Required Minimum Hardware for E_Port Disk Streaming

A significant performance gain is normally achieved in networks which limit the number of concurrent SCSI I/O operations and in networks with high latency. E_port Disk Streaming is aware of SCSI I/O operations and of the initiator (originator) and target (responder) relationships of the hosts and devices using the SCSI protocol.

ISL Dynamic Load Sharing (DLS) will not work with E_port Disk Streaming. Make sure this feature is disabled on the Fibre Channel switches with multiple ISLs. Configure static ISL routes between end-points where possible.
