Abstract: A technique consolidates data at multiple levels of granularity, the levels including a first level based on whole PLBs (physical large blocks) and a second level based on portions of donor PLBs. The technique further includes tracking PLBs in multiple PLB queues arranged based on storage utilization of the PLBs, and tracking PLB portions in multiple portion queues arranged based on storage utilization of the portions. When consolidating data to create a new PLB, a set of whole PLBs is selected, based on utilization, from the PLB queues, and a set of portions of donor PLBs is selected, based on utilization, from the portion queues. The selections are performed such that the total data size of the selected whole PLB(s) and the selected portion(s) fit within the new PLB.

Abstract: A method, computer program product, and computing system for compartmentalizing a SSD storage tier within a storage platform into a plurality of SSD portions including a first SSD portion, a second SSD portion and a third SSD portion; reducing the size of the third SSD portion if the first SSD portion and/or the second SS portion needs to expand; and reducing the size of the second SSD portion if the first SSD portion needs to expand; wherein the storage platform includes an HDD storage tier.

Abstract: A method, computer program product, and computing system for tracking the utilization of a plurality of PLBs within a storage platform to generate PLB utilization information, wherein each PLB is associated with one or more VLBs; and tracking the utilization of the one or more VLBs associated with each of the plurality of PLBs within the storage platform to generate VLB utilization information.

Abstract: A method, computer program product, and computing system for identifying a first memory device source that includes first content; identifying a second memory device source that include second content; and initiating a first iteration of a memory device cleansing procedure wherein first content and at least a first portion of the second content are moved to a first unused memory device.

Abstract: A method is used in managing inline data de-duplication in storage systems. The method receives a request to write data at a logical address of a file in a file system of a storage system. The method determines whether the data can be de-duplicated to matching data residing on the storage system in a compressed format. Based on the determination, the method uses a block mapping pointer associated with the matching data to de-duplicate the data. The block mapping pointer includes a block mapping of a set of compressed data extents and information regarding location of the matching data within the set of compressed data extents.

Abstract: A method is used in managing copying of data in storage systems. A request is received to copy a portion of a source logical object to a target logical object. The source and target logical objects are subject to a deduplicating technique. The portion of the source logical object is copied to the target logical object by updating metadata of the target logical object. The target logical object shares the portion of the source logical object.

Abstract: A technique for preserving metadata changes in a transaction log involves coalescing metadata changes based on the block of storage in which the metadata to be changed resides. Metadata change information that accompanies a file system command is stored in nodes of a searchable data structure, wherein each node accumulates metadata changes for a respective block of storage. Once all metadata changes are specified in the searchable data structure, or after some threshold number of metadata changes have been stored, the storage processor composes a transaction for each node summarizing the metadata changes and writes the transaction to the transaction log.

Abstract: The present invention provides a system and method for abstracting multiple network attached storage (“NAS”) locations, providing a single global namespace and a single mount point that is protocol and location-independent. As a result, rather than identifying each NAS and file server by location, access is provided through a single transparent mechanism. In order to maintain transparency, the present invention provides a way to reconcile the different naming practices for different file server protocols.
