40 Gigabit Switch

40 gigabit ethernet 40gbe and 100 gigabit ethernet 100gbe are groups of computer networking technologies for transmitting ethernet frames at rates of 40 and 100 gigabits per second gbit s respectively.
40 gigabit switch. Each frame is directed to one of the 2 x fabric interface asics based on the lookup result contained in the fabric header. 40 gigabit ethernet and 10 gigabit ethernet ports the summit x770 model provides 32 x 40 gbe qsfp ports which can accept qsfp passive and active cables as well as qsfp transceivers. These technologies offer significantly higher speeds than 10 gigabit ethernet the technology was first defined by the ieee 802 3ba 2010 standard and later by the 802 3bg 2011 802 3bj. In migrating to 40 gigabit ethernet some networks will be able to use their current 10 gigabit ethernet switch chassis and just upgrade their line cards and transceivers.
802 3ba is the designation given to the higher speed ethernet task force which completed its work to modify the 802 3 standard to support speeds higher than 10 gbit s. Individual frames arrive at the fabric asic over one of the 2 x 40 gigabit ethernet switch fabric channels with a 32bytes fabric header which contains the lookup result from ingress stage.
