Data is CERN’s most precious commodity. Quantum StorNext is instrumental in collecting that data quickly and reliably, thereby enabling the scientific community to understand and exploit new ideas and discoveries.
Accelerating Scientific Discovery With Stornext
Stornext帮助Cern加速粒子研究
探索宇宙的起源时，管理大规模的数据可以是银河系任务。经过大量的研究和测试，CERN，世界领先的粒子物理实验室，选择StorNext软件进行数据管理。结果：A system that allows voluminous data to be accessed and shared in a high-performance computing environment.
Billions of Data Bits Every Second
在CERN中，欧洲核研究组织总部位于瑞士，其中一项实验被称为Alice（大型离子碰撞器实验）。Alice致力于通过加速粒子来研究物理物理学，并涉及来自30个国家的1000多名物理学家，工程师和技术人员的国际合作。他们共同有助于解决基本物理中最早的挑战之一：讲述物质的诞生。
使用探测器，Alice收集由颗粒碰撞产生的大量数据。Pierre Vande Vyvre是Alice数据采集的项目领导者，任务是使用摇滚固体数据采集，选择，传输，存储和处理的信息管理系统，以管理每秒生成的数十亿位数据。
为了进一步复杂化要求，Alice实验距离Cern的主电脑中心距离Cern的主电脑中心，其中数据位于大容量存储系统上。数据采集过程中的另一个挑战是Linux文件系统到位不足以在节点之间快速且轻松地共享数据。
福利：快速，有效的数据采集
The CERN team investigated several different options available for a clustered file system (CFS). The main requirements for the CFS were maximum aggregate bandwidth performance; a minimal footprint for the hardware equipment (the ALICE Data Acquisition room was fairly small); scalability to manage the volume of clients (up to 100 user nodes); and—most importantly—independence between the CFS and the underlying hardware.
After several weeks of thorough testing, the team selected StorNext. During the initial stage of implementation, the team began with one server, one client, and one disk array. The system now consists of 180 Fibre Channel 4G ports and 75 transient data storage arrays. There are 105 nodes accessing data over Fibre Channel. The ALICE storage architecture also has 90 StorNext distributed LAN clients accessing data over IP.
Stornext的主要福利之一来自其亲和力功能。该功能允许团队通过写入亲暗的关联关系点来将数据引导到特定的主要磁盘。这意味着所有机器都可以随时以最大性能运行。
“StorNext is delivering the high-speed, shared workflow operations and large-scale, multi-tier archiving required by ALICE,” said Vande Vyvre.
