We’re going to see a whole lot more of this trend. Innovation doesn’t die in the age of merchant silicon, it just takes new forms. In the the Cisco/Insieme Nexus 9000, they have divided the resources of the line-card and fabric Trident2 ASICs in very different and clever ways to get the most from those small table sizes. SummaryĪrista doesn’t need to use this particular trick any more but I love the approach of innovating beyond fixed constraints.

Although this seems like overkill for a single-RU box, it is a great strategy if you have fabric programming experience in your software team. There are many other multi-ASIC challenges here such as keeping the 元 and L2 tables synced in the front-facing ASICs. In order to simply inter-ASIC routing, the front-facing ASICs will most likely add an destination-ASIC tag onto the packet to simplify the fabric-ASIC lookup logic. Arista have used a linecard-and-fabric architecture borrowed from chassis switches, but have collapsed that architecture into a single standalone switch. Note that the architecture has changed too. I was a little surprised that so many ASICs were needed. Whoah, you need six 24-port ASICs to double the front panel port-count in a non-blocking switch. This solution won’t work, so let’s look at the final solution. Worse still, you have 3:1 oversubscription on your interconnect. You have only 36 front-panel ports and you need 48. Okay, that looks a bit better, but it still doesn’t meet requirements. To interconnect them you could redeploy some of the front-panel ports as inter-ASIC ports, as per the diagram below. So… how many do you need? Deploying two 24-port ASICs does double your total port-count, however you will end up with two logical switches instead of one. The obvious choice here is to deploy more 24-port ASICs. (simplified diagram to left).įor the 7148SX, Arista needed to build a 48-port non-blocking switch from 24-port ASICs.

But you don’t stop innovating just because you’re using standardised building blocks. When Arista were developing the 7100 series switches they chose the 24 x 10Gbps Intel Fulcrum FM4000 ‘Bali’ ASIC. The down side is that Arista is limited by the port-count of the current generation of ASICS. Using merchant silicon solves a raft of problems for Arista. Trident2: 108 x 10Gbps (108 x 10G MACs – can handle 1.2Tbps using some ports at 40G).Īrista Networks’ strategy is to use best-of-breed merchant-silicon switch ASICS in their switches rather than developing custom ASICS in house.The Intel Fulcrum ASIC evolution isn’t shown here but looks very similar. The list below shows the 10Gbps port density evolution of the Broadcom StrataXGS product line.

Almost all TOR switches use a single switch ASIC and the industry demanded port-density on a single ASIC, and the manufacturers delivered. This means you get non-blocking port-to-port throughput within the switch ASIC at the line rate of the front panel ports.
