ABSTRACT:
A computer system includes a plurality of field replaceable units, each having volatile memory and at least one CPU. The FRUs communicate with each other via centralized logic. A RAID data fault tolerance technique is applied to the system so that an FRU can be lost or removed without loss of its data. An exclusive OR engine is included in the centralized logic or distributed among the FRUs. The RAID logic can restripe itself upon removal or addition of a FRU.
