The Sun StorageTek 2540 Array, the Sun StorageTek 2530 Array, and the Sun
StorageTek 2501 Array are a family of storage products that provide high-capacity,
high-reliability storage in a compact configuration.
The Sun StorageTek 2540 Array is a modular, rackmountable controller tray. It is
scalable from a single dual-controller tray (1x1) configuration to a maximum
configuration of 1x3 with two additional drive expansion trays behind one controller
tray.
All three of the trays can be installed in the following cabinets:
■ Sun Rack 900/1000 cabinet
■ Sun StorageTek Expansion cabinet
■ Any 19-inch wide, 4-post, EIA-compatible rack or cabinet with a front-to-back
depth between vertical cabinet rails of 61 cm to 91 cm (24 in. to 36 in.). The
cabinet can have threaded or unthreaded cabinet rails.
The Sun StorageTek 2540 Array and the Sun StorageTek 2530 Array contain disk
drives for storing data and controllers that provide the interface between a
management and/or data host and the disk drives. The Sun StorageTek 2540 Array
provides a Fibre Channel connection from the data host to the controller. The Sun
StorageTek 2530 Array provides a Serial Attached SCSI (SAS) connection from the
data host to the controller.
The Sun StorageTek 2501 Array drive expansion tray provides additional storage.
You can attach the drive expansion tray to either the Sun StorageTek 2540 Array or
the Sun StorageTek 2530 Array.
