data transferrsyncthunderbolt
I need to copy 20TB of data onto a thunderbolt array. The box where the data exists does not have a thunderbolt connection, so I will need to utilize the local 1GB network for this. (Yes, it will take forever).
I tried to use Filezilla/sftp, but it crashed when the queue grew super large. Is rsync or scp the way to go?
No.
IPhone will use the cellular connection for push notifications at any time, unless
Settings > General > Network > Cellular Data
is turned off.
Also, if the lock screen is on, then iPhone is connected to the cellular network, not wifi.
IPad is always connected to wifi, lock screen or no.
When an interface self-assigns an IP it generally means the interface isn't getting any response from your router or DHCP server. This is a feature of OS X to let the machines build an adhoc network when they cannot determine the actual network they're on -- you can put a bunch of Macs on a dumb hub and almost get them to self-organize and function with this feature.
Your router and DHCP server are going to see the MAC address listed for the device in the Network Preferences pane. Go to System Preferences -> Network and click on your Thunderbolt interface. Click on the Advanced... button and then on the Hardware tab:
That's the MAC address that your interface is broadcasting on the network when it's trying to acquire an IP on your network from your DHCP server.

rsync is a good way to go (scp is pretty much the same with fewer features). You may want to use the
-Zoption, which will enable zlib compression. Depending on how fast your drives/computer are, it may be faster than sending uncompressed, i.e. if your network link is saturated. You may also want the archive mode option,-awhich will preserve symlinks, permissions, and creation/modification times, as well as copy directories recursively. Depending on what you're copying you might want-Ewhich preserves extended attributes and mac resource forks. Finally,--progresswill show you progress information.
