  • RDS Hardware Sizing and Capacity Planning Guidance.

     

    We always felt the need of Hardware capacity guidance and sizing information for Terminal Services or Remote Desktop services for Server 2008 R2, Whenever I am engaged in any architectural guidance discussion for RDS deployment i always get a question what needs to be taken into consideration while deciding the hardware configuration and to do capacity planning.

    Here are some bullet points which I recommend to my partners and customers to consider:

    • 2GB Memory (RAM) is the optimum limit for each core of a CPU. E.g. If you have 4 GB RAM then for optimum performance there should be Dual core CPU.
    • 2 Dual Core CPU perform better then single Quad core processor.
    • Recommended bandwidth for LAN of 30 users and WAN of 20 users.  Bandwidth (b) = 100 megabits per second (Mbps) with Latency (l) Less than 5 milliseconds.
    • On a Terminal Server 64 MB per user is the Ideal Memory (RAM) requirement for GP Only use + 2 GB for OS E.g. (100 users * 64) + 2000 = 8.4 GB i.e. 8GB RAM.
    • More applications used (i.e. Office, CAD Apps and etc.) will require more memory per user to be added to this calculation over the 64 MB base memory per user.
    • 15 TS session per CPU core is the optimum performance limit of a Terminal Server.
    • Network should not have more than 5 hops, and latency should be under 100ms.
    • 64 kbps is the Ideal Bandwidth per user session. (256 color, switched network, bitmap caching only)
    • CPU performance degrades if %processor time per core is constantly above 65%.
    • Terminal servers performance doubles when it is running on a X64 HW and OS.

    In addition to that, Microsoft has just released a whitepaper on Capacity Planning in Windows Server 2008 R2.

    Download it here

    The Remote Desktop Session Host (RD Session Host) role service lets multiple concurrent users run Windows®-based applications on a remote computer running Windows Server® 2008 R2. This white paper is intended as a guide for capacity planning of RD Session Host in Windows Server 2008 R2. It describes the most relevant factors that influence the capacity of a given deployment, methodologies to evaluate capacity for specific deployments, and a set of experimental results for different combinations of usage scenarios and hardware configurations.

    You can also use this document for sizing Terminal Services on a Hyper V Platform

    Also use the Remote Desktop Load Simulation Tools available at following link to do the load testing for number of users on RDS Server

    I hope it helps, Let me know if you have any questions.

    Cheers..

  • Hyper V Live Migration Network Configuration Guide: Now Available

    image               image

     

    If you are following my blog, couple of weeks before i posted a blog post on Live Migration Network configuration. Now its time to learn the official way to configure the Live Migration network.

    Microsoft has just released Hyper-V: Live Migration Network Configuration Guide.

    This guide describes how to configure your network to use the live migration feature of Hyper-V™. It provides a detailed list of the networking configuration requirements for optimal performance and reliability, as well as recommendations for scenarios that do not meet these requirements.

    Some of the common questions which are answered in this guide are:

    • “How Many Network Cards do I needs in my host?”
    • “What if my host has 2 NICs, 3NICs, 4NICs, more?”
    • “What network traffic should I consolidate if I have limited NICs?”
    • “Are the recommendations different if I have 1Gbps NICs or 10Gbps?”
    • Etc.

    It also talks about Hyper-V live migration network requirements, Identifying the network access needs for live migration and Networking considerations for live migration.

    We 'have always felt the need of this kind of best practices document on how to setup a live Migration network which can help in efficient and effective live Migrations in Hyper V Clusters. This document should now help us to get there and design the best Virtual Machine. infrastructure.

    Access it here

    If you wish to learn more about Microsoft Hyper V R2 Live Migration, Please download the Hyper-V Live Migration Overview & Architecture whitepaper

    This document describes the live migration feature of Windows Server® 2008 R2 Hyper-V™ in detail, including how live migration moves running VMs and requirements for implementing live migration.

    Hope it helps for now.

    As always do send your comments, feedback and suggestions :)

    Cheers.

  • Microsoft VDI with Citrix XenDesktop : Virtual Lab Now Available

    image 

    Microsoft® VDI   

     

     

    Microsoft has just released Virtual Lab for Implementing Citrix XenDesktop 4 on Hyper V R2.

    This lab is intended for IT Professionals who would like to deliver virtual desktop computers using Microsoft Hyper-V Server, Microsoft System Center Virtual Machine Manager and Citrix XenDesktop.

    Users will work through the steps to simulate deploying multiple virtual desktops, and will first capture a reference image using the Citrix Provisioning Server for Desktops. Next, the user will verify that the computer can be booted from a diskless client computer. The user will create multiple virtual machines using the reference computer as a template.

    Finally, the user will use the Citrix Desktop Delivery Controller and System Center Virtual Machine Manager to create a group of virtual desktops and deploy them to end devices. At the end of this lab, the user will have worked through all the steps required to implement Citrix XenDesktop using Microsoft System Center Virtual Machine Manager and Microsoft Hyper-V Server.
