Embodiment Construction

[0025] figure 1 An embodiment of a standard storage element 10 including an upper interface 12, possibly to a higher level SRE, is shown. The information 11 available at this interface includes the accumulated free storage space made available by this SRE and the average reliability of this free storage space. This information is derived from information available from the storage units 13 , 17 and 18 that are part of the standard storage element 10 . Each storage unit includes at least three fields, namely available free storage space, storage unit reliability index and at least one pointer 14, 15 and 19 pointing to the physical storage location. This physical storage location may be remote 14, 19, such as within another SRE, or local 15, such as within a hard drive 16 that is part of the local SRE. Pointers can be implemented as IP addresses associated with physical storage devices.

[0026] Depending on the information that can be obtained from the storage unit, there ar...

Abstract

The present invention relates to the reliable storage of data within a distributed storage system. A method and system for storing a data unit within a distributed storage system is disclosed, wherein the distributed storage system comprises a plurality of storage elements of unspecified system reliability, a public network interconnecting the plurality of storage elements and a reliability index control unit measuring a plurality of storage element reliability indexes associated with the plurality of storage elements. The data unit is stored following the steps of receiving a request to store the data unit according to a data unit reliability index and storing replicated copies of the data unit in at least one storage element, such that the data unit reliability index is achieved.

Description

technical field [0001] The invention relates to reliable storage of data in a distributed storage system. Background technique [0002] In order to provide reliable storage of data, many systems have been proposed in the prior art. Such systems differ in many respects with respect to storage media, such as tape, magnetic disk, flash memory, etc., or technical characteristics, such as access speed, portability, storage capacity, rewritability and reliability. In particular, reliability is an important function and storage systems utilize different methods to achieve this reliability. [0003] One well known method is Redundant Array of Independent Drives (RAID). RAID is an umbrella term for computer data storage schemes that divide and replicate data across multiple hard drives. Various designs of RAID balance or emphasize two key design goals: enhanced data reliability and enhanced I / O (input / output) performance. Various standard schemes have evolved, known as RAID level...
