Overview
A QingTian ECS server consists of a host system and QingTian Cards.
- QingTian Cards are dedicated hardware components that run independently from the host system.
- The host system consists of the host CPU and memory, and runs customer's ECS VM instances or bare metal instances.
QingTian Cards and the host system are connected through the PCIe bus. They belong to two completely isolated system security domains.
