Portworx VMware shared architecture
The following diagram gives an overview of the Portworx architecture on vSphere using shared datastores.
- Portworx runs on each Kubernetes minion/worker.
- Based on the given spec by the end user, Portworx on each node will create its disk on the configured shared datastores or datastore clusters.
- Portworx will aggregate all of the disks and form a single storage cluster. End users can carve PVCs (Persistent Volume Claims), PVs (Persistent Volumes) and Snapshots from this storage cluster.
- Portworx tracks and manages the disks that it creates. In a failure event, if a new VM spins up, Portworx on the new VM will be able to attach to the same disk that was previously created by the node on the failed VM.
