How to Access the Advanced Panel
The storage policy change is done from the CloudPe Advanced Panel
⚠️ Important
The storage policy change option is available in the Advanced Panel, not the standard CMP dashboard.
You must navigate to the Advanced Panel for your region to access this feature.
1
Log in to CloudPe CMP Dashboard
Go to
cmp.dashboard.controlcloud.app and sign in with your credentials.
2
Select your Region
Click the region selector in the top navigation bar. Select your region (e.g.,
IN-WEST2) from the dropdown list.
3
Open the Advanced Panel
After selecting your region, click the external link icon (↗) that appears next to the region name. This opens the Advanced Panel in a new tab at
in-west2.controlcloud.app:8800.
3
Upgrade: Standard NVMe → Pro NVMe
Double your IOPS and throughput with a live, zero-downtime upgrade
✅ Zero downtime. The volume stays attached and fully operational during the policy change.
Your VM continues running without interruption.
1
Navigate to Volumes in the Advanced Panel
In the left sidebar, click Volumes under the Compute section. You will see a list of all your volumes with their current Policy column showing the active storage tier.
2
Click on the volume to open its detail panel
Click the volume name you want to upgrade. A slide-out panel opens on the right. Scroll down to the Properties section. You will see Storage policy: Standard NVMe with a pencil (✏) edit icon.
3
Click the pencil icon to edit the Storage Policy
Click the ✏ (pencil) icon next to Storage policy. The field becomes an inline dropdown showing the current value Standard NVMe, along with ✓ (save) and ✕ (cancel) buttons.
4
Select Pro NVMe from the dropdown
Click the dropdown to expand it. You will see both available options: Pro NVMe and Standard NVMe. Select Pro NVMe.
5
Confirm the selection and save
After selecting Pro NVMe, the dropdown updates to show your selection. Click the ✓ (checkmark) button to apply the change.
6
Verify the upgrade is applied
The Properties section now shows Storage policy: Pro NVMe. The Last modified timestamp will also update, confirming the change was applied successfully. The volume is now running on Pro NVMe — 50,000 IOPS and 2,000 MB/s.
4
Downgrade: Pro NVMe → Standard NVMe
Reduce costs by switching back to Standard NVMe — still zero downtime
⚠️ Performance will reduce from 50,000 to 25,000 IOPS and from 2,000 to 1,000 MB/s after downgrade.
No downtime or data loss — the volume stays attached throughout.
1
Navigate to the volume in the Advanced Panel
In the Advanced Panel, go to Volumes in the sidebar and click the volume currently on Pro NVMe. In the Properties section, confirm Storage policy: Pro NVMe is shown. Click the ✏ pencil icon next to it.
2
Click the pencil to open the editor
After clicking the pencil icon, the Storage policy row switches to inline edit mode showing Pro NVMe in a dropdown with ✓ and ✕ buttons.
3
Select Standard NVMe from the dropdown
Click the dropdown to expand it. Both options are shown — Pro NVMe (currently selected) and Standard NVMe. Click Standard NVMe to select it.
4
Confirm and save the downgrade
The dropdown updates to show Standard NVMe. Click the ✓ (checkmark) button to apply the downgrade. The Properties section will update to confirm Storage policy: Standard NVMe with a new Last modified timestamp.

Frequently Asked Questions
Common questions about NVMe storage tier changes
Will my VM experience any downtime during the tier change?
+
No. The tier change between Standard NVMe and Pro NVMe is performed live on the storage backend.
Your VM remains running and the volume stays attached throughout the process. Typical changes complete within seconds.
Why can’t I change from Eco NVMe to Standard or Pro live?
+
Eco NVMe uses Erasure Coding, while Standard and Pro NVMe use 3× Replication.
These are fundamentally different storage architectures, so an in-place migration is not possible.
To switch from Eco to Standard/Pro, you must create a new volume, copy your data, and swap the attachment.
How long does the policy change take to apply?
+
The policy change is applied almost instantly — typically in a few seconds. Once you click the ✓ button,
the Properties section updates immediately and the Volumes list reflects the new tier.
There is no background migration or wait time.
Will my billing change immediately after the tier change?
+
Yes. Billing is calculated per hour based on your current storage tier. Once the policy change is saved,
the new rate applies from that moment forward. If you upgrade to Pro NVMe, you will be billed at ₹8.00/GB/month
from that point. If you downgrade back to Standard, billing reverts to ₹6.20/GB/month.
Why is the Change Policy option not visible in the main CMP dashboard?
+
The storage policy change is only available in the Advanced Panel (accessed via the region selector
→ external link icon). The main CMP dashboard does not expose this option in the current UI version.
Always use the Advanced Panel at
in-west2.controlcloud.app:8800 (or your region’s equivalent) for
policy changes.
Can I change the policy while the volume is attached to a running VM?
+
Yes — that is the recommended approach. The volume can be In Use (attached to a running VM) during the tier change.
You do not need to detach, stop, or snapshot the volume before changing the policy.
