The hardware requirements for your High Availability Add-on (HAA) are different between development and production environments.
|RAM||6 GB||8 GB|
|Storage||10 GB||20 GB|
While one node is sufficient for a development environment, three or an odd number of nodes are recommended in order to utilize the clustering features likely needed for your production environment.
|Cores per Node||4||8+|
(15 GB for DR deployments)
|Storage||75 GB||150+ GB|
|Network||1 G||10+ G|
Note: Always maintain an odd number of nodes. This is required to obtain a quorum needed in failure and failover scenarios.

HAA only supports 64-bit operating systems and must be installed on a clean host with no other applications and synchronized with the same NTP server.
|RHEL/CentOS 7|| 7.0 - 7.8 (Requires at least Minimal Install configuration)|
Note: If using v7.8`, Open SSL 1.0.2 and fw config are required.
