摘要： When data is stored in many storage subsystems, metadata, such as a sequence number, is also generated and stored with the data. When the data is accessed, the metadata is checked to ensure that the desired data element has been accessed. In conventional storage subsystems, data elements, such as logical blocks, are stored sequentially in logical pages of each logical volume. Consequently, sequence numbers closely correlate with block positions within the physical pages and sequence number/position patterns tend to repeat frequently and access errors may not be detected. Algorithms are provided to calculate new, offset, physical block positions which reduce the close association of sequence numbers and physical positions, thereby reducing such aliasing. The algorithms incorporate the logical volume number, the logical page number, or both, in addition to the logical block number. As a result, detection of access errors becomes more likely.

摘要翻译： 当数据存储在许多存储子系统中时，还会生成数据，如序列号，并与数据一起存储。 当访问数据时，将检查元数据，以确保已访问所需的数据元素。 在传统的存储子系统中，诸如逻辑块的数据元素被顺序存储在每个逻辑卷的逻辑页面中。 因此，序列号与物理页面内的块位置密切相关，并且序列号/位置模式往往频繁地重复，并且可能不检测到访问错误。 提供算法来计算新的，偏移的物理块位置，减少序列号和物理位置的紧密关联，从而减少这种混叠。 除了逻辑块号之外，算法还包含逻辑卷号，逻辑页号或两者。 结果，访问错误的检测变得更可能。

摘要： A computer system includes a support system that report events, faults, and failures to a master virtual server. While the support system may be accessed and used by a multitude of virtual servers, only the master virtual server can manage the support system. The support system include a master lock register, a heartbeat timer, and a digital processing device (“processor”). Upon initialization and if the master lock register is empty, a virtual server asserts ownership over the support system by writing its identification into the master lock register, becoming the master virtual server. The master virtual server transmits periodic heartbeats to the support system to communicate that it is still viable and in control. If the heartbeat timer expires without communication from the master virtual server, the processor clears the master lock register and transmits a broadcast message inviting all connected virtual servers to attempt to assert control.

摘要： A data saving device, system, and method rapidly and deterministically saves data of a computer system. The device may mark data that must be saved when the computer is shut down. In certain embodiments, a boot control module detects a condition requiring a rapid deterministic data saving operation, such as a power failure and reboots the computer, deterministically terminating all existing processes. Additionally, the boot control module loads a data transfer kernel in place of a standard operating kernel used for normal operation. The data transfer kernel supports a set of processes exclusively dedicated to saving data. The data transfer kernel configures the computer and storage devices for the data transfer and saves the marked data with a minimum of interruptions from other processes. Also, the data transfer kernel may shut down the computer and the storage devices after transferring data.

摘要： A data storage system includes a host computer, a data storage device, and a communication bus connecting the host computer to the data storage device. The host computer is adapted to issue a specialized initiation command, such as a format command with a unique parameter or a unique send diagnostic command. Once received by the data storage device, the specialized initiation command is decoded by a command processor which, in turn, directs a memory controller to execute an internal initiation of target sectors residing on data storage media within the data storage device. The memory controller places sector data in a temporary memory device, such as a random-access memory (“RAM”), including a plurality of zeroes appended to a logical redundancy check (“LRC”) value. Once compiled, this sector data is written to the data storage media. In this way, target sectors of the data storage media are initialized with LRC information without requiring large amounts of data being transmitted over the communication bus.

摘要： An apparatus, system, and method are disclosed for facilitating copy protection. The apparatus includes a definition module, a request module, and a determination module, each coupled to a first storage sub-system. The definition module is configured to define a protection definition for a plurality of electronic storage devices of the first storage sub-system. The request module is configured to receive a copy request from a second storage sub-system. The determination module is configured to determine at the first storage sub-system a copy protection status of a destination device. The copy protection status may be indicated by the protection definition, which includes a protection indicator and may include one or more restriction indicators. The apparatus advantageously allows a user to protect a selected destination device against accidental or otherwise detrimental copying.

摘要： Methods, system and computer program product are provided to configure a path between nodes through a fabric in a fibre channel storage area network (SAN). A node name is provided for a target node on the SAN and a port name is provided for each port in the target node. A relationship is established in a data structure between each port name and a slot in which each port is physically located in the target node. Prior to configuring a path between a source node and a port in the target node, the ports which are physically connected and logged in to the fabric are identified by port address. The port names corresponding to the port addresses are then identified. The port names are used to generate interface_ids of the ports corresponding to the physical slots in which the ports are located. A data structure is created to maintain the relationship between interface_ids and port names. To establish a path connection between a port in the source node and a selected port in the target node, the node name of the target node and the interface_id of the selected port are input to the data structure and the port name of the selected port is output. The port name is then used to obtain the address of the selected port and an I/O session path opened between the source and target nodes.
