Maximum device size for ASE 12.5 and ASE 15.0

Up to ASE 12.5.x the maximum device size is 32GB (provided
that the OS knows how to handle large [>2GB] files) because
of the way the device number is encoded in the sysdevices
table (i.e. only 24 bits are available to describe the file
itself).

In ASE 15 this limit has been lifted.


ASE-15 device and database limits per server are as follow:

- device size limit: 4 terabytes per device
- server limit: 2 billion logical devices per server
- database size limit: 32 terabytes per database
- server limit: 32767 databases per server

So, maximum storage per ASE server is over one million terabytes (32TB x
32767).
