Separate capacity from performance.
Logical data is the information you need to keep. Provisioned capacity also allows for protection overhead, snapshots, growth and free space. A single capacity figure cannot describe latency, IOPS or sustained throughput.
| Model | Typical fit | Question to ask |
|---|---|---|
| Block | Databases and virtual disks | What latency and IOPS does the application require? |
| File | Shared directories and collaborative workloads | How many files, clients and metadata operations? |
| Object | Archives, media and large datasets | Which API, access and retention requirements apply? |
