HOST BUS ADAPTER WITH BUILT-IN STORAGE FOR LOCAL BOOT-UP

摘要

A method of a storage area network (SAN) includes storing and communicating data received from a server at a host bus adapter via a bus controller of the adapter. In a case where the data is associated with an address corresponding to a default boot logical unit (LUN) of a non-volatile memory (NVM) of the adapter, the data is stored in the NVM. In a case where the data is not associated with an address corresponding to a boot LUN of the NVM, the data is communicated over the SAN. During power up of the adapter, in a case where it is determined that the NVM includes an image of an operating system, the adapter uses the bus controller to provide the server with information to select the NVM as a boot LUN for booting the operating system.

主权项

1. An adapter for a disk-less server in a storage area network, the adapter comprising:
a printed circuit board including an edge connector and a plurality of wire traces; a processor mounted to the printed board and coupled to one or more of the plurality of wire traces; a non-volatile memory controller mounted to the printed board and coupled in communication with the processor and the edge connector; a read-writeable non-volatile storage memory mounted to the printed circuit board and coupled in communication with the non-volatile memory controller, wherein the read-writeable non-volatile storage memory stores a stored operating system software to boot up the server; and a network communication controller mounted to the printed circuit board and coupled in communication with the processor and the edge connector, wherein the network communication controller couples the server in communication with a computer network and communicates information over the computer network using one or more data communication protocols; wherein the processor manages information communicated between the adapter and the computer network and between the read-writeable non-volatile storage memory and the server.
