Keeping Linked-Clone Desktops Provisioned and Ready During View Composer
Operations
If your users must be able to access View desktops at all times, you must maintain a certain number of desktops
that stay provisioned and ready to accept connection requests from your users even when View Composer
maintenance operations take place. You can set a minimum number of provisioned, ready desktops while View
Composer refreshes, recomposes, or rebalances the linked-clone virtual machines in a pool.
When you specify a Minimum number of ready (provisioned) desktops during View Composer
maintenance operations, View Manager ensures that the specified number of desktops stays provisioned and
ready while View Composer proceeds through the operation. You can specify the minimum number of ready
desktops when you create or edit a linked-clone pool.
The following guidelines apply to this setting:
n
If you use a naming pattern to provision desktops and provision desktops on demand, set the number of
ready desktops during View Composer operations to a smaller value than the specified Min number of
desktops. If the minimum number were smaller, your pool could end up with fewer total desktops than
the minimum number you want to keep provisioned and ready during View Composer operations. In
this case, View Composer maintenance operations could not take place.
n
If you provision desktops by manually specifying a list of desktop names, do not reduce the total pool
size (by removing desktop names) to a lower number than the minimum number of ready desktops. In
this case, View Composer maintenance operations could not take place.
n
If you set a large minimum number of ready desktops in relation to the pool size, View Composer
maintenance operations might take longer to complete. While View Manager maintains the minimum
number of ready desktops during a maintenance operation, the operation might not reach the concurrency
limit that is specified in the Max concurrent View Composer maintenance operations setting.
For example, if a pool contains 20 desktops and the minimum number of ready desktops is 15, View
Composer can operate on at most five desktops at a time. If the concurrency limit for View Composer
maintenance operations is 12, the concurrency limit is never reached.
n
The term "ready" applies to the state of the linked-clone virtual machine, not the desktop status that is
displayed in View Administrator. A virtual machine is ready when it is provisioned and ready to be
powered on. The desktop status reflects the View-managed condition of the desktop. For example, a
desktop can have a status of Connected, Disconnected, Agent Unreachable, Deleting, and so on.
Use Existing Active Directory Computer Accounts for Linked Clones
When you create or edit a desktop pool, you can configure View Composer to use existing computer accounts
in Active Directory for newly provisioned linked clones.
By default, View Composer generates a new Active Directory computer account for each linked clone that it
provisions. The Allow reuse of pre-existing computer accounts option lets you control the computer accounts
that are created in Active Directory by ensuring that View Composer uses existing AD computer accounts.
