Updated by Mahima Kumar on May 08, 2017

Article Overview

This article focusses on how to:

  1. Register Data Centers and SRN's within the SafeHaven Console for CenturyLink Cloud, VMware vSphere and Manual(Standalone VMware ESXi hosts and DCC) datacenter type.
  2. Pair the SRN's together to set up Protection Groups.

A single SafeHaven Cluster can have upto 64 datacenters registered within itself which can be accessed through a single pane of glass. Each production and recovery datacenter has to be registered within the SafeHaven Console.

There are 4 Data Center Types available:

  1. VMware vSphere
  2. VMware vCloud Director
  3. CenturyLink Cloud
  4. Manual (Standalone VMware ESXi hosts and DCC)

NOTE: For CenturyLink Cloud, each sub-account has to be registered as a separate datacenter.

Requirements

  1. SafeHaven Cluster already installed.
  2. CMS and SRNs to have proper network connectivity as per SAHA4.0 Networking

Assumptions

SafeHaven Cluster already installed with proper network connectivity between CMS-SRN and SRN-SRN.

  4. WAN Replication IP: SRN IP used to communicate with the peer SRN for WAN replication. Typically set as the Private IP of the SRN.
  5. Local iSCSI IP: SRN IP used to communicate with the production/recovery servers in that particular Data Center. Typically set as the Private IP of the SRN.
  6. Do not modify the Service Port (TCP) and Heartbeat Port (UDP)

NOTE: Incase SRN has multiple NIC's, Service IP and WAN Replication IP will be the Primary IP of the SRN which has proper network connectivity to other SRN's and CMS. Local iSCSI IP will be set to 0.0.0.0

Upgrade

NOTE: Follow the same procedure to register the all the SRN's within the SafeHaven Console.

Add SRN Peer
