A write intensive application has been deployed recently into an All-flash 4-node vSAN cluster. Each node has one disk group with the following configuration:
• 1 x 400 GB SSD for Cache
• 4 x 3.84 TB SSD for Capacity
After the deployment, the administrator notices that the overall workload performance is degraded and observes a low-write, buffer-free percentage.
Which action should be taken to remediate this issue?
- A.Adding a second cache disk to the existing disk group
- B.Replacing the cache disk in the existing disk group with a larger one
- C.Enabling automatic rebalance from the vSAN services advanced options
- D.Increasing the number of capacity disks in the existing disk group
