We're looking at moving 287gb (~10.7m inodes) worth of data from a 630 to a clean volume on a 760.

To schedule the downtime, I need to know if anyone has ballpark figures for calculating the tiem for a volcopy. The filers are well connected (gbit ether on both of them), and I can sacrafice big chunks of performance to make this go in a timely manner. (the 100mbit interfaces are inactive as well, if those should just be strapped together)

Later on, we're looking at trying to snapmirror 536gb (~17.2m inodes) spread pretty evenly across two volumes between two locations. Are there numbers available on the approximate overhead of the snapmirror protocol (delta bytes * overhead), and how often it would be feasible to run it (I'd prefer something in the neighborhood of 5-10 minutes).

The best numbers I could find on NOW were "36GB/hr will drive the cpu to 100%" without any reference to the filer model, cache sizes (the filer does do read-aheads, right?), inode density, etc...

thanks.
