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.

Before making any changes, the customer would like a graphical presentation of their existing
