VSC205
LVD SCSI Enclosure
Management Controller
Product Brief
Overview
The VSC205 is an enclosure management controller
for peripheral storage applications. This device
supports in-band and out of band management
strategies. The VSC205 implements in-band SES
and SAF-TE enclosure management via the
integrated SCSI interface. Out of band solutions
are possible using IPMI (Intelligent Platform
Management Interface) or through a customer
unique approach.
JBOD and RAID subsystem developers are provided
a common hardware and software platform, which
supports all common subsystem diagnostic and
enclosure management strategies. The VSC205
may be used as the master controller of a I

SCSI Applications
The VSC205 offers dedicated port enclosure
management across a parallel SCSI bus. The
VSC205’s integrated LVD SCSI controller is used to
provide a high performance, SES or SAF-TE
solution. No external components are required with
this approach; the VSC205 integrates both the data
and command buffers and control logic. This
architecture provides system designers with a
common platform for various SCSI bus speeds and
physical interfaces.
Architecture
System Level Integration (SLI) techniques were
used to create a complete system on a chip. The
VSC205 integrates a RISC embedded processor
and additional DMA, memory and controller
functionality.
The VSC205 includes three, I

master controllers. These controllers may be used
to interface to off-the-shelf instrumentation and
control devices commonly used in environmental
