 Ive got XFS on a 'production' file server. The machine could have upto
500 people logged in, but typically less than 200. Most are Mac users,
connected via NetAtalk for 'personal files', although there are shared
areas for admin units. Probably about 30-40 windows users. (Samba)
 Its the file server for an Academic faculty at a University. We have a
AlphaServer 800 running Digital Unix for email and web (running ADVFS,
Digital/Compaq/HP?'s journaling FS). Also a old mac G3 'server' running
ASIP 6.3


bash-2.04$ df -h -T

(The user count is wrong - Im trying to use Samba's UTMP support, and it
often doesn't clean up after itself :-)
bash-2.04$ ps -ef | grep afpd | wc

 Might give a better idea of current 'users' - just under 150.

uname -a
Linux aristotle.arts.usyd.edu.au 2.4.7-pre6-xfs #24 SMP Thu Jul 19
16:47:10 EST 2001 i686 unknown
bash-2.04$ 

 Hardware RAID, via Mylex dual channel controller with 4 drives, Intel
Tupelo MB, Intel 'SC5000' server chassis with redundant power and
hot-swap scsi bays. The system boots of a non RAID single 9gb UW-scsi
drive.

 Have removed both a power supply and a raid disk on the running system
to check that the redundancy actually worked (and that scripts watching
for faults actually worked...) 

 Only system 'crash' was caused by some one accidently unplugging it,
just before we put it into production. In day to day use it has run
well.

 The network between the users is Cisco ethernet switches, at 100Mb,
with 1000Mb optical trunks and 7 'virtual' LANs.
