Question
An All-Flash vSAN cluster has 4-nodes with this disk group composition on each host:
- 1 x 800 GB SAS SSD
- 6 x 3.84 TB SATA SSD
An administrator observes that in an All-Flash cluster, the Write Buffer Free Percentage is consistently low. As a result there is increased latency experienced by the workloads. Which remediation steps will resolve this issue?
Options
- AAdd a second disk group with a new cache device and distribute the capacity disks equally.
- BAdd a second cache device to the same disk group to increase the caching size.
- CReplace the existing cache device with a larger cache device.
- DModify advanced vSAN configuration parameters to utilize the complete 800 GB for caching.
