[openstack-dev] Information Dispersal Algorithm implementation in OpenStack

2014-11-10 Thread Aniket K
Dear Team, In OpenStack Swift, built-in replication technique is used to provide 3x+ data redundancy that is enabling OpenStack to provide high availability. We are studying use of Information Dispersal Algorithm(IDA) as a technique instead of replication to provide high availability along

I've never read that paper before and can not find a free copy online. Based on the abstract it seems to be a parity based algorithm (erasure codes) and would not be directly applicable to replication based dispersion/data placement. There is current work to enable an erasure code scheme for data
