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!

Friday Tips #3

Even though yesterday was Thanksgiving here in the US, we still have a Friday tip for those of you around your computers today. In fact, we have two! The first one came in last week via our #AskOracleVirtualization Twitter hashtag. The tweet has disappeared into the ether now, but we remember the gist, so here it is:


Question:
Will there be an Oracle Virtual Desktop Client for Android?

Answer by our desktop virtualization product development team:
We are looking at Android as a supported platform for future releases.


Question:
How can I make a Sun Ray Client automatically connect to a virtual machine?

Answer by Rick Butland, Principal Sales Consultant, Oracle Desktop Virtualization:
Someone recently asked how they can assign VM’s to specific Sun Ray Desktop Units (“DTU’s”) without any user interfaction being required, without the “Desktop Selector” being displayed, or any User Directory.  That is, they wanted each Sun Ray to power on and immediately connect to a pre-assigned Solaris VM.  

This can be achieved by using “tokens” for user assignment – that is, the tokens found on Smart Cards, DTU’s, or OVDC clients can be used in place of user credentials.  Note, however, that mixing “token-only” assignments and “User Directories” in the same VDI Center won’t work.  

Much of this procedure is covered in the documentation, particularly here. But it can useful to have everything in one place, “cookbook-style”: 

1. Create the “token-only” directory type:

From the VDI administration interface, select:

 “Settings”, “Company”, “New”, select the “None” radio button, and click “Next.”

Enter a name for the new “Company”, and click “Next”, then “Finish.”

2. Create Desktop Providers, Pools, and VM’s as appropriate.

3. Access the Sun Ray administration interface at http://servername:1660 and login using “root” credentials, and access the token-id’s you wish to use for assignment.  If you’re using DTU tokens rather than Smart Card tokens, these can be found under the “Tokens” tab, and “Search-ing” using the “Currently Used Tokens” tab.  DTU’s can be identified by the prefix “psuedo.”   For example:


4. Copy/paste this token into the VDI administrative interface, by selecting “Users”, “New”, and pasting in the token ID, and click “OK” - for example:

5. Assign the token (DTU) to a desktop, that is, in the VDI Admin Gui, select “Pool”, “Desktop”, select the VM, and click "Assign" and select the token you want, for example:


In addition to assigning tokens to desktops, you'll need to bypass the login screen.  To do this, you need to do two things: 

1.  Disable VDI client authentication with: 

/opt/SUNWvda/sbin/vda settings-setprops -p clientauthentication=Disabled

2. Disable the VDI login screen – to do this,  add a kiosk argument of "-n" to the Sun Ray kiosk arguments screen.   You set this on the Sun Ray administration page - "Advanced", "Kiosk Mode", "Edit", and add the “-n” option to the arguments screen, for example:

3.  Restart both the Sun Ray and VDI services:

# /opt/SUNWut/sbin/utstart –c
# /opt/SUNWvda/sbin/vda-service restart


Remember, if you have a question for us, please post on Twitter with our hashtag (again, it's #AskOracleVirtualization), and we'll try to answer it if we can. See you next time!

Friday tips #2

Welcome to our second Friday tips blog! You can ask us questions using the hash tag #AskOracleVirtualization on Twitter and we'll do our best to answer them.

Today we've got a VDI related question on linked clones:

Question: I want to use linked clones with Oracle Virtual Desktop Infrastructure. What are my options?

Answer by John Renko, Consulting Developer, Oracle:

First, linked clones are available with the Oracle VirtualBox hypervisor only.

Second, your choice of storage will affect the rest of your architecture.

If you are using a SAN presenting ISCSI LUNS, you can have linked clones with a Oracle Enterprise Linux based hypervisor running VirtualBox. OEL will use OCFS2 to allow VirtualBox to create the linked clones. Because of the OCFS2 requirement, a Solaris based VirtualBox hypervisor will not be able to support linked clones on remote ISCSI storage.

If you using the local storage option on your hypervisors, you will have linked clones with Solaris or Linux based hypervisors running VirtualBox.

In all cases, Oracle Virtual Desktop Infrastructure makes the right selection for creating clones - sparse or linked - behind the scenes. Plan your architecture accordingly if you want to ensure you have the higher performing linked clones.

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.

Welcome to our Friday tips series!

Today we're starting a brand new blog series. For your Friday afternoon reading, we'll be posting a technical tip or question and answer on a technical topic. We'll start by introducing ideas on our own, but we'd really like it if you were involved and asked us questions via Twitter! Tag your tweet with #AskOracleVirtualization and we'll consider your question for the blog.

Today's tip is on Storage and Oracle Virtual Desktop Infrastructure:

Question: I run Oracle Virtual Desktop Infrastructure 3.4.1 on Solaris and use a local ZFS storage pool.  How should I configure my ZFS ARC cache? 

Answer by John Renko, Consulting Developer, Oracle:

Oracle recommends about 5G of ARC cache per template in use to achieve up to a 90% disk read offload. Set your ARC min=max to reserve the maximum amount of your remaining memory for your running VMs. In /etc/system:

set zfs:zfs_arc_min = 5368709120
set zfs:zfs_arc_max = 5368709120

The amount you need to reserve will depend on your template but this has proven to be a great start for a typical windows 7 VM running productivity applications.

Videos from BriForum Chicago 2012

We had a really wonderful show at BriForum Chicago last week! Thanks to everyone for stopping by our booth and coming to our session. It was great to meet all of you, answer questions, and get to hear about how you're using desktop virtualization.

We recorded some videos at the show, and got into a couple of areas we haven't yet touched on. One, is a video in Spanish by Jorge Angel. Another really interesting one is with Brad Lackey where explains the architectural security differences with Oracle Virtual Desktop Infrastructure. We also have a video from our featured speaker Phillip Fiedler from Open Technologies, giving a quick summary of his session. Really interesting stuff! Here are the videos we did on the show floor:

This is the official video made by the brianmadden.com folks of our demo. The video is hosted there, so you'll need to click the thumbnail here and hop over to their page to see it, but it's worth it!

BriForum 2012 - Oracle Virtual Desktop Infrastructure Aligns with the Experts.

BriForum 2012 in Chicago includes great sessions from industry experts and consultants focused on VDI and Server Based Computing.   One session delivered by Ron Oglesby of Unidesk presented "How you can solve common problems with VDI".  As VDI deployments have increased in size a major challenge as been optimizing storage to deliver the IOPS required for desktop workloads.  This requirement often is in conflict with the goals of reducing the CAPEX investment of implementing VDI.

Ron Oglesby recommends the use of "Hybrid Storage Arrays" that provide a combination of large controller memory,  Solid State Disk (SSD) for high IOPS,  combined with lower cost array disks.   He then asks if anyone has heard of ZFS

When you consider this general recommendation from Ron, it aligns with the Oracle Virtual Desktop Infrastructure solution that for years has taken advantage of the Sun ZFS Storage Appliance.  Otherwise considered a "Hybrid Storage Array" that as Ron generically suggests works very well for desktop workloads.

Ron goes on to mention the option of using local storage for lowering the CAPEX cost for VDI that can provide high IOPS with the lower cost of internal disks within the hypervisor server.   Local storage is not for all deployments but can certainly be used for deployments such as flexible desktops without high availability requirements. 

The latest release of Oracle Virtual Desktop Infrastructure aligns well with this recommendation by supporting fast local storage installed on servers running the Oracle VM VirtualBox hypervisor.   The Oracle VM VirtualBox hypervisor when installed on Oracle Solaris can provide the local storage with ZFS combined with the large server memory footprint available with Oracle Servers.  Additionally, the Oracle VM VirtualBox hypervisor can be deployed onto Oracle Linux and leverage the Oracle Cluster Files System V2 (OCFS2) combined with the large memory available with Oracle Servers.

The Oracle Virtual Desktop Infrastructure strategy that leverages hardware and software optimized for delivering virtual desktop workloads clearly is lining up with recommendations from virtual desktop experts.

Live from the show floor at BriForum Chicago 2012

The Oracle desktop virtualization team is on the show floor here at day 2 of BriForum in Chicago. As you might have read on this blog before, BriForum is just a fantastic event. The sessions here cover current industries trends and best practices, but my favorite sessions are the "thought leaders" style talks. There are a lot of really smart people at this show and they share their latest thinking on desktop virtualization with the attendees. Think TED talks, but focused on desktop virtualization. Really great stuff.

Oracle is very proud to be a platinum sponsor of this event. We're sponsoring giveaways, lunch tomorrow, and we have a nice booth showing off our desktop virtualization portfolio. We also had a speaking session yesterday that featured Brad Lackey from Oracle and Phillip Fiedler from our partner Open Technologies. Brad and Phillip gave the crowd some real world tips for deploying VDI, with a focus on the healthcare use case.

To get a sense of what we're doing here, you can head over to the Oracle virtualization YouTube channel. We've posted a couple of videos there already, with more to come. 

If you missed us at BriForum, keep an eye on this blog, Twitter, and Facebook for your next opportunity to see Oracle desktop virtualization in person. And if you're going to Oracle OpenWorld, there are a number of sessions you can attend focused on desktop virtualization.

Oracle Virtualization at Oracle OpenWorld 2012 Part 3

Mini-Series Entry 3 of 3: Server Virtualization Sessions

This is the third entry of a three part mini-series looking at Oracle server and desktop virtualization at Oracle OpenWorld 2012.

In our previous entries, we covered the Oracle Virtualization keynote session, hands on labs, and desktop virtualization sessions. Below are four key sever virtualization sessions for you to enjoy at this year's Oracle OpenWorld.

Session ID: CON6814
Ready to get more value from your server virtualization investment? In this practical session, experts from Verizon and Oracle explain how to get the real benefits of IT flexibility, agility, and efficiency by using server virtualization while saving time and money and avoiding hassles. Discover tips and tricks for using Oracle VM 3, Oracle Linux, and Oracle Enterprise Manager 12c to rapidly deploy enterprise applications in hours or days instead of weeks. Learn about innovations for automating all deployment functions, and hear about best practices for configuring and managing networks and storage. The session will help you save time and money, reduce data center errors, and help you realize the full potential of server virtualization.

Session ID: CON8487
The latest generation of Oracle Real Application Clusters (Oracle RAC) and database technology provides an agile database deployment infrastructure optimized for running on bare metal hardware. The same architecture can be used on Oracle VM to further benefit from template-based deployments or virtualization-based environments in general. Attend this session to understand the key considerations for transitioning to or running Oracle RAC in an Oracle VM-based environment. The session includes a live demo showing how the new deploy cluster tool streamlines deployment of Oracle RAC.

Session ID: CON8727
Many IT organizations need different OS and hardware to address stringent service levels and meet competitive pressures. Oracle VM enterprise-class server virtualization offers a high-performance architecture and the broadest workload support. It provides server virtualization for Oracle's x86 and SPARC architectures plus tight integration support for OSs such as Linux, Oracle Solaris, and Windows. Oracle VM Server virtualization gives users the best combination of price, performance, certification, and advanced features to make the entire software/hardware stack for enterprise applications easier to deploy, manage, and support. This session covers the latest Oracle VM technology updates and transforming your data center to the next level of efficiency while reducing operating costs.

Session ID: CON8734
Virtualization has changed how IT delivers information and business services. As IT organizations migrate from traditional computing data centers to cloud-based infrastructures, traditional virtualization offers only part of what the migration requires. Stacks of enterprise applications driving crucial business services and management orchestrations-hardware to software to cloud-based services-are fundamental ingredients of a successful migration. This session covers Oracle's virtualization and management offering: Oracle VM, its integration with Oracle Linux, and cloud control/lifecycle management with Oracle Enterprise Manager. See how the Oracle VM/Oracle Virtual Assembly Builder 11g integration can help you simplify and standardize enterprise application deployment to the cloud.

Session ID: CON8735
You've consolidated your server farms-mail servers-but what about enterprise application workloads, database, business apps? These are crucial and are running on Oracle Solaris, Linux, and Windows. How hard is it to manage this application sprawl? This session shows the benefit of Oracle VM for virtualizing Oracle and how Oracle VM Templates have foundational tools for speeding enterprise application workload virtualization for rapid deployment of applications such as Oracle Database and Oracle's Siebel Customer Relationship Management. You'll learn about recipes for deploying applications with more than 90 predefined Oracle VM Templates for your Oracle applications, in minutes, not days or hours. You'll also hear how to manage virtualized application sprawl with Oracle Enterprise Manager.

Session ID: CON7393
Cloud computing can be implemented in several ways: public, private, hybrid, or community. To add to the deployment choices, cloud computing services can be offered as infrastructure as a service (IaaS), platform as a service (PaaS), or software as a service (SaaS), with or without full self-service capabilities. This session lays down the foundations for business cases for going to the cloud, using key common drivers and common use cases.

  • Outsourcing 
  • Core competency 
  • Portfolio rationalization 
  • Infrastructure consolidation

As we get closer to the event, we'll do another post on the virtualization product demos you'l be able to see at the show. And remember, there are over 1,700 more Oracle OpenWorld sessions in the content catalog.

We look forward to seeing you at Oracle OpenWorld 2012 on September 30th!
