In this comprehensive guide, we will delve into the key aspects of this memory module, breaking down its specifications, features, and applications in simple English.
Overview of HPE 809080-091
The HPE 809080-091 is an 8GB DDR4 Smart Memory Module designed specifically for servers. Let’s break down the product name to understand its specifications better:
- Capacity: 8GB – This denotes the amount of data the memory module can store, and in this case, it’s 8 gigabytes.
- Type: DDR4 – This refers to the fourth generation of Double Data Rate Synchronous Dynamic Random-Access Memory, which is the standard for modern computer memory.
- ECC (Error-Correcting Code): Yes – ECC is a feature that helps detect and correct errors in data, enhancing the reliability of the memory module.
- Speed: 2400MHz – This indicates the speed at which the memory can transfer data, measured in megahertz (MHz).
- CAS Latency: 17 – CAS (Column Address Strobe) latency is the time delay between the moment a memory controller tells the memory module to access a particular column in a row and the moment the data from the given column is available.
- Registered: Yes – Registered memory, often used in servers, includes a register between the RAM and the memory controller. This provides additional stability and reliability.
- Rank: Single Rank – This refers to the organization of memory chips on the module. Single Rank modules have memory chips on one side, which can affect performance in certain scenarios.
- X8: This indicates that the memory module uses x8 (eight bits) organization. It is a common organization for server memory.
DDR4 SDRAM and Its Significance
DDR4 Synchronous Dynamic Random-Access Memory (SDRAM) is the latest standard in DDR SDRAM, succeeding DDR3. The ‘4’ in DDR4 indicates that it is the fourth generation of this technology. DDR4 brings several improvements over its predecessor, including higher data transfer rates, lower power consumption, and increased module density.
Significance of DDR4 in Server Environments
In a server environment, where multiple tasks are performed simultaneously and data processing demands are high, having a reliable and efficient memory system is paramount. DDR4 SDRAM contributes to enhanced server performance by providing faster data access and transfer rates. The 2400MHz speed of the HPE 809080-091 ensures that data can be processed quickly, supporting the demanding requirements of server applications.
ECC and Its Role in Data Integrity
Error-Correcting Code (ECC) is a mechanism incorporated into certain types of memory, including the HPE 809080-091, to detect and correct errors that may occur during data storage or retrieval. In a server environment, data integrity is of utmost importance. ECC helps prevent and rectify errors that could potentially lead to system crashes or data corruption.
Importance of ECC in Servers
Servers often handle critical tasks and store sensitive data. The occurrence of even minor errors in the memory can have significant consequences. ECC provides an additional layer of protection by identifying and fixing errors in real-time, ensuring that the data stored and processed by the server remains accurate and reliable.
CAS Latency and Its Impact on Performance
CAS latency, represented by the number following “CAS” in the product name (CAS-17 in the case of HPE 809080-091), is a crucial factor in memory performance. It measures the time delay between the memory controller requesting data and the data being available. A lower CAS latency generally indicates better performance.
Optimizing Server Performance with CAS-17
In a server environment, where quick access to data is essential for seamless operations, a CAS latency of 17 ensures that data retrieval is efficient. The HPE 809080-091 strikes a balance between speed and latency, making it well-suited for a variety of server applications.
Registered Memory for Stability
Registered memory, denoted by the “Registered” feature in the HPE 809080-091, includes a register between the RAM and the memory controller. This register buffers the control signals, enhancing stability and reliability. Registered memory is commonly used in servers where reliability is a top priority.
Stability in Server Environments
Servers operate around the clock, handling numerous requests and data transactions. Any instability in the memory system can lead to system crashes or data loss. The use of registered memory, as exemplified by the HPE 809080-091, adds a layer of stability, ensuring that the server performs consistently under varying workloads.
Single Rank Configuration and Its Implications
The term “Single Rank” in the product description indicates how the memory chips are organized on the module. In a Single Rank configuration, all the memory modules are on one side of the module, while dual-rank modules have memory chips on both sides. The choice between Single Rank and Dual Rank depends on specific system requirements.
Single Rank and Server Performance
Single Rank modules, like the HPE 809080-091, can offer advantages in certain scenarios. They may provide better performance in applications that are sensitive to memory access speed. However, the optimal choice between Single Rank and Dual Rank depends on the server’s architecture and the nature of the tasks it performs.
X8 Organization for Efficient Data Handling
The “X8” in the product name signifies the organization of the memory chips on the module. In an x8 organization, each memory chip is 8 bits wide. This organization is a common choice for server memory modules.
Efficient Data Handling in Servers
Efficient data handling is crucial for server performance. The x8 organization in the HPE 809080-091 ensures that data can be processed in chunks, optimizing the flow of information between the memory module and the server’s memory controller.
Compatibility and Gen9 Support
The HPE 809080-091 is specifically designed for Gen9 servers. Gen9 refers to the ninth generation of HPE ProLiant servers. Ensuring compatibility with the server generation is essential for seamless integration and optimal performance.
Gen9 Support for Advanced Features
Gen9 servers typically come with advanced features and technologies. The HPE 809080-091 is engineered to complement and leverage these features, providing a memory solution that aligns with the capabilities of Gen9 servers.
