In one embodiment of the present invention, a network adapter is provided that may be used in a network data storage system to permit data exchange among data exchanging devices and a data storage system input/output (I/O) controller. The network adapter may include a control interface and a control logic section. The control interface may be coupled to the controller. The control logic section may receive from the controller, via the control interface, a command, and may transmit to the controller, via the control interface, information concerning the operation of the network adapter. The control logic section may access, based upon the command from the controller, memory that may contain the information and an executable command to be supplied to other logic in the network adapter. The control interface may be identical to control interfaces in other (i.e., different) types of adapters that may be controlled by the controller.

Network adapter and method of using same

A data storage system wherein a host computer is coupled to a bank of disk drives through a system interface. The system interface includes a memory having a high address memory section and a low address memory section. A plurality of directors controls data transfer between the host computer and the bank of disk drives as such data passes through the memory. A pair of high address busses, comprising a plurality of bus high address bus segments, is in communication with the high address memory section and a pair of low address busses, comprising a plurality of low address bus segments, is in communication with the low address memory section. Each one of the directors is in communication with one of the pair of high address busses and one of the pair of low address busses.
