Advanced Storage >
Use View Storage
Accelerator
If you select or deselect Use View Storage Accelerator, or reschedule when the View Storage
Accelerator digest les are regenerated, the seings do aect existing virtual machines. If you
modify View Storage Accelerator seings for an existing desktop pool, the changes do not take
eect until the virtual machines in the desktop pool are powered o. See "Congure View
Storage Accelerator for View Composer Linked Clones" in the Seing Up Desktop and Application
Pools in View document.
N If you select Use View Storage Accelerator on an existing linked-clone desktop pool, and
the replica was not previously enabled for View Storage Accelerator, this feature might not take
eect right away. View Storage Accelerator cannot be enabled while the replica is in use. You can
force View Storage Accelerator to be enabled by recomposing the desktop pool to a new parent
virtual machine.
This option is automatically enabled on instant clones.
Advanced Storage >
Reclaim VM disk
space
If you select or deselect Reclaim VM disk space, or reschedule when the virtual machine disk
space reclamation occurs, the new seings do aect existing virtual machines if they were
created with space-ecient disks. See "Reclaim Disk Space on Linked-Clone Virtual Machines" in
the Seing Up Desktop and Application Pools in View document.
This option does not apply to instant clones.
Advanced Storage >
Use native NFS
snapshots (VAAI)
If you select or deselect Use native NFS snapshots (VAAI), the new seing only aects virtual
machines that are created after the seings are changed. You can change existing virtual
machines to become native NFS snapshot clones by recomposing and, if needed, rebalancing the
desktop pool. See "Using View Composer Array Integration with Native NFS Snapshot
Technology" in the Seing Up Desktop and Application Pools in View document.
This option is not supported for instant clones.
Advanced Storage >
Transparent Page
Sharing Scope
If you change the Transparent Page Sharing Scope seing, the new seing takes eect the next
time the virtual machine is powered on.
Select the level at which to allow transparent page sharing (TPS). The choices are Virtual
Machine (the default), Pool, Pod, or Global. If you turn on TPS for all the machines in the pool,
pod, or globally, the ESXi host eliminates redundant copies of memory pages that result if the
machines use the same guest operating system or applications.
Page sharing happens on the ESXi host. For example, if you enable TPS at the pool level but the
pool is spread across multiple ESXi hosts, only virtual machines on the same host and within the
same pool will share pages. At the global level, all machines managed by View on the same ESXi
host can share memory pages, regardless of which pool the machines reside in.
N The default seing is not to share memory pages among machines because TPS can pose
a security risk. Research indicates that TPS could possibly be abused to gain unauthorized access
to data in very limited conguration scenarios.
This option is automatically enabled on instant clones.
If you edit a instant-clone desktop pool to add or remove datastores, rebalancing of the VMs happens
automatically when a new clone must be created, for example, when a user logs o or when you increase
the size of the pool. If you want rebalancing to happen faster, take the following actions:
n
If you remove a datastore, manually remove the desktops on that datastore so that the new desktops
will be created on the remaining datastores.
n
If you add a datastore, manually remove some desktops from the original datastores so that the new
desktops will be created on the new datastore. You can also remove all desktops so that when they are
recreated, they will be evenly distributed across the datastores.
