Posted on by

In first part of this series vSphere Replication Introduction we have discussed what is vSphere Replication and how it works. We also discussed the architecture and components involved and saw the possible use cases where vSphere Replication can be used.

In this post we will look on how to setup lab for deployment of vSphere Replication and what pieces of infrastructure should be ready before we start using vSphere Replication.

I am going to use cross site replication in my lab so here is my lab components:

Hardware Component

I have a Dell M4800 Mobile workstation laptop with 32 GB of RAM and i7 Quad Core processor. I am running all the lab components inside VMware Workstation.

My Lab Components

  1. I installed Server 2012 R2 Datacenter edition as my base OS. This machine will act as my Domain Controller as well as DNS Server (AD Integrated DNS).
  2. I have another Server 2012 R2 Datacenter edition installed in VMware Workstation.

vSphere Replication-Part 1: Introduction

Posted on by

I am quite a new candidate to vSphere Replication and have seen quite a few appliances deployed in our production environment as we are offering Disaster Recovery to Cloud (DR2C) services to our customers in vCloud Air and often have to troubleshoot issues related to replication.

So to understand how disaster recovery works and what should be the area we should be looking for while troubleshooting replication issues, I decided to try my hand on learning and deploying vSphere Replication in my lab.

So let’s begin with understanding what is vSphere Replication and its architecture and what components are involved in setting up disaster recovery environment.

What is vSphere Replication?

Earlier vSphere Replication was a feature of Site Recovery Manager (SRM) that automates the failover of virtual machines to a recovery site. vSphere Replication enables the replication of virtual machines (VMs) at the virtual layer instead of at the storage layer, as was required with earlier versions of vSphere and SRM.… Read More

In last post of this series we learnt how to install VUM and discussed why we need VUM and how it can simplify the update and upgrades in a large infrastructure and thus make life of a VMware admin easy.

In this post we will see how to configure various settings in VUM and how to create baselines and attach the baselines to host/cluster and then how to remediate hosts.

In last post of this series we have seen how to add Esxi hosts to domain and how to configure Esxi host to reach iSCSI storage.

In this post we will learn how to install and configure vSphere Update Manager.

Why you need VUM?

You can ask this question to yourself that do you really need VUM in your environment especially while working in Lab environment. I would say yes. May be you are not looking for any upgrade related tasks in your lab but it is always a good idea to have hands on how VUM operates.… Read More

vSphere-6:Part 8-Configuring Esxi Hosts Settings

In last post of this series we have seen how to create and configure  dvswitch and portgroups on dvswitch and how to migrate networking from Standard switch to dvSwitch.

In this post we will see how to configure basic esxi host settings.

6: vCenter Server 6 Basic Configuration

7: Configuring dvSwitch & Port groups

Let’s get started with some basic configuration tasks on the Esxi host.

Adding Esxi hosts to Domain

It’s always a good idea to add Esxi hosts to your corporate domain. Adding Esxi hosts to domain allow you to push specific configurations and security settings from your Domain Controller. Also it can help you track which user has done what activity on esxi hosts (in case Esxi host is disconnected from vCenter and user needs to connect to host directly)

Connect to vCenter server Web-Client and select the Esxi host.  … Read More

Performance Charts service returned an invalid response

Posted on by

Today while working in my lab I was facing performance issues with one of my Esxi host and decided to analyze the performance chart of the host to find out the root cause.

When I select the host and clicked on Performance tab, there was nothing in there and instead it returned an error “Performance Charts service returned an invalid response“

However when I switched to advance view I was able to see the charts.

This was strange. I started googling with the error message and came to a discussion thread on VMTN where someone has suggested to enable IPv6 on host.

I followed the same thing and enabled IPv6 on my Esxi host and rebooted it for changes to take affect. Once host was rebooted I again selected the performance charts and still I was seeing the same error.

I continued with googling and came to a cool Blog-Post by MATT BRADFORD and followed the steps.… Read More

Using Template Host for Consistent Network Configuration in dvSwitch

Yesterday while configuring dvSwitch and Port groups I came across a new cool feature in vSphere 6 and I was amazed to see this. I will talk about this feature in this post and will demonstrate how to use it.

Let’s see what this feature is all about.

In my last post Configuring dvSwitch and Port Groups I demonstrated how to add Esxi hosts to dvSwitch and migrate virtual networking from Standard switch to dvSwitch. If you remember I have added only one host at beginning as I am not very much comfortable with dvSwitch at the moment.

Once it was successfully added I was trying to add the remaining 2 hosts to dvSwitch and during doing so, discovered a new feature which I have not seen earlier. Let me give a little bit background of this feature.

In vSphere 6 there is a feature of using template host in dvSwitch.… Read More

In last post of this series we have seen how to configure and install licenses for vCenter Server and Esxi hosts. Also we have performed some basic tasks like creating Datacenter/Cluster and adding hosts to cluster.

In this post we will see how to configure networking in vCenter Server.

6: vCenter Server 6 Basic Configuration

This post will be revolving around dvSwitch and associated components so that we can take benefits of some advanced features provided by dvSwitch.

If you are a newbie to VMware then I would recommend going with standard switches in beginning and playing around options to gain clarity on how virtual networking works and what are the differences between while working with physical networks and then with virtual networks in VMware vSphere.… Read More

In last 2 post of this series we learnt how to install vCenter Server 6 on Server 2012 and how to enable AD authentication for SSO so that your domain users can login to vCenter server and manage it.

5: Enabling AD Authentication for vCenter Server

In this post we will touch down on basic tasks that needs to configure vCenter before we can start using it in Lab/Production. Steps included in this post are typically for Lab environment and you might need to perform some additional tasks before your prod vCenter goes live.

Let’s talk less in this post and dive directly into configuring vCenter server.

1: Configuring Licenses for vCenter and Esxi hosts

Installing vCenter Server and Esxi host license is something which I love to do as soon as I complete installation process.… Read More

vSphere-6:Part 5-Adding AD Authentication in vCenter Server

Posted on by

In last post of this series we learnt how to install vCenter Server 6 on Server 2012. I am new to vSphere 6 so at beginning I had kept things simple and installed vCenter and PSC on a single machine (embedded mode) and also used embedded vPostgres database.

If you have missed earlier posts of this series then you can access the same by clicking on below links:

1: Introduction to vSphere 6

2: vSphere 6-Lab Setup

3: Installing and Configuring Esxi Server 6

4: Installing vCenter 6

Earlier vCenter Server was holding the SSO component, but in vSphere 6 it is included as part of PSC. The Platform Services Controller contains the shared services that support vCenter Server and vCenter Server components.

In this post we will learn how to configure AD authentication in vCenter Server 6.0.

The vCenter SSO authentication service makes the VMware infrastructure more secure by allowing the various vSphere software components to communicate with each other through a secure token exchange mechanism, instead of requiring each component to
authenticate a user separately with a directory service like Active Directory.… Read More
