Deployment example

The diagram below shows an example of non-blocking network fabric leveraging a 32 x 400G device con gured to o er 128 x 100G

ports, a simple 2-tier fabric is able to support up to 6144 servers across 128 leaf switches with a xed 3:1 oversubscription and

optimally deterministic bisectional performance. The following diagram shows each leaf connecting with 4 x 100GbE across the four

spine devices.

High Availability

The Arista 7050X4 series switches are designed for high availability from both a software and hardware perspective. Key high

availability features include:

• 1+1 hot-swappable power supplies and four N+1 hot-swap fans

• Color coded PSU’s and fans

• Live software patching

• Self healing software with Stateful Fault Repair (SFR)

• Smart System Upgrade (SSU)

• Multi-chassis LAG for active/active L2 multi-pathing

• 128-way ECMP routing for load balancing and redundancy
