Computing sites need long-term retention of cool data often “data lakes” which focus on capacity but with non trivial bandwidth requirements. For many years, tape was the best economic solution but bandwidth and access needs have outstripped tape solutions. Disk can be more economically for this storage tier. The Cloud Community uses erasure based object stores to gain scalability and durability using commodity hardware. The Object Interface works for new applications but legacy applications utilize POSIX. Campaign Storage is a Near-POSIX File System using cloud storage for data and many POSIX file systems for metadata. Campaign Storage scales namespace metadata to trillions of files and billions of files in a single directory and files from 1 byte to Petabytes. This solution is now available commercially. This talk describes Campaign Storage motivation, design, and performance.
