03GU539 03GU526 compatible with PM1723B enterprise NVMe SSD 15.36TB U.2 hard drive

Product Description

1.Product Overview

03GU539 is a high-performance, high durability enterprise NVMe solid-state drive designed specifically for FlashSystem 9x00 and 7x00 series full flash storage arrays. This hard drive is typically used in the 03GU526 NVMe expansion cabinet (rack) of storage systems as a core component to enhance storage capacity and performance. It’s hardware foundation is the PM1723B enterprise level disk body, which has undergone strict certification and customized firmware debugging to ensure perfect compatibility and reliability with the storage system.

2. Core specification parameters

Project Specification Description

Brand and Model: IBM

Part Number (FRU) 03GU539

Compatibility rack number 03GU526 (for IBM FlashSystem NVMe expansion enclosure)

Disk model Samsung PM1723B

Interface Protocol NVMe 1.3

Physical interface 2.5-inch U.2 (SFF-8639)

Capacity 15.36 TB

NAND flash memory type 3D TLC (Triple Level Cell) NAND

Key features include extremely high durability, NVMe dual port, and enterprise level reliability

3. Performance characteristics

High performance: As an enterprise grade NVMe SSD, its performance far exceeds SATA/SAS interface products, effectively eliminating storage bottlenecks.

Sequential read speed: up to 6500 MB/s

Sequential write speed: up to 4000 MB/s level

Random read and write IOPS: up to millions (specific values are subject to IBM's official specification sheet)

Ultimate durability: This is the core advantage of this drive, designed for 7x24 hour uninterrupted write intensive applications.

DWPD (Daily Full Disk Write Count): up to 10 (meaning 153.6 TB of data can be written per day during the 5-year warranty period)

TBW (lifetime write byte count): up to 28000 TBW

High reliability: MTBF (Mean Time Between Failures) can reach up to 2 million hours, providing extremely high operational stability.

4. Core Technologies and Functions

NVMe dual port access: Supports Active Active dual controller access. This is a key technology for IBM storage arrays to achieve high availability (HA) and redundancy. Two controllers can access the same hard drive simultaneously, and when one path fails, the business automatically seamlessly switches to the other path, ensuring zero interruption.

Power outage protection: Built in comprehensive power outage protection (PLP) circuit. In the event of an unexpected power outage, it can provide sufficient power to the hard drive to fully write the cached data into NAND flash memory, ensuring absolute data integrity and consistency.

Enterprise level data protection: supports end-to-end data path protection, advanced ECC error correction, and comprehensive S.M.A.R.T. attribute monitoring to ensure the security of the entire data link from the host to the NAND grain.

Advanced flash management: equipped with powerful garbage collection (GC), wear leveling, and bad block management algorithms, maximizing hard drive lifespan and maintaining long-lasting performance stability.

5. Application scenarios and compatibility

Main application: This hard drive is a dedicated hard drive for the 03GU526 NVMe expansion cabinet in FlashSystem 9200/9100, 7200 and other series storage arrays, used to expand the original capacity and performance of the storage system.

Typical workload:

Enterprise core databases (Oracle, SQL Server, DB2)

Virtualization and Cloud Infrastructure (VMware, Hyper-V)

High Performance Computing (HPC) and Artificial Intelligence/Machine Learning (AI/ML)

Large scale transaction processing system (OLTP) and data analysis

Compatibility notes: This hard drive is a storage system specific component. Its dual port functionality and customized firmware strongly rely on the underlying support of the storage controller. It is strictly prohibited to use it for non-IBM servers or third-party storage devices, otherwise critical features may not be recognized or enabled, and may even lead to compatibility issues.

6. Management and maintenance

Unified management, monitoring, alerting, and firmware upgrades are required through the Storage Manager suite or system management tools.

All maintenance operations, including replacing the hard drive, should follow the official documentation guidance, and there is usually a clear replacement guide in the system management interface.
