VMware Thinapp 4.7.2 is now GA.

With VMware Release of Horizon Application Manager, there was some integration and changes required in thinapp to better support thinapp and also add some changes and features to help these two products to be tied together when available @ customer sites for better integration and increased management.

With That, VMware has happily announced the general availability of VMware Thinapp 4.7.2 where these features will improve usability, performance as well as updates functionalities.

  • Streaming – ThinApp agent is now able to stream the virtualized application blocks to stateless View desktops without deploying the entire package. For more information, see Knowledge Base article 2030247
  • Update Support – With this feature ThinApp can now enable Horizon Connector to recognize multiple versions of an application package and then communicate that change to the Agent through the Horizon Service. For more information, see Knowledge Base article 2030248
  • Relink Support – This feature allows ThinApp users to enable Horizon support for packages which are created prior to ThinApp 4.7 without a rebuild. For more information, see Knowledge Base article 2021928
  • New Sandbox Parameter – A new Package.ini parameter, RemoveSandBoxOnStart, is now available. You can set RemoveSandBoxOnStart=1 to clear the sandbox on each launch of an application.

SolarWind IP Address Tracker, I just Love it.

this is may be breif but i thought i just talk about it because it has really helped me a lot in saving my time looking for free and unallocated IP Addresses to use in my LAB environment. the way i use to do it before was by using Excel Sheets and notepad. Now the matter is lots simpler. all i have to do is to install the SolarWind IP Tracker and i will be in a very good shape.

 

The installation of the software is fairly simple and follow Next, Next Finish Fashion without the need to configure anything. once the software is installed and launched. you can configure the SUBNETS that you would like to track the IP Addresses for. the software supports multiple IP Subnets so you can simply add multiple Network subnets or in another word different VLANs to your interface.

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.

Stretched Cluster and vCenter Site Recovery Manager

With the advancement of storage and Networking Technologies, we can see a huge amount of benefits in the way datacenter are being operated today, we look at some solutions like T2 Stretched Network, Storage Technologies like storage virtualization and replications between different sites to increase availability and minimize downtime.

Although we understand how both these technology operates. It has changed our understanding of how we want to provide availability & Disaster recovery to our datacenters in so many different ways and it has given us the option to have multiple choices in case of wanting to implement whatever kind of protection or high availability.

But this understanding has started to be misleading sometime where enterprises has thought for once that creating stretched datacenter with virtualization is an option that provides both choices in term of disaster recovery and high availability.

However, this idea is completely misleading and an absolute wrong due to the thinking of high availability at very high level without thinking about the software options and configuration that can be implemented.

Using VMware HA Feature has been one of the great use cases implemented by customers and has so many design consideration. I have heard people talking about vSphere HA design that tolerate server failure, Chassis Failure as well as a full rack failure. But I have not worked on designing a solution with stretched cluster to tolerate site failure with VMware HA.

When implementing stretched cluster for VMware Environment, you achieve high availability for sure. However, in case of a full site loose what does really happen.

The answer to this question is simple, all machines are going to be restarted on the other site but what kind of control as an administrator do you have. The only control you have is basically 2 options.

1-      You can control is affinity/anti-affinity rules.

2-      You can configure High availability restart priority. High, medium and low.

As per the above 2 option, I don’t see any kind of dependency mapping in case of failure for example, what about one web applications that require at least 3 different virtual machines that depend on each other being available. (Database up & Running, then Application server up and running, then finally web server up and running). I have not seen VMware vSphere options that can control restart priority in that way.
