论文摘要
高性能对象存储是一种新兴技术，它在HPC存储领域提供了替代解决方案，由于过度的一致性保证和元数据处方性，它有可能解决传统分布式POSIX文件系统中长期存在的可伸缩性问题。 在本文中，我们评估了在标准文件系统中存储类似对象数据的性能，其中配置和访问机制尚未针对对象访问行为进行优化，并与使用对象存储系统的好处进行比较和研究。 虽然这种方法并未以标准方式利用文件系统，但这项工作使我们能够调查基础存储技术性能是否比文件系统或对象存储提供的软件接口和基础架构更重要。
High-performance object stores are an emerging technology which offers an alternative solution in the field of HPC storage, with potential to address long-standing scalability issues in traditional distributed POSIX file systems due to excessive consistency assurance and metadata prescriptiveness. In this paper we assess the performance of storing object-like data within a standard file system, where the configuration and access mechanisms have not been optimised for object access behaviour, and compare with and investigate the benefits of using an object storage system. Whilst this approach is not exploiting the file system in a standard way, this work allows us to investigate whether the underlying storage technology performance is more or less important than the software interface and infrastructure a file system or object store provides.
