Compatibility The devices have broad compatibility, supporting a wide range of systems and applications.
Transmission Speed The transmission speed is relatively slower, gradually unable to meet the demands of high-performance applications.
Size The physical size is relatively large, corresponding to 3.5-inch drive bays.
CPU
- Servers typically adopt a dual-processor design, supporting two CPUs of the same platform.
- Intel
- Platinum
- The Platinum series often offers the highest performance, suitable for tasks requiring extreme computational power, such as advanced analytics, machine learning, and AI workloads.
- Gold
- The Gold series provides improved 4-socket performance, built-in workload acceleration, and advanced security technologies, optimized for demanding mainstream data centers, cloud computing, networking, and storage workloads.
- Silver
- The Silver series delivers essential performance and efficiency for entry-level data center computing, networking, and storage.
- Bronze
- The Bronze series offers hardware-enhanced reliability, availability, and serviceability for small businesses and basic storage servers.
- EPYC (AMD's Ryzen Threadripper for servers)
- Core Count
- Different EPYC processor models have varying core counts, ranging from 8, 16, 32, to 64 cores.
- Thread Count
- The thread count typically corresponds to the core count, for instance, an 8-core processor may have 16 threads.
- Base Clock and Turbo Boost
The base clock speed is the fundamental operating frequency of a processor, while Turbo Boost is the automatically elevated frequency when higher performance is required. Processors of different models have varying base clock and Turbo Boost speeds.
DDR
- Also known as DIMM, typical platforms offer 24 slots, with each slot supporting up to 128GB, depending on the server's parameter configuration.
DDR4
- The most common type of RAM used in servers, typically with frequencies of 2133, 2400, 2666, and others. The maximum supported frequency depends on the server platform.
DDR5
- The next-generation memory standard, primarily used in Intel's second-generation and later server platform architectures. DDR5 offers higher bandwidth and transfer rates, with starting frequencies typically at 4800MHz and above.
SLDDR
- Advantages: Low-power RAM suitable for specific customers.
- Disadvantages: Slower data transfer speed and relatively lower performance.
ECC
- Advantages: Provides error checking and correction functionality, enhancing data reliability, suitable for applications requiring high data accuracy such as servers and workstations.
- Disadvantages: Relatively higher price, approximately 20% more expensive than regular RAM.
REG
- Advantages: Adds registers on top of ECC, improving memory stability and compatibility, supporting larger capacities.
- Disadvantages: Price is about twice as high as regular RAM, with slightly higher latency, affecting performance slightly.
RECC
- Advantages: An abbreviation for REG ECC, sharing similar advantages as REG ECC, including error checking and correction functionality, while supporting larger capacities.
- Disadvantages: Higher price, slightly higher latency, requiring support from server motherboards and may not be usable on regular motherboards.
Here is the English translation of the provided server hardware-related text about GPUs, motherboards, and network cards:
GPUs
GPUs typically require newer platform architectures in servers to fully utilize their computational advantages. Such platforms are often in the 4-6U size range.
Nvidia-A100
-
- Features high bandwidth, high computational power, and low latency, suitable for artificial intelligence, deep learning, scientific computing, and more.
Nvidia-A800
-
- A replacement product for the A100, mainly reducing the NVLink transfer rate from 600GB/s of the A100 to 400GB/s, while other parameters remain largely the same.
- A special version with slightly reduced performance compared to the A100.
-
A40, A30, L20, L4, etc.
-
- Alternative versions with lower prices, depending on the customer's configuration scheme and needs.
- Suitable for graphics processing, virtual reality, film post-production, inference, deep learning training, and high-performance computing.
- Consideration should be given based on specific requirements and application scenarios.
-
Nvidia-RTX4090
-
- Boasts extremely high computational and graphics processing capabilities, capable of handling complex computational tasks and graphics rendering needs.
- Can be used for some AI-related tasks, such as deep learning inference.
- Not specifically optimized for servers: Compared to dedicated server-grade GPUs, it may have slightly inferior adaptability and stability in certain server-specific scenarios.
Motherboards
- Each generation of equipment platforms is built on an entirely new platform architecture based on the motherboard, and the price of a new platform is often very high.
Network Cards
When it comes to server hardware, there are several key components and features to consider:
Network Interface Cards (NICs): Commonly available in dual-port, quad-port, or other configurations, NICs can offer 4×1GE electrical ports or 2×10GE electrical/optical ports, depending on the customer's requirements.
Cooling: Modular fans are typically used for cooling, and for high-end computing equipment, immersion cooling solutions may be employed to effectively dissipate heat.
RAID Cards: Also known as array cards, RAID cards primarily serve to protect data. In certain RAID levels, such as RAID 1 and RAID 5, even if some disks fail, the integrity and availability of data are still guaranteed.
Power Supplies: Common 2U rack-mounted servers often feature 1+1 modular power supply units that allow for hot-swapping. Power supplies come in different ratings, including Titanium and Platinum.
- Titanium: High-efficiency power conversion, suitable for high-performance servers requiring stable power output of 2000w, 3000w, and more.
- Platinum: Commonly rated below 1100W, with modular versions available in 550w, 750w, and other ratings. These also support hot-swapping.
Rails: Sliding rails, also known as server rails, are used to securely mount servers within a rack.
Core Switches: Core switches are crucial devices in a network architecture, typically operating at the third layer. One or two core switches are commonly deployed per rack.
- Functionality: Core switches support VLAN partitioning, link aggregation, routing protocols, and other features to enable fast communication between different network segments and ensure stable network operation.
- Size: Core switches typically have a large number of ports, with common configurations including 24-port (1-2U) and 48-port (2-3U) models.
- Ports: Optical ports are also available on core switches, providing high-speed, long-distance connectivity options.
