DdlRT leverages two orthogonal arrays to build a two-level mapping across racks and nodes, deterministically placing stripes on designated storage nodes, which avoids or significantly reduces transition traffic while preserving load balance at both the rack and node levels.

Erasure coding is widely used in distributed storage systems because it provides high reliability with low storage overhead. To adapt to changing performance and reliability requirements, systems may perform redundancy transition on erasure-coded data, i.e., re-encoding existing data on the fly with new coding paramete...
