How does vSphere High Availability calculate the memory slot size of a virtual machine?
A. Virtual machine memory reservation + overhead of largest virtual machine
B. Virtual machine memory reservation – overhead of largest virtual machine
C. Virtual machine memory reservation + overhead of smallest virtual machine
D. Virtual machine memory reservation – overhead of smallest virtual machine
Slot size is comprised of two components, CPU and memory.
vSphere HA calculates the CPU component by obtaining the CPU reservation of each powered-on virtual machine and selecting the largest value. If you have not specified a CPU reservation for a virtual machine, it is assigned a default value of 32MHz. You can change this value by using the das.vmcpuminmhz advanced option.)
vSphere HA calculates the memory component by obtaining the memory reservation, plus memory overhead, of each powered-on virtual machine and selecting the largest value. There is no default value for the memory reservation.
