Using Reclaim to Free Up Resources
Use the
Reclaim
feature in
vRealize
Operations Manager
to identify
underutilized workloads and reclaim resources from across your environment. Where You Find
Reclaim
Select
Reclaim
under
Optimize
in
the left pane. From the Launchpad, select the Capacity
card
under Pillars of Operations and click View
in the Reclaim
card. Double-click on a
data center graphic to display the object details screen for the data center.
How Reclaim
Works
The Capacity Optimization and Reclaim features are
tightly integrated functions that allows you to assess workload status and resource
contention in data centers across your environment. You can determine time remaining
until CPU, memory, or storage resources run out, and realize cost savings when
underutilized VMs can be reclaimed and deployed where needed.
When you open the
Reclaim
page,
graphical representations of all the data centers and custom data centers in
your environment appear. By default, they are shown in order of time remaining,
beginning from the upper left, where the most constrained data centers appear.
To review the status of a data center, click the graphic. The area following
refreshes to display details about the selected data center. The
How much you
can potentially save
pane reflects potential capacity savings and
indicates a possible cost savings once you have reclaimed underused or powered
off VMs. The
Total
Reclaimable Capacity
pane gives details of the reclaimable
percentages for CPU, memory, and disk space.
The table at the bottom of the page provides important
information about the VMs that offer the most cost savings. The VMs are listed by
Powered Off
VMs
, Idle
VMs
, Snapshots
, and Orphaned Disks
. The
highest priority heading is at the far left. You can specify what information is
included in your reclaim action. For example, when you click a column heading, the
table lists, by data center and then by VM, the allocated and reclaimable CPUs and
memory, respectively. Then, for example, you can select the box next to one or more
VM names and click the EXCLUDE VM(S)
button to keep those VMs from being included in any
reclaim action. You can also select VMs to resize. Reclamation
Settings
Select the gear icon next to the page heading to
customize Reclamation Settings. This affects all data centers. Using the Reclamation
Settings, you can exclude, for example all snapshots from being included in the
reclaim action - by deselecting the Snapshots check box. Similarly, you can include
or exclude powered-off VMs, idle VMs, and orphaned disks. For more information, see
Reclamation Settings.
To provide read-only access
to the Reclamation Settings page for a user, configure the user role in the
Access Control page (Roles tab) under
. Select the Manage Global Settings
permissions under in the Permissions
pane to grant access to
modify the Reclamation Settings page. Unselect the Manage Global
Settings
permissions to grant read-only access. Run a Reclaim
Action
Run a reclaim action as
follows:
- In the table headings,Selectthe types of VMs to reclaim.
- Clickthe name of a listed cluster to show its VM list.
- Selecteach VM or snapshot you want to reclaim.
- ClickDelete VM(s)to reclaim their resources.

the total calculated potential cost savings when you accept system reclamation
recommendations.

Total Reclaimable Capacity
| Lists potential cost

Reclaimable Capacity:
how much capacity is available to reclaim from idle resources
% Reclaimable:
percentage of total CPU, memory, or storage you can reclaim.

Duration older than:

idle or powered off for at least the selected time period: one week, two weeks,
or a month.

Table of Potential Cost Savings
| Tabular representation of the VMs, Idle VMs,
Snapshots, and Orphaned disks in the selected data center
from which resources can be reclaimed. Click one of the
elements - powered off VMs, idle VMs, and so on - to refresh the table with
data for that element. The table lists the relevant clusters. To see the VMs
hosted in a given cluster, click the chevron to the left of the cluster name.
Click the check box
next to the VMs you want to act on, or click the check box next to the column
heading VM Name to act on all the VMs.
Once you select a VM
or VMs, the dimmed options above the table become visible, as follows.
Exclude
VM(s) : The selected VMs are excluded from
your subsequent action. Excluding VMs from a reclamation
action can reduce the potential cost savings. For powered Off VMs:
For idle VMs:
For Snapshots:
SHOW|HIDE EXCLUDED VMS : Toggle displays or
hides the list of VMs you previously excluded. By default,
calculations for reclaimable resources are based on the demand model. But if
you turn on the allocation model in the policy settings, the calculations are
based on the allocation model.
For Orphaned Disks:
SHOW|HIDE EXCLUDED DISKS : Toggle displays
or hides the list of disks you previously excluded. Excluded
disks are not listed in the exported CSV file. |
