Number of CPU cores on the hypervisor server when configuring Sangfor HCI

Hello.
As I mentioned in the question, I wonder how many CPU cores are on the hypervisor server when I configure Sangfor HCI.

Do I have to configure my CPU to multiples of 2 (1, 2, 4, 8) Core?
Please let me know if it is okay to configure "6" and "12" Core regardless of the above.

Thank you.

When configuring Sangfor HCI, while it's often recommended to allocate CPU cores in multiples of 2 due to how processors handle threading, allocating 6 or 12 cores can still work within the system. Ensure this allocation aligns with your workload needs and check Sangfor's specific recommendations for their HCI solution. Consider factors like performance optimization, resource allocation, hardware compatibility, and future scalability when determining the ideal core allocation for your setup. If uncertain, consulting Sangfor's support or documentation for tailored guidance based on your deployment specifics can offer more precise recommendations.

Usually HCI platforms are designed to work optimally with configurations  that follows the power of 2 pattern (1, 2, 4, 8, so on...) Virtualization often involves dividing physical resources into smaller units and power of 2 simplify the process.

When configuring Sangfor HCI (Hyper-Converged Infrastructure), it is generally recommended to configure the CPU cores in multiples of 2 (such as 2, 4, 8, etc.). This is because most hypervisors and virtualization technologies are designed to work optimally with an even number of CPU cores.

However, it is possible to configure Sangfor HCI with an odd number of CPU cores, such as 6 or 12 cores, if your specific hardware and hypervisor support it. Modern hypervisors usually have the ability to handle different CPU configurations, including odd numbers of cores. It is important to check the documentation and specifications of your specific hypervisor to confirm its capabilities and any limitations regarding CPU core configuration.

Keep in mind that the performance and efficiency of the HCI environment can be influenced by the CPU core configuration. It is advisable to consult the official documentation, guidelines, or contact Sangfor support for specific recommendations based on your hardware and hypervisor combination to ensure optimal performance and compatibility.

Sangfor HCI, like many other hypervisor-based systems, typically benefits from configurations that align with certain CPU core counts due to the way resources are managed and allocated.

Configuring CPU cores in multiples of 2 (such as 2, 4, 8, 16, etc.) is a common recommendation because most hypervisors allocate resources in pairs, allowing for more efficient resource management and optimization. This alignment often leads to better performance and resource utilization.

However, it's not a strict requirement to configure CPU cores exclusively in multiples of 2. Modern hypervisors and systems can handle odd core counts (like 6 or 12 cores) without significant issues.

When you configure your hypervisor server, consider factors such as workload requirements, the number of virtual machines (VMs) you intend to run, and the specific recommendations provided by Sangfor for their HCI solution.

While multiples of 2 might be the general guideline, using 6 or 12 cores should generally work fine, especially if it aligns better with your hardware capabilities or specific workload needs. Just ensure that the chosen configuration meets Sangfor's minimum system requirements and guidelines for optimal performance. Always refer to their official documentation or support resources for the most accurate and detailed recommendations for your specific use case.

In many virtualization and hyper-converged infrastructure (HCI) environments, including Sangfor HCI, the convention of configuring CPU cores in multiples of 2 (1, 2, 4, 8, etc.) is often recommended for optimal performance. This is because many virtualization technologies are designed to work efficiently with symmetric multiprocessing (SMP), where the number of virtual CPUs is a power of 2.

modern hypervisors and virtualization platforms have become more flexible, and some can handle configurations with a non-power-of-2 number of CPU cores. While it's generally best practice to stick to multiples of 2 for simplicity and compatibility, some hypervisors can work with configurations like 6 or 12 cores.

For specific guidance on configuring the CPU cores for Sangfor HCI, I recommend checking the official Sangfor documentation, as it should provide detailed information on the supported configurations and best practices. The documentation may specify whether it's acceptable to configure CPUs with a non-power-of-2 number of cores and any considerations or limitations associated with such configurations.

If you cannot find the information you need in the documentation, consider reaching out to Sangfor support directly for clarification and guidance tailored to your specific deployment scenario. They should be able to provide you with the most accurate and up-to-date information based on the current version of the Sangfor HCI software.

For best performance, it is common practice in many virtualization and hyper-converged infrastructure (HCI) settings, including Sangfor HCI, to configure CPU cores in multiples of two (1, 2, 4, 8, etc.). This is because symmetric multiprocessing (SMP), in which the number of virtual CPUs is a power of two, is intended to be compatible with numerous virtualization approaches.
