Data Mobility and Migration

Replication
Replicates with other SC Series arrays*
Synchronous/Asynchronous via FC or iSCSI
Per-volume QoS bandwidth prioritization
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) 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

Auto-tiering method 
Policy-based migration based on real-time data usage, customizable 512KB-4MB page size.

Auto-tiering structure
Up to 3 primary (media-based) tiers total, up to 2 SSD tiers (write- and read-intensive SSDs)

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 compression
Selectable option per volume 
Applies to SSDs, HDDs or both in hybrid configurations

HDD optimization
FastTrack moves frequently accessed data to outer tracks for quicker response times

Federation 
Create large multi-array systems under unified management, with seamless workload migration between arrays via included Live Migrate feature. Add arrays non-disruptively, efficiently utilizing their combined capacity and performance. Volume Advisor monitors federated arrays to suggest optimal data placement and load balancing. Volume movement does not impact snapshots or replication data protection.*
