Importing MD3 Windows Server volumes
71 Data Migration from Dell PS Series or PowerVault MD3 to Dell EMC SC Series Storage using Thin Import | 3041-BP-EM
5. The Offline Import from External Device window appears. Click Next.
a. If a Quality of Service (QoS) definition does not exist on the SC Series array, a prompt will appear
to create one. Click Yes to continue. Clicking No will cancel the import process.
Note: The purpose of the QoS definition is to limit or throttle the bandwidth available to the Thin Import
process, because the import process will use all available bandwidth to transfer data. Allocating too much
bandwidth to the process can be detrimental to overall system performance. Allocating too little bandwidth will
cause the import process to run slowly. If possible, test the process and monitor the system performance to
determine the proper bandwidth allocation.
b. Assign a name to the QoS definition. Enter a link speed equivalent or less than the line speed of
the iSCSI network or Fibre Channel fabric connecting the MD3 and SC Series arrays. When
enabled, the Bandwidth Limited option allows daily scheduling of bandwidth allocation in one-
hour increments. Click OK when finished.
