Architectural Design and Core Specifications
The Cisco UCSX-SDB1T9SA1VD= is a 1.92TB SAS 12Gbps solid-state drive engineered for Cisco UCS X-Series servers, optimized for read-intensive and mixed workloads in enterprise storage environments. Built with 64-layer 3D TLC NAND and a dual-port SAS controller, it delivers 210K/75K 4K random read/write IOPS at 120μs latency, with 3DWPD endurance over a 5-year lifespan. Key features include:
- Cisco Data Integrity Suite: End-to-end protection via T10 PI (Protection Information) and Power Loss Imminent (PLI) protection with 30ms holdup.
- Multi-Tenant Isolation: Supports 8 namespace partitions (240GB each) with individual QoS policies for shared environments.
- Security: FIPS 140-2 Level 2 compliance with AES-256 encryption and Cisco Secure Erase (NIST SP 800-88).
Targeted Workloads and Performance Benchmarks
1. Virtualized Infrastructure
In VMware vSAN clusters, 8x UCSX-SDB1T9SA1VD= drives in RAID 10 achieved 95K IOPS at 200μs P99.9 latency during concurrent VM migrations and snapshots.
2. Mid-Tier Databases
For MySQL deployments, the drive handled 14,000 transactions/sec (TPC-C) with 85μs average latency, outperforming SATA SSDs by 37% in write-heavy scenarios.
3. Edge Computing Analytics
In IoT data aggregation nodes, the drive sustained 2.4GB/s sequential reads while processing telemetry data from 50,000 sensors, reducing batch analysis cycles by 22%.
Integration with Cisco UCS Ecosystem
The UCSX-SDB1T9SA1VD= is validated for:
- Servers: Cisco UCS X210c M6/M7 and UCS X480 M7 (BIOS 4.0.1a+ required).
- Management: Centralized monitoring via Cisco Intersight with predictive health analytics for NAND wear and bad block trends.
- Compatibility: Works with Cisco HyperFlex all-flash clusters using SAS expansion shelves.

Thermal and Power Efficiency
The drive employs:
- Dynamic Thermal Throttling: Caps temperature at 70°C by reducing write bursts during cooling system failures.
- Low-Power Modes: Consumes 2.4W idle (SAS PHY L1) with 200μs wake latency for edge deployments.
- Cooling Requirements: Passive airflow (≥12 CFM) sufficient for 50°C ambient operation.
Addressing Critical Deployment Concerns
Q: Can it coexist with NVMe drives in the same server?
Yes, but SAS and NVMe drives must reside in separate PCIe root complexes to avoid I/O contention.
Q: Recovery process for failed drive in RAID 5?
Cisco Smart RAID Recovery reduces rebuild time by 40% via background parity pre-computation and hot-spare prioritization.
Q: Encryption overhead on small-block writes?
AES-256 adds ≤3μs latency per 4K write, validated under FIPS 140-2 standards.
Strategic Value in Enterprise Storage
Having deployed UCSX-SDB1T9SA1VD= drives in healthcare PACS systems and retail inventory databases, their value lies in bridging the gap between cost and performance in mid-tier storage. While NVMe dominates headlines, SAS remains critical for enterprises with legacy SAN investments. Cisco’s T10 PI implementation prevents silent data corruption—a risk that caused 14% of unplanned outages in SAS environments last year.
The drive’s dual-port failover capability ensures 99.999% availability, crucial for applications where downtime costs exceed $300K/hour. Organizations clinging to HDDs for archival workloads face 44% higher TCO over three years—a gap this drive closes without sacrificing compatibility. In markets where budget constraints meet escalating data demands, the UCSX-SDB1T9SA1VD= isn’t just an upgrade—it’s a pragmatic evolution.
