Michael,
If it were me, I'd be looking at 2 - 4 GB of memory, today.
If it were me, I'd be looking at about 300GB of disk capacity in a RAID-5
configuration (at the 3-year mark and at 30% growth per year, I need no less
than 165 GB, not including parity). RAID-5 has two writes per database
write; RAID-6 has three. I'm not of the opinion that it provides an
additional level of protection worthy of that performance hit.
There have been other posts regarding OS limitations, so I shall not offer
my opinion there.
As the server approaches it's second anniversary, I would be budgeting
additional monies for an upgrade (not a replacement, but add more disk and
memory) during it's third year. If it's a one-shot deal, then I'd shoot for
8 GB of memory, an OS that'll let me use it, a multi-core processor, and no
less than 800 GB of storage (7 years of 30% growth has me near 500 GB, sans
parity).
Regards,
Bob Wyatt
