Specify an Unreplicated Datastore for Swap Files

Every virtual machine requires a swap file. By default,
vCenter Server
 creates swap files in the same datastore as the other virtual machine files. To prevent
Site Recovery Manager
 from replicating swap files, you can configure virtual machines to create them in an unreplicated datastore.
Under normal circumstances, you should keep the swap files in the same datastore as other virtual machine files. However, you might need to prevent replication of swap files to avoid excessive consumption of network bandwidth. Some storage vendors recommend that you do not replicate swap files. Only prevent replication of swap files if it is absolutely necessary.
If you are using an unreplicated datastore for swap files, you must create an unreplicated datastore for all protected hosts and clusters at both the protected and recovery sites. All hosts in a cluster must have access to the unreplicated datastore, otherwise vMotion does not work.
  1. In the
    vSphere Client
    , select
    Hosts and Clusters
    , select a host, and click
    Configure
    .
  2. Under
    Virtual Machines
    , select
    Swap file location
    , and click
    Edit
    .
  3. Select
    Use a specific datastore
    , and select an unreplicated datastore.
  4. Click
    OK
    .
  5. Power off and power on all virtual machines on the host.
    Resetting the guest operating system is not sufficient. The change of swapfile location takes effect after you power off then power on the virtual machines.
  6. Browse the datastore that you selected for swapfiles and verify that VSWP files are present for the virtual machines.
