The correct answer is B. Increase the stripe width based on the number of capacity devices within the disk group. In a Hybrid vSAN OSA setup, data resides on magnetic disks while caching occurs on SSDs. For I/O-intensive applications, increasing the stripe width spreads data across more capacity devices within a disk group, improving parallelism and read/write performance from the slower…
Question
A vSAN administrator has been tasked with troubleshooting an application in a Hybrid vSAN OSA environment. The application is I/O intensive, and the magnetic capacity devices may be playing a role in slow performance, so the administrator decides to take action to help resolve the problem. Which action should the administrator take?
Options
- AAdd more magnetic capacity devices in the affected host
- BIncrease the stripe width based on the number of capacity devices within the disk group
- CModify the stripe width for the application on the advanced settings for the VM
- DChange the Default Storage Policy to have stripe width of 14

Explanation
In a Hybrid vSAN OSA setup, data resides on magnetic disks while caching occurs on SSDs. For I/O-intensive applications, increasing the stripe width spreads data across more capacity devices within a disk group, improving parallelism and read/write performance from the slower magnetic disks without adding new hardware.
