Thank you to everyone who have supported us since our inception. We will be moving to our new site in the coming months. So please check it out at: www.idkrtm.com We will be migrating all the content over, so you don't have to worry about losing anything.
Today is the second day of VMWorld and we heard from from VMWare's old CEO Paul Maritz new CEO Pat Gelsinger on the direction the company is taking. In the last four years we have seen server virtualization in the enterprise go from 25% penetration to approximately 60% penetration. VMWare has an 80% marketshare in virtualization so this shows a huge growth for the company. In the next four years VMWare would like to see 90% adoption of virtualization in the enterprise.
When you think of the beginning of Server Virtualization, companies like VMWare may come to mind. The thing you may not realize is Server Virtualization actually started back in the early 1960’s and was pioneered by companies like General Electric (GE), Bell Labs, and International Business Machines (IBM).
When considering your storage systems you will be faced with many choices covering a whole range of price ranges. In this chapter I will cover some of the differences and similarities between consumer grade and enterprise grade equipment.
Disaster recovery can be a difficult thing to plan for. You back up your systems; perhaps you replicate your data to an off-site facility; maybe you even build all redundant systems.
After doing all of these things, what is your goal? It is to get your systems back up and running after some sort of a disaster, such as your building burning down; or an electrical failure in your data center.
Below I have listed a few possible scenarios you may encounter. In these scenarios I outline a few problems you may encounter, but from a Server Prospective. The network recovery is for another article.
As there are a variety of tasks you may need to achieve, there are many different ways to connect to your storage system. Each operating system has differing methods for utilizing these protocols, and different operating systems will perform differently with each protocol. For the purpose of this article we are going to focus on two methods of connecting to storage; LUN’s and File Shares. In my examples I will be using Open Filer as the storage device, then various Linux and Windows editions to connect to the storage system.
In this article I will be covering only the client side of things. You can see my article on Configuring Open Filer if you wish to quickly setup the server side of any of the protocols I have outlined in this article. In the future I will post more articles detailing how to create shares without using a pre-packaged solutions like Open Filer.
Welcome to EverythingVM.com Here at Everything VM you will be able to find information on various Storage and Virtualization platforms. I will try to focus on less expensive solutions, but I will work my way up into enterprise solutions as well.
I hope to be informative, and please feel free to send me your questions, and I will do my best to answer them.
