International Classification:
G06F 13/00, G06F 13/20, G06F 13/36
US Classification:
710104, 710311, 710313, 710314, 710316
Abstract:
Described are electronics systems and methods for distributing a limited number of lanes of a PCI Express-based processor (CPU) module among a plurality of PCI Express-based I/O modules with which the CPU module is in communication. The CPU module receives a code from each I/O module over a sideband interface between that I/O module and the CPU module. The coded signal represents a link-width capability of the I/O module. The CPU module is configured to allocate a link width to each I/O module based on the fixed number of lanes and the link-width capability as represented by the coded signal received from that I/O module. The link between CPU module and each I/O module is trained in accordance with the link width allocated to that I/O module.

International Classification:
G06F 3/00
US Classification:
710 1, 710 15, 710 18, 710 19
Abstract:
Described is an electronics system and method for marking and faulting I/O ports of an I/O module in the electronics system. Each I/O port has an associated light-emitting system that is capable of emitting a plurality of different colors. At least one color is blinked at a first rate to produce a first status indicator for the I/O port. Each color of the different colors is alternately blinked at a second rate to produce a second status indicator for the I/O port. One of the status indicators is for marking the I/O port and the other status indicator is for faulting the I/O port. In one embodiment, the light-emitting system includes a plurality of differently colored LEDs. In another embodiment, the light-emitting system includes only one multicolor LED. Various I/O technologies including Fiber Channel, Fiber Connectivity, Ethernet, serial attached SCSI, IPsec, Infiniband, and iSCSI, can implement marking and faulting.

US Classification:
709220000, 709227000
Abstract:
System availability is managed. It is determined that a data communications link has been established and that the data communications link is less than fully functional. Communication is performed across the data communications link to a device to configure the device for the data communications link. The device is caused to re-establish the data communication link based on the results of the configuring.
