We are Moving

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.

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 you may have noticed there are a lot of virtualization products in the market.  Some of the better known products are from Parallels, Oracle, VMWare, and Microsoft.   Each company has products with different strengths and weaknesses.

I have spent a lot of time with various vendors support departments; and I have to say, Netapp has one of the best support departments.  If I call Netapp at 2:00 AM on a Sunday morning, I can get someone on the phone right away.  My one complaint is that I cannot open a ticket via E-Mail.  Fortunately that is not a big hurdle to cross.

When you are working with Netapp support you can either open a ticket over the phone or via the Now website.  If you do not have a NOW login, I would recommend getting one.  The NOW site is what will give you access to Netapp Documentation, Updates for your Filer, performance metrics from your Filer, and access to the support Portal.

Virtual Box is a very simple virtual machine package which can be installed on Linux, Mac, Windows, and Solaris. It is open source, so you can compile it to run on other systems as well.

In this tutorial video I will cover how to install virtual box and install your first virtual machine. The process of creating the virtual machine is does not change much from operating system to Operating system. As long as you know how to install the OS (Example: Windows or Linux) then you too can create a Virtual Machine. In this case I will be creating an Ubuntu Linux virtual machine. Ubuntu version 10.10 has a new installer, so it looks a little different if you have used previous versions, but it is still fairly intuitive.

When troubleshooting performance issues on a Netapp storage system, Perfstat is a very useful utility.  There are other ways to get performance statistics, but they are not quite as detailed.

The perfstat file at first glance can be rather daunting.  Perfstat files get very large, very fast, and may scare away the faint at heart.  But, if you spend a little time looking them over, they start to make some sense.

For the purpose of this article I am going to focus on three areas which will help you to pinpoint the performance problem you be experiencing on your SAN; these areas are Disk, CPU, and Network.
 

In the field of storage, you used to be able to simply buy enough hard drives to fill your space needs and you would end up with sufficient disks to fulfill your performance needs.  Unfortunately with hard disks getting so large, this is no longer the case.

When people talk about Virtualization, they are most of the time referring to either Machine Virtualization, or Application Virtualization.

When You Virtualize an application, you isolate the application to run it its own little world, sometimes called a Sand Box.  By doing this you can get around application compatibility issues, and simplify application deployment.

Welcome to the Site!

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.
