High-density 100GbE leaf switch

The Arista DCS-7260CX-64-F is a 2 RU data-centre leaf switch that provides 64 ports of 100GbE QSFP28 connectivity and two 1/10GbE SFP+ uplinks. It runs Arista EOS and ships with two 1900W hot-swappable AC power supplies and four hot-swappable fans, all configured for front-to-rear airflow.

Spine-leaf fabrics needing 100GbE density

This switch suits operators building high-radix spine-leaf fabrics where 64 lanes of 100GbE are required in a compact 2 RU form factor. The single RJ-45 management port, RS-232 console and USB port support out-of-band administration. Buyers who need rear-to-front airflow, larger buffer pools for extended lossless Ethernet, or higher-speed uplink options should evaluate other platforms.

64 QSFP28 ports in 2 RU

The decisive specification is the 64 x 100GbE QSFP28 port count delivered within 2 RU, which determines whether the port density matches the fabric design. Front-to-rear cooling and the included 1900W power supplies are fixed attributes that must align with the rack airflow plan.

Questions about this item

Does the switch ship with transceivers for the 64 QSFP28 and 2 SFP+ ports, or must they be purchased separately?

The switch includes two 1900W hot-swappable AC power supplies and four hot-swappable fans with front-to-rear airflow. Transceivers for the 64 QSFP28 and 2 SFP+ ports are not included and must be purchased separately. Rack mounts are also not included.

How should I choose between the 64 QSFP28 ports and the 2 SFP+ uplink ports for my topology?

Use the 64 QSFP28 ports for 100GbE server or leaf connections. The 2 SFP+ ports operate at 1 or 10GbE and are intended for lower-speed uplinks, management aggregation, or out-of-band links.

What does the 100GbE rating on the 64 QSFP28 ports mean for actual throughput in a live rack?

Each of the 64 QSFP28 ports delivers up to 100GbE line-rate switching. The 2 SFP+ ports provide 1/10GbE connectivity. A management RJ-45 port runs at 10/100/1000 Mbps, plus a serial console and USB port are available.
