摘要
A system, method and program product that utilizes a hybrid fault tolerance system for managing data. A system is disclosed that includes: a system for partitioning memory into a set of partitions that includes a designated partition for storing immutable objects; a write system for storing an immutable object in the designated partition, wherein the immutable object is coded with a hardware-based fault tolerance system to generate a set of hardware-based codewords, and wherein the immutable object is further coded with a software-based fault tolerance system to generate a set of software-based codewords; a read system for retrieving the immutable object, wherein the read system decodes each hardware-based codeword for the immutable object, and in response to a failed decoding of a hardware-based codeword, the read system decodes the software-based codeword containing a failed hardware-based codeword.
