What is the maximum volume or aggregate size that can be created with an Isilon Scale- Out NAS system?

An Isilon customer implemented a retention period at the directory level. They set individual retention periods on individual files within those directories.
Which retention periods will be enforced?

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.
-- Exhibit --
The customer will add two more Illumina Hi-Seq Sequencers in the next 6 months.
Once these are added, what is the total amount of data from all the sequencers they can
expect to add per month?

Which type(s) of data is predominately associated with home directories and file shares?

Independent of protocol, what does Isilon OneFS use to translate identities?

What is the best case performance for Backup Accelerator when backing up to LTO-4 or LTO-5 drives?

A company currently has numerous file servers providing home directories for its
employees. Some departments have their own file servers. All corporate users authenticate
using Active Directory. The engineering department has their own untrusted AD domain for
their file servers.
The company is looking for a consolidated solution that requires minimal changes to the
environment, and that creates a single namespace for the home directories.
What is the recommended solution that will meet this company's requirements?

What is the minimum number of nodes in an Isilon cluster for N+2 protection?
