The HP-UX operating system has undergone significant changes since its inception. These changes have generally improved system reliability and increased its capabilities with respect to I/O in order to keep pace with changes in storage technology. For example, in HP-UX 9.0x the largest disks that could be handled by the native OS were 4GB. In HP-UX 10.20 this has been increased by orders of magnitude.
