Portal comes bundled with a pre-compiled Python 3.8 which is installed under /opt/cantemo/python
OS requirements overview¶
Portal is a easy to install product, currently we support the following OS :
Red Hat 7.7 64-bit or later 7.x version
Red Hat 8.3 64-bit or later 8.x version
CentOS 7.7 64-bit or later 7.x version
CentOS 8.3 64-bit or later 8.x version
Portal is flexible in that its main requirements closely match the requirements of most modern operating systems, therefore allowing for a wide range of hardware that it could potentially be hosted on. As it is a web service it benefits from the same kind of hardware that web services run well on, namely memory and I/O.
It is difficult to specify exactly what hardware will be sufficient, but sizing will depend on especially the following parameters:
Amount of transcoding peak time
Activity of users (amount and complexity of searches)
Please consider the following when building a portal server.
Please talk to your local vendor when designing CPU.
Compare CPU’s performance here:
Always separate Mediafiles from the SQL-database and logs. Media transfers may “starve” your SQL-database. Use SSD disks in a RAID1 mirror for your SQL-database if you have more than 250.000 items.
Never put your SQL-database or your searchindex on a SAN. Never put your SQL-database or your searchindex on the same underlying spindles as your hires or lowres media.
24 GB is minimum for production environments, but developemnt and demo systems may run at only 10 GB RAM. We recommend 32-64 GB of RAM for small systems, depending on amount of items and size of metadata schemas.
The transcoder can make use of a graphics card to accelerate RED transcoding. This is required for production deployments because of performance, but for Demo and PoC installations it is possible to run in software only mode.
The requirements for the graphics card are as follows:
Graphics card with OpenCL 1.1 support in Linux 64-bit
>= 768 MB of RAM (recommended 2-4 GB or more)
An example of a low-end card which is supported is NVIDIA GTX 660.
The following application can be used to check the graphics card compatibility:
Portal has no restrictions on being deployed on a true cloud environment such as Amazon EC2, Google Cloud or Rackspace Cloud. The I/O requirements for Media Asset Management solutions can be heavy so please keep that in mind when choosing an environment, and that we expect a unmodified kernel.
VPS hosts typically run modified kernels which can further impact performance, or even the abilities of the system.
Portal does not need any specific filesystem and is compatible with any filesystem that can be mounted on the server. However we would like to outline some features and limitations on common used filesystems.
Portal requires Postgresql Version 10 or greater. The default installer comes bundled with Postgresql 10.13.
