HP Enterprise K2Q45A

HP Enterprise K2Q45A – 200 GB 12 Gb/s SAS Solid‑State Drive

The HP Enterprise K2Q45A is a high‑performance, enterprise‑grade solid‑state drive (SSD) designed for use in HP’s Modular Smart Array (MSA) storage systems. It delivers reliable data access and endurance while maintaining the compact 2.5‑inch form factor required by modern data centers.

Key Features

• Capacity: 200 GB – ideal for small to medium workloads, cache, or tiered storage solutions.
• Interface: 12 Gb/s SAS (Serial Attached SCSI) – provides low latency and high throughput suitable for mission‑critical applications.
• Form Factor: 2.5‑inch Small Form Factor (SFF) – fits into standard hot‑swap bays of MSA 1040, 2040, and 2050 arrays.
• Performance: Up to 200 000 IOPS read/write with ≤ 1 ms latency, ensuring rapid data retrieval for database and virtualization workloads.
• Endurance: Rated for 2.5 TBW (Terabytes Written) – supports heavy write cycles typical in enterprise environments.
• Reliability: Enterprise‑grade firmware with built‑in error correction, wear leveling, and SMART monitoring.
• Hot‑Swap Capability: Supports seamless replacement without downtime, critical for high availability systems.

Design & Build Quality

The K2Q45A features a rugged metal enclosure that protects the NAND flash memory from physical shock and vibration. Its low power consumption (≤ 1.5 W) reduces heat output, allowing dense packing of drives in hot‑swap shelves without excessive cooling requirements.

Compatibility

This SSD is fully compatible with HP’s MSA 200GB 12G ME SAS SFF series and can be deployed in:

• HP MSA 1040 – entry‑level storage arrays for small businesses.
• HP MSA 2040 – mid‑range arrays with higher capacity and performance demands.
• HP MSA 2050 – high‑end, enterprise‑grade arrays supporting advanced features like deduplication and compression.

Use Cases

• Database Caching: Accelerate read/write operations for relational databases such as Oracle or Microsoft SQL Server.
• Virtualization: Provide fast storage for virtual machine images in VMware vSphere or Hyper‑V environments.
• Tiered Storage: Act as a high‑speed tier between slower HDDs and SSDs, improving overall system performance.
• Backup & Recovery: Store incremental backups with quick restore times due to low latency.

Installation & Management

The K2Q45A is plug‑and‑play. Once inserted into a hot‑swap bay, the MSA array automatically detects and configures the drive. HP’s Array Configuration Utility (ACU) allows administrators to monitor health metrics, firmware updates, and performance statistics in real time.

Firmware & Software Support

HP provides regular firmware releases that enhance reliability, add new features, and improve compatibility with evolving storage protocols. The drive supports SAS 6.0/7.0/8.0/9.0/10.0 standards, ensuring future‑proofing for array upgrades.

Environmental Considerations

The K2Q45A operates within a temperature range of 5 °C to 55 °C and is rated for 1 GPM (gallons per minute) airflow. Its low power profile contributes to reduced energy consumption, aligning with green data center initiatives.

Conclusion

The HP Enterprise K2Q45A delivers a balanced mix of capacity, speed, and durability in a compact 2.5‑inch package. Whether you’re building a new storage array or expanding an existing MSA system, this SSD provides the performance and reliability required by today’s demanding enterprise workloads.
