Arista 7050SX 96-port 10GbE SFP+ switch

The Arista DCS-7050SX-128-R is a 2 RU data-centre switch with 96 1/10GbE SFP+ ports and eight 40GbE QSFP+ uplinks. It runs Arista EOS and ships with two 750 W hot-swap AC power supplies plus four hot-swap fans, all in rear-to-front airflow orientation.

Check rack space and cabling before ordering

The unit occupies 2 RU and requires a rear-to-front airflow path. Rack mounts are not included, so you must supply compatible rails. Verify you have SFP+ and QSFP+ transceivers plus single-mode or multi-mode fibre for the 96 downlink and eight uplink ports. Two RJ-45 management ports, one RS-232 console port and one USB port provide out-of-band access.

Suits high-density 10G leaf deployments

This switch fits networks that need 96 10GbE server connections aggregated over 40GbE uplinks in a compact 2 RU form factor. Buyers who need integrated rack rails, front-to-rear cooling or a different port mix should evaluate other models. Teams without SFP+ or QSFP+ optics budgets will also need to plan for those purchases.

Questions about this item

What comes in the box with the Arista DCS-7050SX-128-R and what must be purchased separately?

The switch ships with two 750W hot-swappable AC power supplies and four hot-swappable fans, both configured for rear-to-front airflow. Rack mounts are not included. SFP+ and QSFP+ transceivers are also sold separately.

How do I decide between the 96 SFP+ ports and the 8 QSFP+ ports for my uplinks?

The 96 SFP+ ports operate at 1/10GbE for server or access connections. The 8 QSFP+ ports run at 40GbE and are intended as high-speed uplinks or interconnects. Use the QSFP+ ports when you need aggregated bandwidth beyond 10GbE per link.

What does the 10GbE per SFP+ port mean once the switch is installed in a rack?

Each of the 96 SFP+ ports can negotiate 1GbE or 10GbE with the inserted transceiver and attached device, providing up to 10Gbps of throughput per port for connected servers or storage.
