IntroductionCompanies are under increasing pressure to deliver enterprise applications on hosted virtual desktopswith the user experience and reliability of a conventional physical desktop. Customers are eager to find asolution that addresses the major pain points of a virtual desktop infrastructure (VDI) deployment—scalability, ease of management, elasticity, and performance. Hyper-converged infrastructure providesthe flexibility and agility demanded by constantly growing VDI environments while reducing thecomplexity.

VxRack™ System 1000 FLEX is a hyper-converged offering that complements VCE convergedinfrastructure systems. These self-contained units of servers and networking are well suited for VDIimplementations. Using EMC ScaleIO technology, VxRack FLEX virtualizes server direct-attachedstorage to create a shared network storage that is similar to traditional SAN storage. This makes it simpleand easy to achieve extreme scale—up to thousands of nodes. VxRack FLEX supports VMware ESXi 6.0today with alternative hypervisors to follow. Bare metal workloads are supported also.

VxRack FLEX is a turnkey system that is pre-assembled and pre-configured according to a VCE ReleaseCertification Matrix (RCM). The RCM reflects extensive pre-testing of hardware, firmware, and software atspecific levels of revision.

VCE provides an enterprise-class end-user computing solution for larger enterprises with the Vblock®

System 540. The scalability offered by VxRack FLEX makes it ideal for enterprises seeking solutionssuited to initially small-scale VDI deployments but with the flexibility to add capacity virtually endlessly.

This whitepaper provides an overview of VxRack FLEX, discusses the benefits of using the system foryour VDI environment, and presents best practices for deploying VMware Horizon 6.2 with View onVxRack FLEX.



Key highlightsVCE conducted an in-depth evaluation of a 1000-user VMware Horizon 6.2 with View environment onVxRack™ System 1000 FLEX using a Power worker workload.

Note: Multiple combinations of VxRack FLEX nodes are available. The results documented in this paperare only true for the specific combination used in the evaluation described in Evaluationenvironment. Results will differ depending on the specific VxRack FLEX configuration.

The following diagram shows the logical layout of VxRack FLEX systems components:

Figure 2: VxRack FLEX system components

ArchitectureVxRack™ System 1000 FLEX is deployed as a quarter, half, or full cabinet system scalable to thousandsof nodes. The minimum configuration is three enclosures, each enclosure containing either one node orfour nodes. You can add enclosures in quarter, half, and full cabinet increments, as required, up to anunlimited number of enclosures.

Enclosures are of the following types:

• Dense Compute—contains four nodes and VMware ESXi hypervisor

• Dense Storage—contains one node and VMware ESXi hypervisor

• Storage Only—contains one node and Red Hat Enterprise Linux

You can mix enclosures of different types in a cabinet, scaling a system in small increments and varyingthe enclosure types in any addition. You can add, relocate, and remove nodes easily. Nodes come withvarious combinations of SSD or SAS drives or both, and some support host cache. For example, a DenseCompute enclosure can provide up to 2 TB of memory and 20 TB of storage. A Dense Storage enclosurecan support 5 TB of SSD drives and more than 20 TB of SAS drives with 512 GB of memory.



EMC ScaleIOVxRack™ System 1000 FLEX utilizes EMC ScaleIO, software that creates a virtual Storage Area Network(SAN) from existing hosts and their local storage. EMC ScaleIO provides elastic, high-performance, highlyscalable, self-healing storage that addresses the main challenges of VDI deployments.

EMC ScaleIO combines hard disk drives, solid-state drives, and Peripheral Component InterconnectExpress (PCIe) flash drives to create a virtual pool of block storage, and then aligns storage availabilitywith application requirements as the need arises. Without a traditional storage array, operations are muchsimpler and costs for cooling and power are much lower. EMC ScaleIO also provides multi-tenantcapabilities and enterprise features such as Quality of Service (QoS), thin provisioning, and snapshots.

EMC ScaleIO enables you to successfully tackle the four challenges that stand between you and aneconomically viable VDI deployment:

• Storage costs

Storage typically makes up a significant portion of the cost of application deployments such asVDI. With EMC ScaleIO, you "pay as you grow" and therefore you do not need to pre-pay forinfrastructure you may not need. EMC ScaleIO is a server-based SAN, and there are nodedicated storage components such as FC switches and HBAs. With EMC ScaleIO, compute andstorage resources are converged, maximizing local storage and simplifying management. EMCScaleIO Data Server (SDS) accesses storage volumes on the application hosts by means of theVirtual Machine File System (VMFS) and EMC ScaleIO Data Client (SDC) exposes volumes asiSCSI targets to the VMFS.

• Elasticity

VDI projects often start small and then grow quickly into many hypervisor servers. Providing theright size of SAN for each stage of this growth presents challenges in dynamically growing scale-out storage. Storage and compute resources can be added to or removed from the EMC ScaleIOcluster as needed, with no downtime and minimal impact to application performance.

• Performance

Running large numbers of virtual desktops per hypervisor requires storage that can sharecapacity across physical servers and reallocate performance to the relevant servers as needed.The self-healing, auto-balancing capability of the EMC ScaleIO cluster ensures that data isautomatically rebuilt and re-balanced across resources when components are added, removed,or failed. Because every server and local storage device in the cluster is used in parallel toprocess I/O operations and protect data, system performance scales linearly as additional serversand storage devices are added to the configuration.

• Management

Simplifying IT operations and management is often one of the main VDI deployment objectives.The storage selected should support this objective, reducing labor-intensive storage tasks to aminimum.



The following diagram is an example of the logical layout of EMC ScaleIO on VxRack FLEX:

NetworkingIndustry-standard Cisco Nexus Top of Rack (ToR) and Spine switches in the network layer provide 10GbE and 40 GbE IP connectivity between VxRack™ System 1000 FLEX and the external network.

VxRack FLEX includes the following switches:

• One Cisco Nexus 3172TQ for out-of-band management

• One pair of Cisco Nexus 3132Q-X/3164Q ToR switches

• One pair of Cisco Nexus 9332PQ leaf/aggregation switches



The following diagram illustrates the network topology for VxRack FLEX.

VxRack™ System management softwareVxRack System management software is a bundle that includes VCE Vision™ VxRack™ Manager andVCE Vision™ Intelligent Operations.

VCE Vision™ VxRack Manager is a hyper-converged infrastructure management tool. It provides aunified management user interface for all VCE hyper-converged systems. VxRack System Administratorsuse this interface to perform their day-to-day operations-from viewing inventory, monitoring system healthand performance, and obtaining RCM guidance-to bootstrapping new nodes and performing logicalsystem management to partition resources.

VCE Vision™ VxRack Manager consists of a graphical user interface (GUI) and hardware managementsystem (HMS) that is used by the VxRack System Administrator. VCE Vision software provides a full viewof the data center that is used by the Data Center Administrator.

VirtualizationVxRack™ System 1000 FLEX supports virtualization-based hypervisors and non-virtualized operatingsystems for bare-metal workloads.

In VxRack FLEX, VMware vSphere provides virtualization services. The core VMware vSpherecomponents are the VMware vSphere ESXi and VMware vCenter Server for management.

VMware vCenter Server 6.0 simplifies planning and deployment by offering two deployment models. Thefirst, embedded, deploys the new Platform Services Controller (PSC) and the vCenter Server instance onthe same machine. The second, external, deploys the PSC and the vCenter Server instance on separatemachines.

You can also deploy a vCenter Server Appliance, which contains all of the necessary services for runningvCenter Server 6.0 along with its components, as an alternative to installing vCenter Server on aWindows host machine.

The hypervisors are deployed in a cluster configuration. The cluster allows dynamic allocation ofresources, such as CPU, memory, and storage. The cluster also provides workload mobility and flexibilitywith the use of VMware vMotion and Storage vMotion technology.



Virtual Desktop InfrastructureVirtual desktop infrastructure (VDI) allows organizations to nimbly and cost-effectively support a mobileworkforce while extending the efficiency of server virtualization to the desktop environment.

VxRack™ System 1000 FLEX enables enterprises to roll out VDI for departments or locations at a fractionof the cost of a traditional server environment. You can start small without overspending on hardware anduse a pay-as-you-grow model when adding extra desktops, additional components, or models that aremore powerful. With VxRack FLEX, you can seamlessly scale to hundreds of virtual desktops whiledelivering a great user experience without sacrificing performance or scale.

VCE evaluations have shown that VxRack FLEX with one Dense Compute enclosure and two DenseStorage enclosures can support more than 750 VMware Horizon View Linked-Clone virtual desktops atthe same time. This mix provides compute and storage for the desktops and user profile data, leavingplenty of space for user data.

Note: Multiple combinations of VxRack FLEX nodes are available. The results documented in this paperare only true for the specific combination used in the evaluation described in Evaluationenvironment. Results will differ depending on the specific VxRack FLEX configuration.

Storage is likely to be a make-or-break component of any VDI project because of the followingchallenges:

• Designing the infrastructure for scale-out capacity

• Delivering adequate, stable performance for desktop users

VxRack FLEX uses EMC ScaleIO software-defined storage to address the complexity of storage in a VDIenvironment. A Dense Storage or Storage Only enclosure can be used to extend the EMC ScaleIOcluster and the data stores in the ESXi environment easily. The virtual desktops can then be recomposedto utilize the new storage.

EMC ScaleIO provides the option of creating separate SAS and SSD pools, which greatly enhancesperformance by storing Replicas in the SSD pool and Linked Clones on the SAS pools. The impact of I/Ostorms is greatly reduced. EMC ScaleIO is easy to deploy and manage. It uses the directly attachedstorage and compute components of VxRack FLEX to deliver massively parallel performance, whileproviding stable bandwidth and IOPs rates even during high demand operations.

Why run View on VxRack™ System 1000 FLEX?The primary benefits of hyper-converged infrastructure for VDI implementations are scalability, flexibility,reduced hardware-related complications, and simplified management and operations.

Scalability

Many VCE customers do not want to create pervasive silos of infrastructure that are prescriptivelytargeted for specific applications. They want the ability to flexibly scale deployments to meet the evolvingrequirements of their user community.

VxRack FLEX gives you the flexibility to design and implement a VDI environment based on applicationneeds, budget, and growth. Start with the right-size deployment to meet today's demands, and scale up toweb scale.

VxRack FLEX uses EMC ScaleIO technology to enable scaling from a quarter cabinet of compute andstorage nodes to very large-scale deployments-greater than 1,000 nodes. This enables a quickturnaround from a Proof of Concept (POC) unit to a full-fledged enterprise environment with minimaldisruption.

Flexibility

With VxRack FLEX, customers can start small with a quarter or half cabinet system and grow to datacenter scale in flexible, discrete increments. If you need to grow storage, VxRack FLEX offers StorageOnly nodes to accommodate non-linear storage growth. In addition, you can make granular upgrades tooptimize VDI operations.

Hardware

Administrators typically put a lot of effort into hardware selection, capacity planning, and hardware tuning.VxRack FLEX is a software-based architecture with integrated compute, software-defined storage,networking, and virtualization. It enables compute, storage, and networking functions to be decoupledfrom the underlying infrastructure and run on a common set of physical resources that are based onindustry-standard x86 components. VxRack FLEX minimizes the physical data center footprint andcollapses the traditional 3-tier legacy infrastructure into one easy-to-manage solution.

Simplified management and operations

VCE Vision™ VxRack™ Manager provides a unified and persona-based user experience to deploy,monitor, sustain and support VxRack FLEX. It provides Administrators and Users a centralized dashboardfrom which they can perform various operations such as the following:

• Add nodes to the system

• Get current status including RCM guidance

• Update various components for RCM compliance

• Generate system logs for VCE™ Support



VCE Vision software simplifies operations by providing a consistent, common view of all converged andhyper-converged infrastructure connected to VCE™ Fabric. Information about VxRack FLEX appears withinformation about other VCE systems.

Using application program interfaces (APIs) with the management and orchestration tools of their choice,customers can access expanded data and gain key intelligence at the data center level such as systemhealth scores, RCM data, and performance thresholds and indicators.

The following diagram illustrates the logical layout of the VDI components on the VxRack FLEX:

Figure 5: Logical layout of VDI components

Evaluation methodology

We used LoginVSI to test performance by simulating user workloads with realistic user behavior. LoginVSI is an industry-standard tool designed to measure the maximum capacity of VDI infrastructures bysimulating unique user workloads. The simulated users work with the same applications as typicalemployees, such as Microsoft Word, Excel, Outlook, and Internet Explorer. The results of several testingmeasurements are compiled into a metric known as VSImax, which quantifies the maximum capacity ofVDI workloads running on a given infrastructure while delivering an acceptable user experience.

We configured LoginVSI to run a pre-defined Power worker workload against a 1000 VMware Horizon 6.2with View desktop configuration. We used a Power worker workload because it consumes more memoryand CPU resources due to the increased number of applications simultaneously running, whichaddresses most hosted virtual desktop user classes.

During testing, Login VSI sessions were initiated by launchers (simulated user endpoints) that ran onseparate compute and storage infrastructure. Fifty launchers were utilized, each running an average of 20sessions. Each launcher was configured with two vCPUs and 8 GB of vRAM, following Login VSI sizingguidelines.



Other test parameters included:

• Workload simulates a power user workload using Office, Internet Explorer, and PDF.

• Once a session has been started, the power user workload repeats every 12 minutes.

• During each loop, the response time is measured every two minutes.

• The power user workload opens up to five applications simultaneously.

• The type rate is 160 ms for each character.

• Approximately two minutes of idle time is included to simulate real-world users.

Evaluation metrics

We measured response times for the following transactions:

Transaction Description

FCTL Copy a local random text file from local temp directory to home drive

FCTS Copy a text document from VSIshare to temp directory

NFO Measure how long it takes to show the file-open dialog in VSI notepad

NFP Print open VSI-Notepad file [ctrl+p]

NSLD VSI-Notepad starts and loads a 1500 KB document that is copied from the content pool

ZHC Compress a local random .pst file that is copied from the content pool (5 MB) using 7zip

ZLC Copy a random file and compress it (with 7zip) with low compression enabled

Evaluation results

Results of the evaluation demonstrated the following:

• One Dense Compute enclosure was able to support up to 550 Linked-Clone virtual desktops

• One Dense Storage enclosure was able to support up to 120 Linked-Clone virtual desktops

• VSIMax was not reached during testing with a 1000 concurrent Power worker workload

Note: Multiple combinations of VxRack FLEX nodes are available. The results documented in this paperare only true for the specific combination used in the evaluation described in this paper. Resultswill differ depending on the specific VxRack FLEX configuration.



Design considerationsWhile the design of a VDI environment on VxRack™ System 1000 FLEX will be specific to the customerenvironment, the following best practices are applicable to all deployments.

Scaling the environment

VCE customers want the ability to scale their VDI deployments flexibly to meet the evolving requirementsof their user community. VxRack FLEX supports flexible, granular scaling by cabinet, enclosure, or node.You can:

• Scale from a quarter cabinet of enclosures to very large-scale deployments—greater than 1,000enclosures.

• Add unlimited Dense Compute enclosures with various CPU, memory, and drive options. OneDense Compute enclosure contains four nodes and supports up to 550 virtual desktops. Eachnode provides up to 2 TB of memory and 20 TB of storage.

• Add unlimited Dense Storage enclosures. A Dense Storage enclosure contains one node thatsupports up to 5 TB of SSD drives and more than 20 TB of SAS drives with 512 GB of memory.Each Dense Storage enclosure supports 120 virtual desktops.

Note: Multiple combinations of nodes are available. The results documented in this paper areonly true for the specific combination used in the evaluation described in Evaluationenvironment. Results will differ depending on the specific VxRack FLEX configuration.

• Add, move, and remove nodes on the fly to extend direct attached storage (DAS) capacityexponentially.

• Add expansion cabinets with additional resources.

• With VCE Vscale™ Architecture, the existing Vblock® Systems and VxBlock™ Systems can alsobe extended.

EMC ScaleIO best practices

We recommend the following best practices for deploying EMC ScaleIO on VxRack FLEX:

• In general, follow EMC best practices for deployment and configuration of EMC ScaleIO in yourspecific environment. Refer to support.emc.com for additional information about EMC ScaleIO.

• To provide consistent performance, we recommend that all devices in the EMC ScaleIO storagepool have similar storage properties. While mixing different types and sizes of media in the samestorage pool is allowed, performance will be limited to the least-performing and smallest-sizedmember of the storage pool due to data distribution.

• A Storage Only node has very limited computing power so should not be used for runningapplication virtual machines.



inhttps://support.emc.com/

• To provide the best EMC ScaleIO and networking performance, configure Jumbo Frames (9000MTU) across all switches, network devices, and servers.

• If you expand storage by adding an extra node:

1 Add the node to the proper EMC ScaleIO storage pool.

2 Wait for rebalancing tasks to complete.

3 Create necessary datastores.

4 Recompose the virtual desktops to take advantage of the new storage.

• Since EMC ScaleIO does not provide automatic storage tiering, where active data is migrated tohigh–performance SSD pools and inactive data to SAS pools, monitor datastore performance toensure proper placement of virtual disks.

• Each ESXi host must run the EMC ScaleIO virtual machine. After ESXi installation and EMCScaleIO virtual machine setup, not much space is left on the SATADOM. Redirect the hostsystem logs to a central syslog server so that the SATADOM disk is not overrun with log files.

General best practices

Based on initial evaluation results, we recommend the following best practices for deploying VDIenvironments on VxRack FLEX:

• Follow general VMware Horizon 6.2 with View best practices for virtual machine configuration andoptimization, gold image build, and server sizing guidelines. Refer to vmware.com/support/pubs/view_pubs.html for additional information.

• Consult the VCE Professional Services to correctly estimate the size of the required environment.Because VxRack FLEX provides fast and easy scalability, avoid overestimating initial computeand storage requirements.

• Run application virtual machines on the nodes in the Dense Compute and Dense Storageenclosures only. Storage Only nodes have limited compute and memory and provide storageonly.
