Users are complaining that they cannot access their files located on a file server virtual machine. The vSphere client shows a triggered alarm stating disk latency is beyond the default threshold for the datastore where the user file server is located. The Path Selection Policy has been set by the ESX Host to Fixed with default path settings.
Which of the following two options could be used to increase performance of the file server VM (Choose Two)?
A.
Change the Path Selection Policy to Round Robin
B.
Change the Path Selection Policy to Most Recently Used (MRU)
C.
Use disk shares to increase the priority for the datastore housing the file server VM
D.
Use Storage VMotion to move the file server VM to a datastore with lower latency
Switching to Round Robin from MRU or Fixed is safe and supported for all arrays, Please check with your vendor for supported Multipathing policies for your storage array. Switching to a unsupported pathing policy can cause an outage.
Warning: VMware does not recommend changing the LUN policy from Fixed to MRU, as the automatic selection of the pathing policy is based on the array that has been detected by the NMP PSP.
Also using disk shares could help if latency is caused by the VMs on this same host, of course other VMs would suffer, but the file server would work better.
Another stupid question.
