【 摘 要 】

We describe the Jasmine mass storage system, in operation since 2001. Jasmine has scaled to meet the challenges of grid applications, petabyte class storage, and hundreds of MB/sec throughput using commodity hardware, Java technologies, and a small but focused development team. The evolution of the integrated disk cache system, which provides a managed online subset of the tape contents, is examined in detail. We describe how the storage system has grown to meet the special needs of the batch farm, grid clients, and new performance demands.
