Reference Specification

The HA deployment is only applicable to an environment within one data center, aiming to prevent the single point of failure (SPOF) on applications, virtual or physical machines. For customized deployments, please contact NetBrain Support Team for assistance.

Notes:
1) The required hard disk space must be exclusively reserved for NetBrain. For better performance, MongoDB Server is recommended to be installed on a machine equipped with Solid State Drive (SSD), or Hard Disk Drive (HDD) RAID-10.
2) Each Front Server is recommended to manage 5,000 network nodes at most.
3) The sentinel node of Cache Server Cluster can be installed on any one of Worker Servers.
