For iR16SAEJ, Serial-attached SCSI offers advantages over older parallel

technologies. The cables are thinner, and the connectors are less bulky. Serial

data transfer allows the use of longer cables than parallel data transfer.

There are some applications to connect with iR16SAEJ. Mostly, it is used as the

expansion of RAID subsystem and can be cascaded up to 4 iR16SAEJ. The

expansion port of RAID subsystem connects to IN connector of iR16SAEJ; then

the OUT connector connects to the next iR16SAEJ …etc. Besides, iR16SAEJ

can be connected to host directly. The host will display available disks in disk

manager. Another application is Windows cluster; two hosts connect to IN

connectors of iR16SAEJ.
