摘要： A read/write ratio for each of a plurality of data segments classified in a hot category as hot data segments is determined. Each of the plurality of hot data segments is ordered by the read/write ratio in a descending order. Each of a plurality of available SSD devices is ordered by a remaining life expectancy in an ascending order. Those of the plurality of hot data segments are matched with those of the plurality of hot data segments with those of the plurality of available SSD devices such that a hot data segment having a higher read/write ratio is provided to an SSD device having a smaller remaining life expectancy than another hot data segment having a lower read/write ratio.

摘要： A method for migrating extents between extent pools in a tiered storage architecture maintains a data access profile for an extent over a period of time. Using the data access profile, the method generates an extent profile graph that predicts data access rates for the extent into the future. The slope of the extent profile graph is calculated and used to determine whether the extent will reach a migration threshold within a specified “look-ahead” time. If so, the method calculates a migration window that allows the extent to be migrated prior to reaching the migration threshold. In certain embodiments, the method determines the overall performance impact on the source extent pool and destination extent pool during the migration window. If the overall performance impact is below a designated impact threshold, the method migrates the extent during the migration window.

摘要： A method for more effectively distributing the I/O workload in a data replication system is disclosed herein. In selected embodiments, such a method may include generating an I/O request and identifying a storage resource group associated with the I/O request. In the event the I/O request is associated with a first storage resource group, the I/O request may be directed to a first storage device and a copy of the I/O request may be mirrored from the first storage device to a second storage device. Alternatively, in the event the I/O request is associated with a second storage resource group, the I/O request may be directed to a second storage device and a copy of the I/O request may be mirrored from the second storage device to the first storage device. A corresponding system, apparatus, and computer program product are also disclosed and claimed herein.

摘要： In one embodiment of a computer-implemented system, comprising a plurality of computer entities and multiple resources, one of the computer entities may request a multi-resource lock to one of the multiple resources; the one resource determines whether a resource lock is available at the one resource and, if so, the one resource communicates with all peer resources to determine whether a resource lock is available; if the peer resources indicate a resource lock is available, lock all of the resources to the requesting computer entity, and the one resource communicates the lock of the resources to the requesting computer entity; and if any the resource indicates contention for the multi-resource lock, the one resource communicates the contention to the requesting computer entity, and the requesting computer entity backs off the multi-resource lock request and, after a random time interval, repeats the request.

摘要： Various method and system embodiments for updating software on end hosts in computing environments and particularly storage environments are provided. A remote server pushes the software update image to and through a local server via a network connection and high-throughput channels and to the end host via low-throughput channels. The local server manages the update process; the remote server simply pushes the software update image and the end host simply receives and applies an update. The local server stores the current software image running on the end host and decides whether it is more efficient to simply send the software update image on or to create, send and apply a patch at the end host. This approach reduces the update time of the end host, reduces any disruption of normal message traffic to and from the end host and simplifies patch management.

摘要： A method to detect component removal while operating in a battery backup mode, comprising providing power from a battery backup unit (“BBU”) to a control card memory device, and measuring the current drawn by the control card memory device. If the current drawn by the control card memory device is less than or equals a pre-determined disconnect current, the method determines if a BBU release pin has been asserted. If the BBU release pin has been asserted, the method encodes in an event log a battery backup removal event. If the BBU release pin has not been asserted, the method encodes in the event log a control card removal event.
