Center, Chinese Academy of Sciences Robust IBM XIV storage solution empowers and safeguards China’s inroads in science Founded in 1949, the Chinese Academy of Sciences (CAS) is the Overview chief scientiﬁc institution of the State Council of China, and serves as a national hub for scientiﬁc innovation. A well-known and respected The need entity, the Academy is a driving force in the ongoing reform of China’s With data growth rates exceeding the national scientiﬁc and technological systems. Based in Beijing, with CAS’ ability to manage critical informa- tion, the Academy required a solution that 1,000 ﬁeld stations across the country, it has a workforce of more than would support present and future storage 50,000 individuals. requirements with performance and relia- bility while also lowering costs. The CAS has experienced enormous growth in its data volumes in The solution recent years, due in part to its research teams’ increasing use of advanced With the help of IBM, the CAS created a technology tools, fueling sophisticated research and data collection. Its cloud storage solution featuring the scientists also needed quick access to the stored data for analysis.

The Academy and compared several repurposed its existing mid-range storage devices to serve as a second tier high-end storage arrays under the XIV system, and installed an IBM System Storage® TS3500 Tape Library for data backup and offline archive. To enable global from different vendors, name space and simultaneous parallel ﬁle access from multiple nodes, and our tests showed the CAS implemented IBM Scale Out File Services (SOFS), based on IBM General Parallel File System™ (GPFS™). The CAS is the that the IBM XIV ﬁrst organization in China to use the XIV system with IBM SOFS.

Academy of Sciences “We were also conﬁdent that the XIV system would deliver the high I/O we needed. Thirdly - and this was the most attractive feature—we felt that the user-friendly management interface on the XIV system would provide low total cost of ownership.” The IBM SOFS environment is hosted on ﬁve IBM Power Systems servers running IBM AIX® and Red Hat Enterprise Linux, and also on four IBM System x3650 M2 servers running Red Hat Enterprise Linux. This environment provides high-speed simultaneous access to ﬁles, regardless of the client operating system, and virtually unlimited scalabil- ity. IBM Global Technology Services assisted the CAS in designing and deploying the new cloud storage solution. Smooth integration With the IBM XIV Storage System as the top tier in its storage cloud, the CAS has achieved its objectives of extremely high performance and availability for storage at low management cost. Equally, the advanced grid architecture of the XIV system is a perfect ﬁt with IBM SOFS, supporting high-speed parallel access from multiple nodes. 2
