Abstract

Disclosed is a method and apparatus for supporting direct write access from many nodes of a multi-mode network to a file managed by a single node file system. The network includes first and second nodes coupled to each other via a first communication link, and a peripheral data storage device coupled to the first and second nodes via a second communication link. In one embodiment, the method includes the first node receiving data. The first node transmits a first message to the second node via the first communication link in response to the first node receiving the data. A software module such as a single node file system, executing on the second node, allocates storage memory of the peripheral data storage device for the data received by the first node in response to the second node receiving the first message. The first node writes the data to the allocated storage memory via the second communication link such that the data is written to the allocated storage memory without the data first transmitting through the first communication link.
