The Arista DCS-7280SR2A-48YC6 is a 1U Layer 2 and Layer 3 data center switch from the Arista 7280R2 Series. Specifically, it combines 48 SFP28 ports with 6 QSFP28 uplinks and 3.6 Tbps of switching capacity. As a result, it serves as a high-performance 25G leaf or edge router for data center and service provider networks.

48x 25G Access Ports and 6x 100G Uplinks

In addition, the 48 SFP28 ports run at 1G, 10G, or 25G, while the 6 QSFP28 ports run at 40G or 100G. Consequently, operators can connect servers and storage at 25G and uplink to a spine or core at 100G. Moreover, the switch forwards up to 1.67 billion packets per second.

Deep Buffers for Congested Networks

Unlike shallow-buffer leaf switches, the 7280R2 Series includes 8GB of deep packet buffer. Therefore, it absorbs traffic bursts and congestion without dropping packets, which helps storage, big data, and mixed east-west and north-south traffic. Likewise, its 768,000-entry MAC table supports large-scale deployments.

AlgoMatch Programmable Packet Classification

The “A” in SR2A stands for AlgoMatch, Arista’s programmable packet classification engine. In other words, it expands ACL scale and enables advanced policy-based forwarding and custom telemetry. For this reason, the SR2A suits networks that need richer security and traffic policies than standard merchant-silicon switches offer.

Arista EOS, Redundancy, and Airflow Options

Also, the switch runs Arista EOS with VXLAN, EVPN, MLAG, and streaming telemetry, and operators can manage it through CloudVision. Furthermore, it uses redundant, hot-swappable power supplies (1+1) and fans (N+1). Finally, Arista offers two airflow versions: DCS-7280SR2A-48YC6-F (front-to-rear) and DCS-7280SR2A-48YC6-R (rear-to-front).

Key Features

• First, it provides 48x 1/10/25G SFP28 ports.
• Second, it adds 6x 40/100G QSFP28 uplinks.
• Additionally, it delivers 3.6 Tbps and up to 1.67 Bpps.
• Furthermore, 8GB of deep buffer absorbs traffic bursts.
• Moreover, AlgoMatch expands ACL scale and policy control.
• Finally, redundant power and fans keep it running through a single failure.

Why Lease from Telecom Leasing?

• First, you upgrade to 25G/100G without a large capital outlay.
• Second, we test every unit so it’s ready to deploy.
• In addition, flexible terms cover spares, upgrades, and project builds.
• Finally, you get fast quotes and quick shipping.

Best of all, Telecom Leasing offers the DCS-7280SR2A-48YC6 for lease or purchase, so you can add deep-buffer switching at a fraction of new cost.
