摘要： A volume translation apparatus and method are provided. The volume translation apparatus resides between host machines and the physical storage devices accessed by the host machines. This volume translation apparatus may perform volume translation for the control path and optionally the data path of input/output (I/O) requests sent by the host machines to the physical storage devices. Control path translation ensures that the correct physical volumes are mounted for accessing by the I/O request. Because the physical volume may be different from that requested by the host machine application, the translation device includes a mapping that represents which physical volumes represent copies of the virtual volume used by the host machine application. When an I/O request is received and is directed to a particular original virtual volume, the volume mapping apparatus translates the original virtual volume identification into one or more physical volume identifications associated with a secondary virtual volume which may or may not be the same as the original virtual volume.

摘要： A system for data storage includes a switch node, a meta-data server, a plurality of storage servers having at least one respective data storage device, and a scalable interconnect. The scalable interconnect couples the switch node, the meta-data server, and the storage servers. At least one of the switch node, the meta-data server and the storage servers includes a hierarchical storage manager (HSM). When information is received at the switch node, the HSM presents the information substantially simultaneously to the storage servers for storage at the respective data storage devices.
