When planning Instant Messaging server system disk space, be sure to include space for operating environment software, Instant Messaging software, and for any servers not currently in your network that need to be installed to support Instant Messaging (such as LDAP). Be sure to use an external disk array. In addition, user disk space needs to be allocated. Typically, this space is determined by your site’s policy. Typical installations will require:
Approximately 300 MB of free disk space for each server or multiplexor
Approximately 5 K of disk space for each user
Additional space for the Instant Messaging archive
The archive captures instant messages and archives them in a Portal Server Search database. End users can query and retrieve these archived messages using the Search page on the Portal Server desktop.
Use Table 20–1 to determine server and multiplexor disk space sizing numbers whether archiving is enabled or disabled. The figures listed in the table were generated using a 400MHz Ultra SPARC II Processor.
