14 Dell EMC SC Series and VMware vSphere Virtual Volumes Best Practices | 3161-BP-SC
After the VASA Provider is registered and a storage container is created, vSphere hosts will recognize the
protocol endpoints created and presented by DSM as protocol endpoints rather than just 512 Byte devices.
Protocol endpoints are visible in the vSphere Web Client after the storage container is created
and presented to the hosts
The storage container becomes the pool of storage where various Virtual Volumes are created. Most notably
these will be Config vVols, and Data vVols. A Swap vVol is created when the corresponding virtual machine is
powered on.

Note: Storage Containers or vVol datastores may be used as heartbeat datastores for vSphere clusters
configured with High Availability (HA) enabled.
4.2 Changing the Protocol Endpoint Path Selection Policy
With Virtual Volumes enabled, I/O generated by virtual machines is multiplexed through protocol endpoints.
Protocol endpoints are claimed by the VMW_SATP_ALUA Storage Array Type Plugin (SATP) which uses a
default Path Selection Policy (PSP) of Most Recently Used (MRU). Dell recommends using the Round Robin
or Fixed PSP for SC Series devices. This can be performed with the vSphere Web Client, esxcli, or VMware
vSphere
