Exact-repair trade-off for (n, k = d − 1, d) regenerating codes
Mehran Elyasi, Soheil Mohajer · 2017
A class of exact-repair regenerating codes is introduced for a distributed storage systems with parameters (n, k = d - 1, d). The proposed construction uses determinant codes as building blocks. The proposed codes can be generated for k different operating points (α, β) on the trade-off, including the MBR and the MSR points. The trade-off achievable by the proposed code is strictly below the state-of-the-art codes, and more importantly, does not depend on n, the total number of nodes in the system. The field size required for the construction is only Θ(n).
