...................................................................................................62 1 INTRODUCTION Storage administrators VDI administrators Network administrators Virtual machine configuration administrators 1.1 EXECUTIVE SUMMARY NetApp® technology enables companies to extend their virtual infrastructures to include the benefits of advanced storage virtualization. Our unified storage platforms offer industry-leading technologies in the areas of storage efficiencies, instantaneous virtual machine (VM) and data store cloning for virtual servers and virtual desktops, and virtual data center backup and business continuance solutions. This technical report reviews the best practices for implementing a virtual desktop infrastructure (VDI) with Microsoft® Hyper-V™ and Citrix XenDesktop with NetApp unified storage arrays. NetApp has been providing advanced storage features to Microsoft virtualization solutions since 2004. During this time, NetApp has developed operational guidelines for storage arrays running Data ONTAP® and Hyper-V servers. These techniques, which are described in this report, have been documented and are referred to as “best practices.” 1.2 IMPLEMENTING BEST PRACTICES Unless stated otherwise, the recommendations and best practices presented in this document should be considered as deployment requirements. NetApp, Microsoft, and Citrix will still provide support even if you do not implement all of these best practices. However, disregarding any of these practices commonly results in the need to implement them at a later date, in a much larger environment, and often with application downtime. For these reasons, NetApp recommends implementing all of the best practices defined in this document as a part of your initial deployment or migration. All recommendations in this document apply specifically to deploying Microsoft Hyper-V and Citrix XenDesktop on NetApp. Therefore this document supersedes all recommendations and best practices described in other NetApp documents. NetApp and our partners offer professional services to architect and deploy the designs described in this document. These services can provide optimal virtual storage architecture for your virtual data center. 1.3 AUDIENCE This best practice document is part of the NetApp Technical Library and is intended for use by individuals who are responsible for architecting, designing, managing, and supporting Microsoft virtual infrastructures. Readers should, at a minimum, be familiar with concepts pertaining to Microsoft Hyper-V, Citrix XenDesktop, and NetApp Data ONTAP 8. The administrative roles required to implement the technology and/or configurations are presented at the beginning of each section. 1.4 DOCUMENT ROADMAP This technical report is the main document in a set of NetApp documents covering virtualization on NetApp with Microsoft and Citrix products. This document specifically discusses Hyper-V and XenDesktop. 2 NETAPP STORAGE BEST PRACTICES This section applies to: Storage administrators VDI administrators 2.1 AN INTRODUCTION TO STORAGE IN A VIRTUAL INFRASTRUCTURE In a Hyper-V environment, the availability and performance of the shared storage infrastructure are more critical than those of the individual servers running the virtualized server environment. It is therefore vital to factor in the required level of availability and performance when selecting and designing the storage solution for the virtualized server environment. NetApp offers a comprehensive set of software and hardware solutions to address the most stringent requirements for availability and performance of large, scalable Hyper-V environments. 2.2 THE VALUE OF MULTIPROTOCOL STORAGE ARRAYS The virtualization of a data center results in physical systems being virtualized as part of a cost-saving effort to reduce both capital expenditures and operational expenditures through infrastructure consolidation and increased operational efficiencies. These efforts result in multiple VMs sharing physical resources, including shared storage pools known as datastores. Virtualizing demanding, business-critical applications such as e-mail or database servers results in gains in operational efficiencies. Database Servers might share server resources but are typically configured with exclusive access to the storage it requires. Both Microsoft and NetApp offer technologies that natively support multiple storage protocols. These technologies allow customers to deploy best-in-class virtual data centers that leverage the strengths inherent in using these technologies together. This report goes beyond comparing storage area network (SAN) with network-attached storage (NAS) to consider the operational value based on the

  • Windows NT Network Management: Reducing Total Cost of Ownership - 9 - Performance Monitoring
    Windows NT ...: Reducing Total Cost of Ownership - Chapter 9 - Performance Monitorin Page 1 of 13 [Figures are not included in this sample chapter] Windows NT Network Management: Reducing Total Cost of Ownership - 9 - Performance Monitoring AN OLD ADAGE SAYS, "IF YOU can’t measure it, you can’t manage it." Even if you can measure something, how can you tell if your changes are making a difference if you don’t have baseline information? It’s important to monitor a server’s or work- station’s performance to maximize your investment in these tools. If a user complains that her computer is too slow, you often need more information to fix the problem. For example, if the problem is loading Web pages on a computer using an analog modem, the modem is probably limiting the system’s performance. However, if the computer is an older model, certain operations may wait for the CPU to finish processing. In this case, a complete system upgrade may be the best solution. The usefulness of performance monitoring goes far beyond handling user expectations. A network and systems administrator can use information obtained by analyzing the operations of existing hardware, software, and networking devices to predict the timing of upgrades, justify the cost of replacing and upgrading devices, and assist in troubleshooting. Performance monitoring ultimately reduces TCO and is a vital part of managing any IT environment. Performance monitoring helps answer important questions about your current environment. For example, you may want to know which activity specifically uses the most resources in your environment. If you determine that it is loading Web pages, then upgrading the RAM or the CPU speed of client machines may not help much.

  • Building a Template for VDI in the 20'S
    Building a Template for VDI in the 20’s White Paper Introduction In this whitepaper, we will try and dispel some of the art involved in VDI and turn it back into a science. It’s all about the Template - the very heart of your VDI deployment. Whether you are focused on Healthcare, Manufacturing, Education, or any other industry, the IT used to power your business is often a "behind the scenes" resource that users do not directly interact with. For example, Active Directory just runs and there are numerous ways to make it redundant. Should a single server fail, the impact to the end-user is unnoticeable. VDI is the exception to this. If you get the Template wrong in VDI, the effect is immediately felt by the end- user. Choose the wrong amount of memory, and applications will perform poorly. Over optimize the desktop and it will be fast, but users won’t like to use the platform you are delivering – it could be as simple as they don’t have their desktop wallpaper. IT is now scrutinized by the most critical of judges, the end-user and the perception of the end-user community will make or break your VDI role out. There are loads of papers out there that tell you what to do. This paper will focus on the WHY. We have worked on countless VDI deployments and have seen templates done well and templates that can bring users screaming to your door. The WHY behind optimization will help you to create a Template that works for you organization.
