Hi Robert,

we are using OX commercial version on a FSC server (Primergy series).

Short to our history:
We started june 2003 (with SLOX 4) with only 512 MB RAM but dual
motherboard with 2 x XEON 1.8 GHz and 3 x 36 GB HD 10K rpm as RAID-5
(SCSI). We decided to use ONLY SCSI-drives in all our server cause all of
them running 24 hours a day and 7 days a week - minimum 5 years. We are
satisfied with that strategy cause we only have few hardware errors a year
(and it doesn´t matter if a hd fails in a RAID-system).

As we startet with 25 user the system performance was ok. With 50 user the
system began to swap and as we reached 75 user I decided to upgrade the
system up to 2.5 GB. Now we have nearly 100 User and an average
mail-traffic of 1.2 GB +/- 100 MB a month (for all of our user) and system
is NOT swapping. We are using the complete groupware accept the forum.

So I would prefer the first option (2 GB RAM & SCSI HDs) but only with
redundant CPU, power and RAID-1 or RAID-5 hd system ...

Kind regards
