What it is …

Download/obtain HDX 3D V1.1 from this source:https://www.citrix.com/English/ss/downloads/details.asp?downloadId=1858483&productId=163057

HDX 3D consists of 2 download packages:FFMpeg Open Source (not needed - the “source”)HDX 3D Pro GraphicsThe 12.0.33 online Plugin included in the package has been super-seeded by:

Do use the actual available Plugins (12.1/Nitro [13]) The 12.1 plugin is considered as stable and has indeed the HDX 3D GPU support built in.

What it is …

The RTM_with_12.0.1_client_health_Check_Tool package consists of:

CitrixOnlinePluginFull.exe 12.0.33 – [-> Use the 12.1 Plugin - super-seed.] Documentation (Administrator's Guide,

ReleaseNotes, User's Guide) HDX 3D Pro Graphics – HealthCheck.exe HDX3D_PROGFX_x64SERVERMSI.msi HDX3D_PROGFX_x86SERVERMSI.msi


What it is …

Recommendations/prerequisites for HDX 3D:

Actual plugins (12.1 and above on the client side)Older Plugins (e.g. 11.2) will just work – No HDX 3D acceleration could be expected in here.

Actual Workstation Hardware/Graphic Cards

Up to date NVIDIA ™ Graphic Drivers (CUDA Drv.)

An existing up and running XenDesktop 4 infrastructure should be in place. (up to date).


What it is …

The purpose of HDX 3D is to „stream“ graphical intense data via special Codecs to the end-user.

HDX 3D runs on bare metal workstations in the Datacenter with special GFX cards.

XenDesktop is used to broker the 3D workstation to the user(s)

HDX 3D is limited to 1 user-session/workstation.

Actual HDX 3D is available for XenDesktop 3, 4.

XenDesktop 5 support is planned – AFAIK with a SP, Feature Release (Codename “Alsace”)


What it is …

The codec is based on the open source FFMpeg http://www.ffmpeg.org/

No pictures or picture deltas are flying over the wire – It is a pure media-stream. Think of „movie-streaming“.

As GPUs are pretty faaaaaast today the GPU does all the conversion parts

e.g. CUDA - actual we have no FERMI support-> This is planned for the “Alsace” Release.

http://www.ffmpeg.org/


What it is …

HDX 3D usage scenarios can be widely seen in the CAD/CAM world.

Think of Solidworks (http://www.solidworks.com/)

Think of CATIA (http://www.3ds.com/)Think of the Autodesk product line (http://usa.autodesk.com/)

Use 3D Apps as you might know it from XenApp, XenDesktop

This is the brilliant idea behind HDX 3D.

http://www.solidworks.com/

http://www.3ds.com/

http://usa.autodesk.com/


What it is …

A typical usage example for HDX 3D (CATIA)


Why use HDX 3D NATed …

Think of security – external workers, companies, customers, etc.

Think of WAN/MAN infrastructures Think of branch offices Think of … The CLOUD

Configure NAT

NAT configuration – Big Picture


15

NAT configuration


Check the Web Interface Connection from ASCCreate a 2nd WI site (for internal/external access purposes)

Register/check within DNS – DNS reverse lookup.Check all routing entries – everywhere.Look out for ARP anomalies.Do watch for TCP latency.BTW:

(http://oss.oetiker.ch/mrtg/ - nice one – OS !)

http://oss.oetiker.ch/mrtg/



16

NAT configuration


Configure the Citrix WI for NAT

17

NAT configuration


Access Method -> Translated

18

NAT configuration


Edit the translated access method

19

NAT configuration


Type in all IP´s of the HDX 3D boxes Type in your corresponding NAT external IP address.

20

NAT configuration


Check out the firewall/router/NAT Settings

Taken from http://support.citrix.com/article/CTX118175:You also must configure port forwarding three times:on the firewall, router, and NAT. Here is an example with IPTABLES:# iptables –t nat –A PREROUTING –I eth0 –p tcp - -dport 1491 –j DNAT - -to-destination xxx.xxx.xxx.xxx:1494

Also, you must configure port forwarding for http to access the XenDesktop Server Web Interface: Port 80 (or 8080) to port 80 (or 8080) on IIS.# iptables –t nat –A PREROUTING –I eth0 –p tcp - -dport 80 –j DNAT - -to-destination xxx.xxx.xxx.xxx:80 (8080)

Notice that the port number is always different on an External interface (coming from the public IP – source port). The Internal port (destination port) is the same because XenDesktop Agent is listening on the same port on each computer.For common used ports see: http://support.citrix.com/article/CTX101810

21

NAT configuration


Add all internal HDX 3D Machines to the Web Interface translated configuration.

Just to be sure ICMP ping the HDX 3D boxes from within the Web Interface to ensure that the boxes are reachable.

You may use XDPing (http://support.citrix.com/article/CTX123278) to verify the ICA/HDX connection.

What could strike: http://support.citrix.com/article/CTX711855

Re-check your STA settings.



22

NAT configuration


Review all your settings, Re-check everything with the firewall/security gents.

This is “old school”. Think of a new Workstation kicking in or an IP-Address change.

You may have to touch every Firewall/Router/Routing Tables, etc.

The “Way Out”: Use a “transparent NAT”. A Netscaler ™ redundant powered CAGEE. This should be considered as the superior NAT related system – Advantage - A single point of administration.

Simulate an WAN EnvironmentUsing Linux netem

Home

24

WAN-Emulation

To simulate how Citrix HDX 3D performs in an WAN environment use netem

http://www.linuxfoundation.org/collaborate/workgroups/networking/netem

netem should be enabled in all actual Linux distros. Use the distribution of your choice – Build a Lab environment with a Linux box (at least 2 NICs) – configure as router [ e.g. https://help.ubuntu.com/community/Router] in between the test frontend (Client) and the backend XenDesktop with HDX 3D.




25

WAN-Emulation - Linux

Open a shell.switch to root e.g. sudo /bin/bash or su -

[type in your root password]We should be #root now, ma´am.


26


Type in (e.g.): tc qdisc add dev eth0 root handle 1:0 netem delay 100ms loss 0.2% corrupt 0.1% reorder 2%

[Return]Use replace if a configuration has already been applied


27



Verify your settings via tc -s qdisc show dev eth0Verify your settings with a ping –t from client side

28


To revert your settings to normal operation (default settings):

Type in tc qdisc del dev eth0 root tc -s qdisc show dev eth0

You can do WAN emulation with oracle SOLARIS ™ - If you dare ;-) See http://www.c0t0d0s0.org/archives/6625-Less-known-Solaris-feature

To Disable Disconnect - Create a new GPO: Edit the policy and change the following to

"enabled"

Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Remote Session Environment > Remove Disconnect option from Shut Down dialog.

42



Review the disconnection settings: Follow:

http://support.citrix.com/article/CTX127516 You may have to alter/manipulate the default

settings.

Ensure that the latest available Virtual Desktop Agent (VDA) is installed on the HDX 3D workstations –

WAN optimization/Packet shaping/QOS

could help – HDX 3D does need at least 1,5 Mpbs (Better 2 and up) – Remember – This does NOT accelerate HDX 3D in any way.

Citrix has an interesting offer: New XenDesktop Platinum Now Includes

HDX WAN Optimization at No Additional Charge !

See:

http://community.citrix.com/pages/viewpage.action?pageId=160366748



44



Use Quality of Service (QoS) e.g. on Port level.

To cross the borders of Jordan ;-)

WAN optimization can be done with Bluecoat ™ or the other usual suspects. (F5/Riverbed, etc.)
