摘要： A mechanism is provided in a data processing system. The mechanism determines a maximum queue depth of a queue for each solid state drive in a plurality of solid state drives. A given data block is mirrored between a group of solid state drives within the plurality of solid state drives. The mechanism tracks outstanding input/output operations in a queue for each of the plurality of solid state drives. For a given read operation to read the given data block, the mechanism identifies a solid state drive within the group of solid state drives based on a number of empty slots in the queue of each solid state drive within the group of solid state drives.

摘要： A cluster system includes a plurality of computing nodes connected to a network, each node including one or more storage devices. The cluster system stores data and at least one of data replicas or erasure-coded segments across the plurality of nodes based on a redundancy policy. Further, configuration information, which may be indicative of a data placement of the data and the data replicas or erasure-coded segments on the plurality of nodes, is provided to each of the plurality of nodes. Additionally, each of the nodes may act as a first node which is configured to determine, upon a change of the redundancy policy, updated configuration information based on the change of the redundancy policy and to send a message including information indicating the change of the redundancy policy to the other nodes of the plurality of nodes.

摘要： A system and method for maintaining operation of a storage array with one or more failed storage devices and for quickly recovering when failing devices are replaced are provided. In some embodiments, the method includes receiving a data transaction directed to a volume and determining that a storage device associated with the volume is inoperable. In response to determining that the storage device is inoperable, a data extent is recorded in a change log in a storage controller cache. The data extent is associated with the data transaction and allocated to the storage device that is inoperable. The data transaction is performed using at least one other storage device associated with the volume, and data allocated to the storage device is subsequently reconstructed using the recorded data extent.

摘要： A method for mirroring in three-dimensional-stacked memory includes receiving a plurality of thermal profiles from a plurality of memory chips. The method also includes ranking the plurality of memory chips in a first ranked list of memory chips as a function of the plurality of thermal profiles and forming a first group of memory chips from the plurality of memory chips based on the first ranked list of memory chips. The method also includes forming a second group of memory chips from the plurality of memory chips distinct from the first group of memory chips based on the first ranked list of memory chips. The method also includes pairing a first memory chip from the first group of memory chips and a second memory chip from the second group of memory chips, and mirroring the pairing of memory chips.

摘要： For replicating a source storage system, a scan module generates a source storage server description for each source storage server of the source storage system from a scan of the source storage system. The source storage server description includes a replication type and a source volume record for each source logical volume of the source storage server. A provision module determines a number of replicated instances of each source logical volume for a target storage system from the replication type. In addition the provision module generates a target storage server description for each target storage server of the target storage system from each source storage server description in response to the target storage system satisfying a target storage requirement.

摘要： Methods, systems, and configured storage media are provided for flexible data mirroring. In particular, the invention provides many-to-one data mirroring, including mirroring from local servers running the same or different operating systems and/or file systems at two or more geographically dispersed locations. The invention also provides one-to-many data mirroring, mirroring with or without a dedicated private telecommunications link, and mirroring with or without a dedicated server or another server at the destination(s) to assist the remote mirroring unit(s). In addition, the invention provides flexibility by permitting the use of various combinations of one or more external storage units and/or RAID units to hold mirrored data. Spoofing, SCSI and other bus emulations, and further tools and techniques are used in various embodiments of the invention.

摘要： A method, system, and computer program product for managing upgrades of database systems using a transparently-patched seed data table. The method commences on a running system by copying (while software applications are running) portions of data comprising a seed data table to database table rows that are temporarily inaccessible by the software applications. The copy operation creates new rows (a seed data table copy) in a database table. The method continues while software applications are running by modifying the seed data table copy (e.g., by applying a patch). For a brief time, the method stops the software applications, then changes the database table rows that were temporarily inaccessible by the software applications to become accessible by the software applications and restarts the software application to point to the patched seed data table copy. The patch can add or change a column of the seed data table copy or its schema.
