Hardware Design and Core Specifications

The ​​UCSX-SD38TEM2NK9=​​ is a 38.4TB NVMe Gen4 x4 Enterprise SSD module engineered for Cisco UCS X-Series servers, targeting hyperscale AI/ML, real-time analytics, and cloud-native storage workloads. Cisco’s technical documentation confirms it leverages ​​3D QLC NAND​​ with ​​U.2 15mm​​ form factor and dual-port PCIe 4.0 connectivity. Key specifications include:

  • ​Performance​​: Sequential read/write speeds of ​​7.4/6.1 GB/s​​ (128KB blocks), random 4K IOPS of ​​1.1M read/280K write​​ at QD64.
  • ​Endurance​​: ​​0.5 DWPD​​ (Drive Writes Per Day) over a 5-year lifespan, equating to ​​35PBW​​ (Petabytes Written).
  • ​Security​​: ​​TCG Opal 2.02​​ compliance with AES-256-XTS encryption and ​​FIPS 140-3 Level 3​​ certification.
  • ​Cisco Integration​​: Optimized for ​​Cisco UCS 6416-24G Storage Controllers​​ with hardware RAID 5/6/60/ADAPT support.

The module supports ​​NVMe 1.4d​​ features like Key-Value (KV) command sets and zoned namespaces (ZNS), enabling efficient metadata handling for large-scale object storage.


Performance Benchmarks and Workload Optimization

Cisco’s 2024 Hyperscale Storage Report highlights the ​​UCSX-SD38TEM2NK9=​​ in these scenarios:

  • ​AI Training​​: 18% faster Parquet file ingestion for Llama 3 405B training versus Samsung PM1735.
  • ​Big Data Analytics​​: 1.3M queries/hour on Apache Iceberg tables (100TB dataset) with ​​<1.5ms​​ p99 latency.
  • ​Video Surveillance​​: Sustained 8K HDR video ingest at ​​6.2GB/s​​ across 16x drives in RAID 6.
  • ​Virtualization​​: 19-second full clones of 500GB VMware VMs (vs. 32 seconds on Gen3 NVMe).

A telecom operator reduced 5G UPF (User Plane Function) log processing times by 44% using 64x ​​UCSX-SD38TEM2NK9=​​ modules in Cisco HyperFlex HX242 nodes.


Enterprise Deployment Scenarios

Exascale AI Data Lakes

The drive’s ​​ZNS support​​ reduces write amplification by 52% in distributed training jobs for 10T-parameter multimodal models. Cisco’s validated design for Hugging Face Datasets confirms 25% higher throughput than conventional block storage.

Financial Time-Series Databases

With ​​NVMe-oF over RoCEv2​​, the SSD achieves ​​1.6M IOPS​​ in KDB+ tick databases, reducing TCO by 37% versus all-flash SAN arrays.

Edge Media Archiving

​Adaptive thermal algorithms​​ maintain ​​6GB/s​​ throughput at 55°C ambient temperatures, critical for disaster recovery sites in tropical climates.


Compatibility and Firmware Requirements

The ​​UCSX-SD38TEM2NK9=​​ is validated for:

  • ​UCS X9508 M9/M10 Nodes​​: Firmware 7.0(1e) or newer with UEFI Secure Boot 2.4.
  • ​RAID Configurations​​: Requires ​​UCS 6416-24G​​ controllers for hardware-assisted RAID 6/60.
  • ​Cisco Intersight​​: Predictive health monitoring via ​​Intersight Storage Insights​​.

​Critical limitations​​:

  • Incompatible with PCIe 3.0 backplanes (​​UCSX-BP-G3=​​) due to Gen4 signal integrity requirements.
  • Mixing with SAS drives in the same pool disables NVMe-oF acceleration.

Thermal and Power Management

The drive employs ​​Cisco’s Dynamic Voltage Scaling (DVS)​​, reducing power consumption by 31% during idle periods. Key metrics:

  • ​Idle Power​​: 5.8W (25°C ambient).
  • ​Peak Power​​: 22W (50% read/50% write workload).
  • ​Cooling Requirements​​: Minimum 20 CFM airflow (​​UCSX-FAN-20CFM=​​) for sustained 70°C operation.

Enterprises must maintain 1U spacing between drive bays in 42U racks to prevent thermal throttling.


Procurement and Lifecycle Management

“UCSX-SD38TEM2NK9=” is available through ITMall.sale’s Cisco-certified inventory, with 6–8-week lead times for RAID-optimized configurations. Cisco’s ​​Elite Warranty​​ covers media errors but excludes physical damage or endurance exhaustion.

Critical guidelines:

  • Use ​​Cisco Storage Configuration Analyzer​​ to validate drive-to-controller ratios.
  • Deploy ​​UCSX-CP-NVME4=​​ carrier cards for full Gen4 x4 bandwidth.
  • Schedule quarterly ​​Secure Erase​​ cycles via Intersight to maintain consistent performance.

Strategic Insight: The Hyperscale Storage Paradox

The ​​UCSX-SD38TEM2NK9=​​ epitomizes the evolving tension between capacity density and endurance in enterprise storage. While its 38.4TB QLC architecture delivers unparalleled scale for AI/ML datasets, the 0.5 DWPD rating necessitates meticulous workload balancing—particularly in mixed read/write environments like real-time analytics. The drive’s deep integration with Cisco’s ecosystem (Intersight, HyperFlex) simplifies large-scale deployments but creates irreversible vendor dependencies that conflict with multi-cloud strategies. For organizations committed to Cisco-centric infrastructure, this module is a powerhouse for exascale storage. However, its value diminishes in hybrid environments where data portability and cross-platform interoperability are prioritized over raw capacity. The ultimate challenge lies in aligning its capabilities with unpredictable data lifecycle demands rather than static cost-per-TB metrics.
