What is the Tandem file system?
Tandem, like many Linux and Unix flavors, treats disk files, devices like terminals, printers, tape drives, and processes, as files. Disk files can be either SQL files or Enscribe files. You can use NonStop SQL to access the former type and Enscribe database record manager to access the later type of files. Enscribe files can further be key-sequenced, entry-sequenced, relative or unstructured files. The file system allows you to open devices and processes as files and do the communication. Besides, the usable space on the disk is called volume and the volume can be assumed to be divided into subvolumes, which in turn store the files. There is no concept of subvolume within a subvolume.
