    摘要： 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.

    摘要： A system and method for connectivity-aware assignment of volumes among the storage controllers of a storage system is provided. In some embodiments, during a discovery phase, a connectivity metric is determined from a device discovery command. The connectivity metric is recorded into a data structure that identifies a plurality of hosts and a plurality of storage controllers of a storage system. In response to the determining of the connectivity metric, a storage controller ownership of a first volume is changed to improve connectivity between a host of the plurality of hosts and the first volume. In some such embodiments, a storage controller ownership of a second volume is changed to balance load among the plurality of storage controllers, and the discovery phase is, in part, a response to the change in the storage controller ownership of the second volume.
