Cisco UCS-SD19T63X-EP Enterprise Performance SATA SSD

Understanding the UCS-SD19T63X-EP Solid State Drive

The Cisco UCS-SD19T63X-EP represents the pinnacle of enterprise storage technology, specifically engineered for demanding data center environments. This 1.9TB SATA 6Gbps solid-state drive combines exceptional performance, reliability, and integration capabilities within the Cisco Unified Computing System (UCS) ecosystem. Designed for the 2.5-inch small form factor (SFF) with included hot-swap tray, this enterprise performance drive delivers the consistent I/O required for today's most critical workloads.

Enterprise-Grade Storage Architecture

Built with enterprise-class NAND flash memory and advanced controller technology, the UCS-SD19T63X-EP ensures consistent performance under sustained workloads. Unlike consumer-grade SSDs that may throttle under continuous operation, this drive maintains predictable latency and throughput characteristics essential for database applications, virtualization platforms, and high-transaction environments.

Endurance and Write Performance

With optimized wear-leveling algorithms and over-provisioning, the UCS-SD19T63X-EP delivers exceptional write endurance, significantly exceeding consumer SSD capabilities. The drive's architecture ensures balanced performance across read and write operations, making it suitable for mixed-workload environments where both data retrieval and storage operations occur simultaneously.

Technical Specifications and Performance Characteristics

Capacity and Interface Technology

The 1.9TB capacity point represents an optimal balance between storage density and performance characteristics. Utilizing the SATA 6Gbps interface, this drive provides compatibility with existing infrastructure while delivering maximum interface bandwidth. The SATA interface ensures broad compatibility across Cisco UCS servers and storage systems, providing a seamless upgrade path from traditional hard disk drives.

Form Factor and Physical Design

Housed in a 2.5-inch small form factor (SFF) design, the UCS-SD19T63X-EP maximizes storage density in constrained rack environments. The included hot-swap tray facilitates easy installation and maintenance without requiring system downtime. The drive's mechanical design incorporates vibration resistance and thermal management features crucial for high-density server configurations.

Performance Metrics and Benchmarking

Enterprise Performance classification indicates consistent I/O operations per second (IOPS) across random read and write patterns. The UCS-SD19T63X-EP delivers low latency access times measured in microseconds rather than milliseconds, dramatically improving application responsiveness compared to traditional spinning media. Sequential read and write performance approaches the theoretical maximum of the SATA 6Gbps interface.

Sustained Performance Under Load

Unlike entry-level SSDs that may experience performance degradation during extended write operations, the UCS-SD19T63X-EP maintains consistent throughput through advanced garbage collection and background maintenance algorithms. This consistent performance profile ensures predictable application behavior during peak workload periods.

Integration with Cisco Unified Computing System

UCS Manager and Integrated Management

The UCS-SD19T63X-EP seamlessly integrates with Cisco UCS Manager, providing centralized management and monitoring capabilities.

For many enterprise workloads, SATA SSDs deliver sufficient performance with broader infrastructure compatibility and lower acquisition costs.

SSD vs. Traditional Hard Disk Drives

The performance differential between the UCS-SD19T63X-EP and traditional hard disk drives is measured in orders of magnitude for random I/O operations. SSD technology eliminates mechanical latency entirely, reducing access times from milliseconds to microseconds. This performance transformation enables entirely new application architectures and performance profiles.

NVMe Technology Considerations

While NVMe drives offer higher theoretical performance through PCIe interfaces, the UCS-SD19T63X-EP SATA SSD remains relevant for applications that don't require extreme performance or where existing infrastructure investments prioritize SATA compatibility. The SATA interface also typically offers better capacity economics for high-density storage configurations.
