Supported platforms

Estimated hardware requirements

These hardware requirements are estimated, and are expected to vary significantly with queries per second and collection size. Please contact support@funnelback.com if you need a more accurate assessment of your individual hardware requirements.

Funnelback recommends that production search environments consist of a minimum 2-server architecture:

  • Dedicated gathering/filtering/indexing/administration server

  • Dedicated query processing server

Additional query processors can be added as query load increases, or if additional redundancy is required.

Small website / intranet

  • 10K documents

  • Predominantly HTML content, some binary files (averaging 1MB each)

Knowledge Graph

The Knowledge Graph service uses additional memory above Funnelback’s normal memory requirements, either on the Funnelback server itself or on a separate graph database server if preferred.

The amount of memory required will scale with the amount of data stored in the knowledge graph (e.g. number of nodes * average amount of metadata per node). At this time we do not have enough large scale datapoints to provide useful estimates.

Supported operating systems

Funnelback is tested and fully supported on the following operating systems:

  • Red Hat Enterprise Linux 7 (64 bit) or CentOS 7 (64 bit)

  • Microsoft Windows Server 2012 (64 bit)

  • Microsoft Windows Server 2016 (64 bit)

User permissions

Windows

  • The user for scheduling tasks as well as any user that runs command line scripts must have the SeCreateSymbolicLinkPrivilege permission.

Supported web servers

Funnelback ships with an embedded webserver (Jetty) which is used to serve all web pages. The use of another web server for administration and Funnelback’s modern search UI is not supported.

Required server software

Common

Linux

  • libstdc++ - Normally installed by default, or with yum install libstdc++

  • crontab - Normally installed by default, or with yum install cronie

  • GLIBC 2.4 or greater

  • Some fonts - e.g. yum install dejavu-fonts-common dejavu-sans-fonts dejavu-sans-mono-fonts dejavu-serif-fonts dejavu-lgc-sans-mono-fonts urw-fonts.noarch

Windows

None other than for gathering specific enterprise systems.

Required client software

Administration interface

  • For the best user experience, we recommend the latest Chrome, Firefox or another evergreen browser with JavaScript enabled when using the Funnelback web administration interface.

Public interface

  • Funnelback search interface browser requirements are generally dictated by the specific search template file in use, however please note SSLv3 is not supported, preventing Internet Explorer 6 and earlier from accessing Funnelback services over HTTPS.

  • Several client-side features implemented by the default Public Interface and associated Javascript libraries may not operate correctly (if at all) on certain browser / operating system combinations:
