Storage gateway provisioning and configuring
Storage gateway provisioning, configuration, and management functions provide mechanisms to specify and manage parameters and operations associated with storage gateways. The parameters may include any combination of VLAN topology, zoning behavior, LUN masking, bandwidth, and priority. The parameters may also include path information describing initiator to target associations, enabling load-balancing aggregations and multipathing redundancy. Parameters may be specified at relatively low-levels, describing specific HW elements, or may be specified at relatively high-levels, describing desired bandwidth and redundancy requirements, with SW determining low-level HW assignments. Configuration and management functions enable dynamic modification of storage gateway parameters (such as bandwidth between selected initiator and target pairs). Management functions also enable dynamic switchover from a primary path to a secondary path with respect to a storage device.
