Leave a reply

In the blog here, we just published the updated white paper VMware Horizon 6 with View Performance and Best Practices that describes the performance gains achieved with the latest Horizon 6 enhancements. The paper details the architecture systems used for testing the features and recommends best practices for configuring your system.

The white paper talks about the following performance results:

  • RDSH sizing
  • Display protocol performance
  • PCoIP default settings changes
  • VDI characterization on Virtual SAN

Finally, some of the best practices are presented:

  • RDSH virtual machine sizing
  • RDSH session sizing
  • RDSH server virtual machine optimization
  • Guest best practices for bandwidth and storage
  • PCoIP settings
  • 3D graphics settings
  • Virtual SAN configurations

Please check out the VMware Horizon 6 with View Performance and Best Practices  paper for detailed descriptions of the tests, the results of those tests and the best practices.

 

VMware View Planner 3.5 and Use Cases

4 Replies

by   Banit Agrawal     Nachiket Karmarkar

VMware View Planner 3.5 was recently released which introduces a slew of new features, enhancements in user experience, and scalability. In this blog, we present some of these new features and use cases. More details can be found in the whitepaper here.

In addition to retaining all the features available in VMware View Planner 3.0, View Planner 3.5 addresses the following new use cases:

  • Support for VMware Horizon 6  (support of RDSH session and application publishing)
  • Support for Windows 8.1 as desktops
  • Improved user experience
  • Audio-Video sync (AVBench)
  • Drag and Scroll workload (UEBench)
  • Support for Windows 7 as clients

In View Planner 3.5, we augment the capability of View Planner to quantify user experience for user sessions and application remoting provided through remote desktop session hosts (RDSH) as a sever farm. Starting this release, we will support Windows 8.1 as one of the supported guest OSes for desktops and Windows 7 as the supported guest OS for clients.

New Interactive Workloads

We also introduced two advanced workloads: (1) Audio-Video sync (AVBench) and (2) Drag and Scroll workload (UEBench). AVBench determines audio fidelity in a distributed environment where audio and video streams are not tethered. The “Drag and Scroll” workload determines spatial and temporal variance by emulating user events like mouse click, scroll, and drag.

As seen in Figure 1, a mouse event is sent to the desktop and the red and black image is dragged across and down the screen.

Similarly, Figure 2 depicts a mouse event sent to the scroll bar of an image that is scrolled up and down.

Better Run Status Reporting

As part of improving the user experience, the UI can track the current stage the View Planner run is in and notifies the user through a color-coded box. The text inside the box is a clickable link that provides a pop-up giving deeper insight about that particular stage.

Pre-Check Run Profile for Errors

A “check” button provides users a way to verify the correctness of their run-profile parameters.

 In the past, users needed to optimize the parent VMs used for deploying clients and desktop pools. View Planner 3.5 has automated these optimizations as part of installing the View Planner agent service. The agent installer also comes with a UI that tracks the current stage the installer is in and highlights the results of various installer stages.

Sample Use Cases

Single Host VDI Scaling

Through this release, we have re-affirmed the use case of View Planner as an ideal tool for platform characterization for VDI scenarios.  On a Cisco UCS C240 server, we started with a small number of desktops running the “standard benchmark profile” and increased them until the Group A and Group B numbers exceeded the threshold. The results below demonstrate the scalability of a single UCS C240 server as a platform for VDI deployments.

Single Host RDSH Scaling

We followed the best practices prescribed in the VMware Horizon 6 RDSH Performance & Best Practices whitepaper  and set up a number of remote desktop session (RDS) servers that would fully consolidate a single UCS C240 vSphere server. We started with a small number of user sessions per core and then increased them until the Group A and Group B numbers exceeded the threshold level. The results below demonstrate how ViewPlanner can accurately gauge the scalability of a platform (CISCO UCS in this case) when deployed in an RDS scenario

Storage Characterization

View Planner can also be used to characterize storage array performance. The scalability of View Planner 3.5 to drive a workload on thousands of virtual desktops and process the results thereafter makes it an ideal candidate to validate storage array performance at scale. The results below demonstrate scalability of VDI desktops obtained on Pure Storage FA-420 all-flash array. View Planner 3.5 could easily scale to 3000 desktops, as highlighted in the results below.

Custom Applications Scaling

In addition to characterizing platform and storage arrays, the custom app framework can achieve targeted VDI characterization that is application specific. The following results show Visio as an example of a custom app scale study on an RDS deployment with a 4-vCPU, 10GB vRAM Windows 2008 Server.

Other Use Cases

With a plethora of features, supported guest OSes, and configurations, it is no wonder that View Planner is capable to of characterizing multiple VMware solutions and offerings that work in tandem with VMware Horizon. View Planner 3.5 can also be used to evaluate the following features, which are described in more detail in the whitepaper:

  • VMware Virtual SAN
  • VMware Horizon Mirage
  • VMware App Volumes

A whitepaper on VMware Horizon 6 RDSH Performance and Best Practices

2 Replies

VMware Horizon 6 delivers remote desktops and applications from a single platform. With Horizon 6, IT can deliver seamless applications and users can access their desktops or applications from anywhere on devices running Windows, Linux, MAC, iOS, and Android operating systems.

In this blog, we present the Horizon 6 RDSH Performance whitepaper that shows the performance of remote sessions (desktops and seamless applications) and the performance of the RDSH virtual machines, paying particular attention to the sizing of the Horizon 6 environment. The paper also reveals the competitive results of leading remote display network protocols. Finally, the paper presents some of the best practices to tune the RDSH server VM performance. All performance tests were run using the VMware View Planner 3.5 benchmark.

The setup, detailed results, and best practices can be found in the performance whitepaper provided below:

VMware vCenter Server Performance and Best Practices for vSphere 4.1

Leave a reply

VMware recently released a white paper on
performance and best practices for vCenter Server in VMware vSphere 4.1. This
paper addresses four common areas of concerns regarding vCenter Server
performance:

  • Performance improvements in vSphere 4.1 compared to vSphere 4.0
  • vCenter Server sizing guidelines and software requirements
  • Best practices in performance monitoring, tuning and troubleshooting
  • Case studies demonstrating performance improvements in vSphere 4.1.

The vCenter Server in vSphere 4.1 supports a larger
inventory in a vSphere environment when compared with that supported in vSphere
4.0, both at the vCenter Server level and at the single cluster level. A table
is provided in the white paper to show the new supported limits. In addition,
in vSphere 4.1, vCenter Server can handle a larger number of concurrent tasks
at a time when compared with vSphere 4.0.

Significant performance improvements have been made in vSphere
4.1 compared to vSphere 4.0. The following list highlights some of the most
important performance improvements:

  • Improved performance at higher vCenter Server inventory limits – up to 7 times higher operational throughput and up to 75% reduced operational
    latency
  • Improved performance at higher cluster inventory limits – up to 3
    times higher operational throughput and up to 60% reduced operational latency
  • Faster vCenter Server startup – around 5 minutes for maximum
    vCenter Server inventory size
  • Better vSphere Client responsiveness, quicker user interaction,
    and faster user login
  • Faster host operations and VM operations on standalone hosts – up
    to 60% reduction in latency
  • Lower resource usage by vCenter agents by up to 40%
  • Reduced VM group power-on latency by up to 25%
  • Faster VM recovery with HA – up to 60% reduction in total
    recovery time for 1.6 times more VMs
  • Better load balancing with improved DRS/DPM algorithm
    effectiveness
