US 2006/0069861 A1 · METHOD AND APPARATUS FOR STORAGE POOLING AND PROVISIONING FOR JOURNAL BASED STRORAGE AND RECOVERY

Abstract

A set of interconnected storage systems supporting different types of storage devices and different performance attributes are intelligently applied to process types, such as journal entries. The processes are ranked according to a predetermined priority ranking. Storage devices in the storage system having similar performance attributes are pooled and ranked according to their performance attributes. The highest priority process is matched with available logical devices from available storage pools that rank highest in the processes performance priority. A cache is similarly allocated from the highest ranking access speed logical devices.

Dependent claims

A method of allocating storage space to a series of processes, comprising the steps of:

determining a process N comprising the highest priority of the series of processes among a predetermined priority of the processes;
selecting a storage pool R comprising a highest ranking storage pool among a plurality of storage pools for the process N, said storage pools being ranked according to capacity, reliability, and an access rate;
assigning any available devices from the storage pool R up until an amount of storage space in the assigned available devices meets or exceeds a required storage capacity of the process N, said storage capacity including capacity, reliability, and an access rate;
if the available devices from the storage pool R do not meet the required storage capacity of the process N, then substituting the storage pool R with the next highest ranking storage pool among the plurality of storage pools for the process N and repeating the steps of selecting and assigning until the required storage capacity of the process N is met.
