Hardware and Software Requirements

Hardware Requirements

The hardware requirements for your High Availability Add-on (HAA) are different between development and production environments.

Development Environments

ItemMinimum RequirementsRecommended
HAA Nodes13+
Storage10 GB20 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.

Production Environments

ItemMinimum RequirementsRecommended
HAA Nodes33+
Cores per Node48+
(15 GB for DR deployments)
30+ GB
Storage75 GB150+ GB
Network1 G10+ G

Note: Always maintain an odd number of nodes. This is required to obtain a quorum needed in failure and failover scenarios.
