Description

The Arista 7280R2 DCS-7280SR2-48YC6-F is a fixed-configuration 1RU data centre switch router with 48 x 25GbE SFP ports and 6 x 100GbE QSFP100 uplinks, running Arista EOS. It delivers 3.6 Tbps of wire-speed throughput with deep packet buffers, making it well suited to leaf and spine roles that need large routing tables and microburst tolerance. This SKU ships with front-to-rear airflow and dual hot-swap AC power supplies.

The SFP ports run at 25G or 10G/1G in groups of four, while the QSFP100 ports support 100G, 50G, 40G, 25G and 10G modes. Wire-speed L2 and L3 forwarding, VXLAN bridging and routing, MLAG, VRF and up to 128-way ECMP support modern data centre fabrics. Arista EOS, CloudVision, Zero Touch Provisioning and LANZ microburst detection round out the operational toolset.

Features

- Virtual Output Queue (VOQ) architecture with deep packet buffers to eliminate head-of-line blocking
- SFP ports configurable at 25G or 10G/1G in groups of 4, with FC and RS FEC
- 100G QSFP ports support 6x100GbE, 24x25GbE, 6x40GbE or 24x10GbE modes
- Wire-speed L2 and L3 forwarding with 768K MAC addresses and 768K IPv4/IPv6 host routes
- 1.3M IPv4 and 1M IPv6 unicast LPM routes
- Up to 128-way ECMP, MLAG, VXLAN bridging and routing, and VRF
