Storage Replication Configuring Jobs - Part 4

Introduction
In the previous article, I have more and less cover the needs that you need to know when you want to plan the storage replication in your organization. Planning is very important in the initial stage. On this article I will cover more toward on how to configure storage replication on a different server over a wan link.

Configuration
In this lab configuration, I have use 2 server to simulate the replication which is virtual01 and virtual02. As you can see the screen below, I have open the SteelEye management console screen from virtual01. For your information you can open the console from any machine that have been installed with the software.

What we need to do now is to configure a storage replication from virtual01 to virtual02. We want to replicate the Z drive from virtual01 to virtual02. Make sure the remote storage on the virtual02 is bigger than virtual01.Before you can start to create any job, you must link the server to the SteelEye by clicking on the connect to the server. If you have 3 server, you will need to configure all the 3 servers.

This is what it will prompt when you click on the connect to the server

Once you are done with the configuration, now we need to create a job or a task that is going to perform the storage replication

Will suggest you to put a meaningful name, so that you can have a better management on labeling.

Once you click on next, you will need to specificy the source server which is virtual01. As you can see on the IP address I have use 10.0.0.x which is dedicated for replication. While on the volume, I have configure it just to replicate drive Z whereby all my vhd reside.

On the target, you will need to do the same

Depending on your prefer option, as above will be the prefer option. As I have mention earlier in my article which cover the type of replication on asynchronous and synchronous. You might want to reconsider which option that you prefer

You will see that the state in recyncing

On the remote host, you will notice that the entire volume is lock.You can't open the drive to change anything. This is to protect the integrity of the data

But if would like to check the remote host drive volume, you always can pause the state of the replication.

This is a good sign of a healthy replication

On the screen above, if you notice the host turn into red and the status is showing mirroring. This is where by the remote host have been shutdown.
