Setting Up Desktop and Application Pools in View

Table 5‑1. Worksheet: Configuration Options for Creating a Linked-Clone Desktop Pool (Continued)
Option Description Fill In Your Value Here
Initiate reclamation when
unused space on VM
exceeds:
(Available only if you do not use Virtual SAN or
Virtual Volumes) Type the minimum amount of
unused disk space, in gigabytes, that must accumulate
on a linked-clone OS disk to trigger space reclamation.
When the unused disk space exceeds this threshold,
View initiates the operation that directs the ESXi host
to reclaim space on the OS disk.
This value is measured per virtual machine. The
unused disk space must exceed the specified threshold
on an individual virtual machine before View starts the
space reclamation process on that machine.
For example: 2 GB.
The default value is 1 GB.
Blackout Times Configure days and times during which View Storage
Accelerator regeneration and the reclamation of virtual
machine disk space do not take place.
To ensure that ESXi resources are dedicated to
foreground tasks when necessary, you can prevent the
ESXi hosts from performing these operations during
specified periods of time on specified days.
For details, see “Set Blackout Times for ESXi
Operations on View Virtual Machines,” on page 216.
Transparent Page Sharing
Scope
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.
NOTE The default setting 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 configuration scenarios.
Domain Select the Active Directory domain and user name.
View Composer requires certain user privileges to
create a linked-clone pool. The domain and user
account are used by QuickPrep or Sysprep to
customize the linked-clone machines.
You specify this user when you configure View
Composer settings for vCenter Server. You can specify
multiple domains and users when you configure View
Composer settings. When you use the Add Desktop
Pool wizard to create a pool, you must select one
domain and user from the list.
For information about configuring View Composer,
see the View Administration document.
