## Prerequisites

- All servers in a muliti server deployment must share the same user and group IDs
- A license file required per a CORE server. By a CORE server we mean the server where the CORE services is enabled. So if you have two recording clusters with a replay server then you require 3 license files.

- DNS, NTP and SMTP on all servers should be configured same. For that check the following files:

  Configuration | Location
  --- | ---
  DNS | /etc/resolv.conf /etc/hosts
  Time/NTP | /etc/ntp.conf
  SMTP | /etc/postfix/main.cf

- Autostart of the following services should be enabled:
  nfs, netfs, ntpd, postgreSQL, postfix
- On Virtual machines ensure that VMWare tools are installed and running on all servers of the cluster

There are two types of multi server deployment:

- Cluster Configuration
- High Availibilty Configuration
