Jeff,

We did a local volcopy, moving data from one volume of 18GB FCAL drives to another volume of 36GB drives. It was all internal to the filer. We only have one FC-AL adapter on our F740.

We got some volcopy specs from NetApp and the max write speed was something like 18MB/sec for sequential writes. If you did 180GB in 1hr and 20 min, that is around 33MB/sec. How did you manage that?

Thanks John

c) If you upgrade disks/shelves in the future, you will  likely do

it a

...

volume at a time. We did this with a volume with 180GB  and the

volcopy took

...

6-7 hours to complete.  It is NOT very fast.  With  400GB+ in a

volume, that

...

should be 2-2.5x longer.

How did you run the volcopy? Over the network or local inside a single filer? What kind of head(s)?

We've found volcopy to be extremely fast, especially for upgrading disks and/or migrating data. In fact, we used volcopy to relocate and

replicate

a huge chunk of data when Louis' company and ours split and it was a life saver. We were using F760's, but it took about 1 hr. 20 minutes to volcopy ~180GB. That was all in one head that had both a FC-AL adapter

and

dual SCSI adapters.
