Direct to the motherboard, if the bios doesn't like it, it's set to none
in the bios. The machine pulls down backups via smbtar of windows
workstations. The p120 can transfer, and gzip -1 faster than what
Windows on a Celeron 1000 can spit out on the network. It's not until I
go to Pentium 4/2.4's or Celeron 1800's on Windows PC's that it exceeds
the p120's capacity. Have been replacing the p120's as they fail with
new machines.
With the P4/2.4 servers, I have a pair of gzip -9 sessions going, and we
see about 5-6 meg a second.
As far as cpu load on the machine just transfering files, I'd have to go
with not really noticeable. If you copy a multi gig file around, the
filesystem will take a couple seconds to return an ls, but cpu load is
low, just sitting waiting for IO, which jams up anything else happening.
They're dedicated machines, so as long as it can pull the image and gzip
on the fly, I'm happy.
They work nicely except for:
<rant>
Travan(8/14/20 gig) drives die after a year or so
DDS-3 die after about 3
DDS-4 seems to be better than above
