Sizing Guidelines for Linked-Clone Pools
When you create or edit a linked-clone desktop pool, the Select Linked Clone Datastores page displays a
table that provides storage-sizing guidelines. The table can help you to decide which datastores to select for
the linked-clone disks. The guidelines calculate space needed for new linked clones.
Sizing Table for Linked-Clone Disks
Table 15-1 shows an example of storage-sizing recommendations that might be displayed for a pool of 10
virtual machines if the parent virtual machine has 1GB of memory and a 10GB replica. In this example,
different datastores are selected for OS disks and View Composer persistent disks.
Table 15‑1. Example Sizing Table for Linked-Clone Disks
Data Type
Selected Free
Space (GB)
Min Recommended
(GB) 50% Utilization (GB)
Max Recommended
(GB)
OS disks 184.23 40.00 80.00 130.00
Persistent disks 28.56 4.00 10.00 20.00
The Selected Free Space column shows the total available space on all of the datastores that you selected for
a disk type such as OS disks.
The Min Recommended column shows the minimum amount of recommended storage for a pool.
The 50% Utilization column shows the recommended storage when the linked-clone disks grow to 50% of
the parent virtual machine.
The Max Recommended column shows the recommended storage when the linked-clone disks approach
the full size of the parent virtual machine.
If you store OS disks and persistent disks on the same datastore, View calculates the storage requirements of
both disk types. The Data Type is shown as Linked clones instead of a particular disk type.
If you store View Composer replicas on a separate datastore, the table also shows storage recommendations
for the replicas and adjusts the recommendations for OS disks.
Sizing Guidelines
The table provides general guidelines. Your storage calculations must account for additional factors that can
affect actual storage growth in the linked-clone pool.
For OS disks, your sizing estimates depend on how frequently you refresh and recompose the pool.
If you refresh your linked-clone pool between once a day and once a week, make sure that the Selected Free
Space can accommodate storage use between the Min Recommended and 50% Utilization estimates.
If you rarely refresh or recompose the pool, the linked-clone disks continue to grow. Make sure that the
Selected Free Space can accommodate storage use between the 50 % Utilization and Max Recommended
estimates.
For persistent disks, your sizing estimates depend on the amount of Windows profile data that users
generate on their desktops. Refresh and recompose operations do not affect persistent disks.
Sizing Guidelines When You Edit an Existing Desktop Pool
View estimates the storage space that is needed for new linked clones. When you create a desktop pool, the
sizing guidelines encompass the entire pool. When you edit an existing desktop pool, the guidelines
encompass only the new linked clones that you add to the pool.
For example, if you add 100 linked clones to a desktop pool and select a new datastore, View estimates
space requirements for the 100 new clones.
