vCloud Availability for vCloud Director-Part-1-Introduction

By | 09/09/2018

What is vCloud Availability for vCloud Director (VCAV) ?

vCloud Availability for vCloud Director is a Disaster Recovery-as-a-Service (DRaaS) solution that provides simple and secure asynchronous replication and failover for vSphere managed workloads.

VMware released vCloud Availability for vCloud Director keeping in mind to provide cloud innovations to vCloud Air Network partners so that they can implement this software solution to provide Disaster Recovery as a Service (DRaaS) to customers.

Customer’s who are using vCloud Air, knows that vCloud Air uses vSphere Replication to provide the DRaaS service to their customers. This is a very similar solution which vCAN partners will now be using for DRaaS.  read more

Locating HCX System ID

By | 07/07/2018

HCX System ID is needed when you are working with VMware support team regarding any HCX issues. 

HCX system id can be found via CLI as well as GUI. We will discuss both methods in this post.

CLI Method (You can only find on-prem HCX system id using this method)

Connect to the on-prem HCX ENT appliance via console or SSH using admin credentials and run command: cat /common/location

[admin@hcx-ent ~]$ cat /common/location

Cleanup HCX Deployment

By | 05/07/2018

In this post we will learn about how to do cleanup of a HCX deployment in a right way. 

Below are the high level steps for HCX cleanup.

1: Unstretch a Layer 2 Network : Unstretching a Layer 2 network is necessary before removing the associated L2C appliance. Steps given below

  • Login to vCenter Web Client and click on HCX plugin and navigate to Interconnect > Extended Networks tab.
  • Select the network you want to remove and click the X button and hit OK to confirm.

2: Delete the L2C virtual appliance: To delete the L2C appliance, go to interconnects > HCX Components > Network Extension Service tab and select the appliance and click on Remove.

Site pairing task is straight forward and it should compelte without any issue if all your configuration is correct. However In my lab I was getting an error “untrusted ssl connection” when trying to do site pairing. read more

HCX Site Pairing failed with error “Untrusted SSL Connection”

By | 29/06/2018

In last post of HCX series, we deployed HCX Cloud appliance and performed basic configuration. The next step was to pair the HCX Enterprise appliance to the HCX Cloud so that we can start consuming HCX features. 

When I tried pairing the on-prem HCX to HCX Cloud, I was getting ssl connection error and site pairing task was failing.

I was pretty sure that this is happening because of untrusted ssl certs in my lab and I was thinking that may be I need to replace the self-signed certs with the CA signed certs.  read more

Learning HCX-Part 3-HCX Cloud Deployment & Configuration

By | 28/06/2018

In last post of this series, we deployed the HCX Enterprise appliance in on-premise and connected it to vCenter server, NSX manager and PSC. In this post we will deploy HCX cloud appliance in cloud side and will walkthrough basic configuration steps.

As of now, I don’t have a true cloud site but I have 2 vCenter servers in 2 location. Site A is where I deployed HCX Enterprise and Site B is where I am deploying HCX Cloud applaince. I am treating my Site B as cloud location for now.

HCX Cloud deployment is very much similar to HCX Enterprise deployment. Below slideshow walkt hrough the deployment steps. read more

By | 28/06/2018

In first post of this series, we learnt about basics of HCX and we discussed that HCX is available in 2 versions i.e HCX Enterprise (for On-Prem) and HCX Cloud (for cloud providers).

In this post we will learn how to deploy HCX Enterprise appliance in on-prem and we will touch down on basic configuration. 

Deployment of HCX Enterprise appliance is very much similar to a standard ovf deployment of any VMware product and nothing fancy is there. Below slide show walk-through steps of deploying the appliance.  read more
