No, not one time, rather constant data flow. I am not a storage folk so I don't have the accurate estimation of the 
data volume, but since they are data centre data so the TB will be appropriate scale.

I was asked to evaluate the VPN option, but I am hoping there are someone here doing the data encryption not at network 
layer, for example, if you are using NetApp, can NetApp encrypt the data blocks before sending them to the network, 
rather than letting VPN appliance to encrypt data  packets by packets?

We need to transfer large volume of data centre data

For what definition of "large"? Gigabytes? Terabytes? Petabytes?  And what
are the timing constraints?  There's a big difference between "one-time copy
of 15 terabytes that can run another 6 hours without breaking anything" and
"we need to move 15T in 4 hours every night to meet an audit requirement".
