While working on the project I was asked a question whether EMC VPLEX is supported with VMware SRM and whether do we really need to have SRM if we are using EMC VPLEX.

I thought I will start a open discussion for the same and start researching

Let me start with putting some basic information about both

1. EMC VPLEX :- It achieves transparent, dynamic and non-disruptive distribution of storage resources across self-governing, discrete, peer storage systems. When used in Combination with vSphere it can balance workloads between two datacenters, with non-disruptive workload mobility enabling migration of services between geographically close sites without the need for sustaining an outage known as Stretched Clusters

2. VMware SRM - offers a different primary goal, focused primarily on configuring, automating and reporting on a repeatable and robust disaster recovery process. The primary goal of Site Recovery Manager is to provide managed and consistent automated processes for restoring services after an outage, coupled with non-intrusive testing and reporting for routine confirmation of the capability of restored services.

While researching for the same, I found couple of interesting articles / whitepaper. I thought i might share it for starters.

1. Stretched vSphere Clusters? DR with SRM? Why not BOTH?
2. Stretched Clusters and Site Recovery Manager

CloudStack Installation

Installing CloudStack without an Internet Connection

In order to install CloudStack where you don’t have access to internet (i.e. LAB Setup) we need to setup a local repository from the Cent-OS DVD
1.       Ensure all the other default repos are disabled.

2.       We need to create a repo file which includes the base url as media/centos6.2_final

Install the Management Server

1.       Copy the CloudStack setup to the Base OS

2.       Unzip the file and start the installation using ./
3.       When the installation is finished, run the following commands to start essential services

Install the MySQL Database

1.       Start the database installation using ./
2.       Edit the MySQL configuration (/etc/my.cnf or /etc/mysql/my.cnf, depending on your OS) and insert the following lines in the [mysqld] section. You can put these lines below the datadir line. The max_connections parameter should be set to 350 multiplied by the number of Management Servers you are deploying.
