| + | :!:**Note** Unless you have a large RAID array hard disks will not fill a 10Gb pipe. For complete testing a RAMDisk formatted for 12GB is necessary. | ||

| + | * Download NTttcp Utility and copy to 2 Windows PCs on the network. | ||
| + | * Make sure the NTttcp traffic can pass the firewall on both PCs. Specify a firewall exception for the program name. | ||

| + | |||
| + | :!:**Note** The receiver machine in this case has an IP address of 192.168.0.140. You must specify the receiver’s IP address on the server instance. | ||
