The grid engine software directory tree has the following fixed disk space requirements:
40 Mbytes for the installation files without any binaries
Between 10 and 15 Mbytes for each set of binaries
The ideal disk space for grid engine system spool directories is as follows:
10-200 Mbytes for the master host spool directories
10-200 Mbytes for the Berkeley DB spool directories
The spool directories of the master host and of the execution hosts are configurable and need not reside under the default location, sge-root.
You must satisfy several Windows-specific prerequisites before you can install N1 Grid Engine on hosts that are running the Windows operating system. You might need to install additional software on your computer which might require additional disk space. See Appendix A, Microsoft Services For UNIX
