A system and method are provided for processing storage commands between a host and a target. The system includes a first line card, a system card, and a second line card. The storage command that is issued from the host is received by the first line card. The first line card determines whether or not it can process the request by itself and, if so, forwards the storage command to the second line card for forwarding (and eventual processing) by the target. If the first line card cannot process the storage command by itself, it forwards the storage command to the system card for additional processing. The revised storage command is issued from the system card to the first line card. The first line card then issues the revised storage command to the second line card for eventual processing by the target.

System and method for scalable switch fabric for computer network

A cache system and method in accordance with the invention includes a cache near the target devices and another cache at the requesting host side so that the data traffic across the computer network is reduced. A cache updating and invalidation method are described.

Caching system and method for a network storage system

A system and method for providing flow control for a computer network is disclosed. In one embodiment of the present invention, buffer-to-buffer credit flow control is implemented to limit the amount of data a port may send based on the number and size of the frames sent from that port.

Buffer to buffer credit flow control for computer network

Methods and devices supporting the management of a plurality of electronic devices and processing of update information for updating software and/or firmware in the electronic devices Prompting of users may be made using a language associated with the electronic device, and authorization to update an electronic device may be secured using a subscriber identity module

Device management in a network

A switch fabric system comprises a first chassis for receiving a plurality of line cards each having a plurality of ports and at least two switch fabric cards wherein each line card comprises a plurality of link ports for linking the line card with the switch fabric card Each switch fabric card provides a switching bandwidth The system comprises a management unit for managing the traffic on the switch fabric cards wherein the management unit removes the traffic from one switch fabric card if the one switch fabric card is to be removed while the other switch fabric card operates and transfers the traffic to the other switch fabric card

System and method for expansion of computer network switching system without disruption thereof

A processor capable of selecting between a write-back and a write-through mode of operation includes a bus interface unit for transferring information across the external bus. A local cache memory is coupled to the bus interface unit for storing information received from the bus interface unit. The processor also includes a control unit coupled to the cache memory and the bus interface unit. The control unit is operable to restart an interrupted operation from a point of interruption. A storage device coupled to the control unit stores a value corresponding to the point of interruption of the operation.
