摘要： Configuration changes are dynamically applied to a cluster multiprocessing system by enqueuing a configuration change event. When the configuration change event is processed, the prior configuration is backed up and each software component applies a relevant portion of a configuration change transaction in an ordered, synchronized manner. Each software component applies its portion of the transaction either by reinitialization or a logged transition operation. If the configuration change transaction fails, the software components roll back the portions, of the configuration change already applied in an ordered, synchronized manner to restore the prior configuration. Multiple events for different configuration changes may be enqueued.

摘要： A disk controller connected to a set of disks in a data storage system is configured to mirror a first class of data on multiple disks while storing a second class of data without mirroring. The controller maintains at least one of the disks containing the first class of data in an operational state while maintaining at least one of the remaining disks in a low power state. The first class of data may contain popular files while the second class of data contains unpopular files. The first data class may be mirrored on each of the disks. The data in the second class may be stored with parity where the parity information is maintained on a single disk. The operational disk may be changed following access to data from the second class of data that is stored on one of the low power state disks.

摘要： A data storage system includes a set of disks where each disk is operable in a plurality of discrete angular velocity levels. A disk controller controls the angular velocity of each active disk. The controller replicates a first portion of data on a plurality of the disks stores a second class of data in the set of disks without replication. The disk controller routes data requests to one of the active disks based, at least in part, on the current loading of the active disks to maintain balanced loading on the active disks. The disk controller alters the angular velocity of at least one of the active disks upon detecting that the latency of one or more of the data requests differs from a specified threshold. In this manner, the disk controller maintains the angular velocity of the active disks at approximately the same minimum angular velocity needed to attain acceptable performance. The disk controller may replicate the first portion of data on each of the disks in the set of disks. The disk controller may balance the loading on the active disks by routing an incoming request to the active disk with the least loading. The disk controller may maintain each of the active disks at approximately the same angular velocity by preventing the angular velocity of any active disk from differing from the angular velocity of any other active disk by more than one discrete level. The disk controller may recognize two or more levels of request priorities. In this embodiment, the disk controller routes requests of a first priority to an active disk in a first subset of active disks based, at least in part, on the current loading of the disks in the first subset and route requests of a second priority to an active disk in a second subset of active disks based, at least in part, on the current loading of the disks in the second subset.

摘要： A method, system, and computer usable program product for local synchronization in a memory hierarchy in a multi-core data processing system are provided in the illustrative embodiments. A request to acquire a reservation for a reservation granule is received at a first core. The reservation is acquired in a first local cache associated with the first core in response to a cache line including the reservation granule being present and writable in the first local cache. A conditional store request to store at the reservation granule is received at the first core. A determination is made whether the reservation remains held at the first local cache. The store operation is performed at the first local cache responsive to reservation remaining held at the first local cache.

摘要： A system and method for operating a server cluster that includes a set of server devices connected to a local area network (LAN). Each server device maintains a directory of the contents of its file cache. When a decrease in server cluster traffic is detected, a server device on the server cluster is selected for powering down. Prior to powering down a server device, the device's file cache directory is broadcast over the LAN to each of the other server devices on the cluster. If a subsequent request for a file stored in the powered-down server's file cache is received by the cluster, the request is routed to one of the remaining active server devices. This server device then retrieves the requested file from the powered-down server's file cache over the LAN. Prior to broadcasting the file cache directory, pending client requests on the selected server device are completed. The powered-down server may continue to provide power to its NIC and system memory while the processor is deactivated. The server device NIC may include direct memory access capability enabling the NIC to retrieve files from the system memory while the processor is powered-down.

摘要： A data storage system in which each of a set of disks has a first portion for either popular data or error correction information (parity or Reed-Solomon code symbols) associated with the popular data, and a second portion used for other data. A disk controller connected to the set of disks maintains a first popular data block in the first portion of a first of the set of disks and a second popular data block in the first portion of a second of the set of disks. The system maintains at least two of the disks in an active state. The active disks are selected to insure that any data in the popular data blocks can be determined from data stored in the active disks. An additional disk is maintained in an active state if write access is permitted or if there is an additional popular data block.

摘要： A method and system for responding to a client request for information from a service device in a data processing network. Initially, the server receives the information request from the client and determines that the requested information is not in the server's cache. The server then generates a storage request and sends the storage request to a network attached storage device. The storage device retrieves the requested information and generates a set of packets containing the requested information. The storage device then sending the generated packets simultaneously to the client to satisfy the client request and to the server to refresh the server cache. The storage request may include protocol information corresponding to the client-server connection that the storage device uses to replicate the client-server protocol stack in the generated packet. Sending the generated packet may comprise including a multicast address in the packet.
