The SureStore E SCSI Bridge FC 4/2 (SSB) is a customer-installable peripheral that allows an FC host to use FC technology to transmit data to SCSI-based peripherals. In addition to faster transfer data, the SSB enables greater flexibility in the design of data centers. With the SSB customers can extend the distance between a host and peripherals and expand the number of SCSI devices connected to the host. The SSB multiplexes the inputs and outputs from a single FC connection to as many as 4 SCSI buses. Because each bus supports 15 devices, one SSB can support up to 60 devices.
