Chapter 2 19
Disk Space Requirements
2 Disk Space Requirements
This chapter contains information on disk space requirements related to MPE/i/X Release
6.5.
The combined System Load Tape (SLT) and Fundamental Operating system (FOS) disk
space requirements shown in Table 3-1 are the minimum for any system software version.
The table shows the amount of non-contiguous disk space sectors required for the three
operating system components (SLT, FOS, SUBSYS) of the currently supported versions of
the operating system software.
During the modification process, some files are duplicated temporarily, and sometimes
older versions of files are retained temporarily. As a result, the peak amount may be
greater than the final amount. You must have the peak amount available to successfully
modify your system.
Ensure that you have enough room on LDEV1 for all the SLT files. The FOS files do not
have to go onto LDEV1.
For procedures for estimating the disk space required for your system, refer to “Estimating
Disk Space” in the System Software Maintenance Manual.
