OSiRIS: Open Storage Research Infrastructure

OSiRIS was envisioned as a readily usable storage infrastructure for collaboration on large datasets. Building on top of the Ceph object storage platform we provide direct mount access to storage as well as object API access (S3 protocol). We allow researchers to use their local institutional credentials to manage their own identity in OSiRIS and designate VO admins who can self-organize groups and collaborative access. Our infrastructure includes monitoring and metric storage so we can track usage of resources by VO, and adaptive resource throttling for S3 clients (the still-unsolved challenges of QOS for Ceph mounted filesystems will be covered on the poster as well).
