Product Positioning
XS-DC-32X400-SP-G2 is the xSONiC 400G spine/core platform for data center teams
building higher-capacity leaf/spine fabrics, AI-ready backbones, and EVPN-based
aggregation layers. It uses a performance-first xSONiC SKU: 32 ports of 400G, spine/core
role, and a G2 Falcon-class variant.
Core Capabilities
- Delivers 32x400G QSFP-DD ports for spine, super-leaf, or compact core roles.
- Provides 12.8Tbps switching capacity for 400G fabric growth.
- Supports VXLAN, BGP-EVPN, EVPN multihoming, MC-LAG, ECMP, and DCI patterns.
- Supports RoCEv2-oriented Ethernet fabric designs and automation-led
operational workflows.
- Includes optional PTP timing support for financial, broadcast, telecom, smart
grid, AI/ML, and other time-sensitive environments.
Technical Notes
- Switching capacity: 12.8Tbps.
- Packet forwarding rate: 5,600Mpps.
- IPv4 and IPv6 route capacity profile: 288K IPv4 routes and 144K IPv6 routes.
- MAC address entries: 128K.
- Packet buffer: 48MB.
- Latency profile: approximately 1500ns.
- Power and cooling: 1+1 hot-swappable power supplies and 5+1 hot-swappable fan
redundancy.
- Physical profile: 1RU, 44 x 440 x 515mm.
Typical Deployment Scenarios
Use XS-DC-32X400-SP-G2 when 100G fabrics need a compact 400G spine layer, or
when AI, HPC, cloud, and data center interconnect environments need higher
backbone capacity without moving directly to 800G. It is positioned as the
400G step between 100G leaf/spine fabrics and the highest-end 800G AI fabric
class.
