Friday Tips #4

It's time once again for our Friday tip. Our question today is about how to determine how much video RAM to allocate for your virtual machines in a VDI deployment:


Question:
How much video RAM do I really need on my VirtualBox VMs?

Answer by John Renko, Consulting Developer, Oracle:
The answer is in the VirtualBox admin guide but it's seldom followed correctly, usually resulting in excess unused RAM to be allocated. The formula for determining how much RAM to allocate is shown below for a 32 bit fullscreen 22" monitor supporting 1680x1050:

bit depth / 8 x horizontal res x vertical res / 1024 / 1024 = MB RAM

Which translates to:

32 bits / 8 x 1680 x 1050 / 1024 / 1024 = 6.7 MB

If you wanted to support dual 22" monitors, you would need twice that, so 13.4 MB.

Anything in excess of what is needed is readily allocated but not used and would be better suited for running more VMs!


Thanks John, that tip should help folks squeeze a little more out of their VDI servers. And remember, if you have a question for us, use hash tag #AskOracleVirtualization on Twitter.

We'll see you next week with another tip!

IDC Client Virtualization MarketScape 2012

IDC recently published their annual "MarketScape: Worldwide Client Virtualization Vendor Analysis" report. Customers use this document to compare desktop virtualization vendor offerings. In the 2012 report, Oracle is categorized as a "Major Player".

DOAG 2012 and Educause 2012

Oracle understands the value of desktop virtualization and how customers have really embraced it as a top tier method to deliver access to applications and data. Just as supporting operating systems other than Windows in the enterprise desktop space started to become necessary perhaps 5-7 years ago, supporting desktop virtualization with VDI, application virtualization, thin clients, and tablet access is becoming necessary today in 2012. Any application strategy needs to have a secure mobile component, and a solution that gives you a holistic strategy across both mobile and fixed-asset (i.e., desktop PCs) devices is crucial to success.

This means it's probably useful to learn about desktop virtualization, even if it's not in your typical area of responsibility. A good way to do that is at one of the many trade shows where we exhibit. Here are two examples: 

DOAG 2012 Conference + Exhibition

The DOAG Conference is fast approaching, starting November 20th in Nuernberg, Germany. If you've been reading this blog for a while, you might remember that we attended last year as well.

This conference is fantastic for us because we get to speak directly to users of Oracle products. In many cases, those DBAs, IT managers, and other infrastructure folks are looking for ways to deal with the burgeoning BYOD model, as well as ways of streamlining their standard desktop and access technologies. We have a couple of sessions where you can learn a great deal about how Oracle can help with these points.

Session Schedule (look under "Infrastruktur & Hardware")

The two sessions focused on desktop virtualization are:
  • Oracle VDI Best Practice unter Linux (Oracle VDI Best Practice Under Linux)
  • Virtual Desktop Infrastructure Implementierungen und Praxiserfahrungen (Virtual Desktop Infrastructures Implementations and Best Practices)
We will also have experts on hand at the booth to answer your questions on using desktop virtualization. If you're at the show, please stop by and say hello to our team there!

Educause 2012 

Another good example is Educause. We've gone the last few years to show off a slough of education oriented applications and capabilities in the Oracle product portfolio. And every year, we display those applications through Oracle desktop virtualization. This means the demonstration can easily be setup ahead of time and replicated out to however many "demo pods" that we have available. There's no need for our product teams to setup individual laptops for demos -- we can display a standardized Windows desktop virtual machine with their apps all ready to go on a whole bunch of devices like your standard trade show laptop, our Sun Ray Clients, and iPad.

Educause 2012 just wrapped, so we're sorry we missed you this year. But there is always next year! Until then, here are a few pictures from this year's show:

You can also watch this video to see how Catholic Education Australia uses Oracle Secure Global Desktop to help cope with the ever changing ways that people access their applications.
