Systems and methods for storage pruning can enable users to delete, edit, or copy backed up data that matches a pattern. Storage pruning can enable fine-grain deletion or copying of these files from backups stored in secondary storage devices. Systems and methods can also enable editing of metadata associated with backups so that when the backups are restored or browsed, the logical edits to the metadata can then be performed physically on the data to create a custom restore or a custom view. A user may perform operations such as renaming, deleting, modifying flags, and modifying retention policies on backed up items. Although the underlying data in the backup may not change, the view of the backup data when the user browses the backup data can appear to include the user's changes. A restore of the data can cause those changes to be performed on the backup data.

A storage system comprises stripes, extents comprised in one stripe among the stripes residing on storage devices in the storage system, respectively. A failed stripe is determined among the stripes, the failed stripe comprising a group of failed extents residing on a group of failed storage devices, respectively, a number of failed storage devices in the group being less than or equal to parity width of the storage system. Distribution of the group of failed extents in the failed stripe is obtained. A rebuild parameter for rebuilding data in the failed stripe is generated based on the obtained distribution. The generated rebuild parameter is stored for rebuilding the storage system. Accordingly, a rebuild parameter generated for one failed stripe is reused for other failed stripe with the same distribution. The performance of rebuild operations may be improved, and time of rebuild operations may be reduced.

A memory system includes a non-volatile memory device and a controller. The non-volatile memory device performs operations in parallel on a plurality of memory blocks. The controller determines, in response to a read request on a plane including a target memory block among the plurality of memory blocks, whether to perform a process for a partial suspension on the operations based on suspension counts of the plurality of memory blocks. The controller controls, when performing a process for the partial suspension, the non-volatile memory device to suspend the operation being performed on the target memory block and to keep performing the operations being performed on other memory blocks among the plurality of memory blocks.

A method includes determining an encoded data slice of a first subset of encoded data slices associated with a set of encoded data slices requires rebuilding, where the first subset of encoded data slices is stored in a set of storage units and includes at least a decode threshold number of encoded data slices. The method further includes identifying a second encoded data slice of a second subset of encoded data slices of the set of encoded data slices, where the second subset of encoded data slices is not currently stored in the set of storage units. The method further includes generating the second encoded data slice from the first subset of encoded data slices and sending the second encoded data slice to the set of storage units, where when stored, the second encoded data slice no longer included in the second subset of encoded data slices.

Provided is a data processing system which includes a processor and a storage device, and inputs/outputs data using a learned compander that compresses and expands data, wherein the data processing system comprises an estimation unit which uses learning data and estimates a region of interest to a data model, and a learning unit which causes the compander to learn according to an evaluation function in which each region was weighted based on the region of interest, and a result of the compander compressing and expanding the learning data.

A data processing system is provided to include a storage unit and a controller in communication with the storage unit and configured to program write data to a first area as at least one of the plurality of storage areas with a priority over a second area as at least one of the plurality of storage areas and transfer data of the first area to the second area. The controller is further configured to adjust a size of the first area based on 1) a number of times saturated by the write data for the first area, a saturation occurring due to a size of the write data written to the first area being greater than a certain size and 2) an overflow size of the write data corresponding to a difference between the size of the write data and the certain size.

A solid state drive (SSD) employing a redundant array of independent disks (RAID) scheme includes a flash memory chip, erasable blocks in the flash memory chip, and a flash controller. The erasable blocks are configured to store flash memory pages. The flash controller is operably coupled to the flash memory chip. The flash controller is also configured to organize certain of the flash memory pages into a RAID line group and to write RAID line group membership information to each of the flash memory pages in the RAID line group.

The present technology pertains to a organization directory hosted by a synchronized content management system. The corporate directory can provide access to user accounts for all members of the organization to all content items in the organization directory on the respective file systems of the members' client devices. Members can reach any content item at the same path as other members relative to the organization directory root on their respective client device. In some embodiments novel access permissions are granted to maintain path consistency.

Systems, apparatuses, and methods related to multiple artificial neural networks (ANNs) in memory. Such ANNs can be implemented within a memory system (including a number of memory devices) at different granularities. For example, multiple ANNs can be implemented within a single memory device and/or a single ANN can be implemented over multiple memory devices (such that multiple memory devices are configured as a single ANN). The memory system having multiple ANNs can operate each ANN independently from each other such that multiple ANN operations can be concurrently performed.

A method for performing ONU Management and Control Interface (OMCI) synchronization includes receiving an OMCI message containing a OLT-G entity identifying OLT's vendor identification (ID) and version. The method also includes determining if an OLT vendor identification (ID) matches with a current vendor ID and if an Optical Line Terminal (OLT) version is compatible with current OMCI handlers. When the OLT vendor ID fails to match with the current vendor ID, automatically performing a OMCI handler switching process. The OMCI handler switching process includes setting a current OLT vendor as a new OLT vendor ID, deleting a OMCI configuration previously stored in the flash memory after setting the new OLT vendor ID, and rebooting the ONT to allow the ONT to initialize a OMCI configuration using a new OMCI profile.
