• Protocol Endpoint:
- The Protocol Endpoint is a unique volume on the SAN, it has a size of zero megabytes and a LUN ID of 256.
- It is the SAN endpoint of the communication between the ESXi™ host and the Virtual Volumes on the SAN.
The transport protocol (iSCSI in the case of PS Series) endpoint is where the communication is turned over
to internal SAN protocols. This unique volume can be thought of as a multiplexer LUN that acts as both
the target and the initiator, and enables ESXi hosts to see a single volume while multiple independent
volumes fan out behind it in the SAN. These multiple independent volumes are included in a virtual
machine.
- The protocol endpoint is also where access controls are placed and initiators are queried to insure that
they are permitted access to the storage container and virtual volumes. VSM manages these access
controls directly from vCenter.
