Wide-stripe erasure codes, with tens to over a hundred data chunks per stripe, offer high reliability at low storage overhead. Existing wide-stripe designs that are based on scalar codes (e.g., LRCs in Google and Azure) reduce _repair traffic_ but increase _storage overhead_. Although vector code...

Minimum Storage Regenerating (MSR) codes have strong potential for building efficient and reliable storage systems due to their excellent fault tolerance and low repair bandwidth. However, to meet MSR code constraints and optimize storage performance, systems often adopt large chunk sizes. This l...
