An administrator has determined that storage performance to a group of virtual machines is
reduced during peak activity. The virtual machines are located in a VMFS datastore called
Production1 on an active-active storage array. The ESXi 5.x host running the virtual machines is
configured with an MRU multipathing policy.
Which two actions can be taken to improve the storage performance of these virtual machines?
(Choose two.)
A.
Add virtual storage, create a VMFS datastore called Production2 on the new storage, and then
migrate some of the virtual machines from Production1 to Production2.
B.
Change the storage multipathing policy to Round Robin.
C.
Add physical storage, create a VMFS datastore called Production2 on the new storage, and
then migrate some of the virtual machines from Production1 to Production2.
D.
Change the storage multipathing policy to Fixed with default settings.
Explanation:
Round Robin (VMware) The host uses an automatic path selection algorithm rotating through all
available paths. This implements load balancing across all the available physical paths.
Load balancing is the process of spreading server I/O requests across all available host paths.
The goal is to optimize performance in terms of throughput (I/O per second, megabytes per
second, or response times).
