IM and IM DB Requirements
To set up the Instance Manager, you need one hardware node with CentOS 7.x installed. This hardware node should meet the following requirements.
Instance Manager Node

BackNet, FrontNet For the Instance Manager to talk to CI Endpoint node via BackNet, port 4465 should be opened. |
Before setting up the Instance Manager, please also note the following:
- Make sure that the IM node's hostname is resolved to an IP address from the IM node. This can be checked by pinging IM node's hostname from the IM node itself. If the hostname is not resolved to any IP address, add the IM node's hostname and IP address to the
/etc/hostsfile on the IM node. Otherwise, it will be impossible to install additional packages, required by the Cloud Infrastructure Automation module, on the IM node. - The Instance Manager uses the SSL security protocol to provide secure communication across your network. SSL encryption and decryption tasks, however, are often resource-intensive and may slow down the performance of the Instance Manager. If the planned workload for the Instance Manager is high enough, we recommend that you set up an SSL offload engine in your network. This can maximize the IM performance through offloading SSL encryption and decryption tasks.
To set up the Instance Manager database, you need one hardware node with CentOS 7.x version installed. This hardware node should meet the following requirements.
