Introduction 1 Introduction This document provides an overview of the Dell EMC™ SC Series Thin Import feature, and introduces best practice guidelines and additional guidance for migrating data from a Dell™ PS Series or PowerVault™ MD3 series array to an SC Series array. Thin Import functionality was included as part of the Dell Storage Center Operating System (SCOS) 6.7 release and was enhanced to include VMware® support in SCOS 7.0. Support for importing from a PowerVault MD3 array was added in SCOS 7.
Overview and requirements 2 Overview and requirements The Thin Import process allows copying data from an external device and placing it onto an SC Series array. This process works at a block level and uses synchronous replication to import the data. When the source LUN is thin provisioned, all blocks on the source LUN are read and then written to the target volume on the SC Series arrays with the exception of zeroed blocks, which are not actually committed to disk.
Overview and requirements 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.
Overview and requirements 2.3 MD3 array requirements To import data from an MD3 array, the SCOS version must be 7.2 or higher. Supported MD3 models and firmware requirements are detailed in the following table: Model Minimum firmware version MD32xxi 08.20.21.61 MD36xxi 08.20.21.61 MD36xxf 08.20.21.61 MD38xxi 08.25.09.61 MD38xxf 08.25.09.
Overview and requirements By default, iSCSI initiators that use discovery try to log in to group targets protected by CHAP, even if they do not have the correct access credentials. In the case of Thin Import, when a remote connection is created from an SC Series to a PS Series array, the SC Series initiators automatically discover and try to connect to the VDS/VSS target on the PS Series array. Authentication to the VDS/VSS target will fail, causing all other connections to the array to drop and reconnect.
Overview and requirements 3. In the iSCSI Discovery section, click to enable the filter, Prevent unauthorized hosts from discovering targets. 4. Click the Save icon.
Preparing PS Series volumes for import 3 Preparing PS Series volumes for import This section details how to create a remote connection from the SC Series array to an iSCSI-connected PS Series array. 3.1 Configuring volume access SC Series arrays are granted access to the PS Series volumes by specifying permission to one or more of the following endpoints: IP addresses of SC Series iSCSI initiators, or SC Series iSCSI initiator (IQN) names.
