Abstract
Aspects of the innovations herein are consistent with a storage system for storing variable sized objects. The storage system may be a transaction-based system that uses variable sized objects to store data. The storage system may be implemented using arrays disks that are arranged in ranks. Each rank may include multiple stripes. Each stripe may be read and written as a convenient unit for maximum performance. A rank manager may be provided to dynamically configure the ranks to adjust for failed and added disks by selectively shortening and lengthening the stripes. The storage system may include a stripe space table that contains entries describing the amount of space used in each stripe. An object map may provide entries for each object in the storage system describing the location (e.g., rank, stripe and offset values), the length and version of the object.
