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 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 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 method, a computing device, and a non-transitory machine-readable medium for replacing an unreadable sector in a storage system is provided. In some embodiments, the method includes identifying a sector from a plurality of sectors in a physical memory of a storage device in a storage system as an unreadable sector. An unreadable sector is a sector that includes data that had been corrupted and cannot be recovered from data in the storage system. In some embodiments, the unreadable sector is recovered by receiving a copy of a sector identified as the unreadable sector from a cloud storage, where the copy of the sector stores readable data and the cloud storage is a separate storage from the storage system. The method then includes replacing the unreadable sector with the copy at the sector at a memory location in the physical memory occupied by the unreadable sector.

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.
