Abstract: System-level garbage collection is performed in an SSD-based data storage system employing log-structured writing of data. Respective reclaim unit sizes of the storage devices are identified, wherein each reclaim unit is a unit of programming and erasure used by device-level garbage collection to generate erased reclaim units for allocation for physical data storage. The data is arranged across the storage devices in first and second data units, each first data unit being of a first size U equal to the product of R and a stripe width W, each second data unit including a respective set of first data units which occupy a maximum-size reclaim unit of a storage device among those storing the first data units. The system-level garbage collection is operated with second-data-unit granularity to regularly generate empty second data units for allocation in the log-structured writing of data, reducing write amplification and device wear.

Abstract: Techniques for providing a virtual federation approach to increasing efficiency of processing circuitry utilization in storage nodes with a high number of cores. The techniques include, for each of two (2) physical nodes, logically partitioning a plurality of cores into a first domain of cores and a second domain of cores. The techniques include designating the first domain of cores of each physical node as belonging to a first virtual node. The techniques include designating the second domain of cores of each physical node as belonging to a second virtual node. The techniques include operating the first virtual nodes on the two (2) underlying physical nodes as a first virtual appliance, and operating the second virtual nodes on the two (2) underlying physical nodes as a second virtual appliance. In this way, scalability and speedup efficiency can be increased in a multi-core processing environment with a high number of cores.

The technique further includes generating fingerprints of blocks based on extents having the common baseline size. Fingerprint-based data mobility is then achieved by comparing extent-based fingerprints, or combinations thereof, across different storage systems to identify matching data.

Abstract: A technique provides preferential treatment to metadata over user data when protecting data in a mapped-RAID system. The technique involves generating metadata based on user data, storing the metadata in mirrored storage of the mapped-RAID system (e.g., 2-way mirrored storage), and storing the user data in non-mirrored storage of the mapped-RAID system (e.g., writing user data with parity in accordance with RAID 6). The mapped-RAID system provides reliability preference toward maintaining the metadata over maintaining the user data while the metadata and the user data are stored within the mapped-RAID system. Accordingly, the technique is able to concurrently provide high reliability and high storage efficiency.
