Linux Hardware and Operating System Recommendations and Requirements

For a distributed deployment, CA Network Flow Analysis supports running the Harvester on dedicated Linux servers that meet the following system requirements:

• Red Hat Enterprise Linux 5.5 or 5.6 on a 64-bit processor
• Java Runtime Engine (JRE) 1.6u41, which is included with the ISO files from CA Technical Support.

  If the installation server does not have JRE version 1.6 installed, the installation or upgrade program fails to launch. We recommend that you install JRE 1.6u41, the version that was used in CA Network Flow Analysis 9.1.3 testing. Untested JRE versions may produce unexpected results.

• English, Chinese (Simplified), French (France), or Japanese language

  Appropriate language packs installed on all servers for localized deployments

We recommend that Linux Harvester servers meet the following specifications:

• Two 2.26-GHz quad-core processors
• 12 GB RAM
• Six 300-GB, 10,000-RPM SAS hard drives in RAID 5 configuration
• 1-Gb Ethernet port
• Root partition that contains 40 GB of available space
• Partition for CA Network Flow Analysis that contains the following amounts of available space:
  • 41 GB for the installation/upgrade files
  • 1 TB for data

If you do not have enough available space in the /tmp directory and you cannot configure it, relocate the directory. Export the IATEMPDIR environment variable (for the Install Anywhere temporary directory) to set a new location, and select a directory with sufficient space.

Notes:

• CA Network Flow Analysis 9.1.3 supports installation on servers with IPv4 addresses. Installation is not supported at this time on servers with IPv6 addresses.
• The specifications described in this section apply to both physical and virtual deployments.
