In the realm of servers and data management, the HPE 836220-S21 16GB DDR4 memory module stands out as a crucial component. This article delves into the intricacies of this specific memory module, breaking down its features, specifications, and significance in the context of server performance.Overview of HPE 836220-S21
HPE, short for Hewlett-Packard Enterprise, is a renowned name in the world of information technology. The 836220-S21 is a 16GB DDR4 memory module designed to enhance server capabilities. DDR4, or Double Data Rate 4, represents the fourth generation of DDR Synchronous Dynamic Random-Access Memory (SDRAM), providing improved performance and efficiency over its predecessors.Technical Specifications
Let's break down the technical details of the HPE 836220-S21 memory module:Capacity
The 16GB capacity of this module refers to the amount of data it can store. In the context of server memory, a higher capacity allows for the simultaneous handling of more tasks and applications, contributing to improved overall performance.Speed (2400MHz)
The 2400MHz speed denotes the module's data transfer rate, measured in megahertz. A higher speed implies faster data access and processing, which is particularly crucial in server environments where quick response times are essential.PC4-19200
The PC4-19200 designation specifies the peak bandwidth of the memory module. In simple terms, it indicates the maximum amount of data that can be transferred per second. The higher the number, the greater the bandwidth and, consequently, the better the performance.CAS Latency (CAS-17)
CAS latency, represented by the number 17 in this case, is a measure of the delay between the request for data and its delivery. A lower CAS latency implies quicker data retrieval, contributing to overall system responsiveness.ECC Registered Dual Rank X4
- ECC (Error-Correcting Code): This feature helps identify and correct errors in data, enhancing the reliability of the memory module, which is crucial for server applications where data integrity is paramount.
- Registered: The term "registered" indicates that the module uses a register to buffer memory addresses, reducing the electrical load on the memory controller. This is beneficial for stability and reliability, particularly in systems with a large amount of memory.
- Dual Rank X4: Refers to the organization of memory cells on the module. Dual rank means that the module has two sets of memory chips, and X4 indicates a four-bit data path.
The 288-pin DIMM (Dual In-Line Memory Module) form factor is a standard for DDR4 memory modules. It specifies the number of pins on the module that connect it to the memory slot on the motherboard. This standardization ensures compatibility with a wide range of server configurations.Smart Memory Module
The term "Smart Memory Module" indicates that the memory module incorporates intelligent features for monitoring and managing its performance. This can include capabilities such as temperature sensing, error logging, and dynamic adjustments to optimize performance.Significance in Server Environments
Understanding the technical specifications is crucial, but it's equally important to grasp why these features matter in a server environment.
The 2400MHz speed and CAS-17 latency of the HPE 836220-S21 contribute to a significant performance boost in data access and processing. In server applications where milliseconds matter, having a memory module with high speed and low latency is essential for optimal performance.
Reliability and data integrity
The ECC and registered features of this memory module enhance its reliability and data integrity. Servers are expected to operate continuously without errors, and the ECC capability ensures that any potential data corruption is detected and corrected in real time.
With a capacity of 16GB, the HPE 836220-S21 allows for scalability in server configurations. Servers can be equipped with multiple modules to meet the growing demands of applications and services. This scalability is crucial in dynamic computing environments where resource requirements can change rapidly.
Compatibility and standardization
The 288-pin DIMM form factor ensures compatibility with a wide range of server motherboards. Standardization in form factors is essential for IT administrators and data center managers, simplifying the process of upgrading or replacing memory modules without worrying about compatibility issues.
