You are the VMware architect for Mason Public Library. This customer deployed a VMware environment several years ago, in the form of 3 stand-alone servers, each with 6 600GB internal SAS drives.

They do not have the additional budget for a new shared storage array. Which of the following is a recommended option to help them achieve higher availability?
A. Power off each virtual machine and copy them to a single server
B. Deploy vCenter Server and deploy the vSphere Storage Appliance
C. Use Storage vMotion to move all of the VMs to a single server
D. Configure CPU affinity to increase CPU access for each virtual machine
