Datastore for non-overwriting storage devices

摘要

The invention pertains to a method and information handling system (IHS) for writing data to non-overwriting storage devices. A set of bands are determined per non-overwriting storage device. Then multiple pools of storage space, to which data can be written, commensurate with the determined bands are provided. A file system configured to manage the determined multiple pools of storage space and be non-WIP is provided, where the provided file system writes data to the multiple pools of storage space. The IHS includes: a non-overwriting storage device, a module for determining a set of bands per non-overwriting storage device, multiple pools of storage space commensurate with the determined set of bands and a file system configured to be non-WIP and configured to manage the multiple pools of storage space. The file system writes data to the multiple pools of storage space.

1. A method of writing data on a non-overwriting storage device comprising:
determining a set of bands per non-overwriting storage device; providing multiple pools of storage space commensurate with the determined set of bands; and providing a file system configured to be non-write-in-place (non-WIP) and manage the multiple pools of storage space, wherein the provided file system writes data to the multiple pools of storage space; wherein the provided file system is configured to maintain a separate write pointer for each pool of storage space, wherein the write pointer signifies a position on the non-overwriting storage device where data can be written.
