FastSCP Times out when copying large files to an ESX host

I had to restore some *.vmdk files to an ESX host and I used FastSCP to perform the restore. During the copy I received a error message that connection timed out at the host. I performed the regular troubleshooting steps and made sure that the proper ports on the firewall were opened on the ESX ​host, but the copy still continued to fail.

There were some VMs that were sharing the same NIC that was used to perform the copy to the ESX host with FastSCP. I moved all of these VMs to a different NIC on the host and was able to successfully complete the copy. If you're having difficultly restoring files to an ESX host, try using a dedicated NIC in the host for your FastSCP restores. I got roughly triple the copy speed with FastSCP compared the WinSCP.
