Abstract
- Codes with availability allow us to access any code symbol simultaneously t times using t disjoint recovery sets in distributed data storage. Codes with availability that are studied in the literature provide availability for individual code symbols in the codeword. In this letter, we consider a new class of codes with availability. These codes provide availability t for subsets of code symbols called multi-symbol sets. For these codes, an upper-bound on the minimum Hamming distance is derived. A construction for optimal codes with information multi-symbol availability is given. The optimal codes with multi-symbol availability allow us to access more symbols locally with the same locality, when compared to optimal codes with individual code symbol availability.
