Abstract: Provided are a method, system, and program for processing a transmission from a first device to a second device. An identification transmission is received including an interface address from the first device. A determination is made as to whether the identification transmission indicates a recognized vendor identifier. An interface address of a third device is returned to the first device in response to determining that the identification transmission includes one recognized vendor identifier, wherein the third device relays transmissions between the first and second devices.

Abstract: A method according to one embodiment may include operating an integrated circuit in a selected mode of operation. The integrated circuit may include first circuitry and second circuitry. The first circuitry may be capable of performing at least one operation including, at least in part, generating check data based at least in part upon other data, regenerating the other data based at least in part upon the check data, and/or determining locations of the check data and the other data in storage. The second circuitry may be capable of controlling, at least in part, at least one interface to transmit from and/or receive at the integrated circuit the check data and/or the other data. Depending at least in part upon the selected mode of operation, the first circuitry may be either enabled to perform or disabled from performing the at least one operation.

Abstract: An apparatus according to one embodiment may include an integrated circuit. The integrated circuit may include a processor and a switch. The switch may comprise one or more ports capable of being coupled to one or more segments external to the switch. The processor may be capable of issuing to the switch one or more commands indicating, at least in part, one or more protocols via which the one or more ports are to communicate and/or one or more forwarding characteristics of the switch. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.

Abstract: An apparatus according to one embodiment may include an integrated circuit. The integrated circuit may include a processor, a bridge, and circuitry capable of coupling the bridge and the processor to a first bus and to a second bus. The first bus may be compatible with a first bus protocol, the second bus may be compatible with a second bus protocol, and the first and second bus protocols may be different from each other. The bridge may be capable of, in response at least in part to a request from the processor, preventing a command received at the bridge via the first bus from being forwarded from the bridge to the second bus. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.

Abstract: An apparatus according to one embodiment may include an integrated circuit. The integrated circuit may include a processor and a switch. The switch may include at least one port capable of being coupled to at least one external communication link. The processor may be capable of issuing a request to the switch to request that the switch block forwarding via the at least one port of a command received by the switch. The switch may be capable of issuing to an issuer of the command, in response at least in part to receipt by the switch of the command, a response indicating absence of the at least one port from the switch. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.

Abstract: A method according to one embodiment may include transmitting a frame from a transmitting device to a receiving device via a communication network of a data storage system, enabling an encoding operation of the transmitting device to encode decoded data into encoded data and transmitting the encoded data in the frame via the communication network if the receiving device has a decoding operation capable of decoding the encoded data into the decoded data, and disabling the encoding operation and transmitting the decoded data in the frame via the communication network to the receiving device if the receiving device does not have the decoding operation capable of decoding the encoded data into the decoded data. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.

Abstract: A method according to one embodiment may include operating an integrated circuit in a selected mode of operation. The integrated circuit may include processor circuitry and interface circuitry. The processor circuitry may include a plurality of processor cores. The interface circuitry may be capable of communicating in accordance a plurality of different protocols.

Abstract: Provided are a method, adaptor, system, and program for receiving a transmission at one of multiple connections. Information is maintained on storage interconnect architectures and transmission characteristics, wherein the storage interconnect architectures have different transmission characteristics. At least one transmission characteristic of the received transmission is determined and a determination is made from the information of the storage interconnect architecture associated with the determined transmission characteristic. The information on the determined storage interconnect architecture is used to process the transmission and determine a transport layer for the received transmission, wherein there is one transport layer for each supported transport protocol. The transmission is forwarded to the determined transport layer.

Abstract: The state of cached data may be modified without performing a tag comparison. Each cache line includes at least one attribute bit and at least one state bit. A processor issues an instruction requesting modification of the state of all cache lines associated with an attribute specified by the instruction. Qualifying logic modifies the state of a cache line as a function of the attributes stored in the cache line and the attribute specified by the instruction.
