2V0-21.23 Question 397
Single answerYou are configuring a storage cluster in a vSphere environment to optimize resource utilization. The cluster contains multiple datastores with varying capacities and performance characteristics. You want to ensure that virtual machines (VMs) are automatically placed on the most suitable datastore based on space and I/O requirements, while also considering potential future demand. Which feature should you enable and configure to achieve this?
- A
Storage DRS (Datastore Cluster) with I/O and space balancing
- B
Storage vMotion to manually migrate VMs between datastores
- C
vSAN to aggregate local storage into a shared datastore
- D
Datastore Heartbeating in High Availability (HA) settings
Show answer and explanation
Correct answer: A
Explanation
To optimize resource utilization in a datastore cluster, Storage DRS (Datastore Cluster) with I/O and space balancing should be enabled. This feature automatically places VMs on the most suitable datastore based on current and predicted resource requirements, ensuring efficient use of storage resources. Other features, such as Storage vMotion and vSAN, do not offer the required automation and balancing capabilities for this scenario.
- A. Correct.
Storage DRS with I/O and space balancing is the correct feature for dynamic placement and load balancing of virtual machines across a datastore cluster. This ensures optimal utilization of storage resources while addressing both space and I/O demands.
- B. Incorrect.
Storage vMotion allows the manual migration of VMs between datastores but does not provide automated balancing or placement based on requirements, making it unsuitable for the scenario.
- C. Incorrect.
vSAN is used for aggregating local storage into a single shared datastore but does not perform dynamic placement or balancing of VMs across multiple datastores based on I/O and space.
- D. Incorrect.
Datastore Heartbeating is a feature in vSphere High Availability (HA) for monitoring datastore accessibility and does not contribute to VM placement or resource optimization in a storage cluster.
