ABSTRACT:
An existing disk drive storage enclosure is converted into a standalone network storage system by removing one or more input/output (I/O) modules from the enclosure and installing in place thereof one or more server modules (“heads”), each implemented on a single circuit board. Each head contains the electronics, firmware and software along with built-in I/O connections to allow the disks in the enclosure to be used as a Network-Attached file Server (NAS) or a Storage Area Network (SAN) storage device. An end user can also remove the built-in head and replace it with a standard I/O module to convert the enclosure back into a standard disk drive storage enclosure. Two internal heads can communicate over a passive backplane in the enclosure to provide full cluster failover (CFO) capability.
