20140258672 | DEMAND DETERMINATION FOR DATA BLOCKS - The positioning a block of data within a storage hierarchy. For the given block of data, demand statistics are accumulated for each of multiple time periods by evaluating input/output operations on the block of data during the time period and assigning a resulting demand value to the time period for that time period. This is done for multiple time periods so that the accumulated demand for a given point of time may be calculated using the assigned demand values for the previous time periods. The accumulated demand may then be used to determine a level in the storage hierarchy that the block of data should be placed. This allows for the more in-demand memory blocks to be placed in higher in the storage hierarchy. Thus, the principles described herein allow for efficient use of computing resources. | 09-11-2014 |

Then, the storage trait set is compared against the trait sets for the multiple tiers to identify a tier into which to store the file system namespace. The file system namespace is then caused to be stored within the identified tier. Thus, the file system is provided with a volume that has multiple tiers (each having different trait sets) to choose from in storing files. | 09-18-2014 |
20140280397 | HETEROGENIC VOLUME GENERATION AND USE SYSTEM - A system in which a file system may operate on a volume in which the logical address extent of the volume is divided into multiple tiers, each tier providing storage having a distinct trait set by mapping the logical addresses of the volume to appropriate underlying storage systems.

The file system may thus store file system namespaces (such as directories and files) into the tiers as appropriate for the file system namespace. A provisioning system may also be provided and be configured to provision the volume to include such tiers, and if desired, to extend the tiers. | 09-18-2014 |

Because such a simulation is typically performed a very large number of times for even one particular first and second molecule, and is further performed for different combinations of first and second molecules, the effect of reducing the number of comparisons is leveraged and can provide a significant impact on overall simulation performance. | 11-06-2008 |
