General rules for the EVA and EVA4400 iSCSI Connectivity Options
NOTE: The EVA iSCSI Connectivity Option (mpx100) is supported with EVA4100/4400/4400
(embedded switch)/6100/6400/8100/8400 storage systems. The EVA4400 iSCSI Connectivity
Option (mpx100b) is supported with EVA4400 and EVA4400 (embedded switch) storage systems.
Use the following general rules when implementing the EVA or EVA4400 iSCSI Connectivity
Option:
• Each EVA storage system can have a maximum of two mpx100 or two mpx100b bridges.
• Each EVA controller host port can connect to a maximum of two mpx100/100b Fibre Channel
ports.
• Both mpx100/100b Fibre Channel ports can only connect to one EVA storage system.
• Each mpx100/100b Fibre Channel port can only connect to one EVA port.
• Each iSCSI initiator can have a maximum of eight mpx100/100b iSCSI targets.
Table 186 (page 352) describes the maximum number of servers, initiators, and LUNs supported
for combined iSCSI and Fibre Channel connectivity to an EVA configured with an mpx100 or
100b.
