I have recently read a new eBook on Hyper-V Replica named “Hyper-V Replica Essentials”, written by Vangel Krstevski. Vangel Krstevski is an IT prodigy, excelling in virtualization and network design. He is an expert in virtualization deployment and management.
So the book is a small edition about 100 Pages, on how to create the replication between Hyper-v Servers. But there is also some cluster explanation, on file sharing and SMB. for starting with Hyper-v replica this is a great book to start with.
It is an easy to read book with all step by step instructions on how to install the base components for a Hyper-V Replica environment.
The covered Chapters are :
- Introducing Hyper-V Replica.
- Installing Failover Clustering with Server 2012 shared storage functionality ( File Storage / SMB )
- Configuring Hyper-V Replica.
- Authentication Hyper-V Replica. ( nice SSL samples )
- Administering Hyper-V Replica.
What I liked the most of this book is that not only the basics are covered but also the Hyper-v Replica Certificated based. Most books are skipping this, but here it shown in a nice step by step detail.
For those of you who would like to get started with Hyper-V 2012 Replica, I recommend reading this book. You can get your hands on a copy of the eBook (PDF, Kindle etc.) by going to Packt Publishing website: Hyper-V Replica Essentials
Some Copy from the Packt Website :
Enterprises need to make sure that their systems are always up and running no matter what happens. Hyper-V Replica is a free disaster recovery tool in Hyper-V 3.0 that creates and maintains copies of virtual machines (VMs). In the event of a catastrophic loss, an administrator can failover to the replica VMs and provide business continuity.
Hyper-V Replica Essentials is a step by step guide to configuring Hyper-V Replica in various deployment scenarios. This book will give you an overview of Hyper-V Replica before taking you through the prerequisites required to properly configure Hyper-V Replica. Then, through a series of practical steps, this book will enable you to take advantage of this highly beneficial disaster recovery tool.
Hyper-V Replica Essentials starts by introducing you to Hyper-V Replica and will help you understand what it does and where you can apply it. We will then move onto learning how to configure a server environment with failover capabilities based on Microsoft Hyper-V and also how to use features including Live Storage Migration. Finally, you learn how to configure Hyper-V Replica authentication, and to troubleshoot problems with Hyper-V Replica as well as solving different types of problems.
A fast-paced, step-by-step guide to configuring Hyper-V Replica in various deployment scenarios.
Who this book is for
Hyper-V Replica Essentials is for Windows Server administrators who want to improve their system availability and speed up disaster recovery. You will need experience in Hyper-V deployment because Hyper-V Replica is built in the Hyper-V platform.
With Windows 2012 the clustering changed. the basic config san connected to the cluster is no longer the best option. using the Scale out file server you get better performance and better redundancy. but more important the cost are less. below are some screen shots from the TEE13 sessions more about this is coming this week.
The session links are also there. Check it out. Windows 2012 R2 is changing your IT designs.
My Birthday gift would be http://www.violin-memory.com/products/velocity-pcie-cards/
This is the way to bypass your san and get an optimized Windows 2012 environment to boost your performance
With the new products that are available end of 2013 ( Windows 2012R2 and the system center R2 ) releases Replication will be important all the way and will be easier to create but also the environment will be more complex. Replication on kerberos is easy to uses even shared nothing is quick and fast but what about certificate based ?
Easy to use click a certificate and use it. It is that easy or not ? well it is almost.
In this case I have My DC that hold a Enterprise Root CA and two clusters and 4 VMM servers,
Well You will only need the Root CA and Two Hyper-v server Clustered in different clusters.
yes we will do Clustered Based Certificate Based Replication ( CBCBR )
Open Certification Authority (certsrv.msc) from Administrative Tools
Right click on Certificate Template and click on Manage then we duplicate the Workstation Authentication template
Give the Certificate a nice name like Hyper-v Replica Authentication
That you know where the certificate is for.
There are a few things we need to change or can change
I choose for 2012 usage only in the compatible settings Certificate recipient and authority can be set to Windows Server 2012
The Security settings Ensure that Authenticated Users are allowed to Read and Enroll.
Edit Application Policies and add Server Authentication
Subject Name Change the option to Supply in the Request
Now that the Certificate template is ready we are going to import this certificate
Open Certification Authority on the server and click on Certificate Templates
Select Action and choose the New option followed by Certificate Template to Issue.
Choose the certificate template name from the pop-up box
Now that the basic is ready on our DC we can deploy the Certificate to the clusters / hyper-v server
If you try to add a cert now in the Hyper-v broker. You will see a nice error wrong or no certificate.
A cool thing in 2012 is that you can do PowerShell in the certificate store.
go to c:windowssystem32
use the :
cd .\localmachineroot then a Dir and you will see all the certificates
How cool is that !
Open an MMC and open the localmachine store.Requesting Hyper-V Replica Certificates from an Enterprise CA based on our current template.
Next and see here is our new certificate template
Now check the certificate and click on the blue line more information is required.
Use the CN = Common name / friendly name to identify the certificate. and use the computer names to connect to the certificate but you can also use the *.domain.local for a wildcard certificate
hit apply and the next on enroll
and in the certificate store the certificate should been listed
And that’s the process for customizing and requesting certificates. Your final step in configuring Hyper-V Replica happens back in Cluster Failover Manager.
now check the broker Role in the cluster and do right click
Launch replication Settings and click the Select Certificate button in Replication Configuration. If you’ve done everything correctly, you’ll see your recently installed and customized certificate
and I n my case I have two clusters and won’t to replicate from and to the both clusters.
there for I used the same certificate import and export with private key and put it on all the nodes remember the node name should be in the certificate FQDN !
In the VM you can enable replication and choose the certificate. But you can also mix one VM with Kerberos and the other with a certificate
Once It is done it is keep working unless the certificate is expired !
Next stop will be Hyper-v Replication Manager.
