are 7200 RPM. The benefit there is less heat and more
capacity. If we go with SCSI 10K's, the heat goes up. However, you can
get 10K SATA-2 drives. Now, if you *really* want 15K's, that's different.
Finally, just about any software RAID solution is going to stomp all
over just about any inexpensive hardware RAID solution. In addition, it
is *much* more compatible when we finally do decide to upgrade.
