  • Method and apparatus for dividing a single serial enclosure management bit stream into multiple enclosure management bit streams and for providing the respective bit streams to respective midplanes
    Patent number: 8473655
    Abstract: A controller is provided that receives a single enclosure management (EM) serial bit stream from an expander or other device and divides the EM serial bit stream into multiple EM serial bit streams for delivery to multiple respective midplanes or backplanes. In this way, a separate EM serial bit stream is provided to each midplane or backplane without having to increase the number of ports that are available on the expander or other device that interfaces with the backplane or midplane.

  • Reliable and efficient data transfer over serial port
    Patent number: 7657650
    Abstract: A system and method of reliable and efficient data transfer over serial port are disclosed. In one embodiment, a method of communicating data to a headless system over a communications medium includes transmitting data over the communications medium, ceasing transmitting data over communications medium in response to detecting a change in a status of a pin (e.g., a pin of a Modem Status Register, a Clear to Send, a 5th bit of the Modem Status Register, etc.) on the communications medium, and repeating the transmitting data over the communications medium in response to receiving a request to resend the data. The method may include transmitting a size of the data (e.g., a 2 byte value) over the serial port.
