A topology of storage nodes coupled to a network to provide storage resources to clients coupled to the network is described. A common transport agent (CTA) comprises a common communication interface with each of the storage nodes. The common communication interface with each storage node may be independent of any particular input/output format to be used in storing data in or retrieving data from a storage medium associated with the storage node. The CTA may also comprise a communication interface with the network which is independent of any particular network protocol to transmit data over the network.

Network abstraction of input/output devices

An embodiment includes retrieving performance monitor data from an I/O processor. A performance monitoring driver coupled to a performance monitoring unit may be registered as a private driver with a real time operating system of the I/O processor. Events within the I/O processor may be selected on which to gather data. The selected events may be sent as a message request to the real time operating system. The message request may be translated into the appropriate parameters based on a set of private group parameters that may be accessible by the real time operating system. The message request may be sent as a translated request to the performance monitoring unit. The pieces of data requested by the translated request may be returned to the performance monitoring driver. The pieces of data then may be sent to a location specified in the message request.
