Dell SC All-Flash Storage Arrays

Welcome to a better flash architecture

Smart AFA choice for modern workloads provides self-optimizing performance, federated scale and mobility, all-inclusive software value

Data Mobility and Migration

Replicates with other SC Series arraysi
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) 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

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

Auto-tiering structure
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
Compression-only option also available

Dell Storage Manager (multi-array, multi-site, cross-platform management)


Create large multi-array systems under unified management, with seamless workload migration between arrays via included Live Migrate feature. Add like or unlike 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.i
