Abstract

Currently, all entry servers provide some level of environmental and physical intrusion hardware and software to alert an IT manager of a problem on the server. Because of price competition, this solution need to be designed, verified and placed in a low-cost ASIC. However, each time additional function is required or a problem is found, this ASIC must be changed at a high cost to the manufacturer. However, by using an on-chip processor that contains a reprogrammable programming region changes can be made and additional function added in a common design. This low-cost entry solution is expandable and upgradable in the field with no additional cost to the base alerting server function. This disclosure depicts the use of an embedded processor that can be installed on all servers for a very small increase in price to provide a base level of advanced system management function which can later be expanded when the server does a "refresh" or when new software function is added.

Configurable, Modular Service Processor Function

Currently, all entry servers provide some level of environmental and physical intrusion hardware and software to alert an IT manager of a problem on the server. Because of price competition, this solution need to be designed, verified and placed in a low-cost ASIC. However, each time additional function is required or a problem is found, this ASIC must be changed at a high cost to the manufacturer. However, by using an on-chip processor that contains a reprogrammable programming region changes can be made and additional function added in a common design. This low-cost entry solution is expandable and upgradable in the field with no additional cost to the base alerting server function. This disclosure depicts the use of an embedded processor that can be installed on all servers for a very small increase in price to provide a base level of advanced system management function which can later be expanded when the server does a "refresh" or when new software function is added.

  The embedded processor contains its own flash and RAM. Once the requirements for the service processor are known, that function can be implemented and the product shipped with a certain amount of base function. In the figure below, all the hardware fixed functions are software coded in the embedded processor. Additional function can 2be added via the Ethernet or the IC interface without changing the hardware. This is a big improvement over the cur...
