System and method for managing a storage array

A system for managing a storage array, comprising:

• a plurality of physical storage resources;
• and
• a device communicatively coupled to the plurality of storage resources, the device configured to:
• segment each of the plurality of physical storage resources into a first storage area and a second storage area;
• activate a first logical unit including each first storage area of the plurality of physical storage resources;
• place at least one designated physical resource of the plurality of physical storage resources in a powersave mode;
• activate a second logical unit including the second storage areas of some of the plurality of physical storage resources but not the at least one designated physical storage resource, such that neither the second logical unit nor any virtual resource comprising the second logical unit is presented as a logical unit to any node communicatively coupled to the plurality of physical storage resources;
• and
• store data associated with a write operation intended for the at least one designated physical storage resource to the second logical unit.

A program of instructions embodied in a non-transitory computer-readable medium and operable to, when executed:

• segment each of a plurality of physical storage resources into a first storage area and a second storage area;
• activate a first logical unit including each first storage area of the plurality of physical storage resources;
• place at least one designated physical resource of the plurality of physical storage resources in a powersave mode;
• activate a second logical unit including the second storage areas of some of the plurality of physical storage resources but not the at least one designated physical storage resources, such that neither the second logical unit nor any virtual resource comprising the second logical unit is presented as a logical unit to any node communicatively coupled to the plurality of physical storage resources;
• and
• store data associated with a write operation intended for the at least one designated physical storage resource to the second logical unit.
