Hardware prerequisites

Check the hardware that you need for IBM® Content Collector, for the source systems that contain the documents to be archived, and for the repositories in which you want to archive the documents.

For the most current hardware requirements, see the System Requirements technote on
Prerequisites for IBM Content Collector 4.0.1 (https://www.ibm.com/support/pages/node/614445).

In addition, consider the following requirements:

  • You need a distinct computer or virtual machine that runs on one of the supported Windows operating systems. This computer or logical machine must be connected by a TCP/IP network to the servers on which your repositories and your source systems are installed.

    For Microsoft Exchange, this computer must be in the same domain as the Microsoft Exchange server. Microsoft Outlook must also be installed.

  • Content Collector uses a multiple process architecture which supports to use multiple GB of main memory efficiently. In addition, performance is greatly improved if there is a sufficient amount of memory available for the operating system disk cache.
    The minimum requirement of 4 GB of memory is sufficient for Content Collector servers that are used for basic document collection and archiving. However more memory (the recommended amount is 8 GB) is required:
    • For production servers that are intended for large workloads, in other words, for servers that process many, potentially large documents in parallel
    • For Content Collector servers that also provide search, viewing, and restore services through web applications, for example, in mailbox management scenarios
    • For the servers that run the SMTP Receiver component of the SMTP Connector
    More than 4 GB can efficiently be addressed on systems using a 64-bit version of the operating system.
  • Working directories, like the directory that the Email Connector uses to create and store temporary files or the seedlist directory of the IBM Connections Connector, must be on a separate and fast disk.
  • Use a Raid 5 array for your operating system and for the Content Collector components. Raid 5 array helps avoid system downtime in the case of hard-disk failures. However, do not use a Raid 5 array for the working directory of the email server connector because of the write penalty of Raid 5.
