摘要：
From a user perspective in modern data centers, temporary data unavailability dominates permanent data unavailability. Complementing data center repair research, this paper focuses on this temporary unavailability. To help manage this traffic-induced unavailability, we propose a coded resolution-aware storage ( CRS) scheme for data center video-streaming applications. In particular, files stored on drives are pre-network coded across multi-resolution ( MR) layers. We explore the characteristics of this concept and compare it to an uncoded resolution-aware storage ( URS) scheme, as well as to classic storage systems. We illustrate that the CRS scheme can in some cases provide an order of magnitude in saturation probability gains over URS and classic systems.
