All productsULTRA-LOW LATENCY PACKET BUFFERING ENGINE FACTSHEET: PROCESSING LATENCY MICROSECONDS DATA CENTER
PRODUCT IDENTIFICATION & DEPLOYMENT HIGHLIGHTS
The [PLATFORM XG9] series represents a paradigm shift in data center switching fabric design, engineered specifically for environments where sub-10-microsecond processing latency is a non-negotiable operational imperative. This factsheet details the hardware architecture of a non-blocking, cut-through Ethernet switching engine capable of deterministic microsecond-grade forwarding across 64x 100GE ports.
STRUCTURAL CHASSIS OVERVIEW
The 1RU compact chassis integrates a passive copper backplane and a front-access serviceability layout. The aerospace-grade aluminum chassis dissipates thermal loads efficiently, supporting a 0-40°C operating range without performance throttling. All active components, including the dual-redundant power supply units (PSUs) and field-replaceable fan trays, are hot-swappable, ensuring 99.999% uptime for financial trading and high-performance computing (HPC) clusters.
SUPPORTED TRANSCEIVER INTERFACES
– **QSFP-DD (800G):** OSFP/QSFP-DD cages supporting 100G, 400G, and 800G optical modules (SR4, DR4, FR4, LR4).
– **SFP28 (25G):** 8x SFP28 ports for hybrid legacy aggregation supporting 10/25GE.
– **Copper Ports:** 2x RJ45 (10/100/1000BASE-T) for out-of-band management.
– **Breakout Support:** 4x 100G ports can breakout to 4x25G SFP28.
PERFORMANCE SPECIFICATIONS (PROCESSING LATENCY MICROSECONDS DATA CENTER)
– **Cut-Through Latency (64-byte frame):** 490 nanoseconds (typical).
– **Store-and-Forward Latency (1518-byte frame):** 1.2 microseconds.
– **Processing Latency (Hardware ASIC, any frame size):** ≤ 2.4 microseconds across all port densities.
– **Jitter (PKT-PKT):** ±5 ns (deterministic).

TOPOLOGY SCHEMATIC: DATA CENTER LEAF-SPINE INTEGRATION
When deployed as a leaf node in a two-tier spine-and-leaf topology, the XG9 achieves a deterministic East-West latency of 3.9 microseconds (including two optical transceivers and patch panel connections). For spine roles, the aggregated switching capacity of 12.8 Tbps eliminates any backpressure queuing delay, guaranteeing microsecond-class processing for RDMA over Converged Ethernet (RoCEv2) traffic.
