This is probably an attempt to 'short-stroke' a larger disk with the
intention utilising only a small ammount of the disk surface, as a
technique it used to be quite common for certain apps (notably DBs).
Hence you saw deployments of quite large disks but with perhaps only
1/4-1/2 physical utilisation.
As the industry has moved toward HW RAID, its less prevalent, but
still has some merits on occassion.

The above command creates vxfs file system on first 2048000
blocks (each block size is 1024 bytes) of /dev/rdsk/c5t20d9s2 .
Like this is there a option to limit the size of ZFS file system.? if
so what it is ? how it is ?
No, there's nothing similar.
Space is managed at a pool level. Writes by any filesystem may occur
anywhere in the pool.
Can I ask why this would be useful to you? What can you accomplish by
limiting the filesystem to a particular location? There might be
alternatives.
