摘要： A storage-controller-managed outboard incremental backup/restore of data. An indicator is assigned to an associated portion of data stored in a data storage device, wherein the indicator resides in a memory of a storage controller coupled to the data storage device. A value of the indicator residing within the memory of the storage controller is set when the associated portion of the data has changed. The associated portion of the data stored in the data storage device is backed using the storage controller when the value of the indicator residing within the memory of the storage controller is set. The value of the indicator residing within the memory of the storage controller is cleared when the associated portion of the data has been backed up.

摘要： Multiple competing processors cooperatively manage access to a shared resource. Each processor separately stores a lock table, listing shared resource subparts, such as memory addresses of a data storage device, for example. The lock tables are stored in nonvolatile storage. In each lock table, each subpart is associated with a “state,” such as; LOCAL or REMOTE. In response to access requests from the hosts, the processors exchange various messages to cooperatively elect a single processor to have exclusive access to the subparts involved in the access requests. After one processor is elected, the lock-holding processor configures its lock table to show the identified subpart in the LOCAL state, and all non-lock-holding processors configure their lock tables to show the identified subpart in the REMOTE state. Thus, rather than replicating one lock table for all processors, the processors separately maintain lock tables that are coordinated with each other. Importantly, each processor honors its lock table by refraining from accessing a subpart of the shared resource unless the processor's lock table indicates a LOCAL state for that subpart. In one embodiment, optimized for the two processor environment, the messages exchanged by the processors include lock request, lock release, and lock grant messages.
摘要翻译：多个竞争处理器协同地管理对共享资源的访问。每个处理器分别存储锁表，列出例如数据存储设备的共享资源子部分，例如存储器地址。锁表存储在非易失性存储器中。在每个锁表中，每个子部分与“状态”相关联，如 LOCAL或REMOTE。响应于来自主机的访问请求，处理器交换各种消息以协作地选择单个处理器以具有对访问请求中涉及的子部分的独占访问。在选择一个处理器之后，锁定保持处理器配置其锁定表以在LOCAL状态下显示所识别的子部件，并且所有非锁定保持处理器都配置其锁定表以显示REMOTE状态中标识的子部件。因此，处理器不是为所有处理器复制一个锁定表，而是分别维护彼此协调的锁定表。重要的是，每个处理器通过禁止访问共享资源的子部分来履行其锁定表，除非处理器的锁表指示该子部分的LOCAL状态。在针对两个处理器环境进行了优化的一个实施例中，由处理器交换的消息包括锁定请求，锁定释放和锁定授权消息。

摘要： A system and method for updating data. A first processing unit, such as an adaptor, receives a data update to a data block in a first storage device, such as a hard disk drive. Parity data for the data block is maintained in a second storage device, e.g., another hard disk drive. A parity group is comprised of the data block and corresponding parity data. The first processing unit determines whether the first processing unit controls access to the parity group, i.e., the state of lock ownership. The first processing unit transmits the data update to a second processing unit after determining that the first processing unit does not control access to the parity group. The second processing unit, another adaptor, performs an update after receiving the data update from the first processing unit. The first processing unit performs an update after determining that the first processing unit controls access to the parity group.

摘要： A procedure controls execution of priority ordered tasks in a multi-nodel data processing system. The data processing system includes a node with a software-controlled processor and a hardware-configured queue-controller. The queue-controller includes a plurality of priority-ordered queues, each queue listing tasks having an assigned priority equal to a priority order assigned to the queue. The queue-controller responds to a processor generated order to queue a first task for execution, by performing a method which includes the steps of: listing said first task on a first queue having an assigned priority that is equal to a priority of said first task; if a second task is listed on a queue having a higher assigned priority, attempting execution of the second task before execution of the first task; if no tasks are listed on a queue having a higher assigned priority than said first queue, attempting execution of a first listed task in the first queue means; and upon completion of execution of the task or a stalling of execution of the task, attempting execution of a further task on the first queue only if another order has not been issued to place a task on a queue having a higher assigned priority. The method further handles chained subtasks by attempting execution of each subtask of a task in response to the processor generated order; and if execution of any subtask does not complete, attempting execution of another task in lieu of a subtask chained to the subtask that did not complete.

摘要： A method enables a host processor, which employs variable length (VL) records, to communicate with disk storage which employs fixed length (FL) sectors for storage of the VL records. The method comprises the steps of: a) deriving a first control data structure for an update VL record, the first control data structure including information describing segments of the update VL record; b) determining a disk track that includes a FL sector wherein am old VL record commences that corresponds to the update VL record; c) reading each FL sector in the disk track and creating a control data structure which includes information describing each VL record stored in the disk track; d) substituting in a control data structure for the old VL record that corresponds to the update VL record, information regarding update data from the first control data structure; e) recording in the disk track, data indicated by each control data structure determined in steps c) and d); and f) if the old VL record ends at other than a sector break of a FL sector, reblocking VL records into FL sectors which are recorded thereafter on the disk track. The invention also enables a read action to be accomplished in one rotation of a disk even though it commences at a FL sector that is not at the beginning of a VL record to be accessed.

摘要： In a data processing system employing a disk array, prediction of a possible failure of a disk drive initiates copying of the data away from the potentially failing disk drive to a spare disk drive before the failing drive actually fails. If the disk drive does fail before the copying of the contents to a spare disk drive is completed, rebuilding of the remaining contents within the failing disk drive is performed.

摘要： A constant size storage can be managed to preserve locality of referencing where it is partitioned into linear addressable storage space for compressed symbol strings and a linked list addressable space for overflowing portions of each compressed string, a token to the overflow being embedded in the linear address. The linear space is readjusted periodically in a direction so as to maintain the amount of available overflow within to lie within a certain range of current usage. Changes in compression statistics result in changing overflow usage requiring readjustment to minimize internal fragmentation etc.

摘要： An intelligent router routes a user request to a storage server that is capable of handling that request natively, without emulation. The request is routed automatically, without any instruction or interaction on the part of the user. The intelligent router includes a storage tank-like computing environment and a set of intelligent routers. The set of intelligent routers appears as a single entity to users by presenting a single network IP address. When the intelligent router receives a request, it examines the protocol type and routes the request to one of the appropriate storage tank clients. The intelligent router does not change the contents of the request message, and thus the storage tank system do not become aware of the existence of the intelligent router. Consequently, any return messages do not need to go through the intelligent router, unless desired.

摘要： Systems and methods of increasing the performance of computer networks, especially networks connecting users to the Web, are provided. Performance is increased by reducing the latency the client experiences between sending a request to the server and receiving a response. A connection is obtained by a client device to the network target node addressed by a physical I/O address, to more quickly respond to requests for resource files on data storage devices. This enhancement may be implemented by connecting the controller of the data storage device directly to the network, to reduce the latency involved in mapping the logical I/O address into a physical I/O address. In that case the requested resource file is sent to the client directly by the data storage device controller, thus saving time otherwise spent in sending the request and data between computer network components.
