HPE P43169-B21 the Server Memory Kits

The world of computing is vast and continually evolving. One of the key components in ensuring that computers, especially servers, perform efficiently is the memory module. HPE, which stands for Hewlett Packard Enterprise, is a renowned name in the IT industry. They offer a range of computing products and services, including the memory modules we're discussing today. One of their offerings is the HPE P43169-B21 32 Gigabytes (GB) (1x32gb) 2rx4 Double Data Rate 4 (DDR4) 3200MHz PC4-25600 Dual Rank X4 Cl22 288-pin Error correction code (ECC) Registered Dual In-line Memory Module (RDIMM) Smart for Server. Let's dissect this long technical name piece by piece to understand what it signifies.

The Basics Understanding

Before we dive deep, it's essential to clarify what a memory module is. Essentially, a memory module is a small circuit board that houses integrated circuits. It's used to provide RAM (Random Access Memory) for computers and other devices. RAM is the computer's short-term memory, where data is temporarily stored and accessed for immediate use. The more RAM a computer has, the better it can multitask and handle resource-intensive tasks.

Capacity: 32 Gigabytes (GB) (1x32gb)

The capacity of the memory module is one of its most crucial aspects. In this case, the HPE P43169-B21 offers 32 Gigabytes (GB). This is a substantial amount of RAM, especially for server operations. Servers typically require a higher amount of RAM because they handle numerous requests and tasks simultaneously. The (1x32 GB) indicates that this particular module provides the entire 32GB in a single stick or module. This can be beneficial for servers with limited RAM slots as it maximizes the amount of memory you can fit into each slot.

Speed & Type: 2rx4 Double Data Rate 4 (DDR4) 3200MHz PC4-25600

Now, let's talk about speed and type. The 2rx4 hints at the module's structure. It denotes that the module uses a dual-rank configuration, which means the memory chips are divided into two sets, and the memory controller can access them independently. This can potentially offer better performance compared to single-rank modules.

  • The term Double Data Rate 4 (DDR4) specifies the generation of the RAM. DDR4 is the fourth generation and is currently one of the most common types used, known for its improved performance and energy efficiency over its predecessor, DDR3.
  • The 3200MHz refers to the speed of the RAM. In simple terms, it denotes how fast the RAM can read or write data. The higher the MHz, the faster the RAM. To further classify the speed, the module is also labeled as PC4-25600. This is another way to represent its speed and bandwidth.
Configuration: Dual Rank X4 Cl22 288-pin

The Dual Rank X4 again emphasizes the dual rank structure of the module. The Cl22 stands for CAS (Column Address Strobe) latency. It's a metric that gives you an idea of the delays or latency the RAM might have when reading data. Generally, lower CAS latency is better, but it's essential to balance it with other RAM specifications.

Safety & Compatibility: Error Correction Code (ECC) Registered

Memory errors, although rare, can happen. For standard consumer-grade PCs, these errors might not be catastrophic. But for servers where data integrity is paramount, even a tiny error can be detrimental. That's where the Error Correction Code (ECC) comes in. ECC can detect and correct common kinds of data corruption, making it an essential feature for servers.

  • The term Registered indicates that the module has a register between the RAM chips and the system's memory controller. This register helps stabilize the data by temporarily holding it before it's sent to the memory controller, especially beneficial in systems with large amounts of RAM.
Dual In-line Memory Module (RDIMM)

Lastly, the Dual In-line Memory Module (RDIMM) points to the form factor and type of the memory module. RDIMMs are specifically designed for servers and high-performance computing systems. They provide robustness and stability, especially in environments where reliability is crucial.

  • The Smart for Server tagline underscores that this module is tailor-made for server applications. HPE ensures that their modules are optimized for high workloads, ensuring that servers run smoothly and efficiently.
