相当长一段时间以来，计算系统服务器，无论是低功耗还是高端设计，都是围绕一个共同的设计原则创建的：主板及其硬件组件形成一个基线，整体构建块，其余的硬件/软件堆栈设计建立在此基础上。这种计算/内存/网络/存储资源的比例在设计时是固定的，并且在整个机器生命周期中保持静态，在系统资源利用率低、昂贵的升级周期和降低的能量比例方面具有已知的后果。通过实现分解的概念，打破服务器的界限，dReDBox接受了革新低功耗计算市场的挑战。除了为下一代数据中心提出高度模块化的软件定义架构外，dRedBox还将指定，设计和原型化一种新颖的硬件架构，其中基于soc的微服务器，内存模块和加速器将放置在通过高速，低延迟光电系统结构相互连接的独立模块化服务器托盘中，并在适合用途的资源/电源管理软件驱动下分配任意集。这些模块将采用最先进的低功耗组件，并适用于各种集成形式因素和目标场景的部署。dRedBox旨在提供一个成熟的、垂直集成的数据中心原型，以展示分解在可扩展性、效率、可靠性、性能和节能方面的优势，这将在三个试点用例中得到证明。
For quite some time now, computing systems servers, whether low-power or high-end ones designs are created around a common design principle: the main-board and its hardware components form a baseline, monolithic building block that the rest of the hardware/software stack design builds upon. This proportionality of compute/memory/network/storage resources is fixed during design time and remains static throughout machine lifetime, with known ramifications in terms of low system resource utilization, costly upgrade cycles and degraded energy proportionality. dReDBox takes on the challenge of revolutionizing the low-power computing market by breaking server boundaries through materialization of the concept of disaggregation. Besides proposing a highly modular software-defined architecture for the next generation datacentre, dRedBox will specify, design and prototype a novel hardware architecture where SoC-based microservers, memory modules and accelerators, will be placed in separated modular server trays interconnected via a high-speed, low-latency opto-electronic system fabric, and be allocated in arbitrary sets, as driven by fit-for-purpose resource/power management software. These blocks will employ state-of-the-art low-power components and be amenable to deployment in various integration form factors and target scenarios. dRedBox aims to deliver a full-fledged, vertically integrated datacentre-in-a-box prototype to showcase the superiority of disaggregation in terms of scalability, efficiency, reliability, performance and energy reduction which will be demonstrated in three pilot use-cases.
