What is the switching capacity and port configuration of DCS-7050SX2-72Q-F?

It delivers 1.44Tbps full-duplex switching capacity with 48x10GbE SFP+ downlink ports and 6x40GbE QSFP+ uplinks. This supports 960Mpps forwarding with non-blocking wire-speed performance across all ports, ideal for spine aggregation in 10/40G data center fabrics.

What latency does the Arista DCS-7050SX2-72Q-F achieve?

Ultra-low latency of 550ns is achieved for L2/L3 forwarding on 10GbE ports, with QSFP+ ports at similar sub-microsecond levels. This enables high-frequency trading, RDMA over Converged Ethernet, and low-jitter VoIP/video in enterprise deployments.

Does it support VXLAN and overlay networking?

Yes, native VXLAN routing with VM Tracer supports cloud-scale overlays. Combined with 288K MAC entries and 16MB buffers, it handles thousands of virtual machines with efficient underlay/overlay separation and multicast optimization.

What management features are available?

CloudVision portal, ZTP, eAPI, OpenFlow, sFlow, and Linux-based tools including TCPDump. Dual 1GbE mgmt ports, SSHv2, SNMPv3, and optional 50GB SSD enable automated provisioning and deep troubleshooting in large-scale environments.

What power and cooling options does it have?

Dual 1+1 redundant hot-swap AC PSUs (460W each) with front-to-rear airflow. N+1 hot-swap fans maintain operation under full load; typical draw under 2W/port supports efficient dense rack deployments up to 40°C ambient.

Is it suitable for RoCE storage fabrics?

Yes, 16MB dynamic buffers and PFC support lossless RoCEv2. 32-way ECMP and low latency optimize NVMe-oF fabrics, preventing head-of-line blocking in bursty AI/ML training and distributed storage workloads.
