Abstract: A system and method for improving the management of data input and output (I/O) operations for Shingled Magnetic Recording (SMR) devices in a network storage system is disclosed. The storage system includes a storage controller that receives a series of write requests for data blocks to be written to non-sequential addresses within a pool of SMR devices. The storage controller writes the data blocks from the series of write requests to a corresponding sequence of data clusters allocated within a first data cache of the storage controller for a thinly provisioned volume of the pool of SMR devices. Upon determining that a current utilization of the first data cache's data storage capacity exceeds a threshold, the sequence of data clusters including the data blocks from the first data cache are transferred to sequential physical addresses within the SMR devices.

Abstract: A clustered network-based storage system includes a host server, multiple high availability system controller pairs, and multiple storage devices across multiple arrays. Two independent storage array subsystems each include a quorum drive copy and are each controlled by a HA pair, with remote volume mirroring links coupling the separate HA pairs. The host server includes a virtualization agent that identifies and prioritizes communication paths, and also determines capacity across all system nodes. A system storage management agent determines an overall storage profile across the system. The virtualization agent, storage management agent, quorum drive copies and remote volume mirroring link all operate to provide increased redundancy, load sharing, or both between the separate first and second arrays of storage devices.

Abstract: A system, method, and computer program product for the provision of an elastic snapshot repository is disclosed. A snapshot repository with a particular size stores snapshot images. As the used capacity of the snapshot repository exceeds a predetermined threshold, another volume is added from a pool of available volumes. When the used capacity of the snapshot repository is at, or falls below, a lower threshold, a second snapshot repository is created. The schedule associated with the first snapshot repository is transferred to the second snapshot repository. The snapshot images in the first snapshot repository remain available to meet a minimum history requirement. New snapshot images are stored to the second snapshot repository until there are enough snapshot images in the second snapshot repository, alone, to meet the minimum history requirement. The first snapshot repository is deleted in response and the associated volumes released to the pool.

Abstract: Systems and methods that result in a stable storage system are provided. In the storage system, the latency spikes may be reduced when multiple volumes are aggregated into transfer sets according to system characteristics. The storage system transfers ownership of volumes in each transfer set as a single transaction. In the storage system, connectivity between the host and the storage controller is re-established based on the connectivity in a physical transport layer and a single path. In the storage system, pre-mature failback is also avoided when ownership of volumes is transferred back to a preferred storage controller when the same number of paths existed between the host and the preferred storage controller before and after a failover operation. Further, the storage system generates connectivity reports that display connectivity paths between hosts, storage controllers, and volumes.

Abstract: A method, a computing device, and a non-transitory machine-readable medium for performing a multipath selection based on a determined quality of service for the paths. An example method includes a host computing device periodically polling a storage system for path information including an indication of a recommended storage controller. The host computing device periodically determines a quality of service information corresponding to a plurality of paths between the host computing device and a storage volume of the storage system, where at least one of the plurality of paths including the recommended storage controller. The host computing device identifies a fault corresponding to a path of the plurality of paths that routes I/O from the host computing device to the storage volume. The host computing device re-routes the I/O from the path to a different path of the plurality of paths, where the different path is selected for the re-routing based on the quality of service information and the path information.

Abstract: Systems and methods that select a cache flushing algorithm are provided. A stripe that spans multiple storage devices and includes a plurality of segments is provided. The stripe also includes dirty data stored in a picket-fence pattern in at least a subset of segments in the plurality of segments. A memory cache that stores data separately from the plurality of storage devices and a metadata cache that stores metadata associated with the dirty data are also provided. A cache flushing algorithm is selected using the metadata. The selected cache flushing algorithm flushes data from the memory cache to the stripe.

Abstract: A system, method, and computer program product is described for providing dynamic enabling and/or disabling of protection information (PI) in array systems during operation. A storage system receives a request to transition a volume from PI disabled to PI enabled during regular operation. The storage system synchronizes and purges the cache associated with the target volume. The storage system initiates an immediate availability format (IAF-PI) process to initialize PI for the associated data blocks of the volume's storage devices. The storage system continues receiving I/O requests as the IAF-PI process sweeps through the storage devices. The storage system inserts and checks PI for the write data as it is written to the storage devices. The storage system inserts PI for requested data above the IAF-PI boundary and checks PI for requested data below the IAF-PI boundary. The transition remains an online process that avoids downtime.
