Abstract: Various aspects for managing data blocks in a storage system are provided. For instance, a method may include storing, in a buffer memory, a plurality of comparison blocks, initiating a data deduplication process utilizing the plurality of comparison blocks, and performing garbage collection in conjunction with the data deduplication process. Garbage collection may include maintaining a hit count for comparison blocks of a passive set of comparison blocks in the buffer memory and deleting the passive set from the buffer memory when the hit count is decremented to a predetermined value. The hit count may be incremented and decremented based on utilization of a comparison block in the data deduplication process.

Abstract: A sequence of contiguous pages in an erase block in a non-volatile memory device is programmed and erased. Next, all of the pages in the erase block are programmed with data. Then, the data is read back and verified to determine whether there is an error in the data. When there is an error in the data, then the last page in the sequence is identified as being unstable. If there is no error in the data, then the last page in that sequence is identified as being stable. Thus, the recorded information identifies a point of instability in the erase block. Instabilities can be stabilized by performing additional writes to fill the partially filled word line.

Abstract: In an embodiment, a client device obtains a list of client devices registered in association with a particular client application, and then detects listed client device(s) as proximate via a local communications interface. One of the proximate client devices is identified as responsible for sending an aggregated registration request message for renewing their respective application registrations with a server. In another embodiment, the server receives a registration message for the client application from a client device and detects that at least one other registered client device for that client application is proximate to the requesting client device. The server attempts to preemptively renew the registrations for both the requesting client device and the at least one other registered client device based on the proximity detection.
