New NSX Versions

VMware today announced new NSX versions

New NSX Offerings

Standard Edition: Automates IT workflows, bringing agility to the data center network and reducing network operating costs and complexity.

Advanced Edition: Standard Edition plus a fundamentally more secure data center with micro-segmentation. Helps secure the data center to the highest levels, while automating IT provisioning of security.

VCSA DNS Error Troubleshoot

Setup Bind but vCenter appliance couldn’t see it. This is how you troubleshoot that.

To resolve this issue from vCenter:

  1. Open the console to the vCenter Server Appliance and press CTRL+ALT+F3 and log in with root credentials that you mentioned during the install phase.
  2. To enable shell, run this command.

    shell.set –enabled true

  3. Enter shell with this command:


  4. Ping the DNS servers to confirm communication with this command:

    ping yourdnsfqdn

  5. Use nslookup to make sure the vCenter Server Appliance can be resolved:

    nslookup vcenterFQDN

  6. Use the nslookup command to resolve the shortname.
  7. After underlying networking issue is resolved, redeploy the vCenter Server Appliance.

My issue was that firewalld was blocking DNS and once I took it out it worked. Stop yelling I will add the rules once vCenter is installed fully.

It is recommended that once you are able to reach DNS – you should redeploy vCenter.

Hope this helped.

VMware Continuent Tungsten Replicator

I was trying to get a high level overview on the Continuent Tungsten replication and this video was pretty good which helped me understand some of its high level features.

Are you using Continuent – share you experiences!

Preview New Products in Amazon AWS

Two products are in preview mode in AWS. This is a brief post about them.

DMS – DMS stands for database migration services. This service allows you to migrate a source database to a target database by means of a replication instance. AWS also allows you to migrate to a different database by using the AWS schema generator tool to generate a new appropriate schema for the new database. The replication appliances or instances are at the heart of the conversion process where all the conversion takes place. It is available in multiple sizes and depends on your performance requirements.

Below is a list of different sizes of the replication instance available.

Some points to remember.

  1. During conversion source db is fully operational and the process is non disruptive.
  2. Any delta changes at source are also fully replicated to the target. The replication appliance takes care of this and also does compression.
  3. There are no hidden charges – you only pay for the size of replication appliance you deploy regardless of your db size.
  4. Transfer between similar databases or transfer among dissimilar databases.
  5. DMS can also be used as a disaster recovery product because of its ability to constantly replicate the changed data from source to target.

Elastic File System – AWS enters the file storage sector by introducing the elastic file system – a file storage system over NFSv4 protocol. We know that S3 provides object storage and EBS provides block storage for AWS work loads. Now EFS provides file storage allowing for easy consumption for your workloads.

Some points to remember.

  1. EFS has no base charge and is pay as you go at 0.30 cents a GB. You only pay for what you use.
  2. EFS is mounted directly to your EC2 instance and multiple EC2 instances can share a EFS mount.
  3. EFS is backed by SSD storage and there is no additional cost for performance gains.
  4. EFS in theory is advertised as unlimited growth.
  5. Multiple EC2 instances in different Availability zones in a region can access the same EFS instance.
  6. EFS instance is replicated across multiple availability zones.

Hope this gave you a pretty high level over view of what AWS has up and coming.

99% of the World’s Data…


Yes, we will have a quick chat about 99% of the world’s data. Did you know that 99% of the World’s data was created in the last three years! There is no denying that we are much more connected than we ever were and this data is only going to skyrocket once we start consuming IOT devices and applications. (Internet of things).

Scientists estimate that the total data in the world is about 350+ exabytes – Thats 350 Billion Gigabytes and growing at 23% yearly – and this is just an estimate. So should business leaders invest in big data? Absolutely! According to a Forbes research, 89% of business leaders agree that big data is the next industry disrupter and will revolutionize how decisions are made. Gartner forecasted that 2016  is a digital era where big data is going to be a big disrupter.

So are you just collecting data or are you going to do something with it? Let me know in the comments below..

Learning VMware NSX – The Book!

Learning VMware NSX, Ranjit Singh Thakurratan, eBook - 2016-01-31 23-27-52My first book about deploying and using VMware’s NSX network virtualization platform is out for pre-order. It was indeed a challenge to write a book.

I spent most of last year writing the book and its finally all set to release soon. It has been an interesting but tough journey and writing the book wasn’t easy at all!  Adding to the challenge was the fact that the publisher wanted to keep the book to less than 200 pages. That however was a blessing in disguise, more readers will be willing to read a quick 200 page book about NSX rather than a 600 page gorilla.

The book is available on Amazon and is published through Packt Publishing. The kindle version is available now with the paperback shipping in early March. 

Below are some highlights about the book,

vSphere HTML Host Client (Updated!)

**Did the original post a while back but there are new updates as picked up from virtual-alan**


  • Add a new CD/DVD drive to a new or existing VM

  • Add a new network adapter to a new or existing VM

  • Add a new hard disk to a new or existing VM

  • Create a VM from a cluster

  • Migrate compute resource of a VM to a cluster and set vMotion priority

  • Change Agent VM settings for a Host

  • View Lockdown Mode in Security Profile settings of a host

  • View Certificate information for a host

  • Add a new cluster workflow (basic)

  • Remove a cluster

If you love the improvements in the web client, or may be you are a linux shop wanting to test or play with VMware ESXi and wished you could manage your ESXi host with a web client and not with the windows c# client then we may just have a solution for you!

This is my host now (no vCenter)

VMware ESXi - localhost.localdomain 2016-01-17 13-54-51

Meet ESXi Embedded host client! This tech preview VIB will do wonders for you! Once you install this VIB (Vmware install bundle) you will get your web client up and going. Now you can’t use this to manage your vCenter so watch out there.  This is still a tech preview so don’t deploy this in production is my advise although I won’t tell if you don’t! And if you are wondering – this vib was written in HTML and Javascript.

Some of the things you can do with this fling,

  • VM operations (Power on, off, reset, suspend, etc).
  • Creating a new VM, from scratch or from OVF/OVA (limited OVA support)
  • Configuring NTP on a host
  • Displaying summaries, events, tasks and notifications/alerts
  • Providing a console to VMs
  • Configuring host networking
  • Configuring host advanced settings
  • Configuring host services

So basically everything you can do with a c# windows client. This is awesome especially for *nix users!

Below is the process to install it in your host. Do this at your own risk 🙂

  1. Download the offline bundle from here.
  2. SCP this into your standalone ESXi into a /tmp directory
  3. SSH into your host and install the VIB with the below command.

    >esxcli software vib install -v /tmp/esxui_signed.vib –force

  4. Log out and go to httpps://hostip/ui

Below is how it looks to me.

VMware ESXi - localhost.localdomain 2016-01-17 13-59-20

My opinion is this is a good progress and this feature would be great. At the end there shouldn’t really be need for a vCenter to provide a rich web interface.
