Abstract: A hybrid media storage architecture has a log-structured file system configured to control a plurality of different storage media organized as hybrid storage media that cooperate to provide a total storage space of a storage system. The log-structured file system is configured to perform initial placement and migration of data, as well as fine-grain write allocation of the data, among storage space locations of the hybrid storage media to thereby improve the performance characteristics of the media. By defining and implementing heuristics and policies directed to, e.g., types of data, the file system may initially place data on any of the different media and thereafter migrate data between the media at fine granularity and without the need for manual enforcement.

Abstract: Data consistency and availability can be provided at the granularity of logical storage objects in storage solutions that use storage virtualization in clustered storage environments. To ensure consistency of data across different storage elements, synchronization is performed across the different storage elements. Changes to data are synchronized across storage elements in different clusters by propagating the changes from a primary logical storage object to a secondary logical storage object. To satisfy the strictest RPOs while maintaining performance, change requests are intercepted prior to being sent to a filesystem that hosts the primary logical storage object and propagated to a different managing storage element associated with the secondary logical storage object.

Abstract: Embodiments described herein are directed to a file system driven RAID rebuild technique. A layered file system may organize storage of data as segments spanning one or more sets of storage devices, such as solid state drives (SSDs), of a storage array, wherein each set of SSDs may form a RAID group configured to provide data redundancy for a segment. The file system may then drive (i.e., initiate) rebuild of a RAID configuration of the SSDs on a segment-by-segment basis in response to cleaning of the segment (i.e., segment cleaning). Each segment may include one or more RAID stripes that provide a level of data redundancy (e.g., single parity RAID 5 or double parity RAID 6) as well as RAID organization (i.e., distribution of data and parity) for the segment. Notably, the level of data redundancy and RAID organization may differ among the segments of the array.

Abstract: The data path in a network storage system is streamlined by sharing a memory among multiple functional modules (e.g., N-module and D-module) of a storage server that facilitates symmetric access to data from multiple clients. The shared memory stores data from clients or storage devices to facilitate communication of data between clients and storage devices and/or between functional modules, and reduces redundant copies necessary for data transport. It reduces latency and improves throughput efficiencies by minimizing data copies and using hardware assisted mechanisms such as DMA directly from host bus adapters over an interconnection, e.g. switched PCI-e "network". This scheme is well suited for a "SAN array" architecture, but also can be applied to NAS protocols or in a unified protocol-agnostic storage system. The storage system can provide a range of configurations ranging from dual module to many modules with redundant switched fabrics for I/O, CPU, memory, and disk connectivity.
