Memory Reservations, Limits, and Shares
Memory Reservations are an ESX Server memory management technique used to control
how memory is allocated from an either an explicit or implicit resource pool by the
VMkernel to a virtual machine or group of virtual machines.
Reservations consist of two settings – a reservation, or guaranteed amount of physical
memory that will always be available to the virtual machine(s), and a limit, which is the
absolute maximum physical memory a virtual machine or group of virtual machines can
consume on the host
During peak operating hours, by definition more systems and more resources including
memory, will be being consumed. Therefore memory reservation is required. By setting a
reservation equal to the peak memory utilization, this will guarantee the application
receives all memory it requires.
