An administrator is reviewing a virtual machine's storage performance on an ESXi 6.5 host and noticed that it is affecting shared data storage activity on another host. Which should be enabled in orde

Network I/O Control manages network bandwidth, not storage I/O throughput or latency on shared datastores.

Storage I/O Control monitors datastore latency and enforces I/O shares and limits per VM when congestion is detected, preventing one VM's heavy I/O from degrading performance for VMs on other hosts sharing the same datastore. It uses a congestion threshold (default 30ms) to trigger throttling. This directly addresses the cross-host storage contention described in the scenario.

Storage DRS balances VM placement across datastores for space and I/O load but does not throttle in-flight I/O from a misbehaving VM in real time.

vSphere HA provides VM restart capability after host failures and has no mechanism to control or throttle storage I/O.
