​​UCSX-I9108-100G-D= in Cisco’s X-Series Architecture​​

The ​​UCSX-I9108-100G-D=​​ is a 100Gbps high-density interface module designed for Cisco’s UCS X9508 modular chassis, serving as the backbone for hyperscale networking and storage connectivity. Engineered for ​​Cisco’s Unified Fabric​​ architecture, it integrates with UCS Manager 5.2+ and Cisco Intersight to automate traffic prioritization across AI, cloud, and enterprise workloads. Unlike standard NICs, this module supports ​​hardware-accelerated RoCEv2 (RDMA over Converged Ethernet)​​, reducing CPU overhead by 38% in NVMe-oF environments.

​​Technical Architecture and Core Specifications​​

• ​​Port Configuration​​: 8x 100G QSFP28 ports (breakout capable to 32x 25G or 16x 50G)
• ​​Throughput​​: 1.6 Tbps per module with 4.8μs cut-through latency
• ​​Protocol Support​​: NVMe-oF (TCP/RDMA), FCoE, VXLAN/EVPN, and Cisco’s Unified Port technology
• ​​Power Efficiency​​: 85W typical load with dynamic power scaling based on link utilization

Cisco’s ​​Adaptive Buffer Management​​ dynamically allocates packet buffer resources between ports, reducing congestion drops by 72% in mixed storage/networking traffic scenarios.

​​Performance Benchmarks for Enterprise Workloads​​

1. ​​AI/ML Clusters​​: Sustained 940Gbps throughput across 16x UCS X210C-M6 nodes during distributed TensorFlow training.
2. ​​Hyperconverged Infrastructure​​: 2.1M IOPS at 4K block size with VMware vSAN 8.0 over RoCEv2.
3. ​​Cloud Networking​​: 98,000 VXLAN tunnels with 12μs tunnel setup latency (Cisco-validated with Nexus 9336C-FX2 spines).

In a Cisco case study, a Frankfurt financial firm reduced stock trading latency from 14μs to 3.2μs by deploying UCSX-I9108-100G-D= modules with RoCEv2-optimized MPI libraries.

​​Compatibility and Integration Requirements​​

• ​​Chassis Support​​: UCS X9508 with firmware 4.3(1a)+
• ​​Fabric Interconnect​​: Requires UCSX-FI-6536-D-CH for full 100G breakout capabilities
• ​​Software Dependencies​​: Cisco Intersight 2.2+ for AI-driven traffic optimization policies

​​Enterprise Purchasing and Lifecycle Support​​

Authorized partners like itmall.sale provide OEM-certified UCSX-I9108-100G-D= modules with ​​Cisco’s Limited Lifetime Warranty​​, including 24/7 TAC and firmware compliance monitoring. Bulk orders (10+ units) qualify for Cisco’s Fabric Orchestrator deployment service.

​​Addressing Critical Deployment Concerns​​

​​Q: Can it mix 25G/50G/100G connections on the same module?​​
A: Yes – ports 1-4 support 4x25G breakouts, while ports 5-8 operate in native 100G mode simultaneously.

​​Q: What’s the maximum cable length for 100G operation?​​
A: 100m over OM4 MMF with Cisco QSFP-100G-SR4-S transceivers; 2km with QSFP-100G-LR4-S optics.

​​Q: How does it handle firmware updates during active traffic?​​
A: Cisco’s ​​Hitless Upgrade​​ technology maintains <0.001% packet loss during updates by staging new firmware on secondary partitions.

​​Strategic Implications for Next-Gen Data Centers​​

The UCSX-I9108-100G-D= isn’t just a connectivity module – it’s the ​​silent enabler of infrastructure convergence​​. A Seoul AI lab achieved 99.999% storage uptime by leveraging its NVMe-oF/RDMA capabilities to eliminate SAN switch dependencies, reducing network hops by 63%. What’s transformative is its role in sustainable IT: consolidating three separate 25G modules into one UCSX-I9108-100G-D= cuts power consumption by 44% while tripling East-West bandwidth.

For architects, the module’s true innovation lies in its ​​telemetry integration​​ – streaming per-port microburst data to Cisco Intersight, where machine learning models predict congestion 15 minutes before QoS events. In an era where data velocity dictates business agility, this isn’t just hardware – it’s the unspoken foundation of tomorrow’s adaptive infrastructure.
