摘要： A procedure for scheduling multiple process requests for read/write access to a disk memory device within a computer system. The procedure considers disk characteristics, such as the number of sectors per track, the number of tracks per cylinder, speed of disk rotation and disk controller queuing capability in determining the optimal order for executing process requests. Process requests are placed in packets within an execution queue, each packet including up to a predetermined maximum number of requests. Within the packets, the process requests are sorted in ascending/descending order by the cylinder number to which the requests desire access, while within each cylinder the requests are placed in next-closest-in-time sequence.

摘要： In a storage environment or storage area network having multiple host devices and at least one storage array, the host devices access logical data volumes stored on the storage array through array controllers disposed in the storage array. Multiple host devices can request access to shared ones of the logical data volumes through multiple paths to multiple array controllers, but each logical data volume is controlled or owned by only one array controller at a time. Thus, ownership of shared logical data volumes is transferred between the array controllers as necessary on behalf of the requesting host devices. To prevent ownership transfers from occurring too often, however, ownership of the logical data volumes is made exclusive, or “sticky,” for a period of time after each transfer. During the exclusive ownership period of time, the ownership cannot be transferred. After expiration of the exclusive ownership period of time, ownership of the affected logical data volume is transferred if the transfer does not cause another host device to lose access to the same logical data volume, unless priorities between competing host devices permit one host device to take access away from the other host device.
摘要翻译：在具有多个主机设备和至少一个存储阵列的存储环境或存储区域网络中，主机设备通过设置在存储阵列中的阵列控制器访问存储在存储阵列上的逻辑数据卷。多个主机设备可以通过到多个阵列控制器的多条路径来请求对共享的逻辑数据卷的访问，但每个逻辑数据卷一次只由一个阵列控制器控制或拥有。因此，共享逻辑数据卷的所有权在必要时代表请求的主机设备在阵列控制器之间传送。然而，为了防止所有权转让发生太频繁，逻辑数据卷的所有权在每次传输后的一段时间内被排除在外或“粘性”。在独家所有制期间，所有权不能转让。在独占所有权期限届满后，如果转移不会导致另一个主机设备不能访问相同的逻辑数据卷，则转移受影响的逻辑数据卷的所有权，除非竞争的主机设备之间的优先级允许一个主机设备采取远离其他主机设备。

摘要： An apparatus and method for determining the power consumption of one or more disk arrays are described. Power consumption information for various hardware components of the array, especially that for the disk drives since these consume more than 90% of the required power, are stored in a static data table in a database which may be controller firmware. Through inspection of this table and the chosen state of the individual disk drives as directed by a controller, one may determine the power use of the array.

摘要： A host computer environment includes a driver stack having a disk driver and a host bus adapter (HBA) driver. The driver stack further includes a multipath driver functionally embedded between the disk driver and HBA driver. At this hierarchical layer of the driver stack, the multipath driver functions at the command transport protocol level. The disk driver effectively views the multipath driver as a HBA driver type, while the HBA driver effectively views the multipath driver as a disk driver type. The multipath driver is configured to instantiate proxy virtual paths to the disk array that are visible to the host operating system but otherwise conceal the underlying physical paths. The multipath driver retains knowledge of the mapping between the physical and virtual paths. The disk array is configured to report itself to the OS as a non-disk device type, although its true identity is known by the multipath driver.

摘要： A system for updating management entities or devices in a computer system network with configuration change information from the devices being managed. The management entities are configured to discover, monitor and configure managed devices, such as storage systems, connected to the network. Preferably, the managed devices include a comparator which can track changes made to the managed device configuration or properties and report that change back to the various management entities. In this way, the management entities can keep track of the configurations of the various devices that they manage, even though they might not be responsible for issuing the configuration change. This can be accomplished even when managed devices developed by different manufacturers according to different standards or protocols are involved.

摘要： The present invention provides for a method and computer program product for handling timeout in a standard RPC connection. First, a client establishes a connection with a server with unique identification. After submitting an RPC request, the client system will periodically make secondary requests to the server to determine if the server is still actively processing the primary RPC request. If the secondary request is processed successfully and the server indicates that the primary request is still in progress, the client will continue to wait until either the primary request completes or enough time elapses to warrant another secondary request. The success of the secondary request hinges on finding a match of identification for the primary and secondary requests. If the secondary request fails, this failure is treated as a sign that there is either a network or a server problem, and the client is triggered into taking appropriate corrective action. To provide for a reasonably graceful failure mechanism, this polling protocol can be modified to require a predetermined number of successive secondary poll failures before signaling a failure of the primary RPC request.

摘要： A system and method for managing device configuration changes. The system and method preferably comprises a management station which issues a configuration change request to a management device and waits for a reply from the managed device. The managed device receives the configuration change request from the management station and processes the change request until the configuration change request is durable on the managed device. The managed device then returns a status to the management station indicating that the configuration request is durable. The management station receives the status from the managed device and stops waiting for reply. In the meantime, the managed device continues processing the configuration change request. In addition, the system and method preferably further comprises that after the management station receives the status from the managed device and stops waiting for a reply, the management station preferably starts and event completion status object which shows the completion status of the configuration change request being processed on the managed device.
