Pooled partition layout and representation

A system for organizing a storage set, the system comprising:

• a partition manager configured to create a pooled partition having data that is distributed among at least two partitions of at least one storage device, the two partitions occupying less than all of the physical capacity of at least two storage devices, the pooled partition comprising:
• extents that are located in the at least two partitions and including:
• a first extent within a first subrange of the physical storage capacity of a first storage device of the storage set, and
• a second extent within a second subrange of the physical storage capacity of a second storage device of the storage set, where the second storage device is different from the first storage device;
• and
• configuration data stored within the pooled partition, the configuration data identifying the at least two storage devices comprising the pooled partition.

A storage device configured to provide physical storage capacity to logical storage capacity for at two spaces, the storage device comprising:

• a partition comprising a range of physical storage capacity;
• and
• a partition configuration stored within the partition and identifying:
• a first extent comprising a first subrange of physical capacity within the partition that is allocated for logical storage capacity of a first space of the partition;
• and
• a second extent comprising a second subrange within the partition that does not overlap the first subrange, and where the second extent providing physical storage capacity allocated for logical storage capacity of a second space that is different from the first space of the partition.
