We are using Netware 6 SP5 Server running on an HP Proliant ML370 2.8GHz
hardware. We have a Netapp FAS270 storage (SAN) device attached with
volumes being mounted on the local server using ISCSI.

The problem we have is very poor performance with backups (using Arcserve)
and the Netapps device in general. We have been in contact with Netapp and
they think the problem is with the Netware servers.

We did a test backup using a Windows Server and it gave a throughput of
over 1GB/MIN.

On Netware we are getting 100MB/Min. Our suspicion is maybe read speeds
using ISCSI.

Have you got any suggestions to improve the performance please ?
