Abstract:
A distributed storage system comprising: an infrastructure layer including interconnected computer nodes, wherein: each one of the interconnected computer nodes comprising processing resources configured to execute a Unified Distributed Storage Platform (UDSP) agent configured to: receive a task having assignments, calculating grades for assignments such that each grade is indicative of a suitability to execute assignments while meeting at least one Service Level Specification (SLS) requirement. The grade is calculated based on storage related resources parameters data. The task is routed to a more suitable computer node based on the calculated grades. The updated infrastructure layer is created in response to adding interconnected computer nodes and executing assignments of following tasks or routing the following tasks to a more suitable computer node based on the calculated grades.

Abstract:
There are provided a computer node configured to operate in a distributed storage system (DSS) comprising interconnected computer nodes and storage-related resources and a method of operating thereon. The method comprises: detecting by the computer node in the DSS an unconnected storage-related resource connectable to the computer node; searching by a computer node a plug-in required to meet Service Level Specification (SLS) associated with the computer node, thereby giving rise to a found plug-in; and upon associating, by the computer node, the unconnected storage-related resource with the found plug-in, connecting the unconnected storage-related resource to the computer node.
Abstract:
Method and system for asynchronously dispersing Disaster Recovery (DR) enabling data between a plurality of storage sites. The method comprises: receiving, at a primary storage site, a written block and a write frequency counter associated with the written block. In case the write frequency counter is below a threshold: receiving information dispersal parameters including number indicative of a size difference between said written block and DR enabling data based on said written block; number of slices to slice said DR enabling data into and data indicative of DR storage sites of said plurality of storage sites for storing said slices. Further calculating DR enabling data based on written block, wherein DR enabling data is larger than said written block by size difference; slicing DR enabling data in accordance with number of slices; and dispersing slices in accordance with data indicative of DR storage sites.
Abstract:
A method for deploying a data-path-related plug-in for a logical storage entity of a storage system, the method comprising: deploying the data-path-related plug-in for the logical storage entity, wherein the deploying includes creating a plug-in inclusive data-path specification and wherein the plug-in inclusive data-path specification includes operation of the data-path-related plug-in; and creating a verification data-path specification, wherein the verification data-path specification does not include operation of the data-path-related plug-in and wherein a task executed in a verification data path, having the verification data-path specification, generates verification data that enables validation of given data generated by the task being executed in a plug-in inclusive data-path having the plug-in inclusive data-path specification.

Abstract:
Disclosing a storage system, method of operating thereof and data structures usable for the operating. The method includes: accommodating a plurality of data structures informative of location of allocation chunks, each allocation chunk characterized by a predefined number K of available consecutive physical addresses; wherein the predefined number K is equal for all allocation chunks indicated by the same data structure and wherein there are at least two data structures informative of location of allocation chunks with a different predefined number K; identifying, prior to writing a data chunk, a data structure associated with respective logical group and informative of location of allocation chunks with the predefined number K equal to number M of consecutive physical addresses required for storing the data chunk; and allocating for the data chunk M consecutive physical addresses in accordance with the location of the allocation chunk, the location obtained from the identified data structure.
Abstract:
A computerized system capable of continuous data protection (CDP) and method of operating thereof are provided. A CDP data structure is stored in memory. The CDP data structure includes a base snapshot acquired at a first point in time and a log. The log includes a first log region and a second log region. The log is associated with an index, which includes a first index region stored on a secondary memory and associated with the first log region, a second index region stored on a primary memory and associated with the second log region. The first log region and the second log region are updated responsive to an update of a dynamic checkpoint when the checkpoint update criterion is met. The first index region is updated responsive to the update of the first log region and the second log region, and the second index region is updated upon the update of the first index region.
