Server RAM: Different types, technologies and best practices

Enterprises try to strengthen their IT infrastructure by understanding the crucial role that servers play in ensuring optimal performance, reliability and scalability. Whether a small business server or large-scale data center, securing optimal levels of server memory is important for building seamless business operations.

Let’s explore the different types of server memory, cutting-edge technologies, and best practices for choosing the right RAM for server-specific needs.

What is server memory?

Server memory, also known as Random Access Memory (RAM), is a form of short-term storage where data is temporarily kept while the server processes tasks. 

Unlike permanent storage (i.e., hard drives or SSDs), RAM provides lightning-fast access to data. The differentiators between RAM and other permanent storage include:

• Speed: RAM is significantly faster than storage memory. 
• Capacity: The amount of RAM directly impacts your server’s performance. The more system RAM, the better the ability to multitask and respond.
• Temporary storage: RAM holds data temporarily, allowing the CPU to quickly access it during active operations.

Different types of server memory

• Buffered RAM (Registered RAM): Buffered RAM, also known as Registered RAM, offers enhanced stability and reliability. It reduces electrical load on the memory controller by using a buffer to receive information directly from the CPU.

Several variants of Buffered RAM include:

• Registered Dual In-line Memory Module (RDIMM): Commonly used in servers, RDIMMs provide stability and error correction.
• Load-Reduced DIMM: LRDIMMs offer even greater capacity and lower power consumption.
• Fully Buffered DIMM: FBDIMMs are less common now compared to older server architectures.
• Unbuffered RAM (Unregistered RAM): Unbuffered RAM  is simpler than buffered RAM but has a higher electrical load.

Unbuffered RAM is available as:

• Dynamic RAM (DRAM): The standard type of RAM used in most consumer devices.
• Static RAM (SRAM): Faster and more expensive than DRAM, SRAM is often used in cache memory.

Different server memory technologies

• Error-Correcting Code (ECC) Memory: ECC memory is designed to identify and correct errors in data. It’s an essential component for mission-critical applications where data integrity is paramount.
• Register (Memory Register): Registers act as directories for memory access. They perform read-and-write functions to enhance efficiency. When combined with ECC, registers provide robust error correction.
• Chipkill memory technology: An extension of ECC memory, Chipkill technology allows a server to continue functioning even if an entire memory module fails. It’s a valuable addition for high-availability environments.
• Memory mirroring: This divides memory into two separate channels. If one channel fails, the other continues to operate, increasing protection against data loss.
• Memory protection: Mechanisms control memory access rights. By defining who can read from or write to specific memory areas, you prevent accidental data corruption.

Choose the best server memory

Choosing the right server memory ensures seamless operations, efficient data processing and a solid foundation for your IT infrastructure. When selecting server memory, consider the following factors:

• Cost: Balance your budget with performance requirements.
• Processing load and intent: Understand your system’s workload and intended use.
• Stability and performance: Opt for reliable memory that meets your performance expectations.
• Concurrent users: Consider the number of users accessing the server simultaneously.
