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
Management
Management interface
Browser-based (HTML 5):
Unisphere for SC (element manager)
Unisphere Central (multi-array management)
CloudIQ (cloud-based analytics and monitoring):
Client application:
Dell Storage Manager (multi-array, multi-site, cross-platform management)
Federation
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.*
Scripting support
Microsoft PowerShell API
RESTful API
Host OS support
Microsoft® Windows Server®, Oracle® Solaris, HP®-UX, Oracle Linux, IBM® AIX®, Novell® NetWare, SLES, Apple, HPTru64, VMware®, Citrix® XenServer®, RedHat®
Third-party application integration
VMware, Oracle, Microsoft, IBM, OpenStack™, Symantec™, Commvault®, Veeam®, Docker™ -- see SC Series Management spec sheet for more details
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
Certifications
VMware vSphere Metro Storage Cluster, VMware SRM, Veritas Storage Foundations Suite, IBM VIOS Recognized, Oracle Validated Infrastructure (OVI); see Dell Storage Support Matrix for additional certifications and details
Reporting/alerts
Support assist (phone home), remote diagnostics and performance monitoring, automated alerts, reports and notifications, departmental chargeback
Firmware updates
Online, non-disruptive.* Firmware may be set to download automatically, with option to trigger installation manually if desired.

Data Mobility
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) 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
