  • 40 and 100 Gigabit Ethernet: an Imminent Reality
    WHITE PAPER 40 and 100 Gigabit Ethernet: An Imminent Reality 40 and 100 Gigabit Ethernet: An Imminent Reality Many of today’s data centers are running 10 Gigabit Ethernet (GbE) over both optical fiber and balanced twisted-pair copper cabling in their backbone infrastructure where large numbers of gigabit links aggregate at core devices. As more edge devices; like servers and storage equipment, continue to move to 10 GbE, the next natural progression is for the network core to require even faster connections within the data center. Fortunately, there is a solution that is now an imminent reality. Standards have been in development since 2008, and the Institute of Electrical and Electronics Engineers (IEEE) will soon release the 802.3ba standard that will support data rates for 40 and 100 GbE over optical fiber cabling. Both cable and connectivity solutions capable of supporting these speeds already exist, and vendors are in the process of developing active equipment. Now is the time to migrate data center cabling infrastructures to support this imminent technology. 40 and 100 Gigabit Ethernet: An Imminent Reality Key Market Drivers 100 90 From storage and IP traffic growth to the advancement 35% CAGR in Storage Capacity of technology across many market sectors, the drivers 80 that moved data transmission speeds from 1 GbE to 68 10 GbE over the past decade are now expanding as 60 forecasted, creating the need for 40 and 100 GbE. 49 Petabytes 40 37 10 GbE Growth 28 20 20 While the global Ethernet switch market experienced overall decline in 2009, the migration from 1 to 10 0 GbE continued in data centers across the world.

In the mid- 1980s, IBM unveiled a competing network technology called Token Ring. You’ll get the complete discussion of Token Ring in the next chapter, but it’s enough for now to say that Token Ring used a physical star topology.

    DATA CENTER BANDWIDTH SCENARIOS Scott Kipp [email protected] March 2014 1 Opinions expressed during this presentation are the views of the presenters, and should not be considered the views or positions of the Ethernet Alliance. 2 From Applications to Data Centers • Applications, servers, storage, networks and data centers have varied compute, bandwidth and availability requirements • Intel has 150 different processors for server market • Servers vary from <1/10U to multiple racks • Switch ports range from 100 Mb/s to 100 Gb/s • Storage devices vary from 10GB to 100s of Petabytes • 100 servers to 100,000 servers in a data center • Because of the varied requirements and capabilities, it is difficult to talk about anything specific without losing something • I’ll try anyway… 4/4/2014 3 Starting with Servers Multiple Server Categories • Microservers • Blade Servers 95% of Volume, Cray X-ES – 46 Microservers • <1U Servers Not revenue • 1-2U Servers • 4-12U Servers • Rack and multi-rack Servers IBM Mainframe 4/4/2014 4 Bandwidth Requirements of Servers ~10M servers ship every year, >95% are x86 GbE 10GbE 40GbE 100GbE 10M Servers Servers Servers Servers Servers that need less than 4Gb/s use Mega- multiple GbE NICs Data 5M # Serversof Server Center Server Bandwidth Bump Bandwidth Demand Demand in in 2014 2019 0 100M 1G 4G 10G 40G 100G Source: Multiple Bandwidth per Server (b/s) Sources and Estimates 4/4/2014 5 10GbE and 40GbE Server Ports 10GBASE-T will Most 10GbE Servers continue to ramp but 40GbE servers will connect with SFP+ or not used in
