An Overview Of Server Memory Types

To perform efficiently, every server or computer system requires sufficient RAM to store and manage its database. Computer Servers often require high-performing memory to be able to cater to intensive workloads and run multiple applications simultaneously. There are several types of server memory designed to process and store data for all kinds of processors.

What is Server Memory?

Server Memory is the Random Access Memory (RAM) which helps with processing data from hard drives to the CPU. Server memory is a volatile memory which means that it stores the information temporarily, once the system is powered off it loses all of its stored data. Server memory can be explained as short-term memory, whereas HDDs are long-term memory modules.

Furthermore, server memory offers fast read-up and write speed and is comparatively faster than the storage memory. Also, it allows the CPU to access them directly from server RAM without having to browse through hard drives for any instructions.

How Does Server Memory Work?

Server Memory is volatile memory, which can store data temporarily only and loses all the stored data once the power is turned off. The RAM is mounted on the motherboard in DIMM (Dual In-line Memory Module) or RAM sticks so when the application is processed, the data is loaded to RAM from SSD or HDD then the processor accesses this data to process it by using instructions. To be more specific, the role of RAM is to store information with the instruction given by the CPU which makes the data accessible anytime without any hassle or interruptions.

What are the types of Server Memory?

The types of memory used by the servers are being upgraded from DRAM (Dynamic Random Access Memory) to SDRAM (Synchronous Dynamic Random Access Memory), over the years. These new types of server memory are synchronized with the processor’s clock rate and processing speed. With these variations in speed and capacities, each type is designed specifically for certain tasks; such as

Buffered RAM

Registered RAM or Buffered Memory is the additional chip that enhances communication between the CPU and the memory module chips. Every stick of RAM consists of several chips on it that transmit and communicate signals directly from the CPU. However, these buffered memory chips help with minimizing the number of signals sent by the CPU. This server memory is specifically used for high-end systems that require a stable working environment that enhances workload efficiency. One of the biggest advantages of this memory is that it receives signals sent directly by the CPU which also reduces the physical read-up and write-up speed. Also, there are three types of buffered memory including RDIMM, LRDIMM, and FBDIMM.

Unbuffered RAM

Unbuffered Memory or unregistered memory enables that CPU to have direct access to the controller as there are no registers in between DRAM modules and the memory controller. This type of memory is usually used for laptops, desktops, or small servers as it is relatively less reliable than buffered memory. Further, this memory enables the CPU to have direct contact with the individual memory banks, which means that the CPU sends the information to each stick of RAM individually to process the data.  However, this memory brings more flexibility and has more room for expansion but they certainly require more energy to process the data which leaves little to no less headroom for the CPU to perform other tasks simultaneously. Also, this server memory is less pricey than buffered RAM.

ECC RAM

ECC (Error-correcting and checking) RAM is most essential when a large amount of data is concerned with little to no tolerance for data corruption. This technology basically helps with identifying any kind of errors and also corrects them. This identification and correction of errors enhance the data reliability and security as a single bit error can lead to the delivery of wrong information which can later cause bottlenecks for the server and may also cause program failure. However, this risk of data loss or program failure can be minimized by using ECC memory.
