BLADE SERVER SYSTEM WITH AT LEAST ONE RACK-SWITCH HAVING MULTIPLE SWITCHES INTERCONNECTED AND CONFIGURED FOR MANAGEMENT AND OPERATION AS A SINGLE VIRTUAL SWITCH

摘要

A rack-switch (10) including a rack and a plurality of blade server chassis (58-1 to 58-n) within the rack. Each blade server chassis (58) has a plurality of server blades (22) in communication with at least one switch (14). Each switch (14) includes a plurality of external ports (22). At least two of the external ports (22) of each switch (14) ar inter-switch link (ISL) ports (22). The rack-switch (10) also includes a plurality of inter-switch links. Each inter-switch link (22) electrically connects one ISL port of one of the switches (14) to one ISL port (22) of another of the switches (14). The plurality of inter-switch links (22) interconnects the switches (14) such that the switches are daisy chained hi a loop. The inter-switch links (22) convey Ethernet packets representing server-to-server communications between server blades (22) of different blade server chassis (58).
