论文摘要
加利福尼亚大学系统在其所有校园之间以及包括加州理工学院在内的许多其他大学之间建立了良好的网络,其中大多数人以100 Gbps的速度连接。因此,UCSD和Caltech已将其磁盘系统加入了单个逻辑XCache系统,来自两个站点的Worker节点都可以从任一站点的磁盘访问数据。这种设置已经存在了几年,并且已经证明运行良好。但是,在多个物理位置进行淋巴结的连贯管理并不是一件容易的事,我们一直在寻找改善操作的方法。现在,Pacific Research平台(PRP)现在提供了跨越所有UC校园科学DMZ的Kubernetes资源池,我们最近将XCache服务从裸露的金属托管到容器中迁移。本文介绍了我们在新环境中迁移和运营方面的经验。
The University of California system has excellent networking between all of its campuses as well as a number of other Universities in CA, including Caltech, most of them being connected at 100 Gbps. UCSD and Caltech have thus joined their disk systems into a single logical xcache system, with worker nodes from both sites accessing data from disks at either site. This setup has been in place for a couple years now and has shown to work very well. Coherently managing nodes at multiple physical locations has however not been trivial, and we have been looking for ways to improve operations. With the Pacific Research Platform (PRP) now providing a Kubernetes resource pool spanning resources in the science DMZs of all the UC campuses, we have recently migrated the xcache services from being hosted bare-metal into containers. This paper presents our experience in both migrating to and operating in the new environment.
