摘要： A write ordering style asynchronous replication service utilizes a loosely-accurate global clock in a data backup and recovery storage environment. The storage environment includes a set of source storage systems illustratively embodied as source replication nodes that cooperate to maintain a consistency group that may span multiple geographical sites. The storage environment also includes one or more target storage systems illustratively embodied as target replication nodes configured to service the consistency group. The write ordering style service utilizes the loosely-accurate global clock to provide consistent replication of a storage space of the consistency group.

摘要： An advanced clock synchronization technique is adapted for use with a replication service in a data backup and recovery storage environment. The storage environment includes a plurality of source storage systems and target storage systems, wherein the source storage systems are illustratively embodied as source replication nodes. The advanced clock synchronization technique establishes a software-only, loosely-accurate global clock based on a timestamp and an associated error boundary. Notably, the timestamp and its error boundary are used as global clock information to enable synchronization (i.e., ordering of storage requests) among the source replication nodes and/or the target storage systems, thereby ensuring consistent replication of the storage requests on the target storage systems.

摘要： A system and method enhances performance of a log adapted for use with a storage system. The log is illustratively organized into a plurality of regions, wherein each region comprises one or more entries and wherein each region is allocated to a consistency collection. As used herein, a consistency collection is defined as a set of one or more data containers among which it is desired to maintain transaction consistency, i.e., atomicity of updates of a transaction to those containers. Each entry of the region is adapted to store an update of data from a source, e.g., an application executing on the storage system. Thus, the consistency collection may comprise multiple data containers associated with one or more applications configured to maintain the atomicity of transaction updates to the collection of containers.

摘要： A delta query technique transmits only latest changes to data of objects from a server to one or more clients in response to a client query (request) to access the object data. A global counter is maintained for all of the objects served by the server. Every time the data of an object changes, a value of the global counter increments (updates) and the updated global counter value is then assumed (“inherited”) by that object. In addition, the global counter is updated when a client issues a request to access one or more objects. If the data of the objects has changed since the last time the client accessed the objects, the server responds with the latest object data and the updated global counter value. Notably, each client maintains a local counter having a value that, upon receipt of the latest object data, is modified to reflect the updated global counter value.

摘要： System for the storage and maintenance of data sets updates in a storage subsystem, that comprises direct access storage device(s) that serves as the main storage of the storage subsystem and on which the data sets are originally stored; a Cache memory storage device that enables fast interaction with the storage subsystem, on which a copy of the data sets is stored; a non-volatile storage device partitioned into a plurality of fixed size non-volatile memory pages. The system employs an update process, in which the changes to the data sets are applied to the data set copy stored on the Cache memory device; a journal of the changes that are being made to the data sets stored on the Cache memory device, utilizing the non-volatile memory pages to store update records reflecting the changes in the data sets; a reconstruction process in which the data sets are reconstructed utilizing the update records stored on the non-volatile memory pages, and the data sets stored on the direct access storage device; and a process for freeing arbitrary non-volatile pages from their prior association with data sets that are stored in the Cache memory.
