QuestionQ80

Performance-tuning, Optimization, and Upgrades

A vSAN administrator is assigned to troubleshoot an application in a Hybrid vSAN OSA environment. The application is I/O-intensive, and the magnetic capacity devices might be contributing to slow performance, so the administrator decides to take action to help resolve the issue.

Which action should the administrator take?

  • A Add more magnetic capacity devices in the affected host
  • B Increase the stripe width based on the number of capacity devices within the disk group
  • C Modify the stripe width for the application on the advanced settings for the VM
  • D Change the Default Storage Policy to have stripe width of 14
Explanation

In a hybrid vSAN OSA cluster, increasing the Number of Disk Stripes Per Object in the applicable storage policy spreads an I/O-intensive workload across more magnetic capacity devices. This can increase I/O parallelism when those capacity devices are the source of contention. The stripe-width value must be feasible for the available capacity devices and is limited to 1–12.
