As you can see, the process for creating a VM is pretty straightforward. What's not so
straightforward, though, are some of the values that should be used when creating new VMs.
What are the best values to use?
Choosing Values for Your New Virtual Machine
Choosing the right values to use for the number of virtual CPUs, the amount of memory, or
the number or types of virtual NICs when creating your new VM can be difi cult. Fortunately,
there's lots of documentation out there on CPU and RAM sizing as well as networking for VMs,
so our only recommendation there will be to right-size the VMs based on your needs (see the
sidebar “Provisioning Virtual Machines Is Not the Same as Provisioning Physical Machines”
later in this chapter).
Virtual Machine Sizing Can Have an Impact
Determining the right size for your VMs is a crucial part of your overall vSphere design, and it
can impact a number of diff erent areas. For more information on how right-sizing VMs impacts
other areas of your vSphere design, refer to
VMware
vSphere
Design
by Forbes Guthrie and Scott
Lowe (Sybex, 2013).
For other areas besides these, the guidance isn't quite so clear. Out of all the options available
during the creation of a new VM, four areas tend to consistently generate questions from both
new and experienced users alike:
How can I i nd out how to size my VMs?
◆
How should I handle naming my VMs?
