An internal common slot battery backup unit (CSBBU) is provided that can be placed in a network device's power supply unit (PSU) slot. The CSBBU has the same features of a PSU and communicates with other PSUs in the network device in order to determine when it should supply power to the networking device and when it should be in a recharging state.

Common slot battery backup unit for network devices

A method and apparatus are described to provide shared switch and cache memory. The apparatus may comprise a message switch module, a cache controller module, and shared switch and cache memory to provide shared memory to the message switch module and to the cache controller module. The cache controller module may comprise pointer memory to store a plurality of pointers, each pointer pointing to a location in the shared switch and cache memory (e.g., point to a message header partition in the shared switch and cache memory). If there is a corresponding pointer, a memory read response may be sent to the requesting agent. If there is no corresponding pointer, a write data request may be sent to a corresponding destination agent and, in response to receiving the requested data, a pointer to the stored data in the pointer memory may be provided.

Shared memory message switch and cache

In particular embodiments, there are provided methods and apparatus including receiving one or more Infiniband signal streams, de-serializing the received one or more Infiniband signal streams to generate a corresponding one or more parallel data streams, de-serializing further including selectively adding or deleting a control symbol associated with a quiescent period of the one or more received signal streams, time-division multiplexing the generated one or more parallel data streams, and serializing the time division multiplexed one or more parallel data streams.

Multiple infiniband ports within a higher data rate port using multiplexing

A data storage system comprises an InfiniBand port, a fibre channel port, and a controller. The InfiniBand port is operable to connect the data storage system to a computer, and the fibre channel port is operable to connect the data storage system to one or more fibre channel storage devices. The controller is operable to receive an InfiniBand boot request from a computer system via the InfiniBand Port, and to connect the computer system to the one or more fibre channel storage devices via the fiber channel port such that the controller is operable to map an InfiniBand boot request from the computer system to a fibre channel target.

InfiniBand boot bridge with fibre channel target

Various embodiments provide methods and systems operable to receive a work queue pair from one of a plurality of host nodes, to scan the work queue pair for known data formats corresponding to one of a plurality of transport protocols, to optionally convert the work queue pair to produce a standard work queue pair data format, to add the work queue pair to a scheduler queue for a virtual host channel adapter (HCA) scheduler, and to update a context associated with the work queue pair.

Multiple context single logic virtual host channel adapter supporting multiple transport protocols

Various embodiments provide methods and systems operable to receive a work queue pair from the host application, to add the work queue pair to a scheduler queue for a virtual HCA scheduler, to update a context associated with the work queue pair, to create at least one data packet corresponding to the work queue pair, and to send the at least one data packet to at least one of a plurality of target nodes via at least one of a plurality of data channel ports.

Multiple context single logic virtual host channel adapter

A bridge comprises an InfiniBand channel adapter, a fiber channel adapter, a command path, and a data path. The command path is coupled to the InfiniBand channel adapter and the fiber channel adapter; and the command path is operable to receive commands from a first of the InfiniBand and fiber channel adapters, to process the received commands, and to transmit the processed command to the other of the InfiniBand and fiber channel adapters. The data path is coupled to the InfiniBand adapter and fiber channel adapter, and is operable to transfer data from the first of the InfiniBand and fiber channel adapters to the other of InfiniBand and fiber channel adapters.

Infiniband/fibre channel bridge architecture

A bridge comprises an InfiniBand port, a fiber channel port, a cut-through data path coupled to the InfiniBand port and fiber channel port comprising a data buffer path operable to store data, and a message control path operable to decode and encode message headers.
