They can officially grow to 16 x 24 (aggr size per node x supported nodes in a cluster). I believe you can have multiple aggregate members on the same filer so in theory you could have 25 16TB aggrs on a 6070c x 12 (cluster limit) to make a single striped volume of ~4.8PB. In theory.....
Good luck backing that up though.

You could try GX...
I have 17.3TB and a 20.73TB volumes (after Formatting, after WAFL...i.e. USEABLE)
Not sure (yet) how large these can grow, but they are striped aggregates across two heads (soon to be four!).

In my opinion (as a 12-year customer), the 16TB limit is the number one deficiency in NetApp software at the moment, and perhaps their biggest deficiency ever. I would be very surprised if they weren't losing customers over this issue.

pretty wasteful if you're trying to maximize your aggregate size. 3
shelves would
give you 2 aggregates but you'd need 4 raid groups (8 drives gone to
parity).
I hope NetApp will raise the max raw aggregate size soon. I

I am running GX but the vol/aggr code is supposed to be the same.
I have 26 disks of 750 per head. I played at the beginning and think I was limited to 21 or 22 disks in
an aggregate.
It did take the better part of the day to re-zero the disks again
They right size to I think 632gb

We're going to buy some shelves of 750G ATA drives. An aggregate is limited to 16T "raw" (which I presume includes parity disks). Not having any 750G drives yet, we don't know what they size down to. Can anyone tell us how many 750G disks (including parity) that you can stuff into an aggregate?
