3 Disk Space Requirements
This chapter contains information on disk space requirements related to MPE/i/X Express Release 65.02.
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.
