An agent in a storage area network communicates with a management entity in the storage area network to discover a group of resources in the storage area network controlled by the management entity. In response to discovering the group of resources, the agent associates member resources (e. g. , and their respective names) of the group of resources to a corresponding group identifier to which the member resources belong. The agent reports i) the corresponding group identifier and ii) the member resources of the group of resources controlled by the management entity to a management control center that assigns one of multiple agents in the storage area network to manage the group of resources based on communications with the management entity. After a step of assigning, the management control center can initiate an assigned agent to control the group of resources.

An agent of a storage area network generates a first checksum value for a first set of zone configuration data used to at least initially configure the storage area network. At a later time, after a potential change to the first zone configuration data of the storage area network, the agent generates a checksum value based on current zone configuration data presently used to configure the zone in the storage area network. The agent then compares the first checksum value and the second checksum value to identify whether there has been a change to the first zone configuration data. That is, if the first checksum value does not equal the second checksum value, the agent flags that there has been a change to zone configuration data of the storage area network. Users can control behavior of zoning importation and activation depending on whether current zone configuration data has been changed.

A management control center communicates with multiple agents in a storage area network. On behalf of the management control center, the agents communicate with a switch resource management entity that maintains configuration information about resources such as a group or groups of switches in the storage area network. Based on a chain of communications from the management control center through the agents to the remote management entity, the management control center can indirectly learn about a configuration of switch resources in the storage area network. The agent utilizes a calculated current load value (e. g. , a value indicating a relative burden placed on the remote management entity to service the forwarded set of requests) to selectively forwards requests to the switch resource management entity. This technique ensures that the switch resource management entity is not overwhelmed by a task of servicing too many requests at the same time.

Mechanisms and techniques provide a management application providing an enterprise storage area network application programming interface for managing elements in a storage area network. The management application initializes a plurality of access wrappers that each defines operations for management of a respective class of elements operating within the storage area network. The management application provides, to a management client, connection data associated with a specific element associated with one of the plurality of access wrappers. The connection data identifies connection data parameters for performing management of the specific element in the storage area network. The management application receives at least one generic management command for the specific element. The generic management command includes at least a portion of the associated connection data for the specific element. The management application operates at least one access wrapper to translate the at least one generic management command into an operation of at least one vendor-specific command to manage the vendor specific element in the storage area network.
