Deployment Context

Where this platform fits.

Review positioning, capability notes, and deployment guidance for this xSONiC platform.

Product Positioning

XS-DC-48X25-8X100-TOR-G2 is the xSONiC 25G top-of-rack option for data center teams standardizing server access on 25G while keeping 100G uplink capacity for leaf-to-spine fabrics.

The xSONiC SKU keeps the performance profile visible: 48 ports of 25G server access, 8 ports of 100G uplink capacity, a ToR deployment role, and a second-generation Falcon-class hardware mapping.

Core Capabilities

Provides 48x25G SFP28 downlink capacity for dense server racks.
Adds 8x100G QSFP28 uplinks for spine, aggregation, or data center fabric connectivity.
Supports Enterprise SONiC capabilities including BGP-EVPN, EVPN multihoming, VXLAN overlays, RoCEv2, PFC, ECN, and congestion-aware fabric operations.
Uses Marvell Falcon 2.0T switching silicon with route capacity suitable for larger BGP and multi-tenant virtual network environments.
Fits operational workflows that rely on ZTP, Python, Ansible, telemetry, and SPAN or ERSPAN monitoring.

Technical Notes

Switching capacity: 2.0Tbps.
Packet forwarding rate: 2,600Mpps.
IPv4 and IPv6 route capacity profile: 288K IPv4 routes and 144K IPv6 routes.
Packet buffer: 24MB.
Latency profile: approximately 1400ns.
Power and cooling: 1+1 hot-swappable power supplies and 3+1 hot-swappable fan redundancy.
Physical profile: 1RU, 44 x 440 x 515mm, front-to-rear airflow.

Typical Deployment Scenarios

Use XS-DC-48X25-8X100-TOR-G2 in racks where 25G server access is the standard and the fabric needs clean 100G uplinks into spine or aggregation layers. It is especially suitable for cloud service provider pods, enterprise private cloud racks, and latency-aware environments that need RoCE-ready Ethernet fabric features without moving directly to 100G server access.

Applications and deployment scenarios

Top-of-rack leaf switching for 25G server access racks
Cloud-scale data center leaf deployments with 100G fabric uplinks
Multi-tenant virtual networks using BGP-EVPN and VXLAN overlays
Time-sensitive environments such as broadcast, finance, telecom, and smart grid networks
