Abstract: A bus-to-bus adapter (20) is provided for coupling the input/output bus of a first data processor (21) to the input/output bus of a second and different type of data processor (22). The adapter enables the transfer of data and messages from the first processor to the second processor and vice versa. The adapter includes a buffer storage unit (34) and control logic (39) for enabling multiple data buffers to be provided for enabling multiple independent data transfer operations to be performed in a concurrent manner. The control logic also includes a mechanism for allowing the reading out of data from a data buffer to begin before such data buffer has received all of its incoming data. The adapter further includes a programmable service time allocation mechanism for limiting message service time relative to data transfer service time and for providing different amounts of data transfer service time for different ones of the multiple data buffers.

Abstract: Techniques are disclosed for managing a switch fabric. In one embodiment, a server system is provided that includes a midplane, one or more server cards, switch modules and a management controller. The midplane may include a fabric interconnect for a switch fabric. The one or more server cards and the switch modules may be operatively connected to the midplane. The switch modules may be configured to switch network traffic for the one or more server cards. The management controller may be configured to manage the switch modules via the fabric interconnect.

Abstract: In a switching system (fig. 1) comprising server card â bladesâ (104, fig. 1 & 202, fig. 6), a midplane 123 is connected to switch modules 4201-3 on different server cards thus providing a fabric interconnect for a switch fabric under the operation of a management controller (1604, fig. 16) which updates and monitors the switch modules, and informs others when one fails. Switch modules may be replaced (â hot swappedâ ) without restarting the system or fabric.
