Hitachi Global Link Manager Software Installation and Configuration Guide

If you want to specify different drives as the installation location of Global
Link Manager and the storage location of the database files, the following
free space is required:
Disk on which Global Link Manager is to be installed: 1.5 GB or more
Disk on which the database files are to be stored: 4 GB or more
The guidelines for the maximum number of hosts, multipath LUs, and paths
that can be managed are described in the following table.
Table 1-3 Guide to maximum numbers for Global Link Manager

For the maximum numbers of multipath LUs and paths per host, use the
following formula:
Maximum-number-of-multipath-LUs-or-paths / Number-of-management-
target-hosts
#2
If DMP or HP-UX multipathing is used on the host, you also need to take
into account the maximum number allowed when using multipath
management software.
#3
If acquisition of path availability information (path status log) for the host
is enabled to output reports on path availability information, set
approximately 1000 for the maximum number of paths per host on which
HDLM version 5.9 or later is running.
By default, acquisition of path availability information (path status log) is
disabled. To enable or disable the acquisition, use the
server.pathreport.enable property in the property file
(server.properties). For details on how to set the property file, see
Changing Global Link Manager Environment Settings on page 3-23.
For details on how to output reports on path availability information, see
Help.
The following table lists the maximum numbers of paths and multipath LUs
per host when using DMP or HP-UX multipathing.
