The F760 could have at most:

168 9GB disks for total Raw/unformatted capacity of 1.4TB (Minimum 3 loops of 56 disks) or

84 18GB disks for a total Raw/unformatted capacity of 1.4TB (Minimum 2 loops, can have no more than 56 drives on one loop) or

42 36GB disks for a total Raw/unformatted capacity of 1.4TB (Minimum 1 loop. More loops can be added if desired).

So on a F760 I can have 56 32GB drives on one fibre loop? Is any performance lost here?

Thanks Jason

This question should really be addressed to your local NetApp sales person or SE, however:

...

Is the maximum storage per fibre loop still 464.4GB?

No.

The maximum storage per F760 is presently approx. 1.4TB raw disk space. This can be on one loop or more than one loop, in whatever config you require, subject to a maximum of 56 devices per loop.

I think this number is correct, but I'd rather have you hear it from a NetApp person. Besides, I though they were 36GB drives. As per performance, of course, there is bus arbitration overhead to start. Also you're talking about putting in huge drives, which maximum input/output is still about the same as the smaller drives. Drive performance hasn't improved all that much while capacity has increased significantly.
