There's a ton of info available at https://swiftstack.com/openstack-swift/. Specifically, take a look at https://swiftstack.com/openstack-swift/architecture/ for how Swift solves some of these issues.
You might also find the info at http://swift.openstack.org useful, especially http://docs.openstack.org/developer/swift/admin_guide.html. For more info on failure handling, see https://www.youtube.com/watch?v=mKZ7kDDPSIU where I went through several failure conditions and show how Swift recovers from them. There's also a much older blog post at https://swiftstack.com/blog/2012/09/13/how-openstack-swift-handles-hardware-failures/. While it might not be the academic paper you're looking for, this should give a good groundwork of info. If you have other questions, feel free to ask. --John > On Jan 30, 2015, at 12:56 PM, Behrooz Shafiee <shafie...@gmail.com> wrote: > > Hello All, > > Unfortunately, I could not find any academic paper which describes Swift in > academic terms, most of documents are user manual and general overview.
