An apparatus comprises: a receiver configured to receive an image; and a processor coupled to the receiver and configured to: obtain pixels of the image; reorder the pixels to create reordered pixels; generate a first sub-image and a second sub-image using the reordered pixels; generate a first instruction to store the first sub-image in a first sub-image node; and generate a second instruction to store the second sub-image in a second sub-image node; and a transmitter coupled to the processor and configured to transmit the first instruction and the second instruction to a database.

Image storage and reconstruction based on sub-images

A system having a plurality of directors, at least some of which have a local director memory, accesses requested data by determining if requested data is in local director memory of a first one of the directors in response to an access request for the requested data by the first one of the directors. The system also determines if the requested data is native to the first one of the directors in response to the requested data not being in the local director memory of the first one of the directors, where data provided on a physical storage device coupled to the first one of the directors is native to the first one of the directors. The system also obtains the requested data from a second one of the directors in response to the requested data not being native to the first one of the directors.

Memory optimization for configuration elasticity in cloud environments

A storage node uses storage descriptors for provisioning, monitoring and reporting. The storage descriptors indicate available storage resource capabilities and storage resource requirements for particular applications or types of applications using a common set of metrics. The storage node scales requirements to approximate a particular deployment scenario and then compares available capabilities and requirements as indicated by the storage descriptors.

Storage descriptors and service catalogs in a cloud environment

Migrating data from an old storage device to a new storage device includes creating new paths to the new storage device, freezing old paths to the old storage device, transferring metadata corresponding to the old storage device to the new storage device, where state information is transferred from the old storage device to the new storage device, and thawing the new paths. Migrating data from an old storage device to a new storage device may also include creating new volumes on the new storage device and transferring data from the old storage device to the new storage device. Migrating data from an old storage device to a new storage device may also include dismantling the old paths.

Handling hibernation of a process on a storage device

Described are techniques for performing processing in a data storage system. A client application executing on a host is identified as a candidate for migration to the data storage system. First data used by the client application is stored on one or more physical storage devices of the data storage system. The client application is migrated to the data storage system for temporary execution on the data storage system. The client application is executed on the data storage system for a time period using a first portion of resources of the data storage system allocated for exclusive use by migrated client applications executing on the data storage system.

Adaptive integration of cloud data services with a data storage system

Migrating data from an old storage device to a new storage device includes transferring the data from a first logical device on the old storage device to a second logical device on the new storage device, determining replication relationships for the first logical device, transferring the replication relationships; and transferring logical devices used for the replication relationships from the old storage device to the new storage device. The replication relationships may include a clone of the first logical device. Migrating data from an old storage device to a new storage device may also include suspending writes to the first logical storage device prior to transferring the data for the first logical storage device. The replication relationships may include at least one snapshot.
