The MPS-14/2 module is available for use in any switch in the Cisco MDS 9200 Series or Cisco MDS 9500 Series. • The iSCSI feature is not supported on the Cisco Fabric Switch for HP c-Class Bladesystem and Cisco Fabric Switch for IBM BladeCenter. iSCSI Restrictions iSCSI has the following limits in Cisco SAN-OS Release 3.0(1) and later: • Maximum iSCSI sessions on a switch -5000 • Maximum iSCSI sessions per IPS port (not proxy initiator mode) -500 • Maximum iSCSI sessions per IPS port (proxy initiator mode)-500 • Maximum concurrent iSCSI session creations per port-5 If more ISCSI sessions try to come up simultaneously on a port, the initiator gets a temporary error and then the initiator retries. • if iSLB CFS is enabled, you must use Device Manager to commit any iSCSI global configuration changes made through Fabric Manager. iSLB Restrictions iSLB has the following restrictions in Cisco SAN-OS Release 3.0(1) and later: • Maximum iSLB initiators in a physical fabric-2000. • Maximum number of iSCSI sessions per IPS port in either transparent or proxy initiator mode-500. • • Maximum number of switches in a fabric that can have iSLB with CFS enabled-4. • iSLB can be used without CFS distribution but if iSLB auto-zone feature is used, traffic disruption occurs when any zone set is activated. • Maximum number of initiators in the pending configuration- 200. Before adding more initiators, you must commit the configuration first. 20-2 Cisco MDS 9000 Family Troubleshooting Guide, Release 3.x OL-9285-05

Cisco MDS 9000 Family Troubleshooting Guide, Release 3.x
OL-9285-05
Chapter 20
Troubleshooting IP Storage Services
Overview
Figure 20-1
Connecting MDS 9000 Family Switches Over IP
Note
The iSCSI feature is specific to the IPS module and is available in Cisco MDS 9200 Switches or
Cisco MDS 9500 Directors.
The Cisco MDS 9216i switch and the 14/2 Multiprotocol Services (MPS-14/2) module also allow
you to use Fibre Channel, FCIP, and iSCSI features. The MPS-14/2 module is available for use in
any switch in the Cisco MDS 9200 Series or Cisco MDS 9500 Series.
The iSCSI feature is not supported on the Cisco Fabric Switch for HP c-Class Bladesystem and
Cisco Fabric Switch for IBM BladeCenter.
iSCSI Restrictions
iSCSI has the following limits in Cisco SAN-OS Release 3.0(1) and later:
Maximum iSCSI sessions on a switch —5000
Maximum iSCSI sessions per IPS port (not proxy initiator mode) —500
Maximum iSCSI sessions per IPS port (proxy initiator mode)—500
Maximum concurrent iSCSI session creations per port—5
If more ISCSI sessions try to come up simultaneously on a port, the initiator gets a temporary error
and then the initiator retries.
if iSLB CFS is enabled, you must use Device Manager to commit any iSCSI global configuration
changes made through Fabric Manager.
iSLB Restrictions
iSLB has the following restrictions in Cisco SAN-OS Release 3.0(1) and later:
Maximum iSLB initiators in a physical fabric—2000.
Maximum number of iSCSI sessions per IPS port in either transparent or proxy initiator mode—500.
Maximum number of switches in a fabric that can have iSLB with CFS enabled—4.
iSLB can be used without CFS distribution but if iSLB auto-zone feature is used, traffic disruption
occurs when any zone set is activated.
Maximum number of initiators in the pending configuration— 200. Before adding more initiators,
you must commit the configuration first.
