Which type of link aggregation is supported with Isilon nodes?

A customer has a cluster consisting of six H500 nodes (in one full chassis and one half populated chassis) and four A200 nodes (in one full chassis). The customer wants to expand their A200 nodes.
What is the minimum number of A200 nodes and chassis the customer can add to the cluster?

A customer has eight X400 24GB RAM that supports 400 client connections today The customer plans to add 400 more clients in the next few months. They are looking at adding an A-Series node to the cluster to help with client connections.
Before they start adding client connections, what hardware change do you recommend?

An Isilon storage administrator is concerned about capacity after ingesting 200 TB of file data. They recently added more nodes to the cluster and now want to auto-balance it as soon as possible.
The cluster utilization percentages for an average 24-hour period are:
45% during 00:00 - 08:59

60% during 09:00 - 17:00

85% during 17:01 - 23:59

The administrator wants to keep cluster utilization at a minimum. Which Impact Policy settings should be used to quickly complete the job without impacting the production workload?

A potential customer is considering replacing a four year old, Linux-based NFS server with 40TB of usable capacity. The existing system supports home directories, an internal website, and a content repository for the customer's content management system. The customer is concerned about performance of any new solution because they expect to double workload in the content management system.
What tools can be used to collect performance data needed to size the new solution?
