Engineered specifically for read-centric applications, the HPE P64858-001 delivers exceptional performance characteristics optimized for environments where read operations typically constitute 70-80% of storage activity. The drive maintains sustained read performance through advanced controller algorithms and NAND management techniques, ensuring consistent response times even during extended operational periods.

Speed and Latency Metrics

The drive achieves sequential read speeds up to 3,500 MB/s and sequential write speeds up to 1,200 MB/s. Random performance reaches 450,000 IOPS for read operations and 50,000 IOPS for write operations at queue depth 256. These performance metrics position the drive optimally for server applications requiring rapid data access, including database operations, web serving, and virtual desktop infrastructure.

Quality of Service (QoS)

HPE has implemented advanced QoS features that ensure predictable latency profiles, with typical read latency under 100 microseconds. This consistent performance delivery is critical for enterprise environments where storage response time directly impacts application performance and user experience.

Enterprise Features and Reliability

Data Integrity and Protection

End-to-End Data Path Protection

The P64858-001 implements comprehensive end-to-end data protection, safeguarding information from the host interface through the DRAM buffer to the NAND flash media. This protection architecture includes advanced error correction codes (ECC), power-loss protection circuits, and redundant data paths to prevent corruption and ensure data integrity throughout the storage subsystem.

Power Loss Protection (PLP)

Enterprise-grade power loss protection circuitry ensures that in-flight data is safely written to the non-volatile media during unexpected power interruptions. The drive maintains sufficient stored energy in specialized capacitors to complete all pending write operations, preventing data loss and maintaining filesystem consistency across unexpected power events.

NVMe Management Interface

Full compliance with the NVMe Management Interface specification enables robust out-of-band management through the SMBus system interface. This allows comprehensive monitoring and administration of the drive independent of the primary data path, facilitating maintenance, health monitoring, and firmware updates without impacting host system operation.

HPE InfoSight Integration

As part of HPE's comprehensive infrastructure management strategy, this drive integrates with HPE InfoSight for predictive analytics and proactive problem resolution. The system collects drive telemetry, analyzes patterns, and can predict potential issues before they impact operations, significantly enhancing overall system reliability and reducing administrative overhead.

Use Cases and Application Scenarios

General Purpose Server Storage

The P64858-001 serves as an excellent boot drive and primary storage solution for enterprise servers, providing rapid system responsiveness and fast application loading. Its read-optimized characteristics align well with operating system and application binaries that experience predominantly read-intensive access patterns after initial installation.

In virtualized environments using VMware vSphere, Microsoft Hyper-V, or KVM, this drive delivers strong performance for hosting virtual machine images, particularly in scenarios where multiple VMs are read-intensive in nature. The high random read performance enables rapid deployment and simultaneous operation of numerous virtual machines.

Database Applications

For database systems where frequently accessed reference data, indexes, and lookup tables benefit from high-speed storage, the P64858-001 provides significant performance advantages. While write-intensive database operations might require a mixed-use or write-intensive drive, read-heavy database workloads such as reporting, analytics, and query operations achieve substantial performance benefits.

Performance Tier in Storage Systems

Within software-defined storage solutions and hyperconverged infrastructure, the P64858-001 functions effectively as a performance tier for active datasets. Its balance of capacity, performance, and cost makes it suitable for caching frequently accessed data or hosting performance-sensitive applications while leveraging higher-capacity, lower-performance storage for archival data.

The drive is qualified and tested for use across HPE's server portfolio, including ProLiant DL, ML, and BL series servers as well as Apollo high-performance computing and storage systems. This comprehensive validation ensures optimal performance, management integration, and reliability when deployed within HPE server infrastructure.

U.3 Interface Compatibility

Backward and Forward Compatibility

The U.3 interface provides a unique compatibility advantage, supporting SAS, SATA, and NVMe protocols through a single connector. This enables deployment in existing U.2 infrastructure while providing a migration path to NVMe performance. The interface maintains physical compatibility with U.2 backplanes and connectors while implementing the logical signaling for NVMe operation.

NAND Flash Implementation

3D NAND Architecture

The P64858-001 utilizes current-generation 3D NAND technology, which stacks memory cells vertically to achieve higher densities and improved performance characteristics compared to planar NAND.
