The Foundational Hypervisor for Cloud-Era Infrastructure

Sangfor aSV Hypervisor

Sangfor aSV is a next-generation hypervisor purpose-built for modern IT infrastructure. As the core virtualization engine powering Sangfor HCI, VDI, and Sangfor Cloud, aSV delivers a secure, high-performance, and reliable foundation for compute virtualization. Sangfor aSV supports mission-critical workloads with enterprise-grade virtualization and seamless integration across Sangfor’s full-stack cloud ecosystem—making it a strong choice for modern IT infrastructure.

Architecture Overview

Sangfor aSV is built on a type-1 bare-metal virtualization architecture using KVM as its core engine. It runs directly on physical servers without requiring a host OS, ensuring minimal overhead and maximum performance. Key architectural highlights include:

  • Kernel-level virtualization with enhanced security hardening
  • Decoupled and containerized services for modular upgrades and hot patching
  • Support for x86
  • Integrated with Sangfor’s SFFS clustered file system for high-performance shared storage

This architecture enables aSV to deliver consistent, scalable, and resilient virtualization services across diverse deployment scenarios.
