Configuring a Swap File
Use the Swap Configuration option to create and configure a swap file, which
enables your virtual machines to use more memory than is physically available on the
server. For background, see Memory Resource Management on page 363.
You can manage a single swap file with the management interface. ESX Server can
manage up to 8 swap files, but you must use vmkfstools to do so. For information
on vmkfstools, see Using vmkfstools on page 259.
To change your swap file settings, click Edit.
You can change the following settings:
• The volume on which to locate the swap file.
Caution: Do not place your swap file on a SAN disk. If the SAN cable is removed,
ESX Server becomes unstable.
