You have to think of ways to exercise the various components.
For the disk, you can try various IO benchmarks, or you can use dd to
copy various large files around.
For the NIC, you want send and/or receive data as quickly as possible.
You'll also want to have some disk I/O in there in case bus contention
comes into play. If you have a non-XFS partition on the SW RAID drive,
you can scp a large file from it to another machine's /dev/null.
With more details about your hardware configuration, we can probably
come up enough tests to find your problem.
