Abstract:
1. A computer program product encoded in an non-transitory information storage medium and usable with a programmable computer switch domain processor to set the speed of a network interconnected with a system controller and a plurality of switch domains, wherein each of said plurality of switch domains comprises a switch domain processor and one or more information storage devices, comprising: computer readable program code which causes said programmable computer processor to set a signaling rate for a switch domain; computer readable program code which causes said programmable computer processor to receive an in-band query from said system controller for that switch domain's signaling rate; computer readable program code which causes said programmable computer processor to disconnect the switch domain from the network; computer readable program code which causes said programmable computer processor to determine main a signaling rate for that switch domain; computer readable program code which causes said programmable computer processor to reconnect the switch domain to the network; computer readable program code which causes said programmable computer processor to provide in-band the signaling rate for that switch domain; computer readable program code which causes said programmable computer processor to receive in-band from said system a first speed selection command specifying a first network speed; computer readable program code which causes said programmable computer processor to reset the signaling rate for the switch domain to said first network speed.
