Distributing workload evenly across storage media in a storage array

A processor-readable medium comprising processor-executable instructions configured for:

• compiling workload information for storage components within a storage array;
• based on the workload information, determining least busy storage components and most busy storage components;
• determining that a new disk access is a random I/O (input/output);
• and
• using a least busy storage component to service the new disk access.

A method of distributing workload evenly across storage components in a storage array comprising:

• compiling workload information for each storage component within the storage array;
• based on the workload information, predicting that at least one storage component contains high-access data;
• and
• redistributing the high-access data evenly across all storage components within the storage array.

A method of distributing workload evenly across storage components in a storage array comprising:

• compiling workload information for each storage component within the storage array;
• based on the workload information, determining least busy storage components and most busy storage components;
• determining that a new disk access is a random I/O (input/output);
• and
• using a least busy storage component to service the new disk access.

A storage array comprising:

• a processor;
• two or more storage components;
• a memory having foreknowledge information stored therein;
• and
• a redistribution module executable on the processor to access the memory, determine from the foreknowledge information which data on the two or more storage components is high-access data, and redistribute the high-access data evenly across the two or more storage components.

A system comprising:

• a host computer;
• a virtual storage array to service data requests from the host computer, the virtual storage array having two or more storage components;
• and
• a redistribution module executable on the virtual storage array to access workload information, and based on the workload information, to redistribute high-access data evenly across the two or more storage components.
