Abstract
In a high-performance data storage system, an enclosure contains a multiplicity of disk drives, each of which has two high-speed serial data ports. Respective data lines are provided which connect each of the data ports with a respective high-speed data multiplexer. Importantly, each of the multiplexers is also connected with each of two distinct I/O modules. Failure of either I/O module still permits the remaining I/O module to have serial high-speed connectivity with each of the multiplexers, and thus with each of the data ports on each disk drive. Finally, the overall function of the system may be selected as JBOD (Just a Bunch Of Drives), as SAN (Storage Area Network), or NAS (Network Attached Storage), without requiring any mechanical or electronic change other than the I/O modules.
