HPE 874429-001 (PM1635a) 400GB NVMe SSD Enterprise Solid State Drive Product Introduction

Product Overview

        HPE 874429-001 (disk body model PM1635a) is a high-performance, low latency enterprise class NVMe solid state drive, belonging to the hybrid model in HPE NVMe product line. It is designed specifically for HPE ProLiant Gen9 and Gen10 server platforms, aiming to provide critical upgrades from SAS/SATA to high-performance NVMe storage for these platforms. This hard drive provides an excellent balance between read and write performance, making it suitable for enterprise level applications, virtualization environments, and database systems that require sustained high performance and exceptional reliability.

1. Core features and specifications

          Capacity: 400 Gigabytes (GB)

           This is an enterprise level capacity point that ensures long-term performance stability and durability through additional over provisioning.

          Interface and Protocol: NVMe 1.2 over PCIe 3.0 x4 Lanes

          Provide high-performance PCIe channels to ensure low latency and high-throughput data access.

          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 3200 MB/s

          Continuous write speed: up to 1700 MB/s

          Random read IOPS (4K): up to 450000

          Random write IOPS (4K): up to 75000

         Note: Performance varies depending on server configuration, drivers, and workload.

         Durability and reliability:

         DWPD (Daily Whole Disk Write Count): Typically 3.0 (within the 5-year warranty period). This means that during the 5-year warranty period, 400GB * 3.0=1.2TB of data can be written daily.

         TBW (maximum number of bytes that can be written): 2.19 Petabytes (PB)

Mean Time Between Failures (MTBF): 2000000 hours

         NAND flash type: MLC NAND

         Adopting MLC (Multi Layer Cell) flash memory, this type of flash memory has high durability and performance consistency.

 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, achieving out of the box compatibility, simplified deployment, and centralized monitoring.

3. Typical application scenarios

         This NVMe SSD is optimized for the following enterprise level applications:

Enterprise level databases: Oracle, SQL Server and other database systems

          Virtualization platforms: VMware HANA, Microsoft Hyper-V, and other virtualization environments

          High performance computing: scientific computing and engineering applications that require high-speed data access

          Cloud Infrastructure: Basic Storage Devices for Public and Private Cloud Platforms
