加州大学系统在其校园与包括加州理工学院在内的加州其他一些大学之间保持着良好的网络连接，其中大多数大学的连接速度为100 Gbps。加州大学圣地亚哥分校和加州理工学院Tier2中心已将其磁盘系统连接到单个逻辑缓存系统中，两个站点的工作节点都可以访问任一站点磁盘上的数据。这一成功的安排已经实施了两年。然而，在多个物理位置一致地管理节点并不简单，需要更新所使用的操作模型。太平洋研究平台（PRP）提供Kubernetes资源库，涵盖加州和全球多个校区的科学非军事区（DMZ）的资源。我们展示了如何使用PRP集群将XCache服务从裸机部署迁移到容器中。本文介绍了我们的硬件决策背后的推理和迁移到混合环境中并在混合环境中运行的经验。
The University of California system maintains excellent networking between its campuses and a number of other Universities in California, including Caltech, most of them being connected at 100 Gbps. UCSD and Caltech Tier2 centers have joined their disk systems into a single logical caching system, with worker nodes from both sites accessing data from disks at either site. This successful setup has been in place for the last two years. However, coherently managing nodes at multiple physical locations is not trivial and requires an update on the operations model used. The Pacific Research Platform (PRP) provides Kubernetes resource pool spanning resources in the science demilitarized zones (DMZs) in several campuses in California and worldwide. We show how we migrated the XCache services from bare-metal deployments into containers using the PRP cluster. This paper presents the reasoning behind our hardware decisions and the experience in migrating to and operating in a mixed environment.
