Description

The Arista 7020R4 Series Switch Router delivers 48x10GbE RJ45 ports and 4x100GbE QSFP uplinks in a compact 1RU form factor, purpose-built for data centre leaf, service provider access, and network edge deployments. With up to 2 Tbps switching throughput, deep buffer Virtual Output Queueing (VOQ) architecture, and TunnelSecâ„¢ wire-speed encryption (MACsec, IPsec, VXLANsec), it provides non-blocking, low-latency performance even under demanding traffic conditions. The rear-to-front airflow and dual AC power supplies support hot-aisle cooling configurations and high-availability requirements.

Running Arista EOS®, the 7020R4 supports EVPN-VXLAN overlay networking, MPLS, Segment Routing, and FlexRoute™ for internet-scale routing tables exceeding 2.5 million routes — all with minimal power draw. Synchronous Ethernet and IEEE 1588 precision timing make it equally suited to HPC, Big Data, and media environments. Visit iptrading.com.au to secure your order — enterprise-grade hardware with expert support.

FAQs

Q: What makes the Arista DCS-7020R4M-48TX-4QC-R suitable for data centre leaf deployments?
A: The 7020R4 Series is engineered for leaf-spine topologies with non-blocking 2 Tbps throughput, deep buffer VOQ architecture, and EVPN-VXLAN support. Its 48x10GbE RJ45 downlinks and 4x100GbE QSFP uplinks provide the density and speed required for modern data centre fabrics.

Q: What encryption capabilities does the DCS-7020R4M-48TX-4QC-R support?
A: It features Arista TunnelSec™ wire-speed encryption at both Layer 2 and Layer 3, supporting MACsec, IPsec, and VXLANsec. This allows encrypted tunnels without sacrificing throughput — critical for service provider and multi-tenant environments requiring data-in-transit security.

Q: Does this switch support MPLS and Segment Routing?
A: Yes. The 7020R4 supports a full suite of tunnelling protocols including MPLS, Segment Routing (SR), LDP, RSVP, VPLS, mLDP, and Pseudowires, as well as IPv4/IPv6 VPNs and 6PE/6VPE — making it well suited to service provider and enterprise WAN edge deployments.

Q: Can I purchase the Arista DCS-7020R4M-48TX-4QC-R in Australia?
A: Yes. IP Trading (iptrading.com.au) is an Australian B2B IT hardware reseller offering the Arista 7020R4 Series with expert pre-sales support. Contact the team to discuss availability, lead times, and volume pricing.

Q: What operating system does this switch run?
A: The DCS-7020R4M-48TX-4QC-R runs Arista EOS® (Extensible Operating System), which provides comprehensive streaming telemetry, Inband Network Telemetry, programmable pipeline features, and a consistent CLI across all Arista platforms.

Q: Is this switch suitable for high-performance computing or Big Data environments?
A: Yes. The 7020R4's deep buffer architecture is specifically designed to handle bursty workloads common in HPC, Big Data analytics, and Media & Entertainment storage environments. The VOQ architecture minimises head-of-line blocking and ensures fair bandwidth distribution across all ports.
