Abstract: Methods and apparatuses for updating members of a data storage reliability group are provided. In one exemplary method, a reliability group includes a data zone in a first storage node and a checksum zone in a second data storage node. The method includes updating a version counter associated with the data zone in response to destaging a data object from a staging area of the data zone to a store area of the data zone without synchronizing the destaging with the state of the checksum zone. The method further includes transmitting, from the data zone to the checksum zone, an update message indicating completion of the destaging of the data object, wherein the update message includes a current value of the version counter.

Abstract: A storage system provides highly flexible data layouts that can be tailored based on reliability considerations. The system allocates reliability values to logical containers at an upper logical level of the system based, for example, on objectives established by reliability SLOs. Based on the reliability value, the system identifies a specific parity group from a lower physical storage level of the system for storing data corresponding to the logical container. After selecting a parity group, the system allocates the data to physical storage blocks within the parity group. In embodiments, the system attaches the reliability value information to the parity group and the physical storage units storing the data. In this manner, the underlying physical layer has a semantic understanding of reliability considerations related to the data stored at the logical level. Based on this semantic understanding, the system has the capability to prioritize data operations on the physical storage units according to the reliability values attached to the parity groups.

Abstract: A method of performing a global deduplication may include: collecting a data chunk to be written to a backing storage of a storage system at a staging area in the storage system; generating a data fingerprint of the data chunk; sending the data fingerprint in batch along with other data fingerprints corresponding to data chunks collected at different times to a metadata server system in the storage system; receiving an indication, at the staging area, of whether the data fingerprint is unique in the storage system from the metadata server system; and discarding the data chunk when committing a data object containing the data chunk to the backing storage, when the indication indicates that the data chunk is not unique.

Abstract: Described herein is a system and method for an efficient cache warm-up. The system and method may copy data blocks from a primary storage device to a cache memory device. The system and method may identify a subset of data blocks stored on the primary storage device as candidate data blocks for copying to the cache memory device during a cache warm-up period. A cost effectiveness for copying the candidate data blocks to the cache memory device may be determined. In some embodiments, the cost effectiveness may be calculated based on one or more latency values associated with the primary storage device and the cache memory device. The candidate data blocks may be copied to the cache memory device based on the cost effectiveness.

Abstract: System and method for processing cache metadata from a plurality of cache devices. One or more storage systems may store data blocks to a set of storage devices, each storage system hosting and operating one or more cache devices for caching data blocks of the storage devices. Each cache device may host and implement an agent engine that collects and stores cache metadata for the cache device, the cache metadata describing caching operations of the cache device. A monitor engine receives and aggregates “raw cache metadata” from each of a plurality of cache devices and processes the raw cache metadata to produce processed cache metadata comprising normalized cache metadata (based on activity rate of a cache device), weighted cache metadata, or normalized weighted cache metadata. The processed cache metadata is used by a cache prediction engine to select data blocks for caching to one or more of the cache devices.
