Table 190 MP Router iSCSI configuration rules Rule Maximum number of iSCSI ports per MP Router Maximum number of TCP sessions per MP Router Number of TCP sessions per port Maximum number of targets per host Maximum 12 96 8 1 The Windows iSCSI Initiator software currently supports a maximum of one target per host when that target is accessed through the MP Router in iSCSI mode. This prevents the use of multipath software. C-series iSCSI The C-series IP Storage Services Modules, 14/2 Multiprotocol Services Module, 18/4 Multiservice Module, MDS 9216i Multilayer Fabric switch, and MDS 9222i Multiservice Fabric switch provide iSCSI capabilities. These devices allow IP hosts to access Fibre Channel storage using iSCSI. The IP Storage Services Modules, 14/2 Multiprotocol Services Module, 18/4 Multiservice Module, 9216i switch, and MDS 9222i Multiservice Fabric switch provide transparent iSCSI routing by default. IP hosts using iSCSI can access targets on the Fibre Channel network. This section describes the following topics: • Modules overview, page 384 • Hardware support, page 385 • Software support, page 387 • Configuration rules, page 388 For the latest C-series documentation, see http://h18006.www1.hp.com/storage/saninfrastructure.html. Modules overview The C-series IP Storage Services Modules (IPS-4, IPS-8), 14/2 Multiprotocol Services Module, 18/4 Multiservice Module, 9216i switch, and MDS 9222i Multiservice Fabric switch provide IP hosts access to Fibre Channel storage systems. The IP host sends SCSI commands encapsulated in iSCSI PDUs to a module port over a TCP/IP connection. These commands are routed from the IP network to the Fibre Channel network and then forwarded to the target. Figure 143 shows a sample configuration where an IP module bridges an IP network and a Fibre Channel network. 384 iSCSI storage
