HPE P28691-001 3.84TB SAS 2.5inch SSD 

The HPE P28691-001 3.84TB SAS Solid State Drive NAND and controller technology, the drive is designed to maintain consistent performance and data integrity over extended operational periods. This reliability is critical for organizations that cannot afford unplanned outages or data loss. By leveraging solid state technology, this HPE SSD reduces power consumption and cooling requirements compared to traditional spinning disks. The result is a more energy-efficient storage layer that contributes to lower total cost of ownership over the lifecycle of the system.

The HPE P28691-001 Primera 600 SSD Series

The HPE Primera 600 series represents a tier of storage media specifically optimized for HPE's Primera and Nimble Storage dHCI (disaggregated Hyper converged Infrastructure) and all-flash array platforms. These drives are not commoditized components but are deeply integrated, quality-tested, and firmware-optimized for predictable performance within HPE's ecosystem. The series is designed to deliver a balanced profile of high IOPS (Input/Output Operations Per Second), low latency, and exceptional quality of service (QoS), ensuring that applications receive consistent performance without unexpected lag spikes. The P28691-001 model sits within this performance-optimized tier, offering a substantial capacity point that caters to dense, performance-sensitive workloads.

Form Factor and Interface

The drive utilizes the ubiquitous P28691-001 2.5-inch small form factor (SFF) with a 15mm z-height, allowing for high-density storage deployment in standard server and array bays. The interface is Serial Attached SCSI (SAS), specifically a 12Gb/s dual-port SAS interface. This dual-port capability is a critical enterprise feature, providing two independent paths to the drive for redundancy. In a configured storage array or server, if one controller path fails, the second remains active, ensuring continuous data availability—a non-negotiable requirement for mission-critical systems.

3.84TB Capacity and Performance

With a usable capacity of 3.84 Terabytes (TB), this drive offers a significant balance between density and performance. It's positioned within the "Performance" tier (aligned with the Primera 600 naming), indicating it is engineered for workloads requiring high throughput and low latency. While exact IOPS and throughput figures are system-dependent, drives in this class are typically rated for hundreds of thousands of random read IOPS with microsecond-level read latencies, dramatically accelerating data access compared to traditional hard disk drives (HDDs) or even entry-level SSDs.

FIPS 140-2 Validated Encryption

This drive incorporates a hardware-based, Federal Information Processing Standards (FIPS) 140-2 Validated encryption module. FIPS 140-2 is a U.S. government computer security standard that accredits cryptographic modules. The validation means the drive's encryption implementation—including the AES (Advanced Encryption Standard) 256-bit engine, key management, and authentication mechanisms—has been rigorously tested and certified by an independent, accredited laboratory.

How FIPS Encryption Works in the Drive

The encryption is always active (always-on encryption) at the hardware level. Every bit of data written to the NAND flash memory is encrypted in real-time using a unique, internally generated encryption key. This key is itself secured by an Authentication Key (AK) set by the user via the storage system's management software. If the drive is physically removed from the system, without the proper authentication, the data remains cryptographically scrambled and inaccessible, providing robust protection against data breaches from decommissioned or stolen drives. This process is seamless and has negligible performance impact due to dedicated cryptographic hardware.

TAA Compliance Sourcing and Supply

The drive is explicitly marked as TAA-compliant. The Trade Agreements Act (TAA) is a U.S. federal statute that governs the procurement of goods by government agencies. Compliance mandates that end products must be manufactured or "substantially transformed" in the United States or a designated TAA "compliant country." For an HPE drive, this ensures the supply chain and manufacturing processes adhere to these geographic and regulatory requirements, making it eligible for sale to U.S. federal government entities and contractors who are legally obligated to purchase TAA-compliant products.

NAND Flash Type and Wear Management

While HPE P28691-001 always publicly specify the exact NAND type (e.g., TLC, 3D NAND), drives in this class typically utilize enterprise-grade 3D TLC (Triple-Level Cell) NAND. This offers an optimal balance of cost, density, and endurance. The drive's controller employs advanced wear-leveling algorithms that dynamically distribute write operations evenly across all available memory cells, preventing any single cell from wearing out prematurely. This is complemented by abundant over-provisioning (extra NAND capacity not visible to the user), which provides spare area for the controller to manage garbage collection and maintain performance and longevity.

Firmware

HPE P28691-001 certified drives undergo extensive testing to ensure alignment with controller firmware, caching algorithms, and failover mechanisms. This results in improved stability, faster deployment, and reduced downtime compared to non-certified alternatives.

Compatibility

The P28691-001 is qualified and tested for specific HPE storage platforms, primarily the HPE Primera 600 series and HPE Nimble Storage AF-Series all-flash arrays. Using HPE Genuine drives ensures the storage system's firmware can properly manage drive health, encryption, and performance telemetry. It also guarantees compatibility with HPE's predictive analytics platform, InfoSight, which can monitor drive wear and predict failures before they occur.
