Hardware requirements

The following hardware is required for the systems that host IBM® Lotus® Connections features.

  • At least two Intel® 64 or IA-32 based server machines

    Note: See the Hardware and software requirements topic to determine how many systems you need. A pilot installation requires fewer resources.

  • Two CPUs per server, 2.6 GHz CPU speed or higher

  • Minimum 4 GB of memory per machine

  • 80 GB of available disk space on each system after installation and configuration of the base operating system

  • Make sure the servers are connected to an IP network that can be accessed by users.


Detailed space requirements

The systems that host Lotus Connections must have the following amount of disk space:
  • The temporary directory of the operating system on which you plan to run the installer must have at least 150 MB of space.

  • The Lotus Connections installer creates a directory in the following file path of WebSphere® Application Server:
  • AIX®:

    /usr/IBM/WebSphere/LotusConnections
  • Linux®:

    /opt/IBM/WebSphere/LotusConnections
  • Windows®:

    C:\IBM\WebSphere\LotusConnections

This directory requires 110 MB of available space.

In addition, each Lotus Connections feature requires the following amounts of disk space for the initial installation:

  • Activities – 40 MB
  • Blogs – 60 MB
  • Communities – 40 MB
  • Dogear – 60 MB
  • Profiles – 40 MB
  • Home page - 40 MB


Each feature requires the following amount of disk space for content stores and other files:

Table 1. Feature space requirement details
FeatureSpace requirements
ActivitiesAt least 5 GB initially to support the content store, which holds all the files, images, and other content that activity users add to their activities. This size will increase quickly as the number of users increases and the number of files and messages that users add to their activities increases.

You can limit the size of files that are added to an activity by editing the <sizeLimits> element found in the <objectStore> element of the oa-config.xml file. See the Administration Guide for information on how to edit this element.
BlogsAt least 4.5 GB. Blogs supports the following items:
  • Index file directory – Local directory on which the full-text index that users access when they search for terms in blogs is stored. This should have at least 1 GB of space.

  • File upload directory – Directory in which Blogs stores any files that are uploaded to people's blogs. This directory must be added to a shared drive if you are setting up a network deployment. You can set a maximum file size for uploaded files per blog by editing the Max Directory Size (MB) setting in the File Upload Settings section of the Blogs Administration page. (You can access the Administration page from the Blogs site that you created if you log in using the administrative user ID and password for the site.) The default value for this setting is 4 MB. So, if you do not change the default, the maximum space you will need for the file upload directory is 4 MB times the number of blogs you are hosting. This directory should have at least 400 MB of space initially.

  • Snapshot directory – When you implement a network deployment, you must create this shared directory. This directory keeps the index files on the nodes up-to-date. It must be 3 times larger than the index file. This directory should have at least 3 GB of space.
CommunitiesAt least 75 MB to support the index file directory, which stores the full-text index that users access when they search Communities.
DogearAt least 600 MB. Dogear supports the following items:
  • Index file directory – Stores the full-text index that users access when they search for terms in bookmark titles and descriptions. This directory should have at least 450 MB of space. This number is an estimate based on an implementation that uses 150 MB for a full text index of 250,000 bookmarks. The space available must be 3 times larger than the index file.

  • Favicons file location – Stores the icons that are displayed on bookmarks to help identify them. This directory must have at least 150 MB of space for a deployment with 250,000 bookmarks.
ProfilesAt least 300 MB. Profiles supports the following items:
  • Index file directory – Stores the full-text index that users access when they search for text strings in people's profiles. This directory should have at least 270 MB of space.

  • Cache file – Caches data that is accessed often. This file requires at least 30 MB of space.
Home pageAt least 100 MB. When global search and indexing are enabled, the amount of disk space required increases.

Note: The sizes of these directories, especially those that store indexes and objects, will grow as the number of users increases. Take steps to optimize the full text indexes that you use and to monitor the space availability, so that you will know when an increase in capacity is needed. See the Administration section of the Lotus Connections information center for more information.
