Accelerate VMware View over WAN with Riverbed

one of the most common questions that i get from my customer about View using UDP as per my previous blog post that how do we accelerate PCoIP and increase or even extra optimize the performance in VMware View. The Answer to this is actually very simple. in my case, the way people think about optimizing the traffic is all about TCP and you can never use WAN Optimizer for UDP traffic because one of the main advantages of WAN optimizers is that it caches acknowledgement which is the case when using TCP protocol.

keep in mind that with View 5.1, the optimization has gone so far that the customers are really happy with the performance they are getting out of the box after the installation. i have done default settings, no changes no optimization and the results were just as amazing. weather over WAN inside the enterprise or even 3G Connections in different rooms and roaming around the enterprise building.

what they didn’t know is that specifically for PCoIP, VMware has partnered with multiple companies to do WAN optimization for PCoIP Protocol. today my discussion is about how Riverbed does it.

so when using Riverbed WAN optimization for PCoIP the architecture we will get with is from Riverbed themselves is as follows.

There are 2 Riverbed Steelhead® appliances running RIOS 7.0.0 with Full optimization enabled at the branch and in the Data Center. The Virtual Desktops and infrastructure are hosted on a VMware ESXi Server 5.0. The View Connection server 5.0 is used for authentication and allocation of Virtual Desktops to branch users.

there are two modes for Steelhead, Cold & Warm, when riverbed did the testing, the following are the result of these testing exercises.

 

USB Redirection (mass storage) File Copy Test – Time
The File copy test chart shows the time (in seconds) to complete the File copy operation on files of different types and sizes, and directories containing multiple files, again of different types and sizes. With Steelheads in the network the file transfers are always faster than when no Steelheads are present. It is important to notice that the Warm runs show an improvement of 45% time to complete file transfers.

USB Redirection (mass storage) File Copy Test – Data Usage
The File copy test chart shows the WAN bandwidth usage (data transferred in MB) to complete the File copy operation with files of different types and sizes, and directories containing multiple files, again of different types and sizes. With Steelheads in the network the file transfers are always faster than when no Steelheads are present. It is important to notice that the Warm runs show an impressive 94% reduction in the data transferred over the WAN to complete file transfers.

 

Steelhead Data Reduction Report
The Steelhead Optimization Reports below shows the Total Data Reduction % achieved for VMware View PCoIP USB Redirection to copy files from the USB mass storage to Virtual Machine. The screenshot on the left shows 63% Data Reduction achieved with cold optimization on the Steelhead. The screenshot on the right show 96% Data Reduction achieved with Steelhead appliances using warm optimization.

 

 

so as WAN optimization solutions for PCoIP there are so many of them and the wrong understanding from the customer about how the WAN optimizers actually works in term of PCoIP in adding compression, encryption and tuning capabilities to add to PCoIP.
