Description

The Arista 7260X is a fixed-configuration 2RU data centre switch built for top-of-rack leaf or fixed-configuration spine roles. It suits cloud, big data, virtualised and traditional data centres that need high-density 10/25/40/50/100G connectivity with low latency, and it runs Arista EOS.

This DCS-7260CX-64# provides 64 QSFP100 ports plus 2 SFP+ ports, with wire-speed Layer 2 and Layer 3 forwarding, 12.8 Tbps throughput and a 9.52 Bpps forwarding rate. Each QSFP port can run in 100GbE, 40GbE, 4x10GbE, 4x25GbE or 2x50GbE modes, scaling to 256 x 10G/25G or 128 x 50G ports. Latency is 550 to 1500ns with a 64MB dynamic packet buffer. This is the no fans, no PSU version, so fan trays and power supplies are ordered separately. Compatible parts are the FAN-7002H fan tray (4 per switch) and 1900W AC or DC supplies in a 1+1 arrangement. It is placed in EOS Feature License Group 3, with optional licences for enhanced Layer 3, VXLAN, monitoring and automation.

The QSFP100 ports accept 100GBASE-SR4, LR4, CWDM4, PSM4 and similar optics, AOC and CR4 cables, as well as 40GBASE QSFP+ optics and 4x10G breakouts. The SFP+ ports take 1GbE and 10GBASE optics and cables.
