Along the NetWare support lines, we are hoping that iSCSI will provide the support we need for Novell. From what we understand the NetWare iSCSI initiator will ship in the NetWare 6.5 box in June.
Any thoughts?

Robert,
One problem is that in workgroup mode NTFS security isn't available. In fact, no real security is available...
There appear to be two options to using a filer in a Novell environment:
1) The "gateway" Novell server approach. This involves using a Novell server running Novell NFS Services (with lots of CPU and RAM) with a direct back-to-back link to the filer to act as an I/O path. Clients and application hosts only see the Novell server, while the filer thinks the Novell server is a Unix NIS server that also happens to be it's only client :o). Security is a subset of Novell permissions as available by mapping Unix permissions. The drawback here is that the Novell server itself will be an I/O bottleneck.
2) eDirectory and Windows integration. For this you need a DC, as you have identified. The Windows DC runs the Novell eDirectory client and the security is synchronised with Novell Account Manager. All clients that need to access the filer need to have the CIFS redirector running. Permissions are mapped by Novell Account Manager.
An issue with approach 2 is that when passwords are changed by a helpdesk directly in eDirectory, they may not be synchronised immediately. If anyone has found a workaround for this please respond.
regards,
Alan.

Does anybody run CIFS shares in workgroup mode? That is not booted/authenticated with a PDC?
I have the joy of trying to make my machine work in a Novell environment
and no DC and would love to share ideas with other lucky souls like me....
TIA

Mark, iSCSI from Novell to NetApp should work just fine if you are only interested in presenting virtual disk Luns and not the NetApp filesystem. In this mode the Novell server will treat the connection like any other hard disk or disk array connection. You still will get many of DataOnTaps great features but at the level of NetApp filers presenting virtual disks/Luns.
Functionally, you could do the same thing with a Fibre Channel interface between the Novell server and the "front" of a filer This could be accomplished if NetApp wrote some HBA drivers for Novell. Don't hold your breath.
iSCSI "theoretically" solves many of these Fibre Channel issues by using your existing network infrastructure and working with more open drivers that supplied by each vendor of each end device. Novell writes Novell and NetApp writes only NetApp.
The ideal environment for iSCSI is any environment that works well on a tranaction basis across a network. This implies latency tolerance. Unlike direct SCSI or FC/SCSI interfaces which have highly deterministic operating charactistics iSCSI hasn't yet achieved those characteristics, i.e. link failover timing issues, etc.
Buy some cards on both ends and try it out in a controlled environment when all the pieces are out.
Good luck, Hunter ----- Original Message ----- From: Mark McGilvray To: toasters@mathworks.com Sent: Wednesday, April 16, 2003 6:25 AM Subject: RE: CIFS in Workgroup mode
