Technical Specifications & Hardware Architecture
The Cisco UCS-SD240GBMS4-EV represents Cisco’s cost-optimized storage solution for read-centric applications in UCS C220/C240 M4 server environments. Engineered with 2.5-inch SATA 6Gbps interface, this SSD balances performance and endurance through three key design principles:
- Enterprise Value Endurance: Supports 1 Full Drive Write Per Day (1 FDWP) with 3D TLC NAND technology, optimized for boot drives and streaming media workloads.
- Industrial Thermal Resilience: Operates at 0°C to 70°C ambient temperatures with 3.5W max power consumption, achieving 98.6% uptime in 72-hour burn-in tests.
- RAID-Ready Compatibility: Validated for RAID 0/1/10 configurations in Cisco UCS Manager, supporting hot-swap deployment in C240 M4 front/rear drive bays.
Third-party validation shows 3.2x higher random read performance versus 10K RPM SAS HDDs in VDI boot scenarios.
Performance Benchmarks & Use Case Optimization
In standardized tests using Cisco UCS C240 M4 servers:
| Workload Type | UCS-SD240GBMS4-EV | 10K SAS HDD | Delta |
|---|---|---|---|
| 4K Random Read | 28,500 IOPS | 8,900 IOPS | +220% |
| Sequential 128K Read | 520 MB/s | 180 MB/s | +189% |
| Boot Time (UCS Manager) | 12.3 seconds | 34.7 seconds | -65% |
The drive’s Adaptive Read Caching 2.0 extends NAND lifespan by 42% through dynamic block allocation algorithms.
Deployment Best Practices
For optimal integration with Cisco UCS infrastructure:
-
Validate RAID Controller Compatibility:
ucs-storage # verify sata-drive raid1- Supported controllers: Cisco 12G SAS Modular RAID with 2GB cache
- Max drives per RAID group: 2 for RAID1, 6 for RAID10
-
Configure Wear-Level Monitoring:
ucs-monitor # enable ssd-wear-level threshold 80- Triggers proactive replacement alerts at 80% P/E cycle utilization
-
Implement Thermal Management:
- Maintain ≥1RU vertical spacing between drive sleds
- Monitor via UCS Manager thermal sensors (threshold: 65°C)

The Paradox of Cost-Optimized Enterprise Storage
While 7.68TB NVMe drives dominate performance discussions, the UCS-SD240GBMS4-EV demonstrates that purpose-built SATA SSDs still deliver unmatched $/IOPS efficiency in read-intensive environments. Its 98.6% uptime metric at 70°C ambient conditions reveals a critical truth: enterprise storage reliability often depends more on thermal resilience than raw throughput specs. For organizations modernizing legacy HDD-based boot/streaming infrastructures, this drive represents not just a storage upgrade – it’s a thermodynamic optimization engine converting thermal headroom into operational continuity.
