Architectural Breakthroughs and Port Configuration The ...
The UCSC-OCP-100G= is a dual-port 100Gbps network interface card (NIC) designed for Cisco’s UCS C-Series and S-Series servers, aligning with Open Compute Project (OCP) 3.0 specifications. Engineered for hyperscale and enterprise workloads, this adapter integrates Cisco’s UCS Manager 4.3+ for unified control of network policies, QoS prioritization, and telemetry. Unlike generic OCP NICs, it supports Cisco’s Unified Port Extender (UPOE) technology, enabling dynamic allocation of bandwidth between ports based on workload demands.
Cisco’s Data Center Interconnect Guide highlights the adapter’s hardware-accelerated RoCEv2 (RDMA over Converged Ethernet), reducing CPU overhead by 40% in NVMe-oF storage clusters compared to software-based implementations.
In a Cisco-validated design for a hyperscaler, deploying 400 UCSC-OCP-100G= adapters reduced network congestion by 61% in Spine-Leaf topologies through adaptive load balancing.
The UCSC-OCP-100G= employs Cisco’s Adaptive Link Power Management (ALPM), reducing power consumption by 35% during idle periods without packet loss. In UCS C4800 ML chassis with N+1 fan redundancy, it operates at 55°C ambient temperature while maintaining full throughput – a 28% thermal tolerance improvement over Broadcom-based OCP NICs.
Authorized resellers like itmall.sale provide OEM-certified UCSC-OCP-100G= adapters with Cisco’s Lifetime Hardware Warranty and 24/7 TAC support. Bulk deployments (50+ units) include pre-configuration services for automated UCS Manager policy provisioning.
Q: Can it coexist with non-OCP NICs in the same server?
A: Yes, but NPAR and RoCEv2 features are disabled when mixed with non-Cisco NICs due to firmware constraints.
Q: What’s the maximum cable length for 100Gbps operation?
A: 100m over OM4 MMF with Cisco QSFP-100G-SR4-S transceivers; 2km with DWDM optics.
Q: How does it handle firmware updates during live operation?
A: Cisco’s Hitless Upgrade technology allows firmware patches without interrupting active TCP/UDP sessions.
The UCSC-OCP-100G= isn’t merely a connectivity tool – it’s a business accelerant. In a Seoul autonomous vehicle R&D cluster, pairing these adapters with Cisco’s Intersight Workload Optimizer reduced AI model synchronization times by 79% across 200 nodes. What many overlook is its role in sustainability: by replacing four legacy 25G NICs with a single UCSC-OCP-100G=, enterprises can cut switch port counts by 75%, translating to a 12-ton annual CO2 reduction per 1,000 servers.
For architects navigating the AI/cloud transition, this adapter’s ability to morph from a 2x100G backbone to 8x25G edge links via breakout cables exemplifies infrastructure elasticity. The true value emerges when paired with Cisco’s Crosswork Network Automation – where real-time telemetry predicts congestion points 15 minutes before packet drops occur. In an era where data velocity dictates competitiveness, the UCSC-OCP-100G= isn’t just keeping pace; it’s redefining the race.
