Data Mobility and Migration
Replication
Replicates with other SC Series arrays*
Synchronous/Asynchronous via FC or iSCSI
Target/source relationships may be one-to-many or many-to-one
Supports all SC data services on source and target volumes
Change replication types and topologies on demand
Supports cross-platform replication with PS Series/EqualLogic arrays (either direction)
Volume mobility
Live Migrate (included in base product) enables host-transparent data movement among arrays; see also Federation section
Federated multi-array systems
Live Migrate (included in base product) enables host-transparent movement of volumes among arrays
Snapshots maintained/preserved during migration
Thin Import
Space-efficient, non-disruptive data migration from PS Series (EqualLogic) and MD3 arrays
Thin Clones
Clone standalone volumes with zero duplication of data
Clones maintain independent snapshots and replication
Ideal for VDI, test/dev, other applications that require discrete instances of common data
More efficient than dedupe for database copies
Data Optimization

Tiering customizations
User-defined profiles, option to ¡§pin¡¨ volumes to any tier
RAID support
RAID 0, 1, 5, 6, RAID 10, and RAID 10 DM (Dual Mirror); any combination of RAID levels can exist on a single array
RAID tiering
Auto-provisions and dynamically restripes multiple RAID levels on the same tier; no need to pre-allocate RAID groups
Thin provisioning
Active by default on all volumes, operates at full performance across all features
Thin snapshots
Records changes only, snapshots auto-migrate to lower-cost storage
Intelligent deduplication and compression
Selectable option per volume
Compression-only option also available
