摘要： Providing continuous backup of a storage device includes subdividing the storage device into subsections, providing a time indicator that is modified periodically, and, in response to a request to write new data to a particular subsection of the storage device at a particular time, maintaining data being overwritten by the new data according to the particular subsection and according to a value of the indicator at the particular time. The subsections may be tracks. Maintaining the data being overwritten may include constructing a linked list of portions of data for each of the subsections. The portions of data may have variable sizes. In response to two data write operations to a particular subsection at a particular value of the indicator, data being written for each of the two data write operations may be combined if data for the second data write operation is a subset of data for the first data write operation. Providing continuous backup of a storage device may also include restoring the storage device to a state thereof at a particular point in time by writing the maintained data to the storage device. Writing the maintained data to the storage device may include constructing subsections of the data by combining separate portions thereof corresponding to the same subsection.

摘要： Providing continuous backup of a storage device includes subdividing the storage device into subsections, providing a mirror device of the storage device that contains a copy of data that is on the storage device when the continuous backup is initiated, providing a time indicator that is modified periodically, and, in response to a request to write new data to a particular subsection of the storage device at a particular time, maintaining data being overwritten by the new data according to the particular subsection and according to a value of the indicator at the particular time, where, for a first write after the continuous backup is initiated, data from the mirror device is used to maintain data being overwritten. The subsections may be tracks. Maintaining the data being overwritten may include constructing a linked list of portions of data for each of the subsections. The portions of data may have variable sizes.

摘要： 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.

摘要： Migrating an active VM from a first data center to a second data center having a passive counterpart of the active VM includes freezing the active VM at the first data center, creating an active VM at the second data center that corresponds to the passive counterpart, and restarting the active VM at the second data center. Migrating an active VM from a first data center to a second data center may also include waiting for the passive counterpart to be synchronized with the active VM at the first data center prior to converting the passive counterpart. Creating the active VM at the second data center may include providing a snapshot of a volume containing the passive VM.

摘要： 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.

摘要： Described are techniques for performing dynamic binding of device identifiers to data storage devices. A first device identifier assigned to an application on a host is received. The first device identifier is a unique detachable device identifier dynamically bound to different data storage devices at different points in time in accordance with data storage devices used by the application. The first device identifier is attached to a first data storage device of the data storage system used by the application at a first point in time. The first device identifier is detached from the first data storage device thereby making the first data storage device unavailable for data operations from the application. The first device identifier is attached to a second data storage device used by the application at a second point in time thereby making the second data storage device available for data operations from the application.

摘要： Sharing at least one link among a plurality of processes includes determining a capacity of the at least one link based on a number of I/O operations per unit time supported by the at least one link as a function of the amount of data provided by each of the I/O operations, determining a requirement of each of the processes based on user specifications and an amount of data provided by each I/O operation for each of the processes, and apportioning link capacity among the processes according to the requirement of each of the processes. In response to a sum of requirements for each of the processes being less than the capacity of the at least one link, additional link capacity may be provided to at least some of the processes.
