Summary of Server and Network Equipment Products

SSD

• Servers typically support up to 8-12 3.5-inch hard drives or 24 2.5-inch hard drives, depending on customer requirements and server capabilities.

U.2

• High performance, with extremely fast read and write speeds
• Supports multiple queues and higher IOPS
• Relatively high cost
• Popularity needs to be further improved

SAS

• Good compatibility, downward compatible with SATA
• Suitable for enterprise-level applications, high stability
• Higher price
• Relatively complex equipment and cables

M.2

• Compact size, does not occupy too much space, not often chosen for server platforms
• Fast transfer speeds, especially M.2 with NVMe support performs exceptionally well
• Potential for heating issues, requiring good heat dissipation measures
• Relatively limited capacity: While capacity is continuously increasing, high-capacity options can be costly compared to some traditional hard drives

SATA

• Mature technology, low price

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

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.

• 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.

• Advantages: Low-power RAM suitable for specific customers.
• Disadvantages: Slower data transfer speed and relatively lower performance.

• 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.

• 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.

• 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.

• • Features high bandwidth, high computational power, and low latency, suitable for artificial intelligence, deep learning, scientific computing, and more.
