Abstract: In one embodiment, an apparatus includes n electrical communication channels, m optical communication media interfaces, and a plurality of muxes. The plurality of muxes are configured to receive an information stream. The information stream is carried over the n electrical communication channels and the m optical communication media interfaces. The plurality of muxes are further configured to transform the information stream from v virtual lanes. Each virtual lane includes a plurality of data blocks from the information stream and an alignment block, wherein v is a positive integer multiple of the least common multiple of m and n, v is greater than n, and n is equal to m.

Abstract: An apparatus is provided that includes n communication channels, and m communication media interfaces, and v virtual lanes. V is a positive integer multiple of the least common multiple of m and n. An information stream is transferred into data and alignment blocks striped across all of the v virtual lanes, the blocks being communicated from the virtual lanes onto the communication channels. The blocks are received on the communication channels. Each of the communication channels transmits a different portion of the blocks striped across all of the v virtual lanes.In more particular embodiments, v>=n>=m. The communication media interfaces can be electrical and optical. Each of the communication channels can include a SerDes interface operating at least 5 Gigabits per second. Furthermore, each of the m communication media interfaces is configured to transmit a different stream of information over a single optical fiber.

Abstract: Techniques for temperature control for multiple dies in an element. A temperature of a first die is measured, in an element comprising the first die and a second die. The second die includes at least a portion of a controller. The temperature of the first die is changed by adjusting activity, from the second die to the first die, based on a target temperature for the first die and the measured temperature for the first die.

Abstract: Symbol multiplexing Physical Medium Attachment (PMA) may be provided. A plurality of first lanes may be received and then Alignment Markers (AMs) from the plurality of first lanes may be used to determine symbol boundaries and identify the plurality of first lanes. Next, groups of the plurality of first lanes may be de-skewed and checkerboard patterns in the plurality of first lanes may be undone. Then the plurality of first lanes may be symbol-wise multiplexed to a plurality of second lanes. The plurality of second lanes may then be sent.

Abstract: Embodiments herein describe coupling traditional fan and shaper control along with aggregated knowledge of the temperature history of a hardware device to optimally manage the temperature of the hardware device to preserve its expected life while also providing the lower power, best performing solution possible. In one embodiment, a cooling application manages the expected life by trading off performance and power versus temperature to achieve a desired (or accepted) lifetime. In one embodiment, the cooling application calculates a historical temperature value for the hardware device which is then used to determine the expected life of the hardware device.
