HPE 816876-002 (PM863) 240GB NVMe SSD Enterprise Solid State Drive Product Introduction

Product Overview

    HPE 816876-002 (disk body model PM863, derived from Samsung) is an early, ultra-high performance enterprise class NVMe solid-state drive. It is a flagship model in HPE's first NVMe product line, designed specifically for the HPE ProLiant Gen9 server platform, aiming to provide the ultimate low latency and ultra-high IOPS performance for the most demanding critical business applications. This hard drive represented the pinnacle of NVMe technology at the time, primarily targeting scenarios that required extreme performance such as database acceleration, high-frequency trading, and virtualized core storage.

1. Core features and specifications

Capacity: 240 Gigabytes (GB)

This is a common capacity point for early high-performance NVMe SSDs, mainly aimed at application scenarios where performance is maximized rather than capacity expansion.

Interface and Protocol: NVMe 1.1 over PCIe 3.0 x4 Lanes

At the time of release, it provided breakthrough performance, achieving ultra-low latency and high bandwidth of PCIe direct connection for the first time at an enterprise scale.

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 1300 MB/s

Random read IOPS (4K): up to 750000

Random write IOPS (4K): up to 130000

Note: Even by today's standards, its random read and write IOPS performance is still very impressive, especially the random read IOPS.

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, 240GB * 3.0=720GB of data can be written daily, demonstrating its extremely durable design.

TBW (maximum number of bytes that can be written): 1.31 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 extremely high durability and performance consistency, suitable for high-performance enterprise applications.

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 Gen9 servers, achieving out of the box compatibility and optimized performance.

3. Typical application scenarios

This NVMe SSD is designed specifically for applications that require extreme performance:

High frequency trading system: A financial trading environment that requires extremely low latency and ultra-high IOPS.

Core database acceleration: Ultimate performance acceleration for critical databases such as Oracle RAC and SQL Server.

Virtualization Core Storage: Provides the highest performance storage support for virtualized environments.

High performance computing: scientific computing and engineering applications that require ultimate IO performance.

4. Compatibility

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

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