1. Major clustering features are as follows(ESXi Host clusters):
DRS, DPM, HA, FT.
2. If you want to test SDRS, then please create datastore cluster. You can even test SIOC on individual datastores.
3. Other operations that can be even done without cluster: Snapshot, cloning, template, vMotion, Storage vMotion, alarms, add/remove host into vCenter or cluster, keeping host into maintenance mode, keeping datastore in maintenance mode (it requires DS cluster) etc.
Note: Above list is not exhaustive, there are several other small tasks can be performed. Make sure you have appropriate licenses.
Let me know if you need any help on any operation.
