Feature-rich, Easy-to-use SAN

Highly Available Architecture

No Single Point of Failure Design Provides Continuous Data Availability

Storage Center is architected for high availability with fully redundant hardware and advanced failover features. Clustered controllers provide a high level of availability by operating in unison yet connecting independently to ensure no single point of failure.

Clustered Architecture



Architected for high availability, Compellent features:

Full Redundancy: Provide continuous access to data with dual paths from servers to disk drives, fully redundant power and fans and controller failover support with single or dual HBA.

Scalable, Clustered Architecture: Achieve higher availability by adding controllers in a dual clustered configuration.

Continuous Availability: Ensure uninterrupted data access with non-disruptive software upgrades and no single point of failure architecture.
Key Benefits
  • Automatic controller failover provides high resilience
  • Controller clustering delivers higher availability than traditional implementations
  • Multi-path I/O failover requires no special software
  • Mirrored, battery backed cache for increased data protection
  • Non-disruptive software upgrades provide continuous data availability

The Compellent Advantage
CompellentOthers Typically
Clustered controller architecture (no shared backplane)Limit controllers to redundant pairs where controllers failover only between two nodes. Controllers sharing a backplane have a shared point of failure
Clustered Multi-path I/O softwareRequire custom path failover software
Non-disruptive software upgradesRequire downtime for software upgrades
Customer Testimonial
“We’ve upgraded our Compellent SAN more than 20 times without a forklift upgrade.”
