6 Data Migration from Dell PS Series or PowerVault MD3 to Dell EMC SC Series Storage using Thin Import | 3041-BP-EM
Note: Any discrepancies in MTU size will cause the Thin Import process to fail. It is recommended to set the
MTU size to 1500 bytes on the SC Series array.
For detailed information on setting the MTU size, see the following documents:
SC Series: Dell Storage Manager Administrator’s Guide, available on the Knowledge Center at the SC Series
customer portal (login required)
PS Series: Dell EqualLogic Group Administrator’s Guide, available on the PS Series support site (login
required).
MD3xxxi series: Documentation for the various MD3 series iSCSI arrays can be found on the Dell Product
support site.
2.2 SC Series storage requirements
Note: Using the Thin Import process to import from PS Series Windows volumes requires SCOS 6.7 or
higher. SCOS 7.0 or higher is required to import data from PS Series VMware volumes. SCOS 7.2.10 or
higher is required to import data from PowerVault MD3 series volumes.
2.2.1 Fault domains
Front-end ports are categorized into fault domains that identify allowed port movement when a controller or
port fails. Fault domains enable the controller to use all designated ports as needed for efficiency and
redundancy. All ports are primary and can read and write I/O. If a port fails, any port within the fault domain
takes over for the failed port.
Note: Standard fault domains are required when using Thin Import. Virtual fault domains (available on some
SC Series arrays) are not supported for Thin Import.
A minimum of one iSCSI fault domain on the SC Series array is required to use the Thin Import process to
import data from a PS Series or an iSCSI-connected MD3 Series array. It is highly recommended that the PS
Series or MD3 Series array be on the same subnet as the SC Series array. If using the same subnet is not
possible, the iSCSI fault domain on the SC Series array must be properly routed to the subnet where the PS
Series or MD3 array resides.
A minimum of one Fibre Channel (FC) fault domain is required to use the Thin Import process to import data
from an FC-connected MD3 array. Host bus adapters (HBAs) on the MD3 and SC Series arrays must be
zoned to allow communication between the two arrays.
Note: The zone must include both MD3 controllers and the physical (not virtual) Fibre Channel ports on the
SC Series array in order to access volumes on each controller.

System Deployment Guide on Dell.com/Support.
