    Abstract: An integrated circuit implementing a storage-shelf router (2402, 2403, 2404, 2405) used alone, or in combination with other storage-shelf routers (2402, 2403, 2404, 2405), 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 (2402, 2403, 2404, 2405) 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 (2402, 2403, 2404, 2405) 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 translation: 实现单独使用或与其他存储架子路由器（2402,2403,2404,2405）组合使用的存储架子路由器（2402,2403,2404,2405）的集成电路并且与路径控制器卡组合以进行互连 存储架或磁盘阵列中的磁盘到诸如FC仲裁环路的高带宽通信介质，数据在存储架的各个磁盘驱动器与磁盘阵列控制器之间交换。 可以通过FC仲裁环或其他高带宽通信介质的单个端口来访问存储架内的一组互连存储架子路由器（2402,2403,2404,2405）。 因为在一个实现中，八个存储架路由器（2402,2403,2404,2405）可以在存储架内相互连接，以通过单一的方式将存储架内的六十四个磁盘驱动器的高可用性互连连接到FC仲裁环路 FC仲裁环路端口，包括磁盘阵列控制器的单个FC仲裁环路可以将8,000个单独的磁盘驱动器连接到磁盘阵列中的磁盘阵列控制器。 存储架子路由器可以用于将基于FC的通信协议转换成适合于内部链路的一个或多个通信协议，从而提供在存储架内使用较便宜的非FC兼容磁盘驱动器。
