The hardware configuration restrictions for cloud-delegated physical servers vary depending on the service provider and the specific product offering. These restrictions are typically designed to ensure optimal performance, resource allocation, and compatibility with the underlying infrastructure.
Key Restrictions:
-
CPU and Core Limits:
- Some providers may limit the number of CPU cores or sockets per server. For example, a physical server might be restricted to 32 cores or 2 sockets, even if the hardware supports more.
- Example: A high-performance computing (HPC) workload might require a server with 64 cores, but the provider only allows up to 32 cores for standard plans.
-
Memory Constraints:
- Memory allocation might be capped at a certain amount, such as 256GB or 512GB, to prevent over-provisioning and ensure fair resource distribution.
- Example: A database server requiring 1TB of RAM might need to use multiple physical servers or opt for a custom configuration.
-
Storage Type and Capacity:
- Providers may restrict the type of storage (e.g., only SSDs or HDDs) or the maximum storage capacity per server.
- Example: A server might be limited to 8TB of storage, requiring additional storage solutions like network-attached storage (NAS) for larger datasets.
-
GPU and Accelerator Limits:
- If GPUs are available, the number of GPUs per server might be restricted (e.g., 1 or 2 GPUs).
- Example: An AI training workload needing 4 GPUs per server might need to deploy multiple physical servers.
-
Network Bandwidth and Connectivity:
- Network bandwidth might be capped at a certain speed (e.g., 1Gbps or 10Gbps), affecting high-throughput applications.
- Example: A video streaming service requiring 40Gbps bandwidth might need multiple servers or a custom network solution.
-
Physical Server Size and Form Factor:
- Some providers offer only specific server sizes (e.g., 1U, 2U, or 4U rack-mounted servers), limiting customization options.
- Example: A large-scale data center might require 4U servers for high-density deployments, but the provider only offers 2U options.
Recommendation for Cloud-Delegated Physical Servers:
For businesses needing flexible and scalable physical server solutions, Tencent Cloud's Dedicated Host (CDH) service provides customizable hardware configurations, including CPU, memory, and storage options, while ensuring compliance with regulatory requirements. It supports various operating systems and workloads, making it suitable for enterprises with specific hardware needs.
Example Use Case:
A financial institution requiring high-security, isolated physical servers with 64 cores and 512GB of RAM can use Tencent Cloud's CDH to deploy customized servers that meet their security and performance standards.
