  • Page 41: Maintaining Control Modules

    4 Maintaining Control Modules Different PS Series array models contain different control module types. The combination of chassis type, control module pair, and drives determines the PS Series array model number. Ideally, an array has two control modules (which must be of the same type) to avoid a single point of failure for the array.

  • Page 42: Control Module Description

    A single control module is a single point of failure. If the control module fails, the entire array (and all the volumes on it) becomes unavailable. Dell strongly recommends buying an array with two control modules, or installing a second control module in a single-controller array.

  • Page 43: Interpreting Control Module Leds

    Dell EqualLogic PS-M4110 Hardware Owner's Manual Interpreting Control Module LEDs Dual Controller Configuration A dual control module configuration eliminates a single point of failure in the array. If the active control module fails, the secondary control module takes over immediately with no interruption of service. This gives you time to replace the failed control module while your volumes and data remain accessible.
