Yes. Do you really need more inodes than 1 per 4 K? That would mean a LOT of really small files.
4 K is the minimum size of any file in WAFL (the write anywhere file layout) that Data OnTap uses. For files are under 4K, the inode informaiton is written in the 4K data block with the data.

Actually WAFL uses a trick where files 64 bytes or less have their data stored in the inode itself and no data block is used at all. This is very handy for symbolic links, which are often short enough to not require a 4K data block.
On a NFS client, 'du -k' shows 0K used by a 64 byte file and 4K used by a 65 byte file.
