Nimble CS3000 capacity/deduplication issue

TSAdvisor — Fri, 25 Aug 2023 03:33:14 GMT

We've been receiving the following error message. We are considering expanding capacity on this storage array. Would expanding likely resolve the issue below?

"Array NimbleVeeam in pool default is approaching the maximum limits on its internal resources required for efficient data deduplication. On reaching these limits, the system will skip deduplication efforts. The array will still continue to serve I/O. To take preventive measures, refer to documentation and/or InfoSight wellness report."

197.8 TiB of 215.3 TiB

Hi TSAdvisor,

Yes, the issue will be resolved by expanding physical capacity.

Please follow the below steps to expand the storage capacity.

1. Analyze your current storage usage and performance requirements.
2. You can free up some capacity by deleting unused VMs, and VVs and deleting duplicate data if any.
3. If you still facing storage capacity issues after deleting unused VMs, VVs, and duplicate data, you will need to expand the storage capacity by adding new disks.
4. Make sure your new disks meet your capacity and performance requirements.
6. Utilize your storage array's automated data redistribution feature to balance data across all disks, ensuring optimal performance and utilization.
7. After data migration, thoroughly test the functionality and performance of the virtual machines and applications.
8. You should consider implementing a long-term capacity planning strategy as your storage needs continue to grow.

Note: Ensure you have a reliable backup of all your data before making any changes.

Hope this helps.

Regards,
Satish

@Satish04 Satish, are you sure that expanding the capacity will resolve the issue? The CS3000 has a Maximum Deduplication Capacity of 40 TiB. Perhaps this is the maximum limits referred to in the error message. In this case, a controller upgrade will be necessary to resolve the issue.
