PurposeThis document describes the Solution Architecture for VMware View 4.5 for managing virtual desktops on theVblock Infrastructure Platform and specifically the Vblock Series 700 MX.AudienceThis document is intended for use by sales engineers, field consultants, advanced services specialists, andcustomers who will configure and deploy a virtual desktop solution, which centralizes data and applications toprovide desktops as a managed service.ScopeThis document provides an overview of a VMware View 4.5 solution on the Vblock 700. Enterprises which havevarious types of users such as knowledge workers, task workers and power users, are planning, testing, andtransitioning from a physical desktop/laptop to a virtual desktop environment. The workload characteristics of eachof the users in an enterprise environment differ. The IO profiles required for virtual desktops vary, based on thetype of user, type of use, and types of applications installed onto the virtual desktop. Task workers generateworkloads that tend to be network centric whereas knowledge workers and power users generate workloads thatexercise the compute and storage components of the infrastructure supporting the virtual desktop environment.This Solution Architecture (SA) explores a virtual desktop solution designed for Knowledge Workers, and buildson a previously written Solution Architecture (SA) entitled Vblock Powered Solutions for VMware View 4.5Reference Architecture. The previous SA was based on the Vblock 1U, and examined a virtual desktop solutionbuilt for high-end Task Users. Both the previous SA and this architecture utilize and test the B200 M2 blades aspart of the UCS compute, within the Vblock platform.The following aspects are addressed within this SA: An architectural overview Performance validation results Descriptions of the hardware and software components used in the configurations for the compute,storage, network, and virtualization pieces of the solution Information for configuring a Vblock Series 700 for deploying VMware View 4.5Solution purposeThe VMware View Solution on the Vblock 700 allows: Consolidation of the desktop environment into one infrastructure behind the firewall, making it easy toupdate the operating system, patch applications, ensure compliance, perform application migrations, andprovide support from a central location. The Solution delivers a consistent user experience for employees,whether they are at corporate locations, conducting travel, or located at a remote office. Using thissolution, less time is spent reacting to regulatory compliance and security issues and more time addingvalue to the business. 2011 VCE Company, LLC. All rights reserved. 4 5. A simplified desktop environment with pre-integrated, validated units of infrastructure providing virtualizedcompute, network, and storage resources. With validated configurations, one can significantly reduce thetime spent on test and development, and therefore time to production, and to revenue generation, isaccelerated.VCE has built integrated, validated infrastructure packages called Vblock platforms, built from best-of-classcomponents for compute, network, storage and virtualization, from Cisco, EMC and VMware. These platformsallow for massive consolidation and rapid provisioning of compute, network, and storage resources on an on-demand basis.Business ChallengeThe challenges related to traditional desktop deployment and day to day administration, include, lost laptopscontaining corporate data, security breaches related to viruses or hackers, to simply ensuring IT resources canmaintain the required service level agreements (SLAs). In addition to the challenges of operational management,IT must also consider implications of broader system wide issues such as compliance, corporate governance, andbusiness continuity strategies.Technology SolutionEnterprises are turning to virtual desktop technologies to address the operational and strategic issues related totraditional corporate desktop environments. VMware View provides a virtual desktop environment that is secure,cost effective, and easy to deploy. VMware View also has the capability to meet the demanding needs of thedifferent types of user profiles whether on the corporate LAN or on the WAN. Combining VMware with the Vblockplatform ensures a high level of user experience, which in turn means acceptance of the virtual desktopdeployment within organizations. 2011 VCE Company, LLC.

Solution ArchitectureIntroductionIndividual laptops and desktops are managed as standalone entities residing outside of the datacenterenvironment and are not always subject to an organizations information security, backup and recovery, andapplication usage policies. As enterprises and IT organizations require more secure and efficient means formanaging corporate resources, the need to bring all of these resources under the control of a centralizeddatacenter managed by IT becomes of paramount importance. VMware View and Vblock technologies both offerthe capabilities for a centralized datacenter managed by IT. This Solution Architecture (SA) has been designed asa low impact, cost-effective approach to bring all of these resources under the control of the data center usingVMware, Cisco, and EMC technologies, while providing a rich, single view of an end-users applications and data.The SA explores how a multi user desktop environment can be virtualized using VMware View, the Vblockplatforms and provides a template that can be used to implement virtual desktop deployments. We present ourfindings on the number of desktops that can be scaled with a fully populated Vblock 700, as well as the impact onuser experience, within a virtualized desktop environment.Vblock Series 700 MX Infrastructure PlatformThe building blocks of a Vblock 700 comprise core technologies that together provide template-basedvirtualization. Using template-based virtualization to allocate and provision resources, an enterprise can: Reduce performance bottlenecks and configuration errors through automation of resource configurationtasks Enable the rapid deployment of resources using a template, thereby reducing operational expenses andcosts.Ciscos Unified Computing System is the backbone of the virtual infrastructure, providing a data centerarchitecture for administrators that is easy to use and manage. The platform, optimized for virtual environments, isdesigned with open industry standard technologies and aims to reduce TCO and increase business agility. Thesystem integrates a low-latency, lossless 10 Gigabit Ethernet unified network fabric with enterprise-class, x86-architecture servers. The system is an integrated, scalable, multi-chassis platform in which all resourcesparticipate in a unified management domain. The Vblock platforms support the B200, B230, the B250 and theB400 blades in a chassis. The right choice of blade is dependent on CPU and memory requirements of theapplications hosted on the system.EMCs Symmetrix VMAX and infrastructure technologies provide administrators with the tools to manage andmaintain each end users data and applications in the virtual desktop infrastructure. Using the Symmetrix VMAXstorage array and a host of best-of-breed software applications, administrators have a comprehensive set ofsolutions to maintain administrative and security policies. Users of the Symmetrix VMAX will benefit from provenVMAX 99.999 percent availability and innovative technologies like Enterprise Flash drives, Fully AutomatedStorage Tiering (FAST) and Virtual Provisioning. The virtual matrix architecture of the VMAX provides bothscalability and resiliency by ensuring that there is no single point of failure when a component fails.VMwares vSphere 4.1 provides the cloud operating system. The Vblock 700 converged infrastructure adopts theESXi Hypervisor Architecture. ESXi has an ultra thin footprint and sets a new bar for security and reliability. Withnew memory management and expanded resource pooling capabilities, VMware vSphere 4.1 accelerate theevolution of datacenters and service providers into cloud computing environments.PowerPath V/E is included for intelligent path routing and optimized load balancing across all Vblock platforms.EMC PowerPath/VE enables customers to improve performance, and simplify, standardize and automate pathmanagement across physical and virtual environments. 2011 VCE Company, LLC.

The Vblock Series 700 and VMware View 4.5 Solution ArchitectureVMware View 4.5 ArchitectureUsing VMware Views virtual desktop infrastructure technologies, which include VMware View Managersadministrative interface, desktops can be quickly and easily provisioned using templates. The technology permitsrapid creation of virtual desktop images from one master image, enabling administrative policies to be set, andpatches and updates applied to virtual desktops in minutes, without affecting user settings, data, or preferences.The VMware View 4.5 key components are: View Connection Server: This acts as the broker for client connections. It authenticates the users throughthe Active Directory and then directs that request to the virtual desktop. View Client: Client software for accessing the virtual desktop, from a Windows PC, a Mac PC, or a tablet.The administrator can configure the client to allow users to select a display protocol such as PcoIP orRDP. View Agent: Enables discovery of the virtual machine used as the template, for virtual desktop creation.Additionally the agent communicates with the View client to provide features such as access to local USBdevices, printing, and monitoring con...</p>
