Arista DCS-7020SRG-24C2-F | 7020R 24-Port 10G Switch with IPSec, 2x 100G QSFP+

Q: What is the difference between the 7020SR and 7020SRG models?
A: The 7020SRG models include dedicated hardware IPSec encryption support capable of up to 20Gbps throughput for secure site-to-site VPN tunnels using AES-256 and SHA-256. The standard 7020SR models do not include this IPSec acceleration capability. IPSec requires a separate EOS license to enable.

Q: Can the SFP+ ports operate at both 1G and 10G speeds?
A: Yes, all 24 SFP+ ports support both 1GbE and 10GbE operation with no restrictions, providing maximum flexibility for mixed-speed environments. The 100G QSFP ports can also be broken out into 10G, 25G, or 40G configurations.

Q: What deployment scenarios is this switch best suited for?
A: The DCS-7020SRG-24C2-F excels in data center leaf roles, hyper-converged infrastructure, storage networks, and edge routing with secure data center interconnect via IPSec VPN. The deep 3GB buffer with VOQ architecture makes it ideal for environments with traffic bursts, speed mismatches, or lossless forwarding requirements.

Q: Does this model support stacking or clustering?
A: The 7020R Series supports MLAG (Multi-Chassis Link Aggregation) for redundancy and load balancing across switch pairs, as well as ECMP for multi-path routing. It does not use traditional stacking but leverages these proven data center technologies for high availability.

Q: What airflow direction does the -F suffix indicate?
A: The -F suffix designates front-to-rear airflow (port side intake, rear exhaust), suitable for cold aisle/hot aisle data center deployments where equipment intakes cool air from the front and exhausts hot air to the rear.
