We have been engaged by a research hospital to help upgrade their Isilon installation. They
currently have 12 previous generation Isilon nodes with 200TB of capacity and run on a 1Gbps
network. They currently have 6 Illumina Hi-Seq Sequencers and an HPC cluster to process data.
They would like to expand Isilon to 2PB of active data and 1PB of archive data. They use a third
party data and metadata management service (IRODs) to stage data for analysis. The Isilon
cluster is mainly used for analysis work with the HPC cluster.
