摘要： A backup appliance that can be disposed on a computer adapter card mid-plane internal to a data storage system. The appliance includes logic on the computer adapter card. The logic is configured for selectively allowing either directly controlling the robot picker through the fiber channel connection or indirectly controlling the robot picker by communicating with the backup server. The logic is also configured for controlling buffering of data stored in the data storage system and communicating directly with media backup drives for writing the data from buffers in the data storage system onto the backup media drives.

摘要： A mechanism to support remote mirroring of storage devices by data storage systems in a one-to-many switched environment. Each data storage system includes a disk director that is adapted to control at least one device group that is supported in a mirrored configuration with a corresponding device group controlled by one of the other data storage systems. For each device group and corresponding device group, there are first ports associated with the device group and second ports associated with the corresponding device group. A switch element is adapted to connect one of the first ports to at least one of the second ports so that data may be exchanged between the ports for each device group and corresponding device group. The disk director selects which first port is to be connected to which second port via the switch element in the establishment of a logical link. Thus, each port connected to the switch is capable of achieving multiple connections to multiple destinations for increased connectivity, redundancy and performance (load balance) without additional hardware.
摘要翻译：支持数据存储系统在一对多交换环境中远程镜像存储设备的机制。每个数据存储系统包括磁盘引导器，该磁盘引导器适于控制被镜像配置中支持的至少一个设备组与由其他数据存储系统之一控制的相应设备组。对于每个设备组和相应的设备组，都有与设备组相关联的第一个端口和与相应设备组相关联的第二个端口。开关元件适于将第一端口中的一个连接到至少一个第二端口，使得可以在用于每个设备组和对应的设备组的端口之间交换数据。在建立逻辑链路时，磁盘控制器通过交换机元件选择要连接到哪个第二端口的第一端口。因此，连接到交换机的每个端口能够实现多个连接到多个目的地，以增加连接性，冗余和性能（负载平衡），而无需额外的硬件。

摘要： A method for scanning a message-list accessible to a plurality of processors includes retrieving, from a cache associated with a scanning processor from the plurality of processors, information identifying a starting message-slot. This information is then used to begin a scan of the message-list at that starting message-slot. The information indicating the starting message-slot is obtained by identifying, in the message-list, a message-slot containing a message intended for a recipient processor from the plurality of processors and obtaining, from the identified message-slot, information indicative of a location of a succeeding message-slot in the message-list. This information is then cached, for retrieval during a subsequent scan of the message-list.
摘要翻译：用于扫描多个处理器可访问的消息列表的方法包括从多个处理器中的与扫描处理器相关联的高速缓存中检索标识起始消息时隙的信息。然后，该信息用于开始在该起始消息时隙处的消息列表的扫描。指示起始消息时隙的信息通过在消息列表中识别包含来自多个处理器的接收者处理器的消息的消息时隙来获得，并从所标识的消息时隙获得指示消息列表中的后续消息时隙的位置。然后将该信息缓存，以便在消息列表的后续扫描期间进行检索。

摘要： Providing multiple jobs for a device associated with a communication device includes providing a plurality of device records, where each of the device records corresponds to a device associated with the communication device, providing a plurality of job records for at least one of the device records, where each of the job records contains at least some information that is also provided in the corresponding one of the device records, and linking the job records and the corresponding device record so that any one of the job records may be accessed by first accessing the corresponding one of the device records. Providing multiple jobs may also include providing one of a plurality of shared pointers in each of the job records and the corresponding one of the device records, where all of the shared pointers point to the corresponding one of the device records.

摘要： This invention is a system and method for improving performance of a backup operation of data from a data storage system to a media library. In response to a computer system request to backup a slot or track of data, a data engine in communication with the system and a data storage system selectively reads the requested data. Such data engine reads may occur concurrent to host access for I/O operations by employing a protection scheme, e.g. a protection bit. Simultaneously, different backup sessions may read the same track of data that has been read by the data engine. The data slot or track remains in cache memory of the data storage system until all protection bits are reset. A requested slot or track may be moved to a sidefile stored in the cache memory if a host requested to write to it while protection bits are still set and then sent to the Data engine for transfer to a media library.
摘要翻译：本发明是用于提高数据从数据存储系统到媒体库的备份操作的性能的系统和方法。响应于计算机系统请求备份数据的时隙或轨迹，与系统通信的数据引擎和数据存储系统选择性地读取所请求的数据。这样的数据引擎读取可以通过采用保护方案，例如，与I / O操作的主机访问同时发生。一个保护位。同时，不同的备份会话可以读取数据引擎读取的相同数据轨迹。数据槽或磁道保留在数据存储系统的高速缓存中，直到所有保护位复位为止。如果主机被请求写入，而保护位仍被设置，然后发送到数据引擎以传送到媒体库，则所请求的时隙或轨道可以被移动到存储在高速缓冲存储器中的副文件。

摘要： Providing data from a volume of a remote storage device coupled to a local storage device that is coupled to a host, includes providing a command to the remote storage device to request the data, if the data is stored in a cache portion of the remote storage device, the remote storage device providing the data, and if the data is not stored in the cache portion of the remote storage device, the remote storage device causing the data to be fetched from the volume and returning one of: a disconnect or an indicator that the data was not found. Causing the data to be fetched from the volume may include creating a separate wait task that waits for the data to be fetched from the volume. The separate wait task may be created only if there is not already another wait task waiting for the same data. The wait task may post an error if the data is not fetched after a predetermined amount of time, such as four seconds. An error may be posted if the data is not fetched after a predetermined amount of time, such as eight seconds. After the data has been fetched from the volume, the remote storage device may provide a reconnect command followed by the data.
