Expansion Capacity

  • Supported expansion enclosures
    Dell EMC SC420: 24 x 2.5” drive bays (12Gb SAS)
    Dell EMC SC400: 12 x 3.5” drive bays (12Gb SAS)
    Dell EMC SC460: 60 x 3.5” drive bays (12Gb SAS)

    Maximum drive count
    222 per array (30 internal, plus 192 external), more in federated systems1

    Max raw capacity 
    2.16 PB per array (SSD or HDD)2, more in federated systems1

    Max raw capacity (NAS)
    2.16 PB per array (requires FS8600 NAS appliance)
    4PB in single namespace (requires FS8600 and multiple arrays) 
    20PB with global namespace (requires FS8600 and multiple arrays) 

    Storage media
    SAS and NL-SAS drives; different drive types, transfer rates and rotational speeds can be mixed in the same system. 
    SSD: write-intensive and read-intensive drives 
    HDD: 15K, 10K, 7.2K RPM

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
