Abstract:
A method, system, and computer program product for a data propagation platform and applications of same is described. The data propagation platform provides various storage functions. According to an embodiment, the factories of the data propagation platform create and implement device modules. Device modules perform operations on encapsulated messages formed from data and commands, such as device operation commands and data from storage device read/write operations. Device modules are formed into device chains. Device chains are able to perform various tasks as a sum of device modules. In embodiments, device chains are layered and built on each other.
Abstract:
A system for allocating storage resources in a storage area network is described. A logical unit number (LUN) mapper receives at least one storage request parameter and maps the storage request parameters to at least one physical LUN. The LUN mapper includes at least one LUN map. The storage request parameters include a host id parameter, a target LUN parameter, and a target host bus adaptor (HBA) parameter. The LUN mapper uses the host id parameter to select the one of the LUN maps that corresponds to the host id parameter. The LUN mapper applies the target LUN parameter and the target HBA parameter to the selected LUN map to locate the physical LUN(s) stored in the selected LUN map. The LUN mapper issues the received read/write storage request to at least one storage device that houses the physical LUN(s). The one or more storage devices are located in the storage area network.
