摘要

Many public and privately funded data centers host supercomputers for running large scale simulations and analyzing experimental and observational data. These supercomputers run usually tightly coupled parallel applications that require hardware components that deliver the best performance. In contrast, commercial data centers, such as Facebook and Google, execute loosely coupled workloads with a broad assumption of regular failures. The dimension of the data centers is enormous. A 2013 article summarizes commercial data centers' dimensions [1]. It estimates, for example, that Facebook hosts around 100 PB of storage and Google and Microsoft manage around 1 million servers each - although the hardware is split among several physical data centers - a modus operandi not suitable for HPC centers. With the hunger for information, the globally installed storage capacity increases exponentially and is expected to hit 7,235 Exabytes by 2017 [2]. This trend is visible in the sales reports of companies such as the disk drive manufacturer Seagate. Within 5 years, they shipped 1 billion HDDs, which means 700.000 units every day [3]. With state-of-the-art 8 TB disks, this would already account for 5.5 exabyte of capacity by day.
