Applications
The SSC100 is ideal for remote monitoring and
control applications such as FC-AL storage enclosure
management. The SSC100 may be used to
implement a complete SCSI Enclosure Services
(SES) or SAF-TE solution in Fibre Channel JBODs,
RAID subsystems and servers. The embedded
firmware capabilities of the SSC100 allow storage
system architects to differentiate their products via
firmware. Software Development Kit (SDK) is
provided by Vitesse to accelerate the development of
firmware Personality Modules. Multiple SSC100s
may be used in fully redundant, dual loop
applications with the use of a flexible heartbeat
mechanism.
Architecture
System Level Integration (SLI) techniques were used
to create a complete system on a chip. The SSC100
integrates a RISC embedded processor, high
performance Fibre Channel protocol engine, a
gigahertz transceiver and memory to create an
embedded system for enclosure management.
The SSC100 includes three, I
2
C serial interface bus
master controllers. These controllers may be used to
interface to off-the-shelf instrumentation and control
devices commonly used in environmental monitoring
and management applications such as Vitesse's
SSC050/055 Backplane Controller.
The SSC100 requires off chip memory for firmware
code storage. Most applications will use flash
memory devices for non-volatile storage. Static RAM
may be added for higher performance applications.
The SSC100 has four external chip selects each with
a one-megabyte address range.
Two RS-232 serial ports provide assist firmware
debug. One port is dedicated to in circuit emulation
for the embedded processor. The second port
implements a XMODEM connection for additional
debug and firmware download. Firmware downloads
are also supported via Fibre Channel.
Software
The software designed to execute on the SSC100
determines the characteristics of the overall
enclosure management solution. Most enclosure
management applications will be unique to a
customer's individual product. The SSC100 firmware
architecture uses a Personality Module with captures
the unique functionality required by a particular
application.

Software
The SDK includes software to implement a FC
transport and SES diagnostic environment. In
addition, the SDK also includes a System Services
module with provides APIs to the peripheral
functionality (interrupts, timers etc.) in the SSC100.
The System Services also includes driver libraries for
popular I
