What is the switching capacity and port configuration of DCS-7280SR2-48YC6-F?

It provides 3.6Tbps full-duplex switching capacity with 48x SFP28 ports at 25GbE (1/10/25G multi-rate, FC/RS FEC) and 6x QSFP28 ports at 100GbE, breakout to 24x25GbE/24x10GbE/6x40GbE. 8GB buffer and 1.67Bpps forwarding support non-blocking performance.

What advanced features does EOS software offer on this switch?

EOS3 includes VXLAN bridging/routing with VRF/MLAG, 128-way MLAG/ECMP, hitless ISSU, BGP/OSPF/IS-IS, sFlow, IEEE 1588 PTP, and CloudVision management. Stateful Fault Repair enables self-healing without downtime in leaf-spine deployments.

Is this switch suitable for data center spine deployments?

Yes, with 6x100G QSFP28 uplinks and 3.6Tbps capacity, it excels as spine for scale-out fabrics. Supports high radix MLAG, deep buffers for congestion, and low-latency VOQ scheduling for 25G server access aggregation.

What high availability features are included?

1+1 hot-swap AC PSUs, 4x N+1 hot-swap fans, redundant management ports, live patching, Smart System Upgrade, and Accelerated Software Update. Platinum-efficient PSUs with color-coding ensure dynamic cooling and uptime.

What is the buffer size and its impact on performance?

8GB shared deep packet buffer with virtual output queuing manages microbursts effectively. WFQ, ETS, and distributed scheduling prevent head-of-line blocking, ideal for incast-heavy workloads in cloud/HPC environments.

Does it support storage networking protocols?

Yes, 25G SFP28 ports with RS-FEC enable NVMe-oF and Fibre Channel over Ethernet. DCB features like PFC, ETS, and DCBX ensure lossless Ethernet for storage fabrics alongside RoCEv2 support.
