Maximum 450 GB disks in an aggregate with 7.3.1+?

This page is quite helpful....

http://now.netapp.com/NOW/knowledge/docs/ontap/rel7311/html/ontap/rnote/rel_notes/reference/r_oc_rn_feat73_aggr-size-max-drives.html

but is lacking 450 GB disks numbers (I was hoping it would show up with the 7.3.1.1 docs but unfortunately).

Can anyone confirm the maximum number of 450 GB data disks possible in single aggregate? I'm guessing 41 (just based on division) but would like ot be sure before I go expanding an aggregate at a customer site.

Thanks.

Pretty close, the max is actually 40 x 450GB data drives per aggregate with DOT 7.3.

The 7.3 max number of 450GB drives per aggregate is 46, but a max of 40 data disks. (7.2 is 39 total and 35 data)
