What is RAM Server? RAM Server, also known as server RAM, is an indispensable component in the server system. It plays an important role in temporarily storing data and supporting the operation of applications as well as ensuring performance and running on the server. The following article from VinaHost will provide detailed information about the important role of RAM Server in server operation.

1. What is Server Ram?

Server RAM is an important component in computers and especially servers. Usually integrated in the server operating system or server system, server RAM plays a role in determining the number and size of programs that can run or process simultaneously.

It also affects the ability to transmit and process data immediately. It can be said that a RAM server acts as a decisive factor, similar to the heart, for the server system. This is an aspect that cannot be ignored when building a server system for a business.

2. How does Server Ram work?

Hamming code is a simple method of handling data errors. It involves rearranging the data segment to create a new segment, then using parity bits to check for errors. In case of error detection, error correction bits determine the exact location of the error in the data.

Hamming code is capable of correcting errors in one or two bits, depending on its version (traditional or with an additional error correction bit – SECDED). A notable advantage of Hamming code is that the ratio of data bits to total bits increases as the data size increases.

In contrast, Triple Modular Redundancy (TMR) uses a simpler implementation method. Each bit of data is stored three times, then all three bits are read, with the assumption that two of the three bits have the same value. This helps control errors, with the data bit rate and total number of bits always maintaining a one-third relationship.

3. Types of Server Memory Ram?

3.1. Buffered RAM

Buffered memory (also known as registered memory) is designed to reduce the electrical load on the server’s memory controller. It is commonly used in servers and other high-end systems to ensure stable operation due to high data stability.

The main benefit of buffered RAM is the ability to receive information directly from the CPU, reducing actual read and write times. There are three main types of buffered memory: registered memory (RDIMM), offload memory (LRDIMM), and full buffered memory (FBDIMM).

3.1.1. RDIMM

This type of memory has registers on the DIMM to buffer command signals between DRAM and the memory controller. This allows the use of up to three dual-rank DIMMs per memory channel, increasing the server’s memory capacity.

3.1.2. LRDIMM

This is a newer version of buffered memory. It provides greater memory capacity by using memory buffers to consolidate electrical loads across DIMM levels into a single electrical load. However, LRDIMM consumes more power and has lower latency than RDIMM.

3.1.3. FBDIMM

This is an older caching technology used to increase the speed, stability, and compatibility of server memory. FBDIMM and LRDIMM are not compatible with RDIMM and are used to reduce the load on the memory bus.

3.2. Unbuffered RAM

Unbuffered RAM (UDIMM) does not have buffers and registers on the memory module, but instead resides directly on the Mainboard. This type automatically detects and corrects errors. Access commands are sent directly to the memory module without passing through any registers. Choosing between Unbuffered RAM and Registered RAM depends on the specific needs and requirements of the system.

4. Key Features of Server RAM

4.1. Error-Correcting Code (ECC)

ECC (Error-Correcting Code) is an important component in the server system, including 2 main types: Registered ECC and Unbuffered ECC. ECC helps detect and correct errors in data, providing system stability and reliability.

4.2. Registered DIMMs (RDIMMs) and Load-Reduced DIMMs (LRDIMMs)

RDIMM: This type of RAM has registers on the DIMM that help buffer command signals between the DRAM and the memory controller. This design allows the use of more DIMMs per memory channel, increasing the overall memory capacity of the server. RDIMMs are famous for their reliability and stability in high load environments.
LRDIMM: This is a more advanced type of RAM that uses cache memory to reduce the power load on the memory controller. This helps support larger memory capacities. LRDIMMs are ideal for memory-intensive servers, although they consume more power and may have slightly higher latency than RDIMMs.

4.3. Capacity and Speed Considerations

Capacity refers to the capacity of RAM, and also the amount of information that RAM can store. Different types of RAM (for example: 64GB RAM, 128GB RAM) will have different capacities, suitable for the user’s needs.

Memory speed affects the speed at which the CPU can access and process data. Faster memory speeds improve server performance, reduce latency, and improve the efficiency of data-intensive tasks. When choosing server RAM, it’s important to balance capacity and speed to meet the specific needs of your application and workload.
