Desktop Performance Analytics Takes a Step Forward

Performance and scale testing of virtual desktop infrastructures has always been a challenge.  The known standard has been the testing suite from LoginVSI, and today they released their 4.0 product.  I have used LoginVSI quote a bit in the past and was given the opportunity to try a pre release of the product and I have to say that as always it has not disappointed.  I thought about a nice long description but they provided a nice bullet list that I did not have to write, so heres the plagiarism part of my post.

  • Improved ease of installation

The test image footprint of Login VSI has been reduced by almost 90%. This makes the tool not only easier to install, but also easier to integrate and deploy. Centralization of management, updates and logging makes the use of Login VSI more efficient than ever. Direct Desktop Launch (DDL) mode enables large-scale testing with minimal infrastructure.

  • Improved ease of test creation

The new intuitive and workflow oriented user interface of Login VSI 4.0 offers step-by-step test creation and wizard based test configuration for all important brokers and languages. The new workload editor introduces a new meta language which makes the customization of workloads very transparent and efficient. The new benchmarking mode enforces strict testing standards, providing industry standard results that are objective, comparable and repeatable.

  • Improved test realism

The duration of the standard workloads has been increased from 14 to 48 minutes loops. Also the way in which segments and applications start has been improved to better reflect real world user behaviour. The datasets used in the workloads now offer 1000 different documents per type, more and larger websites, and a video library in every format, all to ensure a real world variety in data usage. The execution of the workloads is improved through the introduction of phasing, allowing for real world production user scenarios.

  • Improved test insight

The new dashboard offers real-time test feedback, including progress, launched and active sessions, elapsed time and time left of the test in progress. The industry standard index VSImax has been further refined, enriching scalability results (max number of users), with objective baseline performance results (independent of tested load). Automated reporting with out of the box report ready graphs for all used settings, response times, and other data enhances the level, and choice, of information generated by the Login VSI analyzer.

Heres a nice gallery of screenshots for you as well..

My Old School Nintendo Setup to demo VDI at VMware PEX

Those of you that got to make it out to the VMware Partner Exchange probably got to see the demo in the Nexenta Booth.

Alot of the common social media geeks around virtualization got to swing by.  Chris Wahl from WahlNetworks included.  This was not an overly complex demo, but I wanted something fun to show off VDI sessions.  Using the real time performance metrics that are shown in NexentaVSA for View, we can actually see the systems running.

The install was rather easy, with one caveat.  VMware View does not recognize the Classic USB NES Controller for PC that we picked up from Amazon.

The great part is on the Lenovo Thinkpad I was using as a client I can make just a quick registry change and View will recognize.  This process is detailed here, very similar to restricting access, this allows you to add unknown USB devices to share to your View session.

The hardware was not very intense for the servers.  A couple Dell 1950 running ESX5.1 and using a Supermicro server with Nexenta installed as shared storage presenting 1 TB of NFS storage.  For the VDI hosts I put in 2 Cisco UCS C200 M2.  By adding in a single STEC ZeusIOP and a single spinning disk to house the desktops, and 96 GB of RAM we are able to build a rather robust VDI setup.  Allowing for about 100 desktops all being deployed with NexentaVSA for View..

By adding in the JNes Nintendo Emulator to the Windows 7 base images and VMware View Linked Clones, we have our own mini arcade.

 

Finally talking out my side project. vCloud and VDI in a Box

Over the past few weeks, I have been working on a side project with one of the Nexenta partners to prepare for the Intel Developers Forum in San Francisco this week. The partner Cirracore based in Atlanta works with Equinix and Telx pretty heavily and offers a few managed private and public cloud solutions. One of these solutions is based on the Intel Modular Server Chassis(IMS). If you have not checked out this chassis, it is probably one of the most engineered but least publicized piece of hardware I have seen in years. First to give you an Idea of what the chassis is made of, then two solutions we release this week, vCloud in a Box and VDI/SMB in a Box. Read more

How to make VDI easier to deploy? Take out the SAN, Take out the steps with Nexenta VSA for View

Deploying VDI should be an easy task, and with a proof of concept or trial it normally is.  The problems start to show up when you move from a small deployment to an enterprise rollout.  Problems like disk IO, throughput, management, and performance monitoring start to have a significant impact.  Nexenta has released their second product after working with VMware as just a way to ease that transition.  NexentaVSA for View(NV4V) is first an orchestration engine, followed by a performance tool.
