  15. 15. Chapter 1: Executive Summary Planning and designing the storage infrastructure for VMware View is a critical step as the shared storage must be able to absorb large bursts of input/output (I/O) that occur throughout the course of a day. These large I/O bursts can lead to periods of erratic and unpredictable virtual desktop performance. Users can often adapt to slow performance, but unpredictable performance will quickly frustrate them. To provide predictable performance for an EUC environment, the storage must be able to handle peak I/O load from clients without resulting in high response times. Designing for this workload involves deploying several disks to handle brief periods of extreme I/O pressure and it is which is expensive to implement. This solution uses EMC VNX FAST Cache to reduce the number of disks required, and thus minimizes the cost.Key results and recommendations EMC VNX FAST Cache provides measurable benefits in a desktop virtualization environment. It not only reduces the response time for both read and write workloads, but also effectively supports more virtual desktops on fewer drives, and greater IOPS density with a lower drive requirement.

Chapter 3: VMware View Infrastructure3 VMware View Infrastructure This chapter describes the general design and layout instructions that apply to the specific components used during the development of this solution. This chapter includes the following sections:  VMware View 5.0  vSphere 5.0 Infrastructure  Windows infrastructureVMware View 5.0Introduction VMware View delivers rich and personalized virtual desktops as a managed service from a virtualization platform built to deliver the entire desktop, including the operating system, applications, and user data. With VMware View 5.0, administrators can virtualize the operating system, applications, user data, and deliver modern desktops to end users. VMware View 5.0 provides centralized, automated management of these components with increased control and cost savings. VMware View 5.0 also improves business agility while providing a flexible high-performance desktop experience for end users across a variety of network conditions.Deploying VMware This solution used four VMware View Manager Server instances each capable ofView components scaling up to 2,000 virtual desktops. This solution also used four View Manager servers to provide for redundancy if one server was unavailable. Deployments of up to 10,000 virtual desktops are possible by using additional View Manager servers. The core elements of a VMware View 5.0 implementation are:  VMware® View™ Manager Connection Server 5.0  VMware View Composer 2.7  VMware View Persona Management  VMware vSphere 5.0 Additionally, the following components are required to provide the infrastructure for a VMware View 5.0 deployment:  Microsoft Active Directory  Microsoft SQL Server  DNS server  Dynamic Host Configuration Protocol (DHCP) server EMC Infrastructure for VMware View 5.0 EMC VNX Series (NFS), VMware vSphere 5.0, VMware View 5.0, VMware View Persona 23 Management, and VMware View Composer 2.7—Proven Solutions Guide
  24. 24. Chapter 3: VMware View InfrastructureView Manager The View Manager Connection Server is the central management location for virtualServer desktops and has the following key roles:  Broker connections between the users and the virtual desktops  Control the creation and retirement of virtual desktop images  Assign users to desktops  Control the state of the virtual desktops  Control access to the virtual desktopsView Composer 2.7 View Composer 2.7 works directly with vCenter Server to deploy, customize, and maintain the state of the virtual desktops when using linked clones. The tiered storage capabilities of View Composer 2.7 enable the read-only replica and the linked clone disk images to be on dedicated storage. This allows for superior scaling in large configurations. View Composer is installed on each of the three vCenter servers.VMware View VMware View Persona Management is a new feature introduced with VMware ViewPersona 5.0 that preserves user profiles and dynamically synchronizes them with a remoteManagement profile repository. VMware View Persona Management does not require the configuration of Windows roaming profiles, eliminating the need to use Active Directory to manage View user profiles.  The combination of VMware View Persona Management and floating assignment desktop pools provides the experience of a dedicated desktop while potentially minimizing the number of desktops required in an organization.  With VMware View Persona Management, a user’s remote profile is dynamically downloaded when the user logs in to a View desktop. View downloads persona information only when the user needs it.  During login, VMware View Personal Management downloads only the files that Windows requires such as, user registry files. Other files are copied to the local desktop when the user or an application opens them from the local profile folder.  VMware View Persona Management copies recent changes in the local profile to the remote repository at a configurable interval.  During logoff, only files that were updated since the last replication are copied to the remote repository.  VMware View Persona Management can be configured to store user profiles in a secure, centralized repository.Floating Floating assignment desktop pools can reduce the number of desktops required inassignment situations where not all users need to be logged into desktops at the same time. Indesktop pools addition, desktop storage requirements are reduced as a persistent data disk will not be required for each desktop. The combination of VMware View Persona Management and floating assignment desktop pools provides the experience of a dedicated EMC Infrastructure for VMware View 5.0 EMC VNX Series (NFS), VMware vSphere 5.0, VMware View 5.0, VMware View Persona 24 Management, and VMware View Composer 2.7—Proven Solutions Guide

Chapter 3: VMware View Infrastructure desktop while potentially minimizing the number of desktops required in an organization.View Composer VMware View with View Composer uses the concept of linked clones to quicklylinked clones provision virtual desktops. This solution uses the tiered storage feature of View Composer to build linked clones and place their replica images on separate datastores as shown in Figure 2. Figure 2. VMware View—Linked clones The operating system reads all the common data from the read-only replica, and the unique data that is created by the operating system or user. This unique data is stored on the linked clone. A logical representation of this relationship is shown in Figure 3. Figure 3.

  26. 26. Chapter 3: VMware View InfrastructurevSphere 5.0 InfrastructurevSphere 5.0 VMware vSphere 5.0 is the market-leading virtualization hypervisor used acrossoverview thousands of IT environments around the world. VMware vSphere 5.0 can transform or virtualize computer hardware resources, including the CPUs, RAM, hard disks, and network controllers, to create fully functional virtual machines. Each virtual machine runs their own operating systems and applications just like physical computers. The high-availability features in VMware vSphere 5.0 along with VMware Distributed Resource Scheduler (DRS) and Storage vMotion® enable seamless migration of virtual desktops from one vSphere server to another with minimal or no disruption to the customers.Desktop vSphere This solution deploys nine vSphere clusters to host virtual desktops. The desktopclusters vSphere 5.0 clusters consist of two different vSphere 5.0 server configurations. These server types were chosen due to availability. Similar results should be achievable with a variety of server configurations assuming that the ratios of server RAM per desktop and number of desktops per CPU core are upheld.  Cluster Type A consists of three quad deca-core vSphere 5.0 servers to support 741 desktops, each resulting in around 246 to 247 virtual machines per server. Each cluster has access to five NFS datastores; four for storing desktop linked clones and one for storing a desktop replica image.  Cluster Type B consists of five dual hex-core vSphere 5.0 servers to support 463 additional desktops, each resulting in around 92 to 93 virtual machines per vSphere server. Each cluster has access to four NFS datastores; three for storing desktop linked clones and one for storing a desktop replica image.Infrastructure One vSphere cluster is deployed in this solution for hosting the infrastructure servers.vSphere cluster This cluster is not required if the resources needed to host the infrastructure servers are already present within the host environment. The infrastructure vSphere 5.0 cluster consists of three dual hex-core vSphere 5.0 servers. The cluster has access to a single datastore that is used for storing the infrastructure server virtual machines. The infrastructure cluster hosts the following virtual machines:  Two Windows 2008 R2 SP1 domain controllers — Provides DNS, Active Directory, and DHCP services.  Three VMware vCenter 5 Servers each running on Windows 2008 R2 SP1 — Provides management services for the VMware clusters and View Composer. One of these three servers also runs vSphere 5.0 Update Manager.  Four VMware View 5.0 Manager Servers each running on Windows 2008 R2 SP1 — Provides services to manage the virtual desktops.  SQL Server 2008 SP2 on Windows 2008 R2 SP1 — Hosts databases for each of the three VMware Virtual Center Servers and their associated VMware View Composer installations.

Chapter 3: VMware View Infrastructure  Windows 7 Key Management Service (KMS)—Provides a method to activate Windows 7 desktops.Windows infrastructureIntroduction Microsoft Windows provides the infrastructure that is used to support the virtual desktops and includes the following components:  Microsoft Active Directory  Microsoft SQL Server  DNS server  DHCP serverMicrosoft Active The Windows domain controllers run the Active Directory service that provides theDirectory framework to manage and support the virtual desktop environment. Active Directory performs the following functions:  Manages the identities of users and their information  Applies group policy objects  Deploys software and updatesMicrosoft SQL Microsoft SQL Server is a relational database management system (RDBMS). AServer dedicated SQL Server 2008 SP2 is used to provide the required databases to vCenter Server and View Composer.DNS server DNS is the backbone of Active Directory and provides the primary name resolution mechanism for Windows servers and clients. In this solution, the DNS role is enabled on the domain controllers.DHCP server The DHCP server provides the IP address, DNS server name, gateway address, and other information to the virtual desktops. In this solution, the DHCP role is enabled on one of the domain controllers. The DHCP scope is configured with an IP range that is large enough to support 5,000 virtual desktops.

  28. 28. Chapter 4: Storage Design4 Storage Design This chapter describes the storage design that applies to the specific components of this solution.EMC VNX series storage architectureIntroduction The EMC VNX series is a dedicated network server optimized for file and block access that delivers high-end features in a scalable and easy-to-use package. The VNX series delivers a single-box block and file solution that offers a centralized point of management for distributed environments. This makes it possible to dynamically grow, share, and cost-effectively manage multiprotocol file systems and provide multiprotocol block access. Administrators can take advantage of simultaneous support for NFS and CIFS protocols by enabling Windows and Linux/UNIX clients to share files by using the sophisticated file-locking mechanisms of VNX for File and VNX for Block for high-bandwidth or for latency-sensitive applications. This solution uses file-based storage to leverage the benefits that each of the following provides:  File-based storage over the NFS protocol is used to store the VMDK files for all virtual desktops. This has the following benefit:  Unified Storage Management plug-in provides seamless integration with VMware vSphere to simplify the provisioning of datastores or virtual machines.  EMC vSphere Storage APIs for Array Integration (VAAI) plug-in for vSphere 5.0 supports the vSphere 5.0 VAAI primitives for NFS on the EMC VNX platform.  File-based storage over the CIFS protocol is used to store user data and the VMware View Persona Management repository. This has the following benefits:  Redirection of user data and VMware View Persona Management data to a central location for easy backup and administration.  Single instancing and compression of unstructured user data to provide the highest storage utilization and efficiency. This section explains the configuration of the storage provisioned over NFS for the vSphere cluster to store the VMDK images and the storage provisioned over CIFS to redirect user data and provide storage for the VMware View Persona Management repository.

Chapter 4: Storage DesignStorage layout The following configurations are used in the core reference architecture as shown inoverview Figure 4:  Four SAS disks (0_0_0 to 0_0_3) are used for the VNX OE.  Disks 0_0_6, 0_0_7, 4_0_2, and 6_0_4 are hot spares. These disks are denoted as Hot Spares in the storage layout diagram.  Ten Flash drives (0_0_4, 0_0_5, 2_0_0, 2_0_1, 4_0_0, 4_0_1, 6_0_0 to 6_0_3) are used for EMC VNX FAST Cache. There are no user-configurable LUNs on these drives.  Sixty-five SAS disks (0_1_0 to 0_1_14, 2_1_0 to 2_1_14, 4_1_0 to 4_1_14, 6_1_0 to 6_1_14, and 6_0_4 to 6_0_8) in a RAID 5 storage pool (Storage Pool 0) are used to store linked clones and replicas. FAST Cache is enabled for the entire pool. Forty-two NFS file systems are provisioned and presented to the vSphere servers as datastores.

  32. 32. Chapter 4: Storage DesignFile system layout Figure 6 shows the layout of the NFS file systems. Figure 6. VNX7500–NFS file system layout Sixty-five LUNs of 323 GB each are provisioned out of a RAID 5 storage pool configured with 65 SAS drives. Sixty-five drives are used because the block-based storage pool internally creates 4+1 RAID 5 groups. Therefore, the number of SAS drives used is a multiple of five. Likewise, sixty-five LUNs are used because AVM stripes across five dvols; the number of dvols is a multiple of five. The LUNs are presented to VNX File as dvols that belong to a system-defined pool. Forty-two file systems are then provisioned out of an Automatic Volume Management (AVM) system pool and are presented to the vSphere servers as datastores. File systems 1 to 9 are used to store replicas. File systems 20 to 53 are used to store the linked clones. A total of 5,000 desktops are provisioned and each replica is responsible for 741 or 463 linked clones, depending on the server type used in the desktop cluster. Starting from VNX for File version 7.0.35.3, AVM is enhanced to intelligently stripe across dvols that belong to the same block-based storage pool. There is no need to manually create striped volumes and add them to user-defined file-based pools.

  33. 33. Chapter 4: Storage Design Figure 7 shows the layout of the optional CIFS file systems. Figure 7. VNX7500–CIFS file system layout Sixty-five LUNs of 231 GB each are provisioned out of a RAID 6 storage pool configured with 64 NL-SAS-drives. Sixty-four drives are used because the block-based storage pool internally creates 6+2 RAID 6 groups. Therefore, the number of NL-SAS drives used is a multiple of eight. Likewise, sixty-five LUNs are used because AVM stripes across five dvols, so the number of dvols is a multiple of five. The LUNs are presented to VNX File as dvols that belong to a system-defined pool. Like the NFS file systems, the CIFS file systems are provisioned from an AVM system pool to store user home directories and the VMware View Persona Management repository. The two file systems are grouped in the same storage pool because their I/O profiles are sequential. FAST Cache is enabled on both storage pools that are used to store the NFS and CIFS file systems.EMC VNX FAST VNX Fully Automated Storage Tiering (FAST) Cache, a part of the VNX FAST Suite, usesCache Flash drives as an expanded cache layer for the array. VNX7500 is configured with ten 200 GB Flash drives in a RAID 1 configuration for a 916 GB read/write-capable cache. This is the minimum amount of FAST Cache. Larger configurations are supported for scaling beyond 5,000 desktops. FAST Cache is an array-wide feature available for both file and block storage. FAST Cache works by examining 64 KB chunks of data in FAST Cache-enabled objects on the array. Frequently accessed data is copied to the FAST Cache and subsequent accesses to the data chunk are serviced by FAST Cache. This enables immediate promotion of very active data to the Flash drives.

  34. 34. Chapter 4: Storage Design improves the response times for very active data and reduces data hot spots that can occur within the LUN. FAST Cache is an extended read/write cache that enables VMware View to deliver consistent performance at Flash-drive speeds by absorbing read-heavy activities (such as boot storms and antivirus scans), and write-heavy workloads (such as operating systems patches and application updates). This extended read/write cache is an ideal caching mechanism for View Composer because the base desktop image and other active user data are so frequently accessed that the data is serviced directly from the Flash drives without accessing the slower drives at the lower storage tier.VSI for VMware EMC Virtual Storage Integrator (VSI) for VMware vSphere is a plug-in to the vSpherevSphere client that provides a single management interface for managing EMC storage within the vSphere environment. Features can be added and removed from VSI independently, which provides flexibility for customizing VSI user environments. Features are managed by using the VSI Feature Manager. VSI provides a unified user experience that allows new features to be introduced rapidly in response to changing customer requirements. The following VSI features were used during the validation testing:  Storage Viewer (SV)—Extends the vSphere client to facilitate the discovery and identification of EMC VNX storage devices that are allocated to VMware vSphere hosts and virtual machines. SV presents the underlying storage details to the virtual data center administrator, merging the data of several different storage mapping tools into a few seamless vSphere client views.  Unified Storage Management—Simplifies storage administration of the EMC VNX platforms. It enables VMware administrators to provision new NFS and VMFS datastores, and RDM volumes seamlessly within vSphere client. The EMC VSI for VMware product guides available on the EMC online support website provide more information.vCenter Server FS1 to FS9—Each of the 25 GB datastores store a replica that is responsible for eitherstorage layout 741 or 463 linked clone desktops, determined by the vSphere cluster configuration. The input/output to these LUNs is strictly read-only except during operations that require copying a new replica into the datastore. FS20 to FS53—Each of these 600 GB datastores accommodate an average of 152 virtual desktops. This allows each desktop to grow to a maximum average size of approximately 3.9 GB. Each pool of desktops provisioned in View Manager is balanced across either three datastores in each hex-core server cluster, or five datastores in each deca-core server cluster.VNX shared file Virtual desktops use two VNX shared file systems, one for VMware View Personasystems Management data and the other to redirect user storage. Each file system is exported to the environment through a CIFS share.
