  • Multi-protocol controller that supports PCIe, SAS and enhanced Ethernet
    Patent number: 7917682
    Abstract: SAS over Enhanced Ethernet (SOE) controllers that integrate SAS and Enhanced Ethernet to perform a conversion between SAS and Enhanced Ethernet are disclosed. A central intelligence block can be employed to perform the mapping between SAS and Enhanced Ethernet. The SOE controller can include one or more Enhanced Ethernet Interfaces, one or more SAS interfaces, and a PCIe interface. The SOE controller can direct the I/O requests presented on one interface to another interface after performing some basic operations on the I/O requests, including protocol conversion. The SOE controller can include an intelligence mechanism for identifying the appropriate output ports for routing the I/O requests and redirecting them accordingly. In the case of routing I/O requests over Enhanced Ethernet, the SOE controller can perform SAS protocol conversion to map outgoing I/O requests into Enhanced Ethernet frames suitable for transmission over the Enhanced Ethernet network.
