Note: in case you are going to use APS Booster, the node hosting master database needs extra 256 GB of free disk space for storing WAL files (16384 WAL files * 16 MB each).

Disk Partitioning

Array 1:

  • / - 5 GB

- for OS

  • 2 x RAM size (16 GB)

- swap

  • /usr – at least 20 GB

- for software

  • /var - remaining space

- for CloudBlue Commerce system database

NICs

BackNet

Note: Bandwidth of at least 10 Gbps is required.

Important: Due to the security reasons, disable IPv6 support in backnet network interface properties on the CloudBlue Commerce management node, UI and branding nodes.
If you use a Virtuozzo container for deploying CloudBlue Commerce management node, UI or branding node, open the container configuration file - /etc/sysconfig/vz-scripts/<container_id>.conf - and remove the IPv6 support for the host-only interface. If you create a new container, make sure that IPv6 support for backnet network interface is not specified in the container creation parameters.
If CloudBlue Commerce management node, UI or branding node is deployed on a real physical server, disable the IPv6 support in backnet network interface using the standard functionality of the OS being installed. For instructions on how to do it, refer to the appropriate documentation of the server OS.
