Required entities
The replication uses the following entities, defined one on top of the other:
- Ethernet ports - every InfiniBox system includes 3 controller nodes. Every node has access to all drives. Depending on the available InfiniBox model, one may have either 2 (F61xx/F21xx) or 4 (F62xx/F22xx) 10Gbps Ethernet ports per node.
- Network space - different InfiniBox services require a network space of their own.
- The same network space serves both Asynchronous and Synchronous replicas
- Separate network spaces are required for Replication and for NAS.
- Service - an InfiniBox feature that requires network connectivity. For example: Replication, NAS.
Required ports
Please consult the InfiniBox Best Practices Guide for Setting Up the Replication Service.
Creating ports
Create a port on each of the Nodes:
On Node 1:
config.ethernet.interface.create_single_port port=N1ETH1
On Node 2:
config.ethernet.interface.create_single_port port=N2ETH1
On Node 3:
config.ethernet.interface.create_single_port port=N3ETH1
Create a network interface
- See detailed instructions here: Creating a network interface
Create a network space
- See detailed instructions here: Creating a network space
Creating a link
- The link verifies that there are enough IP addresses on both systems (1 for Management, 3 for Synchronous replication, 3 for Asynchronous replication, as explained above)
- For a description of Link States, see: Detaching and attaching a link
- See detailed instructions here: Creating a link
Creating a replica
- For detailed instructions and volume prerequisites, see here:
