5V0-22.21 Question #5: Real Exam Question with Answer & Explanation

The correct answer is D. Increase the stripe width based on the number of capacity devices within the disk group.. NumberOfDiskStripesPerObject, commonly referred to as stripe width, is the setting that defines the minimum number of capacity devices across which each replica of a storage object is distributed. Virtual SAN may actually create more stripes than the number specified in the polic

Question

A vSAN administrator has been tasked with troubleshooting an application in a Hybrid vSAN 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

  • AChange the Default Storage Policy to have stripe width of 13.
  • BModify the stripe width for the application on the advanced settings for the VM.
  • CAdd more magnetic capacity devices in the affected host.
  • DIncrease the stripe width based on the number of capacity devices within the disk group.

Explanation

NumberOfDiskStripesPerObject, commonly referred to as stripe width, is the setting that defines the minimum number of capacity devices across which each replica of a storage object is distributed. Virtual SAN may actually create more stripes than the number specified in the policy. Striping may help performance if certain virtual machines are I/O intensive and others are not. With striping, a virtual machines data is spread across more drives which all contribute to the overall storage performance experienced by that virtual machine. In the case of hybrid, this striping would be across magnetic disks. In the case of all-flash, the striping would be across whatever flash devices are making up the capacity layer.
