NEC Corp has announced the European release of its first fault-tolerant Linux server, the Express5800/320La, which has been developed in conjunction with fault tolerant server specialist Stratus Technologies Inc.
Tokyo, Japan-based NEC's two-way Intel Corp processor-based dual redundancy server uses the same hardware architecture as Stratus's ftServer and its own Express5800 Windows fault-tolerant servers. The architecture enables all processing and I/O commands to run on redundant components in lockstep with fault-tolerant failover in the case of module failure.
The product's Linux operating system is based on Red Hat Inc's Linux 7.1 but features "significant changes" to the kernel, device drivers, storage management and memory management to enable it to support the fault tolerant features. NEC's UK business development director, Paul Evans, stated that the modifications made to the Linux operating system would be released to the open source community via NEC's involvement in the OSDL Open Source Development Lab.
