Product overview for the HP 647901-B21

In the ever-evolving landscape of technology, servers play a crucial role in facilitating data storage, processing, and retrieval. A key component that significantly impacts server performance is the Random Access Memory (RAM). This article delves into the details of the HP 647901-B21 16GB DDR3 SDRAM Memory Module, shedding light on its specifications, features, and relevance in server environments.

Overview of HP 647901-B21 16GB DDR3 SDRAM Memory Module

Random Access Memory (RAM) is an integral part of any computing system, including servers. It serves as temporary storage for data that the CPU can quickly access, enhancing overall system performance. In server environments, a robust and reliable RAM module is crucial for handling concurrent processes, supporting virtualization, and ensuring optimal response times.

Introduction to HP 647901-B21 16GB DDR3 SDRAM:

The HP 647901-B21 is a specific RAM module designed for servers. It boasts a 16GB capacity, making it suitable for memory-intensive applications and workloads. As a DDR3 SDRAM module, it adheres to the DDR3 (Double Data Rate 3) standard, a widely used RAM technology known for its efficiency and reliability.

Technical Specifications Memory Type and Capacity

The HP 647901-B21 is a DDR3 SDRAM module, which indicates its adherence to the DDR3 standard. The 16GB capacity makes it suitable for memory-hungry server applications, ensuring smooth operation even under heavy workloads.

Speed and Bandwidth

The module operates at a speed of 1333MHz, denoting the data transfer rate in megahertz. This speed is essential for quick data retrieval and efficient processing, contributing to the overall responsiveness of the server. The PC3-10600 designation refers to the peak bandwidth of the module, indicating its ability to handle data transfer rates of up to 10.6 gigabytes per second.

ECC (Error-Correcting Code) and Registered Design

One notable feature of the HP 647901-B21 is its ECC and Registered design. ECC is a mechanism that detects and corrects errors in data, ensuring data integrity. The Registered design, on the other hand, adds a buffer to the memory module, reducing electrical load and enhancing stability. These features make the module particularly suitable for mission-critical applications where data accuracy is paramount.

Dual Rank Configuration

The memory module is configured as dual rank, signifying the organization of memory chips on the module. Dual-rank modules can provide better performance in certain scenarios, especially when the server motherboard is optimized to take advantage of this configuration.

Low Voltage Operation

The module operates at low voltage, contributing to energy efficiency and reduced heat generation. Low voltage modules are beneficial for maintaining a stable operating temperature within the server, ultimately prolonging the lifespan of both the memory module and the overall system.

240-pin DIMM Form Factor

The 240-pin DIMM (Dual Inline Memory Module) form factor is a standard size for DDR3 modules. This form factor ensures compatibility with a wide range of server motherboards designed to accommodate DDR3 memory.

Use Cases and Server Compatibility Memory-Intensive Applications

The 16GB capacity and high-speed operation of the HP 647901-B21 make it ideal for memory-intensive applications such as virtualization, database management, and content delivery networks. Servers hosting these applications can benefit significantly from the increased memory capacity and quick data access provided by this module.

Server Compatibility

Before upgrading or replacing memory modules, it's crucial to ensure compatibility with the server's existing hardware. The HP 647901-B21 is designed to work seamlessly with servers that support DDR3 memory. System administrators should refer to the server's documentation or consult HP's compatibility lists to verify that the module is suitable for their specific server model.

Benefits of Choosing HP 647901-B21 16GB DDR3 SDRAM

Enhanced Server Performance

The high capacity and speed of the HP 647901-B21 contribute to improved server performance, enabling faster data access and processing. This is particularly advantageous in scenarios where multiple users or applications concurrently access the server's resources.

Reliability and Stability

The ECC and Registered design of the module enhances data integrity and system stability. In mission-critical environments where errors can have severe consequences, the reliability of the memory module is paramount.

Energy Efficiency

The low voltage operation of the HP 647901-B21 not only contributes to energy efficiency but also aids in temperature management within the server. This is crucial for maintaining a stable operating environment and extending the lifespan of server components.
