The Data Lake concept has promised increased value to science and more efficient operations for storage compared to the traditional isolated storage deployments. Building on the established distributed dCache serving as the Nordic Tier-1 storage for LHC data, we have also integrated tier-2 pledged storage in Slovenia, Sweden, and Switzerland, resulting in a coherent storage space well above the expected for the funding committed to the Nordic Tier-1 site.

We have implemented this with an innovative automated deployment of dCache that scales well over many sites in a distributed federation. This setup optimizes for minimal local site effort, leading to a storage service that delivers increased value to scientists while at the same time reducing the cost of operations.

ARC with caching is used for computing in order to increase performance by up to 50% when reading from geographically distributed storage, as well as reduce bandwidth use.
