Clarence,
IAre the disks within the same box? If not...then snapmirror is a good way to go. You might be able to snapmirror within the same box. Performance really depends on how many disks you have in the volume(s) and what kind of head (700, 800, 900) that you have.
If you are able to snapmirror, then the down time can be on the order of minutes. It has become my favorite method for moving data. I am not positive about the source and destination being on the same box though.
Rough numbers though, you could get 60MByte/sec xfer rate on 820s. If you are on 960s expect to be on the order of 120MBytes/sec. But then it does depend on how many drives in the raid group and volumes.

Hello good toaster folks
We are planning to move a huge lot of data (> 3.0 T) from our 32 GB drives to 144 GB. I am carrying out some preliminary information about the quickest path to move the data across - the first option is to use ndmpcopy and the second is to copy it from shelf to shelf over fiber. Since this is a preliminary investigation, can someone please point me to relevant resources that may be helpful? I am after statistics of transfer rates between the two and perhaps other materials that others have found useful.
I have googled and looked through past toaster archives, and most of it is either outdated or lack of relevant information.
Thanks.
Clarence.
