Erik Scholten has published a brilliant article about video performance in VMware View on the VMGuru Blog. He has been very busy in the last few weeks with VMware View deployments at this customers and could manage to improve the video performance by tweaking the configuration a bit.
Erik Scholten is the founder of VMGuru.nl and works for Imtech ICT as a Solution Architect creating the most ingenious virtual infrastructures. He has over 15 years experience as a system engineer and consultant and now he specializes in virtualization. His current job includes selling, presenting, designing and developing virtual infrastructures for some major companies in the Netherlands. In 2009, 2010, 2011 and 2012 VMware awarded him the vExpert award for his virtualization community efforts.
I’ve learned that a Windows Xp to Windows 7 Migration is tough for loads of customers as the tools they mostly use aren’t easy to work with. Check out this video about an In-Place migration of Windows XP to Windows 7 with VMware Mirage.
When visiting the VMware View Download page at www.vmware.com today I’ve got a notice about a new knowledge base article which was published back in December 2012. If you’re using the View Agent on a physical desktop computer to get remote access to it you might face some performance issues or will have an decrease in stability. This symptoms can only be seen on physical desktop, NOT virtual desktops in a VDI.
Only the agent version 5.1.2 seems to be affected.
Teradici has updated the firmware for their PCoIP zero clients to version 3.4 and the Management Console to 1.5.30. The following list gives you an overview of the new functionality.
PCoIP Firmware Release 3.4 enhancements include:
- Support for “T=1″ PIV CAC Smartcards
- Enhanced Event Log and configuration options, including Syslog support
- Added support for Czech, Slovenian and Romanian keyboard layouts
PCoIP Management Console 1.5.30 enhancements include:
- Device auto-configuration to automatically group and configure newly discovered PCoIP zero clients
- Profiles now include firmware file and On-Screen-Display (OSD) logo options
- Profile application to groups or individual devices can be scheduled for a future time
Update: I want to clarify that I of course know that network connections all over the world are different in speed, latency and packet loss. My video only shows that my ad-hoc connection from Europe to the West Coast just works well and the video/website mentioned in this article could give the readers/watchers/listeners are wrong impression of PCoIP.
This week I was really surprised about an blog article I saw linked on Twitter. In the article/videos the author shows a virtual desktop connected over PCoIP from San Francisco to Ottawa. For more details on the scenario please check the article and also listen to the speaker in video. He said: “Definitely much much worse than ICA was…”. Well the “real world” scenario as he describes it looks really strange to me. Ok, he’s connecting from a hotel internet connection (which is mostly crap, but in SF?) via VPN to his data centre but only on one continent with a distance of approximately 5100km (Maybe the cable is going a longer way…). I know PCoIP and is has definitely a much better performance on the WAN and I checked it. This is my real world example: My connection is from my home office’s DSL line through the VPN to the data centre in California.
A ping from my local workstation to the View Manager Server looks like that: (Doh! 382ms)
64 bytes from xx.xxx.xx.xx: icmp_seq=2 ttl=242 time=382.313 ms
64 bytes from xx.xxx.xx.xx: icmp_seq=3 ttl=242 time=382.777 ms
64 bytes from xx.xxx.xx.xx: icmp_seq=4 ttl=242 time=382.545 ms
64 bytes from xx.xxx.xx.xx: icmp_seq=5 ttl=242 time=382.215 ms
And the result looks like that:
I think this is great for an overseas connection and watching a video, hah? Sometimes it hangs for a short time but 382ms!
