| 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 | Default and 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 |
| DEDUPLICATION AND COMPRESSION | Selectable option per volume on SSD and/or HDD tiers |
| Compression-only option also available | |
| 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 with base product) enables host-transparent data movement between arrays; see also Federation section |
| Maintains snapshots/replication relationships | |
| 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, DISASTER RECOVERY, SECURITY | |
| BUSINESS CONTINUITY | Live Volume bi-directional auto-failover, auto-repair6 |
| Continuous operations, disaster recovery, disaster avoidance | |
| Includes third-site (tertiary) replication options | |
