Question 94

Due to the success of the recently deployed developer-only private cloud solution, a company has a new requirement to increase the cache size and overall capacity of the solution to support an unexpected change in the workload profile and increase the overall performance of the solution.

The current vSAN cluster has the following configuration:

• 6 vSAN Nodes with 2 CPUs (20 cores), 512 GB RAM

• 2 Disk Groups per vSAN node (2 x 400 GB, 6 x 3.84 TB)

• De-duplication and Compression is enabled.

• Encryption is enabled.

• vSAN Total Capacity is: ~112 TB RAID6/FTT=2 (80% utilized)

Following the administrator's recommendations, the service owner agrees to purchase 12 x 800 GB SSDs and 36 x 3.84 TB SSDs to upgrade the vSAN but would like to ensure that during the upgrade the availability of the workloads are not affected.

Which three actions should the administrator take to meet this requirement? (Choose three.)

Remove the old Disk Groups, and create a new Disk Group using all remaining cache and capacity devices.

Migrate all existing workloads to the new Disk Group(s).

Put each vSAN node into maintenance mode using the Ensure Accessibility option.

Remove the old Disk Groups, and claim the original capacity drives equally across the remaining Disk Groups.

Create two new Disk Groups (each with 1 x 800 GB, 3 x 3.84 TB per node) in the vSAN Cluster using the new storage devices.

Create one new Disk Group (with 1 x 800 GB, 3 x 3.84 TB per node) on the vSAN Cluster using the new storage devices.

Correct Answer: C, E, F

To upgrade the vSAN cluster without affecting the availability of workloads, the following actions should be taken: first, put each vSAN node into maintenance mode using the Ensure Accessibility option to ensure that data remains accessible during the upgrade process. Second, create two new Disk Groups in the vSAN Cluster using the new storage devices, which will increase cache and capacity without immediate disruption to existing workload. Finally, create one new Disk Group on the vSAN Cluster using the remaining storage devices, ensuring that all newly available storage is utilized efficiently. By doing this, the upgrade will be carried out with no impact on availability and performance improvements will be achieved.
