    Abstract: Embodiments of the present invention include a storage-shelf-router-to-disk-drive interconnection method within a high-availability storage shelf amenable to dynamic reorganization in order to ameliorate error conditions that arise within the high-availability storage shelf. In one embodiment, each path-controller card (PC1-PC16) within the storage shelf is interconnected to two storage-shelf routers (128, 13, 132, 134) on separate storage-shelf-router cards via two serial management links and two serial data links. Different types of errors that may arise within the storage shelf are carefully classified with respect to a number of different error-handling techniques, including local path failovers, single path failovers, error reporting and logging, and other types of error handling techniques. In many implementations, particular error handling methods are configurably associated with particular errors, in order to adept error behavior in a storage shelf to the needs and requirements of a system that includes the storage shelf. Additional embodiments of the present invention concern detection and diagnosis of errors, in addition to handling errors that arise within a storage shelf.

    Abstract: An integrated circuit implementing a storage-shelf router (1018) used along, or in combination with other storage-shelf routers (1014), and in combination with path controller cards, to interconnect the disks (1022-1025) within a storage shelf or disk array to a high-bandwidth communications medium through which data is exchanged between the individual disk drives or the storage shelf (1100) and a disk-array controller (1006). In various embodiments, the present invention provides virtual disk formatting by a storage shelf router (1018) and the storage shelf (1100) in which the storage-shelf is included, to external computing entities, such as disk-array controllers (1006) and host computers (1002). By providing virtual disk formatting, a storage-shelf router (1018) can provide to a disk-array controller (1006), and other external computing entities, the disk-formatting convention (4410) expected by the disk-array controller (1006), even though disk drives (1022-1025) and other storage systems that do not conform to the expected formatting conventions may be included in the storage shelf (1100) and interconnected to a disk-array controller (1018) and other external processing entities via an interface provided by a storage-shelf router (1018). Virtual disk formatting, in addition, allows a storage-shelf router to format a disk drive differently from the disk formatting expected by external computing entities, so that the storage-shelf router (1018) can transparently include additional information into disk sectors (4402), such as additional error-correction information.

    Abstract: An integrated circuit implementing a storage-shelf router, used in combination with path controller cards and optionally with other storage-shelf routers, to interconnect SATA disks within a storage shelf or disk array to a high-bandwidth communications medium, such as an FC arbitrated loop. Various embodiments of the present invention provide a tunneling mechanism through the storage-shelf interface provided by one or more storage-shelf routers within a storage shelf to enable external processing entities to directly access various components within the storage shelf. In one embodiment of the present invention, a WRITE-BUFFER command and a READ­BUFFER command are added to the command interface supported by storage-shelf router. These commands are exchanged via the FCP protocol over the fiber channel in the same manner that SCSI commands are packaged within the FCP protocol. In certain cases, the information packaged within the WRITE-BUFFER and READ­ BUFFER commands is directly exchanged with internal disk drives. In other cases, the information is extracted and written to various data structures maintained within internal components of the storage shelf. The WRITE-BUFFER and READ-BUFFER commands essential provide a breach or tunnel in the high-availability storage-shelf virtual interface provided by one or more storage-shelf routers within a storage shelf, allowing an external processing entity to exchange information through the tunnel without intervention by, but facilitated and supported by, the one or more storage-shelf routers within the high-availability storage shelf.

    Abstract: An integrated circuit implementing a storage-shelf router used alone, or in combination with other storage-shelf routers, and in combination with path controller cards, to interconnect the disks within a storage shelf or disk array to a high-bandwidth communications medium, such as an FC arbitrated loop, through which data is exchanged between the individual disk drives of the storage shelf and a disk-array controller. A set of interconnected storage-shelf routers within a storage shelf can be accessed through a single port of an FC arbitrated loop or other high-bandwidth communications medium. Because, in one implementation, eight storage-shelf routers can be interconnected within a storage shelf to provide highly available interconnection of sixty-four disk drives within the storage shelf to an FC arbitrated loop via a single FC-arbitrated-loop port, a single FC arbitrated loop including a disk-array controller, may interconnect 8,000 individual disk drives to the disk-array controller within a disk array. The storage-shelf router can serve to translate FC-based communications protocols into one or more communication protocols appropriate to the internal links, providing for use of less expensive, non-FC-compatible disk drives within the storage shelf.

    Abstract: An integrated circuit implementing a storage-shelf router (1018) used along, or in combination with other storage-shelf routers (1014), and in combination with path controller cards, to interconnect the disks (1022-1025) within a storage shelf or disk array to a high-bandwidth communications medium through which data is exchanged between the individual disk drives or the storage shelf (1100) and a disk-array controller (1006). In various embodiments, the present invention provides virtual disk formatting by a storage shelf router (1018) and the storage shelf (1100) in which the storage-shelf is included, to external computing entities, such as disk-array controllers (1006) and host computers (1002). By providing virtual disk formatting, a storage-shelf router (1018) can provide to a disk-array controller (1006), and other external computing entities, the disk-formatting convention (4410) expected by the disk-array controller (1006), even though disk drives (1022-1025) and other storage systems that do not conform to the expected formatting conventions may be included in the storage shelf (1100) and interconnected to a disk-array controller (1018) and other external processing entities via an interface provided by a storage-shelf router (1018). Virtual disk formatting, in addition, allows a storage-shelf router to format a disk drive differently from the disk formatting expected by external computing entities, so that the storage-shelf router (1018) can transparently include additional information into disk sectors (4402), such as additional error-correction information.
