Netware 5.0 slows down with large file copy
Posted on 2001-08-03
I have an automatic 2gb (3 files) backup process occur on a NT 4 server to the Novell server. When this process occurs all access to the Novell server slows down to the point where a response can take several minutes or a 'server unavailable' warning is displayed. Logging either does not work or it takes a very long time.
Meanwhile, server utilization is averaging at around 42% during this copy process (console response time is fairly slow). Oddly enough, the NT copy process seems unaffected and continues for about 1/2 hour (~ 70Mb/min - slow for 100mbs but about average for this environment - perhaps a bonus question??).
This slowdown is not limited to this specific example rather it's the most extreme example. Whenever anyone runs a large copy process to the Novell server, it is experienced by everyone (clients use the Novell client). Only the Novell server seems to experience this problem....NT server tests do not behave this way. Can't be a Novell issue, huh? I'm convinced this is a correctable configuration issue!
Novell server: 5.0 SP6a, PII 350, 512MB, 4 x 18gb SCSI RAID 5 DPI RAID IV, Intel server NIC. IPX only
NT 4 SP3 servers: PII300, 256MB, 3x8gb SCSI RAID 5 (COMPAQ) - IP/IPX
Clients: Win 9x, NT, 2000 all with latest clients and SP3 all using IPX only for Novell Client and IP for NT/Internet
HP Procurve 4000M switch 10/100
Help me fix this soon.... and I'll give you bonus points!
