Replication

Configuring Replication

To configure replication on a HyperFlex Controller VM in a Stretch Cluster, you complete the necessary VLAN configuration on the fabric interconnects using UCS Manager manually. Ensure to use the same VLAN configuration on the UCSM fabric interconnects, on both the sites in a Stretch Cluster.


Attention

For configuring the replication network in a Stretch Cluster deployment, see the Cisco HyperFlex Administration Guide for your release.

Configuring Replication VLAN in Cisco UCS Manager

To configure the replication VLAN using UCS Manager, complete the following steps in Site-A and Site-B:

  1. Create a replication VLAN.

  2. Associate the replication VLAN to the HX service profile of the HyperFlex cluster.

Creating Replication VLAN


Attention

It is best practice to delete unnecessary and stale VLANs. If the VLANs already exist on your fabric interconnect, you do not have to recreate it.

Create the following replication VLANs, if you do not see them in your HyperFlex cluster. Strictly follow the naming conventions that are specified in the table.

VLAN ID

Specify Name

Name Displayed in UCSM

<VLAN ID>

<hx-inband-repl-VLAN ID>

hx-inband-repl-VLAN ID (VLAN ID)

Procedure

Step 1

Log into Cisco UCS Manager. In the Navigation pane, click LAN.

Step 2

On the LAN tab, right-click VLANs and click Create VLANs.

Step 3

In the Create VLANs dialog box, complete the following fields for all the VLANs that must be supported on the fabric interconnect:
