An information processing module includes a processor subsystem including a processor and memory. The information processing module is configured as a field replaceable unit blade server removably receivable in a carrier. Redundant external connections are provided for interconnection with the carrier. The external connections for carry information signals, management signals and power. The information processing module can be configured as a field replaceable blade server. The provision of a limited set of redundant connections provides for highly reliable interconnection between the information processing module and the carrier.

Interfacing computer modules

Systems and methods ('utility') for providing a computer system with a mechanism to record live data on a continuous basis which may be analyzed subsequent to a fault condition is provided. The utility uses the existing DRAM memory of a computer system as a retentive DRAM (RDRAM) device that may be used to store the data. To accomplish this, software and firmware is provided for continuously refreshing the DRAM memory across resets that are due to fault conditions. Further, non-maskable interrupts (NMI) are used to flag a variety of fault conditions to the computer system. To make the utility platform independent, a standardized power and configuration interface is used to implement a computer system reset that preserves the contents of the RDRAM.

A server blade is provided which comprises a processor. The server blade additionally comprises an enclosure which encloses the processor. The server blade is configured as a field replaceable unit removably receivable in a carrier of a modular computer system, and is configured as an oversized unit to span more than one standard information processing module receiving location in the carrier.

Extended computing system

An information processing module, for example a server blade, has information connections and storage connections. A carrier, e.g., a rack mountable shelf, is configured to receive a number of information processing modules. A switch module is operable to connect a received information processing module to an external information network. The switch includes an external storage connection operable under an external storage channel format, e.g., Fiber Channel. A protocol converter converts between information packets comprising packet format storage data (e.g., iSCSI format) received from an information processing module and signals in the external storage channel format. Redundant connections are included to enhance reliability.

External storage for modular computer systems

A support module for a modular computer system can provide switching functions. Internal information signal interfaces can connect to information processing modules. First external information interfaces can connect to a first external information network under a first network protocol different to a network protocol used internally to the support module. A connector sub-module, receivable in the support module, includes a protocol translator for translating between information protocols.

Computer system storage

A modular computer system (e.g., a server blade system) includes a carrier (e.g., a rack mountable shelf) carrying a plurality of removably mountable information processing modules (e.g., server blades). Each information processing module can include a processor operable to provide information processing functions and a service controller operable to provide monitoring and system management functions. The carrier and the information processing modules can be interconnected by separate information and service management paths so that system management signals can be communicated independently of information signals. A combined switch and service processor module can be provided in the carrier. The switch and the service processor can be interconnected via a communications link for controlled information passage between a management network and the information processing modules via an information path.

An information distribution module may be provided removably received in the carrier operable connect to the internal communications network to receive an information message, to perform processing on the message to determine a destination, and to forward the message toward the determined destination via the internal communications network.

Server blade for performing load balancing functions

A rack mountable shelf is configured to support a plurality of field replaceable units in the form of server cartridges that each include at least one server processor. The rack mountable shelf is configured to provide communal services for said server cartridges, including at least one of supplying DC operating power to the server cartridges, distributing information signals between the server cartridges and processing system management signals for the server cartridges. Each of the server cartridges can be slideably received in a respective one of a series of server cartridge receiving locations arrayed side by side along the front of the shelf. The server cartridges can be configured as thin blades to provide a high server density. For example, 16 server cartridge receiving locations can be provided across the front of the shelf. The supply of DC operating power to the server cartridges can be provided by one or more field replaceable power supply units (e.g. two redundantly configured power supply units) mounted in the shelf. The distribution of information signals between the server cartridges can be provided by one or more switch units (e.g. two redundantly configured switch units) mounted in shelf. The processing of system management signals for the information processing modules is provided by one or more field replaceable service processor units (e.g. one service processor unit) mounted in the shelf. Each of the power supply, switch and service processor units can be slideably received in a respective receiving location at the rear of the shelf.

A multiple computer server can be formed from at least one rack mountable shelf as set out above.

Computer systems

A server blade may comprise a processor. The server blade may additionally comprise a removable media interface device. The server blade can be configured as a field replaceable unit.

Removable media

A processing unit is connectable to a communications network. The processing unit has a data carrier reader operable to read a network identity from a portable data carrier. The processing unit is operable on being powered up to check for the presence of a said data carrier, and when a data carrier is present to use the network identity from the data carrier for communicating via the network. The data carrier can be in the form of a card having readable storage, for example a portable storage device having a readable semiconductor memory of a type know, for example, as a smart card, or memory card. The processing unit may be arranged to use only the network address read from the data carrier, and, in the absence of such a data carrier to prevent access to the network. Access to the network can be achieved by aborting the power up of the processing unit. The processing unit may therefore access the network only when the network address is present in the carrier reader when the processing unit is powered up.
