Abstract
A fault tolerant, secondary storage engine (such as a RAID engine) is closely coupled with a file system to achieve greater overall throughput in storage/database applications having a mix of large, sequential access transactions and small, random access transactions. In addition, disk rebuild time may be greatly reduced using such an embodiment. A logical storage space representing a storage area in a set of non-volatile storage devices is divided into nonoverlapping storage allocation units (SAUs) such as stripes, each SAU to overlay all of the devices in the set. Different fault tolerant storage methodologies (FTSMs) are assigned to access (i.e. read/write) data in the different SAUs, respectively. An access is made to an SAU in the set responsive to an input storage request of a first or second type, respectively.
