If you are doing an on-prem deployment, the following cloud providers offer all 3 types of required storage (File storage, Block storage, S3 bucket/Object storage):
- Red Hat OpenShift Container Storage
- Ceph
- Portworx
If you are using a public cloud, each cloud provider has options for File storage, Block storage, and S3 bucket (Object storage).
Note:
- If you do not use Monitoring, you don't need an S3 bucket (Object storage).
- When you work with IBM Support on your deployment sizing, IBM can provide storage I/O requirements.
