  • Method and system for facilitating communication between a host and downstream devices in a data storage system
    Patent number: 8639864
    Abstract: A diplex FPGA is utilized to fan out a single high speed host universal asynchronous receiver transmitter (“UART”) channel into a number of diplex UART channels. The diplex FPGA includes a microprocessor, memory, a host UART and a number of diplex UARTs. In operation, the microprocessor polls each of the UARTs in a “round robin” manner and accepts packets from the host UART for transmission downstream and from the diplex UARTs for transmission upstream.

  • Enclosure configurable to perform in-band or out-of-band enclosure management
    Patent number: 7716315
    Abstract: Described is an enclosure that is configurable to perform either in-band or out-of-band enclosure management. The enclosure includes a midplane, a processor blade, and a management module. The processor blade has program code for collecting management information from other components in the enclosure. If the enclosure is configured for in-band enclosure management, the processor blade executes the program code to collect the management information. If the enclosure is configured for out-of-band enclosure management, the management module is configured to execute program code for collecting the management information instead of the processor blade.
