Array configurations
All-flash, hybrid or HDD arrays
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 deduplication and compression
Selectable option per volume on SSD and/or HDD tiers
Compression-only option also available
Standard replication
Synchronous/Asynchronous using FC or iSCSI
Federated multi-array systems
Live Migrate (included in base product) enables host-transparent data movement among arrays
Volume Advisor continually monitors federation to suggest optimal data placement based on custoizable capacity or performance load balancing policies
Dell Storage Manager provides data center-level viewpoint and control
Coexistence with PS Series arrays
Replication in either direction
Day-to-day management from a single interface
Thin import: space-efficient, non-disruptive data migration from PS Series arrays
