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?
A. Change the Default Storage Policy to have stripe width of 13.
B. Modify the stripe width for the application on the advanced settings for the VM.
C. Add more magnetic capacity devices in the affected host.
D. Increase the stripe width based on the number of capacity devices within the disk group.
D
“”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.””
