OneFS high availability and data protection suite

  • Data Protection: Described in detail earlier, at the heart of OneFS is FlexProtect. This unique, software-based data protection scheme allows differing levels of protection to be applied in real time down to a per-file granularity, for the entire file system, or at any level in between.

    Redundancy: As we have seen, the Dell PowerScale clustered architecture is designed from the ground-up to support the following availability goals:

    • No single point of failure
    • Unparalleled levels of data protection in the industry
    • Tolerance for multi-failure scenarios
    • Fully distributed single file system
    • Proactive failure detection and preemptive, fast drive rebuilds
    • Flexible data protection
    • Fully journaled file system
    • High transient availability
    • Nondisruptive upgrades and operations

    The following diagram illustrates how the core components of the PowerScale data protection portfolio align with the notion of an availability and protection continuum and associated recovery objectives.
