Data storage system including unique block pool manager and applications in tiered storage

A data storage system that receives a data set from a software module, the data storage system comprising:

• a first tier storage device that stores data in a random access manner;
• a second tier storage device that stores data in a sequential access manner;
• a redundancy reducer, wherein the data set includes a first data pool and a separately-stored second data pool, the redundancy reducer subdividing the first data pool into a plurality of first data blocks and reducing the redundancy of the first data blocks, and the redundancy reducer subdividing the second data pool into a plurality of second data blocks and reducing the redundancy of the second data blocks;
• and
• a migration engine that moves one of the data blocks between the first tier storage device and the second tier storage device based on a migration parameter of the data block, the migration engine being adapted to merge the first data pool with the second data pool.

A data storage system that receives a data set from a software module, the data storage system comprising:

• a first tier storage device having a first I/O bandwidth;
• a second tier storage device having a second I/O bandwidth that is less than the first I/O bandwidth;
• a redundancy reducer, wherein the data set includes a first data pool and a separately-stored second data pool, the redundancy reducer subdividing the first data pool into a plurality of first data blocks and reducing the redundancy of the first data blocks;
• and
• a migration engine that moves one of the first data blocks between the first tier storage device and the second tier storage device based on a migration parameter of the first data block, the migration engine being adapted to merge the first data pool with the second data pool.

A data storage system that receives a data set from a software module, the data storage system comprising:

• a first tier storage device having a first access time to data;
• a second tier storage device having a second access time to data that is lengthier than the first access time to data;
• a redundancy reducer, wherein the data set includes a first data pool and a separately-stored second data pool, the redundancy reducer subdividing the first data pool into a plurality of first data blocks and reducing the redundancy of the first data blocks;
• and
• a migration engine that moves one of the first data blocks between the first tier storage device and the second tier storage device based on a migration parameter of the first data block, the migration engine being adapted to merge the first data pool with the second data pool.

A data storage system that receives a data set from a software module, the data storage system comprising:

• a first tier storage device having a first effective storage capacity;
• a second tier storage device having a second effective storage capacity that is greater than the first effective storage capacity;
• and
• a migration engine, wherein the data set includes (i) a first data pool having a plurality of first data blocks, and (ii) a separately-stored second data pool having a plurality of second data blocks, the migration engine moving one of the data blocks between the first tier storage device and the second tier storage device based on a migration parameter of the data block, and the migration engine being adapted to merge the first data pool with the second data pool.
