摘要： A very large virtual volume (e.g., in excess of 500 GB) is formed by distributing the disks in eleven, six-disk RAID-5 sets across the six busses of a primary local back-end controller. A spare disk is provided on each of the six busses. Each RAID-5 set is protected from the failure of a single disk by the spare disks on the busses, which can use the parity data stored in a RAID-5 set to rebuild the data stored on a failing disk and thereby restore redundancy to the RAID-5 set. Each RAID-5 set is also protected from the failure of a bus by the parity inherent in RAID-5. The RAID-5 sets are striped by a front-end controller connected to the primary local back-end controller, and the striped RAID-5 sets are presented to a host computer as a very large virtual volume. If the individual disks are 9.1 GB in size, the size of the very large virtual volume can reach 500.5 GB. If desired, additional groups of eleven, six-disk RAID-5 sets can be formed on additional back-end controllers for purposes of redundancy, cloning (which generates a copy of the data that can be used for off-line backup without interrupting read/write activities on the virtual volume), and disaster tolerance through remote storage. These additional groups of RAID-5 sets along with the RAID-5 sets from the primary local back-end controller, can be formed into mirror sets by the front-end controller, which then stripes the mirror sets and presents the striped mirror sets to the host computer as the very large virtual volume.
摘要翻译：通过在主本地后端控制器的六个总线上的十一个六磁盘RAID-5组中分配磁盘来形成非常大的虚拟卷（例如，超过500GB）。六个总线中的每一个都提供备用磁盘。每个RAID-5集合都受到总线上备用磁盘的单个磁盘故障的保护，可以使用存储在RAID-5集中的奇偶校验数据来重建存储在故障磁盘上的数据，从而将冗余恢复到 RAID-5设置。每个RAID-5集合也可以通过RAID-5固有的奇偶校验来保护总线故障。 RAID-5组由连接到本地后端主控制器的前端控制器进行条带化，条带化的RAID-5集作为一个非常大的虚拟卷呈现给主机。如果单个磁盘的大小为9.1 GB，则非常大的虚拟卷的大小可以达到500.5 GB。如果需要，可以在额外的后端控制器上形成额外的十一个六磁盘RAID-5组，用于冗余，克隆（其生成可用于离线备份而不中断读取的数据的副本 /在虚拟卷上编写活动），以及通过远程存储进行容灾。这些附加的RAID-5组与主要本地后端控制器的RAID-5组可以由前端控制器形成为镜像集，然后将镜像集条纹化并将条带镜集显示为主机作为非常大的虚拟卷。

摘要： A memory mapping system for use by a port adapter in a computer facilitates access to named data buffers in host memory. The system generally comprises a mechanism that enables the adapter to efficiently translate the data buffer name to physical address locations in host memory without knowledge of the memory management policies of the computer. Specifically, the system includes various data structures and pointers that allow the port adapter to view host memory in "port pages" when accessing memory locations of a named data buffer. The data locations are virtually, but not physically, contiguous and the invention provides efficient identification of the physical addresses of the locations.

摘要： A computer interconnect system uses packet data transmission over serial links connecting nodes of a network. The serial links may provide simultaneous dual paths for transmit/receive. An adapter couples a CPU or the like at a node to the serial link. The adapter includes a packet memory for temporarily storing transmit packets and receive packets, along with a port processor for executing the protocol. Packets of data are transferred between the system bus of the CPU and the packet memory by a pair of data movers, one for read and one for write. All of the serial links of the system are connected to a distribution hub which forwards a transmitted packet to a destination node based upon an address sent with the packet. If the path to the destination node is busy, the hub returns a "flow control" signal to the source node, and in response to this signal the transmitted packet is aborted so that time on the network is not wasted by needless transmission that must be discarded.

摘要： A multi-cabinet mass storage system with unified management features. The system includes a first reporting group and a second reporting group each having enclosure with processors, such as an environmental monitoring units (EMUs), for generating and transmitting environmental messages pertaining to the particular enclosures. The enclosures are positioned on shelves within cabinets. A bus or cabinet cable links each enclosure to facilitate broadcasting the environmental messages. The environmental messages identify the sending device's reporting group and its physical location within the system. Additional enclosures are included in this reporting group with enclosures of each reporting group located all in one cabinet, in two or more cabinets, and each cabinet may house one, two, or more reporting groups. A network links all of the cabinets to concurrently broadcast the environmental messages throughout the system and allows enclosures in a single reporting group to be positioned in differing cabinets.

摘要： A dual addressing arrangement comprises a complex address pointer within entries of a communication queue used by a port driver and an port adapter when exchanging information in a host computer. The complex address pointer comprises a virtual address portion and a physical address portion. The port driver uses the virtual address portion to ascertain the location of entry structures, while the port adapter uses the physical address portion to locate the structures in a host memory. The arrangement and interpretation of the address portions of the complex pointers within an entry depend upon the direction of information flow, i.e., the passing of messages from the port driver to the port adapter using a driver-to adapter queue or the passing of responses from the adapter to the driver using an adapter-to-driver queue.
摘要翻译：双寻址装置包括在主计算机中交换信息时由端口驱动器和端口适配器使用的通信队列的条目内的复地址指针。复地址指针包括虚拟地址部分和物理地址部分。端口驱动程序使用虚拟地址部分来确定条目结构的位置，而端口适配器使用物理地址部分来定位主机存储器中的结构。条目中复杂指针的地址部分的布置和解释取决于信息流的方向，即，使用驱动程序到适配器队列将消息从端口驱动程序传递到端口适配器，或者从使用适配器到驱动程序队列的驱动程序的适配器。

摘要： A communication interface between a port driver and an port adapter of a host computer includes a singly-linked queue resident in a host memory of the computer. The queue includes a header element and a stopper element with message entries linked therebetween. The message entries contain information to be exchanged between the port driver and port adapter. Each message entry includes at least a carrier that contains a forward link pointer to the next entry in the queue and message/response specific control information. The stopper element identifies the end of the queue and is distinguishable from a message entry by a valid indicator, e.g., the state of at least one bit of the forward link pointer. Functionally, the stopper entry allows the port driver and port adapter to concurrently insert and remove message entries of the singly-linked queue in a reliable manner without the use of any external synchronization mechanism.
摘要翻译：端口驱动程序和主计算机的端口适配器之间的通信接口包括驻留在计算机的主机存储器中的单链接队列。队列包括头部元件和止动元件，其中消息条目被链接在其间。消息条目包含要在端口驱动程序和端口适配器之间交换的信息。每个消息条目至少包括载体，其包含到队列中的下一条目的前向链接指针和消息/响应特定控制信息。停止元件识别队列的结尾，并且可以通过有效指示符与消息条目区分开，例如前向链接指针的至少一个比特的状态。在功能上，阻塞条目允许端口驱动程序和端口适配器以可靠的方式同时插入和删除单链接队列的消息条目，而不使用任何外部同步机制。
