2V0-21.23 Question 396
Select 3An administrator is tasked with configuring a storage DRS (SDRS) cluster for a set of datastores in a VMware vSphere environment. The administrator needs to ensure that the cluster can intelligently balance storage I/O load and automatically place virtual machine disks (VMDKs) during deployment. Additionally, the cluster should avoid placing VMDKs for the same VM on the same datastore. Which of the following actions should the administrator take to achieve these requirements?
- A
Enable Storage DRS and configure it in Fully Automated mode.
- B
Set the 'Datastore Affinity' rule to 'Keep VMDKs together' for the virtual machines.
- C
Enable the 'I/O Metric' option in the Storage DRS cluster settings.
- D
Set the 'Datastore Affinity' rule to 'Keep VMDKs on separate datastores' for the virtual machines.
- E
Disable the 'Space Utilization' threshold setting in the Storage DRS cluster.
Show answer and explanation
Correct answers: A, C, D
Explanation
To achieve the requirements, the administrator must enable Storage DRS in Fully Automated mode, which ensures intelligent and automated placement and balancing of virtual disks. Additionally, enabling the 'I/O Metric' option allows the cluster to consider I/O load, ensuring balanced performance. Finally, configuring the 'Datastore Affinity' rule to 'Keep VMDKs on separate datastores' ensures proper distribution of VMDKs for the same VM across datastores, which avoids potential storage bottlenecks and improves fault tolerance.
- A. Correct.
Enabling Storage DRS in Fully Automated mode allows the system to automatically balance storage resources and handle VMDK placement without manual intervention. This is necessary to meet the requirement of automated balancing.
- B. Incorrect.
Setting the 'Datastore Affinity' rule to 'Keep VMDKs together' would place all VMDKs of the virtual machine on the same datastore, which contradicts the requirement to avoid placing VMDKs for the same VM on the same datastore.
- C. Correct.
Enabling the 'I/O Metric' option ensures that Storage DRS considers I/O load when making placement and balancing decisions, which is required to balance storage I/O load effectively.
- D. Correct.
Setting the 'Datastore Affinity' rule to 'Keep VMDKs on separate datastores' ensures that VMDKs for the same VM are placed on different datastores, meeting the requirement to avoid placing them on the same datastore.
- E. Incorrect.
Disabling the 'Space Utilization' threshold would prevent Storage DRS from considering space usage when balancing workloads, which is not relevant to the requirements and could hinder cluster performance.
