A family of optimal locally recoverable codes
Itzhak Tamo, Alexander Barg
A code over a finite alphabet is called locally recoverable (LRC) if every symbol in the encoding is a function of a small number (at most ) other symbols. We present a family o…
An Improved Sub-Packetization Bound for Minimum Storage Regenerating Codes
Sreechakra Goparaju, Itzhak Tamo, Robert Calderbank
Distributed storage systems employ codes to provide resilience to failure of multiple storage disks. Specifically, an MDS code stores symbols in disks such that th…
Access vs. Bandwidth in Codes for Storage
Itzhak Tamo, Zhiying Wang, Jehoshua Bruck
Maximum distance separable (MDS) codes are widely used in storage systems to protect against disk (node) failures. A node is said to have capacity over some field ,…
Optimal Locally Repairable Codes and Connections to Matroid Theory
Itzhak Tamo, Dimitris S. Papailiopoulos, Alexandros G. Dimakis
Petabyte-scale distributed storage systems are currently transitioning to erasure codes to achieve higher storage efficiency. Classical codes like Reed-Solomon are highly sub-optim…
