monitoring and management applications such as
Vitesse VSC055/050 Backplane Controllers.
The VSC205 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 VSC205 has three 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
downloads are also supported via the SCSI bus.
download.
Firmware
Software
The software designed to execute on the VSC205
determines the characteristics of the overall
enclosure management solution. Most enclosure
management applications will be unique to a
customer's individual product. The VSC205
firmware architecture uses a Personality Module with
captures the unique functionality required by a
particular application. Vitesse provides a Software
Development Kit (SDK) to customers to assist their
development of their Personality Module.
The SDK includes software to implement an ESI and
a parallel SCSI transport for SAF-TE or SES
diagnostic environments. In addition, the SDK also
includes a System Services module with provides
APIs to the peripheral functionality (interrupts, timers
etc.) in the VSC205.
The VSC205 shares a similar hardware and
firmware architecture as Vitesse SSC200 and
SSC100. This allows system designers to leverage
enclosure
management
implementations across parallel SCSI, ESI and
dedicated port FC-AL storage solutions.
