Abstract:
1. A platform for computer processing, connectable to an external communication network and a storage network and comprising: a plurality of computer processors connected to an internal communication network; configuration logic to define and establish (a) a virtual local area communication network over the internal network, wherein each computer processor in the virtual local area communication network has a corresponding virtual MAC address and the virtual local area network provides communication among a set of computer processors but excludes the processors from the plurality not in the defined set, and (b) a virtual storage space with a defined correspondence to the address space of the storage network; and failover logic, responsive to a failure of a computer processor, to allocate a computer processor from the plurality to replace the failed processor, the failover logic including logic to assign the virtual MAC address of the failed processor to the processor that replaces the failed processor, logic to assign the virtual storage space and defined correspondence of the failed processor to the processor that replaces the failed processor, and logic to reestablish the virtual local area network to include the processor that replaces the failed processor and to exclude the failed processor.
