Thought you bought a large enough disk, probably not. Below are the actual disk sizes you get when you buy a disk from Netapp:


Raw GB Type Rightsize GB Available blocks
72 FCAL 68 139,264,000
144 FCAL 136 278,528,000
300 FCAL 272 557,056,000
250 SATA 212 432,901,760
320 SATA 274 561,971,200
500 SATA 423 866,531,584
750 SATA 635 1,301,618,176
1000 SATA 847 1,735,794,176
144 SAS 136 278,528,000
300 SAS 272 557,056,000

Keep these numbers in mind when creating new aggregates. These numbers are without the 10% WAFL overhead just by creating an aggregate or volume, as well as the default 20% snap reserve for volumes, and 5% snap reserve for aggregates.


The 5% snap reserve on aggregates will only be used when you have a Metro Cluster setup, so if you don't have a metro cluster setup disable this reservation to free up some space.


The "16TB" max limitation is there and includes the parity disks. You can use the RawSize KB vs 17,179,869,184 KB to make your volume size calculations.
