Mapping volumes to an ESXi server
28 Dell EMC SC Series: Best Practices with VMware vSphere | 2060-M-BP-V
Configuration of VLANs within the Dell Storage Manager (Enterprise Manager) client
Note: For added flexibility, Jumbo frames can be enabled on a per-fault-domain basis.
6.8 Configuring the FCoE software initiator for multipathing
When using the ESXi software FCoE, volumes are assigned to the VMW_SATP_LOCAL by default. In some
instances, this default policy will cause paths to go unclaimed. To remedy this situation, it may be necessary
to adjust the claim rules on each ESXi host so that FCoE volumes are correctly assigned to the
VMW_SATP_ALUA.

6.9 VMware multipathing policies
When configuring the path-selection policy of each datastore or volume, administrators have the choice of
round robin, fixed, or most recently used. The default path selection policy for the SC Series system depends
on the SCOS version and the associated SATP module detected. Round robin is highly recommended for
ease of management if there are no technical reasons against using it (such as with Microsoft failover
clusters).
