In Huawei FusionCompute, which of the following factors does DRS perform virtual machine migration? (Multiple choices)

Question

Options

• AMemory
• BI/O
• CNetwork traffic
• DCPU

• A
  71% (35)
• B
  16% (8)
• C
  12% (6)

Explanation

Huawei FusionCompute's DRS (Dynamic Resource Scheduling) evaluates CPU utilization and Memory utilization as the primary indicators of host load imbalance, triggering live VM migration (via vMotion-equivalent) to redistribute workloads and keep cluster resources balanced. These two compute-plane metrics directly reflect whether a host is overloaded or underutilized, making them the natural levers for scheduling decisions.

Why B (I/O) and C (Network traffic) are wrong: FusionCompute DRS operates at the compute resource layer - it does not factor in storage I/O throughput or network bandwidth when deciding whether to migrate a VM. Those metrics may be visible in monitoring dashboards, but they are not DRS trigger conditions in FusionCompute's implementation.

Memory tip: Think "DRS = CPU + RAM" - the two resources a hypervisor directly controls and reallocates by moving a VM to another host. Storage I/O and network traffic are infrastructure-layer concerns handled by separate mechanisms (e.g., storage QoS, network policies), not by the scheduler.
