VSC210 Functional Block Diagram
Applications
The VSC210 is an ideal Baseboard Management
Controller for server management applications. The
VSC210 and related Software Development Kit (SDK)
implement the IPMI 1.0 specification for BMCs. The
VSC210 may also be used in applications other than
IPMI through firmware modifications.
Architecture
System Level Integration (SLI) techniques were used to
create a complete system on a chip. The VSC210 is
based on Vitesse’s proven architecture for enclosure
and platform management solutions. It integrates an
embedded RISC processor, a flexible system interface,
memory and multiple peripheral interfaces to create an
embedded system for server platform management.
The VSC210 includes three, I²C multi-master bus
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 controllers also
support direct connection to Intelligent Platform
Management Buses (IPMB).
The VSC210 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
VSC210 has four external chip selects each with a one-
megabyte address range.
The VSC210 integrates three UARTs. One port may be
used as a firmware debug port. A second port fully
implements the Intelligent Chassis Management Bus
(ICMB) defined by IPMI. A third, general purpose UART
is provided for maximum system design flexibility. The
Vitesse provided Software Development Kit includes
ROM Monitor and firmware download functionality via
the UARTs.
Software
The software designed to execute on the VSC210
determines the characteristics of the overall server
management solution. Most server management
applications will be unique to a customer's individual
product. The VSC210 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 KCS and
System Management Interface Chip (SMIC) transport
and IPMI diagnostic environment. In addition, the SDK
also includes a System Services module with provides
APIs to the peripheral functionality (interrupts, timers
etc.) in the VSC210. The System Services also includes
driver libraries for popular I²C devices such as National's
LM75, LM78, and many others.
