Novell NetWare 6.5 Support Pack 8
After upgrading to NetWare 6.5 SP8, the server experience very pour performance when accessing the falconstor iSCSI target. The iscsi report output reported the error "UNSUPPORTED_INTERFACE_TYPE". Applying post SP8 iSCSI patches and adjusting the "connection queue depth" parameter as per TID 7004527did not resolve the issue.
Apply the SP7 release of the iSCSI modules to the SP8 server and performance returns to it's previous level.
