Hi, excuse my domain of the english.
 
 
- With Windows, everything is OK. Filer CPU is <10% workload.
 
OK
 
- LUN Space reserve is disabled. Does it have any impact on performance?
 
This choice are important. If LUN Space reserve is disabled, the performance in the LUN can be impacted. NetApp recommends enable this option in order to obtain best performance. Enable this option, wait any hours ans test the performance in Novell.
 
- We use 2 NICs in the Novell Server, one NIC to LAN and the other for iSCSI to the NetApp.
 
OK
 
- Our CPU workload is >20% on the Novell Server
 
OK
 
- No iSCSI HBA exists with Novell driver
 
OK, the workload in the CPU is low.
 
 
Please, review the performance in other protocols over the same volume. As CIFS or NFS to obtaint the  cause of the problem.
 
Yo can try obtain IOmeter software from Intel Website to test performance in Linux, Solaris, Windows and Netware. Iometer can be used to test NICs and Storage performance.

You need have two test later.
 
 
1. Test iSCSI configuration with other machines. (for Example: In you PC Windows XP or other Windows Servers)
2. Enable the "LUN Space reserve in ontap"
 
If your problem continue in Windows...mmm, you need verify the number of spindles(Disk in the same RAID group) in the Filer.
 
If you don´t have proble in Windows and the Space Reseve are enable. Test with two NICs in the Novell Server. One NIC to the LAN and Clients and one or more NICs to the iSCSI.
 
The iSCSI software in Novell pack the data with the CPU, if you have workload on the CPU (20% or more), iSCSI runs slow. Try using iSCSI HBA.

Asunto: Netapp & Novell Netware over iSCSI

Hi

 

Does somebody have experiences with connecting NetApp to Novell Netware over iSCSI? We have problems with throughput (only 2-3 Mbps): A lot of network-retransmits and tcp-window errors on the Novell side.

Network cable and adapter is ok.

 

Environment:

- NetApp FAS3020

- Netware 4-Node Cluster

- Netware 6.5 SP2 and SP4

- Groupwise 6.5

- Novell software initiator 1.03 and 1.04

- Intel Pro/1000 Ethernet Adapter

- Point-to-Point Network connection from filer to the server without an ethernet switch

 

Best regards

Marcel
