Tiering customizations:

  • Default and user-defined profiles, option to “pin” volumes to any tier
  • RAID: RAID 0, 1, 5, 6, RAID 10, and RAID 10 DM (dual mirror); any combination of RAID levels can exist on a single array
  • Thin provisioning: Active by default on all volumes, operates at full performance across all features

Deduplication and compression:

  • Selectable option per volume on lowest tier (SSD or HDD)
  • Compression-only option also available
  • HDD optimization: FastTrack moves frequently accessed data to outer tracks for quicker response times
  • Data reduction: Policy-based deduplication and compression of cold files in NAS volumes

  • 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)(4)
  • 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
