Most of the business today are choosing virtualization for Server consolidation, however along with that they get a lot more benefits:
- Reduce power and space requirement in data centres
- Fast application and service provisioning
- Improved manageability
- Business continuity
When these factors are measured by a survey taken by f5 few years a go we got the following results.
This clearly explains that the Businesses are focused to do server consolidation and reduction of power and space requirement which is the driving factors even today.
The types of virtualization do we currently have ? as discussed this on my previous post, I am going to compare them today.
According to surveys taken recently we have the following stats.
This clearly explains us that most of the Virtualization technologies are been used today, however still the most popular one is Server virtualization. Never the less this is taken on a different level today to get the Desktop virtualization for the end users companies like Citrix and VMware have got a lot of powerful products for this.

I have a question today?
How fussy are you to which Wi-Fi signal you connect? i.e., connecting to an open or a secure Wi-Fi connection.
As we know that most of the Coffey shops and pubs allow you to use the free Wi-Fi open connections. Do you even think twice before connecting to a open Wi-Fi signal?
Please put some time to understand what is the risk involved in using an open Wi-Fi connection.
I know getting internet connectivity when your out and about will look like a blessing. However all your data and your laptop itself can be compromised by anyone connecting to open Wi-Fi connections.
Some people think that having a Anti-Virus program or an Firewall enabled laptop will keep them safe, what they don’t know is when they setup the connection with an open Wi-Fi connection they have already established a trust relation with that router.
Windows 7 gives warning to the user that its very risky to connect to a Open and un-secure Wi-Fi networks yet most of the people I know still connect anyway.
Moreover I know a couple of friends who bought a wireless router and started using it without setting up of security key or changing the default admin password. Continue reading “Are you Secure when you browse the web ?”
Last week I was on a workshop by Microsoft it was for troubleshooting performance issues on Servers.
One of the interesting thing which I came across in the workshop was about the memory management and the way Windows handles the memory.
By default Windows allocate’s virtual address space to User mode and Kernal mode, Windows assumes that it has 4 gb of virtual address space and it splits it into two half.
ie. 2 GB virtual address space to Kernal and 2 GB virtual address space to User
We can tweak it and allocate virtual address space to programs 1 GB to the kernel and to executive component.
This is how you can do it:
First un-hide the hidden files and folder make sure you unhidden the Operating system files too.
on the root directory ie C drive you will find boot.ini file take a backup of it on keep it safe.
Edit boot.ini and add \3GB at the end Continue reading “Memory Support in Windows – Kernal v User Virtual Addressing”
Last Friday I have virtualized my Windows XP Laptop, before I start telling you guys, how its done I think its worth mentioning why I need to do it?
We normal Virtualize the physical server that are very old and start getting faults very often or they are too big for us to keep in our data centres.
I have dual booted my laptop with Windows 7 ’64 bit’ edition, Which works brilliant. However Win7 is as this is 64 bit version of Windows I had to work around quite a few applications which I use on daily basis to get them work on Win7.
However the most important software which I need to work from home is the vpn client provided by CISCO. The VPN client is yet to be rewritten for Win ’64 bit’ CPU. As a result I could not use Win7 to work from home, as I was unable to install VPN client to deil.
Now you can guess why I virtualized my Windows XP OS. Continue reading “How to Virtualize Your Computer”
