Hi,
Is the difference between copying files on these two options?
1.- A volume configured as CIFs in filer FAS2240A-4 (smb2 active) . A 5000 Copying files from one server to filer through 1GB network: 4 minutes
2.- A 5000 Copying files from one server to a shared folder on another server: 30 seconds.Machines: Windows 2008 R2 SP1Thanks

    Was this the order of your test?  If so, the data for the second copy was likely still in cache, while for the first copy it would have had to have been read from disk.  You'd need to clear the buffer cache to ensure make the tests equal.  Alternatively, you could run test 1, test 2, then run test 1 before - if the data was already in the buffer for test 2, then it still should be for the second test 1.

    For test 1 - is it going from local disk on the server to the filer?

    For test 2 - is it from local disk on server A to local disk on server B?

     

    Are the servers / filers on the same network configuration - subnet or hop count?

     

    Would there be any other major activity happening on the filer at the test time? What is the aggregate layout on the filer?

      For test 1 - Correct

      For test 2 - Correct

       

      Are the servers / filers on the same network configuration - subnet or hop count?: some subnet (no firewalls)

       

      Would there be any other major activity happening on the filer at the test time? What is the aggregate layout on the filer?:

      It is made ​​only in that test, not in production yet.

       

      thanks
