Functional
- Array configurations
All-flash, hybrid or HDD arrays
Storage format

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 deduplication and compression
Selectable option per volume on SSD and/or HDD tiers in hybrid configurations
Compression-only option also available on any configuration
HDD optimization
FastTrack moves frequently accessed data to outer tracks for quicker response times
Data Mobility and Migration
- Replication
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) 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 Protection
- Data Protection, Disaster Recovery, Security
Business continuity
Live Volume bi-directional auto-failover, auto-repair
Continuous operations, disaster recovery, disaster avoidance
Includes third-site (tertiary) replication options with Live Volume Managed Replication
Zero RTO/RPO with customizable site failover SLAs per volume
Does not require identical hardware at each site
VMware Metro Stretch Cluster support
VMware Site Recovery Manager
Thin snapshots
Records changes only, snapshots auto-migrate to lower-cost storage
Replay Manager
Application-consistent snapshots in Microsoft or VMware environments
Data-at-rest encryption
Self-encrypting drives (SEDs) in SSD or HDD formats
Full Disk Encryption (FCE) based on AES-256
Drives certified to FIPS 140-2 Level 2
Key Management Server (KMS) options available for FIPS 140-2 Level 1, 2 and 3

Management
- Management interface
Dell Storage Manager
Multi-array, multi-site, cross-platform management from single interface
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. Federate like or unlike arrays: SC9000, SC8000, SC7020, SC5020, SC4020.
