Network Design Criteria

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.
Required Minimum Hardware for E_Port Disk Streaming
For miminum hardware levels for E_port Disk Streaming, see the
“Hardware Requirements for E_Port Disk Streaming” section in the
UltraNet Edge Storage Router - 3000 Series Release Notes.
