Cisco HyperFlex Cluster Replication

The Cisco HyperFlex HX Data Platform supports replication of virtual machines or groups of virtual machines to other clusters across a WAN for disaster recovery purposes. The data platform optimizes data transfer using change-block tracking and compression to reduce network impact. Native replication and snapshots built into the HX Data Platform dramatically reduce recovery time objective (RTO) and recovery point objective (RPO) metrics and achieve an RTO of less than 15 minutes for applications and data.

In this post we will learn how to create the replication of virtual machine between two Cisco HyperFlex HX Data Platform.

Cisco HyperFlex HX A: hx-cluster-a
Cisco HyperFlex HX B: hx-cluster-b

First login into Cisco HyperFlex Cluster A/B, go to “Replication” and configure the replication network on each HyperFlex cluster.

Input the IP configuration, click Configure.

After the replication network of both HyperFlex Cluster is ready, go to Datastores and click “Create Datastore” to create the target Datastore on Cisco HyperFlex Cluster b.

Then go to Cisco HyperFlex Cluster a and choose Replication, click “Create Replication Pair“. Input the Replication Pair Name, then Next.

In the Remote Connection window, enter Management IP, User Name and Password of remote cluster, then Pair.

In the Datastore Mapping window, select the remote datastore on the Remote Datastore menu and click Next.

In the Summary window, click Map Datastores.

Create the Protection Groups, input “Protection Group Name” and select “Protect virtual machines in this group every“, click “Create Protection Group“.

Now we can start the replication of virutal machine. Go to Virtual Machines and select VM-A virtual machine which is Unprotected. Click Protect.

Add the VM to an existing protection group. Click Protect Virtual Machine. Now it shows that the VM is now protected.

  1. Hi Victor
    Thank you for your post.
    My name is Neo. I have a question. After I did the replication settings, but I want to modify the ip configruation, but they are gray I can’t modify it. Do you know how to modify them?
    Thank you


  2. If i want to change the replication factor from RF2 to RF3 in existing HX infra by adding 2 more nodes, does that impact on the entire HX infra & rebuild is require or just the storage part will impact? And how much downtime that will needed say for 2 TB data.
