n
Verify that the virtual hardware version is 14 or higher.
n
Verify that you have the Datastore.Allocate space privilege on the virtual machine.
n
Verify that the host or the cluster on which the virtual machine resides has available PMem resources.
Procedure
1 Right-click a virtual machine in the inventory and select Edit Settings.
2 On the Virtual Hardware tab, add a new NVDIMM device. click Add a new device and select
NVDIMM from the drop-down menu.
Client Steps
vSphere Client Click the Add New Device button and select NVDIMM from the drop-down menu.
vSphere Web Client a Select NVDIMM from the New device drop-down menu at the bottom of the
wizard.
b Click Add.
The NVDIMM device appears in the Virtual Hardware devices list together with the virtual NVDIMM
controller. Each virtual machine can have a maximum of one virtual NVDIMM controller and each
NVDIMM controller can have up to 64 virtual NVDIMM devices.
Note You can change the size of the NVDIMM device at a later time. The virtual machine must be
powered off.
3 In the New NVDIMM text box, enter the size of the NVDIMM device and select the units from the
drop-down menu.
Note If the virtual machine uses PMem storage, the hard disks that are stored on a PMem datastore
and the NVDIMM devices that you add to the virtual machine all share the same PMem resources.
So, you must adjust the size of the newly added devices in accordance with the amount of the PMem
available to the host. If any part of the configuration requires attention, the wizard alerts you.
Virtual Disk Configuration
You can add large-capacity virtual disks to virtual machines and add more space to existing disks, even
when the virtual machine is running. You can set most of the virtual disk parameters during virtual
machine creation or after you install the guest operating system.
You can store virtual machine data in a new virtual disk, an existing virtual disk, or a mapped SAN LUN. A
virtual disk appears as a single hard disk to the guest operating system. The virtual disk is composed of
one or more files on the host file system. You can copy or move virtual disks on the same hosts or
between hosts.
For virtual machines running on an ESXi host, you can store virtual machine data directly on a SAN LUN
instead of using a virtual disk file. This option is useful if in your virtual machines you run applications that
must detect the physical characteristics of the storage device. Mapping a SAN LUN also allows you to
use existing SAN commands to manage storage for the disk.
