Abstract:
Data-center networks have leveraged Ethernet’s decade approach, where rates traditionally differed by a factor of 10 between server and network connections. This changed with the introduction of 40GbE to a factor of 4, notably in Cloud-scale data-centers that used 10Gb/s for server IO and 40Gb/s for networking. With the introduction of 100GbE, the industry has invested in 25Gb/s electrical signaling and data-centers are looking to use 25G/s for server IO and 100Gb/s for networking. The recent approval of the IEEE 802.3 25GbE Study Group underscores this x4 factor between server and networking rates. This presentation will consider the potential implications of the next serial rate of electrical signaling and its application to data-center networking; and ponder what it could mean for Ethernet’s future and the rates it will support.
