My opinion is that support is generally very good. There are instances where they take longer to respond or resolve issues, especially when customers have urgent needs, but ultimately, resolution is achieved.

Punit Waghela

It would be nice to see technology supporting the Elastic Fabric Adapter on Amazon AWS, therefore getting RDMA technology for more low-latency connections.

Archiving data has reduced storage costs and provides reliable long‑term retention

We have not really come across any downsides for us. It is possible that the retrieval of data may be expensive, which could be an issue, but we have not experienced that in fairness. Integration with our policies would be beneficial. We have policies for our systems where we delete data after a certain number of years, and having integration with Amazon S3 Glacier would be good. Having a guarantee that Amazon S3 Glacier would persist for the amount of time that we require in our archives would be valuable. In other words, Amazon would need to commit to support for the period we need. We could be talking about 20 years or longer. We cannot always move to the next version because we need to maintain old systems and legacy systems in order to maintain archives. A guarantee around support would be a good thing to have.

Offers advanced features with notable emphasis on innovation

The best features of NetApp Cloud Volumes ONTAP include deduplication, compaction, and autonomous ransomware technology that native cloud storage solutions in AWS, Azure, or Google Cloud do not support. Moreover, NetApp Cloud Volumes ONTAP allows the use of multiple protocols including NFS, CIFS, and iSCSI, whereas native options may only support NFS and iSCSI. Customers already using on-premises NetApp storage such as FAS, AFF, or ASA can experience the same functionality on the cloud with NetApp Cloud Volumes ONTAP, which adds significant value. For data protection, customers can take advantage of the Snapshot technology available with NetApp Cloud Volumes ONTAP. This technology facilitates data recovery by allowing snapshots to be stored either on the same storage or on a disaster recovery (DR) storage. NetApp Cloud Volumes ONTAP helps us to take snapshots and store them on the same storage, with options for migration or replication of those snapshots to different storage, including on-premises DR storage or other cloud storage, providing excellent disaster recovery capabilities.
