SSC200
Enclosure Management
Controller
Product Brief
Overview
Device Features
The SSC200 is an enclosure management controller
for peripheral storage applications. This device
supports several in-band and out of band
management strategies. The SSC200 can
implement in band SES and SAF-TE enclosure
management on parallel SCSI and Fibre Channel.
Out of band solutions are possible using IPMI or
customer unique approaches.

SCSI Applications
Fans
The SSC200 supports two mechanisms for
dedicated port enclosure management across a
parallel SCSI bus. An external SCSI controller can
be connected to the SSC200’s DMA interface to
provide a high performance, two-device SES or
SAF-TE solution. No external components are
required with this approach; the SSC200 integrates
both the DMA buffers and control logic. This
architecture provides system designers with a
common platform for various SCSI bus speeds and
