Enterprise grade solid state drive PM1643a 920GB U.2 NVMe PCIe high-speed read and write compatible with Lenovo SR650 SR630

HPE P26410-001 (PM1643a) 920GB NVMe SSD Enterprise Solid State Drive Product Introduction

Product Overview

        HPE P26410-001 (drive model PM1643a) is a classic and widely validated enterprise grade NVMe solid-state drive. It belongs to the read intensive model in HPE NVMe product line, representing HPE's mature and stable storage solution in the PCIe 3.0 era. This hard drive is designed specifically for HPE ProLiant Gen9 and Gen10 server platforms, aiming to provide a critical upgrade path from SAS/SATA to high-performance NVMe storage for these platforms. Its core values lie in excellent reliability, market proven stability, and deep firmware integration with HPE servers, making it an ideal choice for stable operation of critical business systems in enterprises.

1. Core features and specifications

         Capacity: 920 Gigabytes (GB)

         This is a classic 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 1.2 over PCIe 3.0 x4 Lanes

         During its release period, it provided revolutionary low latency and high bandwidth SSDs 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 2800 MB/s

         Continuous write speed: up to 1200 MB/s

         Random read IOPS (4K): up to 340000

          Random write IOPS (4K): up to 55000

          Note: Based on today's PCIe 4.0/5.0 standards, performance is no longer outstanding, but its performance consistency, latency stability, and quality are among the best in early NVMe drives. 

           Durability and reliability:

           DWPD (Daily Whole Disk Write Count): 1.0 (within 5-year warranty period). This means that during the 5-year warranty period, 920GB * 1.0=920GB of data can be written daily. Its durability is superior to many models with the same capacity and read density.

         TBW (maximum number of bytes that can be written): 1.68 Petabytes (PB)

         Mean Time Between Failures (MTBF): 2500000 hours

          NAND Flash Memory Type: eMLC NAND (Enterprise Multi Layer Cell)

          Adopting eMLC flash memory, This flash memory has higher durability and performance consistency than consumer grade MLC, ensuring long-term stable operation in enterprise environments.

2. Advanced features

          Enterprise Power Protection (PLP): Integrated with advanced power-off protection function, ensuring that data in cache will not be lost in case of unexpected power failure, absolutely guaranteeing 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, making it a reliable enterprise level boot drive choice 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. Compatibility

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

           For example, HPE ProLiant DL360 Gen9/10, DL380 Gen9/10 and other models can be supported after configuring the corresponding NVMe backplane upgrade kit.
