Thanks for all the great info.. your details on the homebuilt system
are great.
Not far off from the preliminary plans I've made.
My price of $3200 was for a rackmount server.. as we dont have the
space for any more towers.. we are getting a 42U rackmount 4 post
cabinet within a week, I already have a 3U rackmount server jerry
rigged in the bottom of the existing 2 post unit. We have 4 total
servers now (and 1 DC).. the 4 servers would go over ethernet...
Do I need a special kind of nic card to be able to use the jumbo frames
options.. as I dont see this on any of our existing NICs on any of the
servers. I also have a 48 port gigabit managed switch, I bet it has
these options on it though.
Like I said our full load at full backup time is 800 or so , but my a
month's end before the next one after incrementals we are at 1.1TB.. so
for the backup server I was planning on purchasing Seagate 400GB drives
(I dont think they were enterprise class, I'm still unclear on the real
advantage there? Though I agree.. I like Seagate better as far as
reliability).. I was going to put 5 of these in RAID5 giving 2 TB of
space (goal for all of this being to last 3 years at least). the
seagate I was going with: SATAII 3 Gbps.
So I had priced the WoodCrest CPU ($384).. the Ram 2x1gb PC2640 DDR2
667($329).. The 5 400 GB HDs and 2 mirrored 120gb OS drives ($950).
The motherboard Asus DSBV-D $339, finally the 3ware card 3ware
9590SE-8ML $484 and then the SATAII 2U server case at $689 (with mini
sas/ncq) ability.
Maybe the cpu/motherboard is overpriced but I want longevity..
And then ill use the exebyte magnum 224 lto3 (upgradable to lto4) for
offsite backup via u320 scsi...
