这题肯定选d啊。

Storage I/O Control
When you enable Storage I/O Control, ESXi monitors datastore latency and throttles the I/O load if the datastore average latency exceeds the threshold.

Storage DRS
Storage DRS allows you to manage the aggregated resources of a datastore cluster. When Storage DRS is enabled, it provides recommendations for virtual machine disk placement and migration to balance space and I/O resources across the datastores in the datastore cluster.

看题目自然选择vSphere Storage DRS

D Storage I/O Control只简单的限制IO，vSphere Storage DRS实现Datastore间的IO和使用空间的负载均衡

D是正解

肯定人是D 不用懷疑  Storage I/O Control 不做 distribute space usage
