Abstract:
One or more techniques and/or systems are provided for generating a macroscopic cluster view of storage devices, as opposed to merely an isolated view from an individual node. For example, nodes within a node cluster may be queried for storage device reports comprising storage device information regarding storage devices with which the nodes are respectively connected (e.g., I/O performance statistics, path connections, storage device attributes, status, error history, etc.). The storage device reports may be aggregated together to define one or more storage device data structures (e.g., a storage device data structure comprising one or more tables that may be populated with storage device information). In this way, the cluster view may be generated based upon querying one or more storage device data structures (e.g., an error cluster view, a storage device cluster view, a node summary cluster view, etc.).

Abstract:
A storage controller receives data from a host. The data is provided to a storage stack on the storage controller. The storage stack can perform deduplication, compression or file layout operations on the data, which is then written to a first storage unit coupled to a first port of the storage controller. The storage controller determines whether a second port of the first storage controller is configured as a remote port. In response to determining that the second port is configured as a remote port, the data is also provided to a pass-thru stack on the first storage controller. The pass-thru stack performs protocol conversion on the data and writes the data to the second port on the storage controller.
Abstract:
A clustered storage environment can distribute responsibility for naming virtual disks to nodes of the clustered storage environment. The clustered storage environment maintains a list of names in a structure that is visible to cluster member nodes responsible for naming the virtual disks. As the cluster member nodes discover mass storage devices (e.g., storage arrays) in the clustered storage environment, the nodes determine identifiers of the mass storage devices. For each mass storage device, the nodes use the mass storage device identifier to establish a namespace for virtual disks of the corresponding mass storage device. The nodes can then provide consistent, exclusive names for the virtual disks throughout the cluster that are manageable names.

Abstract:
A system and method for uniquely identifying a storage device among an array of storage devices of a storage system is provided. In some embodiments, a storage device of the storage system is identified. The storage device may currently lack a name or may have an invalid name. A shelf identifier of a storage device shelf in which the storage device is installed is determined. A stack identifier associated with a connection of the storage device is also determined. The storage system constructs a device name for the storage device based on the shelf identifier and the stack identifier. In some such embodiments, a bay in which the storage device is installed is determined, and the device name is further based on an identifier of the bay. The device name may include the stack identifier, the shelf identifier, and/or the identifier of the bay.
Abstract:
A method, non-transitory computer readable medium, and device that associates a storage error with a specific array includes receiving a request to display one or more storage errors associated with one or more physical storage mediums within a storage device. An error cache associated with each of the one or more physical storage mediums within the storage device is scanned to identify the one or more storage errors reported by at least one of the one or more physical storage mediums within the storage device. Based on one or more business rules, the identified one or more storage errors are checked whether they are in the required format. An error list comprising the identified one or more storage errors and their corresponding one or more physical storage mediums is provided when the identified one or more storage errors are determined to be in the required format.
