I am hoping someone can help me (maybe like Tim Heywood?) We are running
an IBM DS400 SAN with a Dell 2850 server connected via QLOGIC adapter
(QLA2340). The QLOGIC driver is QL2x00.HAM v6.90.09 March, 17, 2006. The
OS is NetWare 6.5 SP 5 and the volumes are traditional with no sub block
alloc, or compression turned on.

Everything works well except performance is terrible. Compared to other
servers that have direct attached storage the DS400 is twice as slow. Are
there performance tuning recommendations for running NetWare with a
DS400? Any help would be greatly appreciated!!
