Arista DCS-7020R4M-48TX-4QC-R | 7020R4 48-Port 10G Switch, 4x 100G QSFP, TunnelSec

Q: What encryption technologies does the DCS-7020R4M-48TX-4QC-R support?
A: The 7020R4M series supports TunnelSec technology with line-rate AES-256-GCM encryption, including MACsec for layer 2 point-to-point encryption, IPsec for layer 3 encrypted tunnels, and VXLANsec for overlay network encryption. This enables secure WAN and DCI deployments without additional encryption appliances.

Q: What is the difference between the -R and -F models?
A: The -R suffix indicates rear-to-front airflow for cold aisle deployments, while the -F suffix denotes front-to-rear airflow for hot aisle configurations. Both models are functionally identical otherwise and use matched power supplies and fan modules with corresponding airflow directions.

Q: Can this switch be used for high-performance computing or storage networks?
A: Yes, the 7020R4M-48TX-4QC-R is well-suited for HPC, storage networks, and data center leaf deployments. With 880 Gbps throughput, 2GB packet buffer, ultra-low latency, and 48 ports of 10GbE connectivity plus 100G uplinks, it handles demanding applications including virtualization, VXLAN routing, and high-bandwidth data transfer.

Q: Is this switch compatible with third-party optics and cables?
A: Arista switches generally support third-party optics and DAC cables, though Arista-branded transceivers are recommended for full support and warranty coverage. The 100GbE QSFP ports accept standard QSFP28 and QSFP+ modules including SR4, LR4, and DAC options.

Q: What licensing is required for the 7020R4M series?
A: Arista 7020R4M switches run Arista EOS with base features included. Advanced functionality such as CloudVision integration and extended support may require separate licensing. Contact your Arista partner for specific licensing requirements based on your deployment needs.
