OSFP vs QSFP-DD: The PX5 Platform

• OSFP Connector Advantages: Improved thermal management for high-power optics, support for pluggable optics modules that can be field-upgraded without hardware replacement, and direct interoperability with OSFP-based ecosystem partners
• Linear Pluggable Optics (LPO) Support: OSFP supports LPO technology, enabling customers to deploy optics that conform to the Linear Pluggable Transceiver (LPT) specification — a next-generation approach to optics modularity that further reduces total cost of ownership and enables mixed optics deployments across a fabric without dedicated breakout modules
• Identical Performance and Feature Set: The PX5-64E delivers the same 25.6 Tbps throughput, 114 MB buffer, 825 ns latency, and full EOS feature set as the DX5-64E — the only difference is the OSFP interface rather than QSFP-DD
• Software Difference: Minimum EOS version is 4.29.1 (vs 4.31.0 for the DX5-64E), reflecting the platform’s earlier stabilization date

25.6 Tbps Non-Blocking Architecture

825 ns Cut-Through Latency

114 MB Deep Shared Buffer: Built for 800G AI, Storage, and Synchronized Traffic

• 800G AI/ML training fabrics: Distributed training jobs at 800G scale with collective operations (AllReduce, AllGather) generate synchronized, simultaneous bursts from hundreds or thousands of GPUs toward the same destination. The 114 MB buffer absorbs these all-reduce events at the spine layer, maintaining GPU utilization and keeping training time predictable.
• High-speed NVMe-oF and storage fabrics: Storage reads and writes at 800G generate large, bursty transfers that arrive in waves. The PX5-64E’s deep shared buffer prevents head-of-line blocking and packet drops that force storage retransmissions and inflate I/O latency.
• East-west incast in 800G leaf-spine fabrics: When multiple leaf switches simultaneously send traffic to the same destination through a spine at 800G rates, the spine port toward that destination absorbs an incast burst many times the individual leaf rate. The 114 MB shared pool provides buffer headroom to absorb these events without drops.

Advanced Load Balancing and Traffic Engineering

• Dynamic Load Balancing (DLB): Real-time flow rebalancing for AI/ML all-reduce and storage traffic patterns
• Cluster Load Balancing (CLB): Advanced hashing and traffic steering for GPU cluster traffic
• AI Analyzer: Hardware-based monitoring of ECMP utilization at 100 microsecond granularity

Spine-Optimized Fabric Support: VXLAN, EVPN, and 128-Way ECMP

• EVPN: BGP-based control plane for distributed MAC/IP learning, multi-tenancy, and seamless MAC mobility across the fabric
• Up to 128-way ECMP: Maximum path diversity across the spine layer, distributing east-west load evenly across all leaf uplinks
• BGP and IS-IS: Full-featured underlay routing for IP fabric, routed-spine, and eBGP-based CLOS topologies
• MLAG (Multi-Chassis Link Aggregation): Up to 64-way MLAG for redundant dual-homed leaf switch connectivity

RoCEv2 and Lossless Ethernet

• RoCEv2 (RDMA over Converged Ethernet): GPU-Direct RDMA support with Per-Priority Flow Control (PFC) for zero-loss fabric operation

Deployment Scenarios and Industry Applications

• 800G AI/ML Training Fabrics with OSFP Optics: Organizations standardizing on OSFP for their 800G optics ecosystem — the PX5-64E provides native 800G OSFP connectivity with 114 MB buffer, DLB/CLB load balancing, and LANZ telemetry optimized for GPU cluster all-reduce traffic at 800G scale. Ideal for AI research facilities and hyperscale operators leveraging OSFP-based infrastructure investments.
• Linear Pluggable Optics (LPO) Deployments: Organizations evaluating or standardizing on LPO technology for field-upgradeable transceiver configurations — the OSFP connector enables direct LPO module compatibility without separate conversion or breakout adapters, reducing total cost of ownership across the fabric lifecycle.
