Arista Networks introduced a 100+ Terabit switching and routing platform for cloud service provider and next generation enterprise data centers. The new Arista 7500R is being positioned as the industry's highest performance universal spine switch for data centers.
Arista believes that shifting traffic patterns inside the data center are best served with scalable two-tier active Leaf-Spine and single tier Spline architecture. The traditional core routing layer can be replaced with an Arista 7500R series-based spine for rapid re-convergence and network-wide resilience between data centers and to the Internet. The Arista 7500R Series supports familiar MPLS functions allowing up to 13-labels deep packet lookup for programmatic control across the largest networks. Along with the state oriented architecture of Arista’s Network–wide Database NetDB and SDK, Arista EOS (Extensible Operating System) users can customize their own preferred path across the largest networks in the world, instead of relying on best-effort forwarding on the Internet.
The new Arista 7500R Series, which begin shipping in Q2, provides industry-leading 100GbE density and large table sizes in a single chassis. Key attributes:
- Chassis Fabric capacity of up to 115 Tbps
- Up to 432 wirespeed 100GbE ports in a choice of three form factors
- 288 Gigabytes of deep and smart packet memory for reliable packet transfers
- Virtual Output Queues (VoQ) for lossless forwarding
- Agile port speeds of 1/10/25/40/50/100GbE
- FlexRoute technology delivers up to 1 Million wire speed routes with MPLS, Segment Routing and EVPN (Ethernet Virtual Private Network) protocol support
- Programmable traffic engineering with up to 128,000 MPLS, GRE (Generic Routing Encapsulation), VXLAN (Virtual Extensible Local Area Network) and IP-in-IP tunnels
- Support for NEBS (Network Equipment Building System) compliance for Service Provider deployments
- Mix and Match across the wide selection of 7500E and 7500R series line-card options
- 36 x 100GbE QSFP - choice of 10/25/40/50/100GbE
- 36 x 40GbE with flexible combinations of 10GbE and up to 6 ports of 100GbE
- 48 x 10GbE SFP+ and 2 x 100G QSFP
“The 7500R is the highest performance switching and routing platform that supports the full Internet routing table, enabling a Universal Spine in cloud-scale networks,” said Andreas Bechtolsheim, Arista’s Chairman and Chief Development Officer.
