Product overview for the HPE 726719-B21

In the ever-evolving landscape of server technology, having the right memory modules is crucial for optimal performance. One such module that stands out is the HPE 726719-B21 16GB DDR4-2133MHz SDRAM. In this detailed guide, we will delve into the specifications, features, and applications of this memory module designed specifically for HPE ProLiant G9 servers.

Understanding the Basics DDR4-2133MHz SDRAM

DDR4, or Double Data Rate 4, is the fourth generation of synchronous dynamic random-access memory (SDRAM) and is widely used in modern computing systems. The 2133MHz indicates the data transfer rate, meaning this memory module can transfer data at a speed of 2133 million cycles per second. This high speed is especially beneficial for servers that require quick and efficient data processing.

ECC Registered and 2Rx4: Ensuring Reliability

The HPE 726719-B21 memory module comes equipped with an Error-Correcting Code (ECC) and is registered. ECC is a crucial feature that helps detect and correct memory errors, ensuring the reliability of data stored in the memory. The "2Rx4" designation signifies that the module has a dual-rank architecture with four banks of memory on each rank. This design enhances data access efficiency and overall system performance.

CL15 and 1.2V: Striking a Balance

The Cas Latency (CL) of 15 is a measure of the time it takes for the memory module to deliver data requested by the CPU. A lower CL indicates faster data access, contributing to improved system responsiveness. The 1.2V operating voltage is a power-efficient feature, aiding in reducing energy consumption and heat generation, which is particularly important in server environments.

288-pin RDIMM Form Factor

The HPE 726719-B21 memory module adopts the 288-pin Registered DIMM (RDIMM) form factor. RDIMMs are known for their robustness and reliability, making them suitable for server applications. The 288-pin configuration ensures a secure and stable connection to the server's memory slots, minimizing the risk of disconnections and data errors.

Compatibility with ProLiant G9 Servers

One of the key highlights of the HPE 726719-B21 memory module is its compatibility with HPE ProLiant Generation 9 (G9) servers. ProLiant servers are renowned for their performance and reliability, and the G9 series is no exception. The memory module is specifically designed to complement the architecture of these servers, ensuring seamless integration and optimal functionality.

Addressing Server Workloads

The 16GB capacity of the HPE 726719-B21 makes it well-suited for handling demanding server workloads. Whether it's data-intensive applications, virtualization, or database management, this memory module provides the necessary capacity to support these tasks efficiently. The ECC feature further enhances its suitability for critical applications where data accuracy is paramount.

Performance and Reliability

The DDR4-2133MHz speed of the HPE 726719-B21 is designed to enhance overall server performance. The high data transfer rate ensures that the server can process and deliver information swiftly, reducing latency and improving response times. This is particularly crucial in environments where quick data access is essential, such as in real-time analytics and transaction processing.

ECC for Data Integrity

The ECC feature plays a pivotal role in maintaining data integrity. In a server environment, where data accuracy is non-negotiable, ECC helps identify and correct errors in the memory. This is especially crucial for mission-critical applications where even minor data discrepancies can have significant consequences. The HPE 726719-B21, with its ECC capability, adds an extra layer of protection to ensure the reliability of stored data.

Dual-Rank Architecture for Efficiency

The 2Rx4 dual-rank architecture contributes to the efficiency of data access. By organizing memory banks into ranks, the module can handle multiple requests simultaneously, reducing queuing times and enhancing overall system responsiveness. This is particularly beneficial in scenarios where the server is tasked with running numerous applications concurrently.

Power Efficiency with 1.2V

The 1.2V operating voltage of the HPE 726719-B21 is not only a measure of power efficiency but also contributes to heat reduction. In a server environment, where temperature management is critical, having memory modules that operate at lower voltages helps in maintaining a cooler system. This can result in more stable long-term performance and can contribute to the overall energy efficiency of the server infrastructure.

Use Cases and Applications

The 16GB capacity and high-speed performance make the HPE 726719-B21 ideal for data-centric applications. From large-scale databases to complex data analytics, this memory module can handle the demands of applications that require rapid access to substantial amounts of data. In scenarios where real-time decision-making is crucial, the module's speed and reliability become invaluable.

Virtualization Environments

Virtualization is a common practice in modern server deployments, allowing for the efficient utilization of hardware resources. The HPE 726719-B21, with its 16GB capacity and dual-rank architecture, is well-suited for virtualization environments. The ability to efficiently manage multiple virtual machines simultaneously is essential, and this memory module provides the necessary capacity and performance for such scenarios.

Mission-Critical Servers

In mission-critical server environments where downtime is not an option, the reliability of components is paramount. The ECC feature of the HPE 726719-B21 adds an extra layer of protection against memory errors, making it a suitable choice for servers handling critical workloads. Whether it's financial transactions, healthcare data management, or enterprise resource planning, this memory module is designed to meet the stringent requirements of mission-critical applications.
