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
