Precautions for creating a remote link for a V3 series unified storage system
The precautions for creating a remote link for a V3 series unified storage system V300R002 are as follows: 1. If a Fibre Channel network is used, set Link Type to FC. If an IP network is used, set Link Type to iSCSI. 2. If the storage systems at the two ends are of different versions, initiate link creation from the storage system with the later version. Otherwise, the link creation fails.

RAID levels supported by unified storage systems
RAID policies (levels) supported by unified storage systems: 0, 1, 3, 5, 6, 10, 50

Value-added features supported by eDevLUNs
After V3 series unified storage systems use the SmartVirtualization feature to take over external LUNs and create eDevLUNs, the eDevLUNs can be used as local LUNs. The eDevLUNs support the following value-added features: snapshot, remote replication, SmartMigration, and volume mirroring, SmartQoS, SmartPartition, SmartCache, multi-tenant, and HyperMetro.

Functions of the intelligent acceleration module in SmartDedupe&SmartCompression
SmartDedupe&SmartCompression occupy CPU resources that are not used by other applications to compute fingerprint information, compress data, and decompress data. Therefore, if deduplication and compression are performed on more LUNs simultaneously, the impact on system performance is greater. After the intelligent acceleration module is installed, you can transfer the related operations to hardware to release system resources. It is recommended that you contact Huawei technical support to determine whether to install the intelligent acceleration module.
