在不久的将来，COMPASS托卡马克每次发射预计将产生数千兆字节的数据。需要一个新的存储系统来容纳和访问所有数据。它应该是可扩展的、容错的和并行的。它不应该基于专有的解决方案，以保持独立于硬件和软件制造商，最好是建立在廉价的商品硬件上。GlusterFS是一个很有前途的分布式并行容错文件系统，被选中进行测试。这项工作的目的是对一个特定的小型GlusterFS设置进行初步测试，以确认其对COMPASS存储系统的适应性。来自多个NFS客户端的聚合阅读吞吐量是经过基准测试的最重要数据之一，它随客户端数量的增加而扩展，从1个客户端略高于60 MiB/s 1开始，到6个客户端略高于300 MiB/s。
The COMPASS tokamak is expected to produce several gigabytes of data per shot in near future. A new storage system is needed to accommodate and access all the data. It should be scalable, fault-tolerant, and parallel. It should not be based on proprietary solutions to maintain independence from hardware and software manufacturers and preferably it should be built on inexpensive commodity hardware. One of the promising distributed parallel fault-tolerant file systems, GlusterFS, was selected for testing. The aim of the work was to make initial tests of a particular small GlusterFS setup to confirm its aptitude for the COMPASS storage system. Aggregated reading throughput from multiple NFS clients was one of the most important figures that were benchmarked, it scaled well with the number of clients, starting just above 60MiB/s1for 1 client and going slightly over 300MiB/s for 6 clients.
