The total number of snapshots is dependent on the LVM, but 255 is a safe
number. There are, however, definite limitations as to the number of ACTIVE
snapshots:

32bit system:
- 10 per LV
- 20 per system

64bit system:
- 1 per LV
- 10 per system

This and other information about Snapshots is located on our Knowledge Base from link below in section of "What is the maximum number of snapshots?".
