Sun Microsystems 2500 manual SFP Transceivers

■Two data host connectors per controller that can support either a fiber-optic interface or a copper interface with 1, 2, or 4 Gb/s data host connection speed

■One drive expansion tray Serial Attached SCSI (SAS) connector with 3 Gb/s drive expansion tray connection speed

■512-MB or 1-GB mirrored cache

■Maximum connection of 36 disk drives (one controller tray and two drive expansion trays)

When fiber-optic cables are used to connect to the data host, a Small Form-factor Pluggable (SFP) transceiver is required to make the connection.

SFP Transceivers

You can connect the Sun StorageTek 2540 Array to either copper host interface cables or fiber-optic host interface cables. If you use fiber-optic cables, you must install an SFP transceiver in each interface connector on the controller where a fiber-optic cable is to be installed. The SFP transceiver is required to translate the optical signals from the fiber-optic cable into digital signals for the controller.

Note – The SFP transceiver shown might look different from those that are shipped with your controller tray. The difference does not affect transceiver performance.
