To meet its customers’ needs for unlimited data scaling, Baidu AI Cloud engaged experts from IBM to plan, design, deploy and configure a future-ready cold data storage architecture that consists of IBM TS4500 Tape Libraries and the IBM Storage Scale and IBM Storage Defender solutions.
“Different types of data use scenarios put different demands on our storage system,” explains Miao Yu. “For example, high-performance computing workloads require high throughput and low-latency read and write access. For other use scenarios, such as storing log files generated by our monitoring systems, we must be able to retrieve data rapidly even if years have passed since it was stored. We looked for a cold storage solution with greater cost-efficiency, high IOPS and 24x7 availability—and IBM delivered.”
The IBM solution integrates with Baidu AI Cloud’s existing distributed storage architecture. IBM TS4500 Tape Libraries for cold data storage are used with legacy solid-state drives for hot data and hard-disk drives for warm storage. Data moves seamlessly across the tiered storage system, enabling high-performance access. What’s more, tapes can be retained for over 30 years at a much lower cost than disks.
“We were impressed with the IBM solution,” says Miao Yu. “With IBM Storage Scale, we can let data flow freely across our environment, while at the same time simplifying our storage architecture for easier management and maintenance.”
To ensure that the new platform met Baidu AI Cloud’s long-term requirements for scalability, IBM experts created automated deployment workflows. These allow 20 cold storage nodes to be provisioned in a single batch, significantly accelerating both deployment and expansion.
IBM also helped Baidu better adapt and integrate data from the IBM tape storage solution with its own platform, enabling Baidu to rapidly identify and resolve issues and bring the solution online. To date, Baidu has deployed 14 IBM TS4500 Tape Libraries at its Yangquan data center, storing more than 2 EB of cold data.
Miao Yu elaborates: “IBM met and exceeded all our core selection criteria, and after a successful proof of concept we were certain that IBM TS4500 Tape Libraries with IBM Storage solutions would be the perfect way to solve the cost and space pressures we faced around disk storage. We have a long and successful history of collaboration with IBM on other projects, and this gave us the confidence that IBM has the technical innovation and services to address the challenges of deploying a large-scale storage solution.”
