HPE P02434-001 (PM1643) 920GB NVMe SSD Enterprise Solid State Drive Product Introduction

Product Overview

HPE P02434-001 (disk body model PM1643) is an earlier generation but classic and reliable enterprise NVMe solid-state drive.It was born in the early stages of NVMe technology's popularity in the enterprise market, providing a critical upgrade path from SAS/SATA to high-performance NVMe storage for HPE ProLiant Gen9 and Gen10 servers.This hard drive is positioned for read intensive workloads, designed to provide significant performance improvements for operating systems, applications, and cache, and is known for its proven stability and deep integration with the HPE platform.

1.Core features and specifications

Capacity: 920 Gigabytes (GB)

This is a typical enterprise level capacity point.The available capacity for its users is less than 1TB due to the large amount of Over Previewing (OP) space set in the hard drive firmware for garbage collection, wear leveling, and maintaining long-term stable high performance.

Interface and Protocol: NVMe 1.1 over PCIe 3.0 x4 Lanes

Provided revolutionary low latency and high bandwidth SSDs during its release period, with performance far exceeding that of SATA and SAS interfaces of the same period.

Form Factor: 2.5 inches U.2 (SFF-8639)

Adopting a standard 2.5-inch hard drive appearance, it can be installed into the server's standard 2.5-inch hot swappable disk slots (requiring the server backplane to support NVMe protocol).

Performance indicators (typical values):

Continuous reading speed: up to 2700 MB/s

Continuous write speed: up to 1100 MB/s

Random read IOPS (4K): up to 300000

Random write IOPS (4K): up to 40000

Note: Based on today's PCIe 4.0/5.0 standards, the performance is no longer outstanding, but it was a representative of high-end performance when it was released.

Durability and reliability:

DWPD (Daily Whole Disk Write Count): Typically 0.7 (within the 5-year warranty period).This means that during the 5-year warranty period, 920GB * 0.7=~644GB of data can be written daily.This clearly defines its applicability to applications with small write volumes.

TBW (maximum number of bytes that can be written): 1.17 Petabytes (PB)

Mean Time Between Failures (MTBF): 2000000 hours

NAND flash memory type: MLC or eMLC NAND

As an earlier model, it is likely to have adopted MLC (Multi Layer Cell) or eMLC (Enterprise MLC) flash memory, which has higher durability and reliability than modern TLC flash memory 2.Advanced features

Enterprise Power Protection (PLP): Integrated power-off protection function ensures that data in cache will not be lost in case of unexpected power failure, ensuring data integrity.

End to end data protection: Implement protection mechanisms throughout the entire data path to prevent silent errors during data transmission.

HPE exclusive firmware and integration: Pre flashed HPE intelligent firmware, deeply integrated with the iLO management engine of HPE ProLiant servers (such as Gen9, Gen10), achieving out of the box compatibility, simplified deployment, and centralized monitoring. This is one of the main advantages of choosing HPE original parts.

3.Typical application scenarios

This NVMe SSD is optimized for the following applications on the HPE platform:

Server operating system boot drive: Provides extremely fast system startup and application loading speed, and is one of the best boot disk choices for Gen9/Gen10 servers.

Universal Enterprise Storage: Provides high-speed storage support for file servers, mail servers, web servers, and more.

Read intensive cache: As a read cache layer for databases or virtualization environments, it accelerates frequently accessed data.

Application Acceleration: Hosting applications that require quick response and improving user experience.

4.Compatibilit

Server Platform: Mainly aimed at HPE Gen9 and early Gen10 servers that require NVMe enabled backplanes.

For example, HPE ProLiant DL360 Gen9, DL380 Gen9, DL160 Gen10 and other models can be supported after configuring the corresponding NVMe backplane upgrade kit.
