We installed IOMeter (an open source workload generator) on eight HP ProLiant ML350 servers - each with at least two Pentium III/866-MHz processors and 1G byte of memory. Each server emulated two clients. The NS600 was configured in primary/primary mode, and 16 separate connections were created to serve as IOMeter's storage targets.

We ran two tests using a file server/client configuration, using 8K- and 16K-byte requests (consisting of 80% read/20% write data) that randomly accessed the test file.

In separate tests, we launched three denial-of-service attacks against the NS600 while IOMeter testing was in progress. For failover testing of the data movers, we removed power from the primary data mover, and recorded fail-over times. When testing failover on interfaces, we pulled the plug on the primary interface and recorded the fail-over time.
