VDI on NetApp Virtualized Storage for Virtual Desktop Infrastructure
Forward: This presentation is intended for use by NetApp Direct Sales and Channel Partners, to provide an overview of NetApp’s compelling capabilities in a virtual desktop infrastructure envrionment. This presentation is intended for delivery to an IT Director-level individual, and is most appropriate for a first meeting on the topic. Note that VMware is the market leader in this area and is referenced in several examples, but this pitch is intended to be applicable for customers who are using/considering either VMware or other virtualization solutions (e.g. Microsoft, Xen, etc.) Speaker notes for this slide: Go further, faster, with NetApp. NetApp is an established and recognized leader for Storage Management solutions. Server and desktop virtualization is igniting change in the datacenter, from small to large enterprises and is being widely adopted throughout the industry. Desktop virtualization places new demands on the storage infrastructure that should be considered early in the design process. NetApp provides storage and data management solutions that uniquely enable effective virtualization environments, and which further extend the benefits of desktop virtualization. In this presentation, we’ll review why NetApp is the best choice as your storage solution for virtualized desktop environments.

Traditional Desktop challenges
Management Security Compliance Access/changing workforce Disaster recovery/business continuity The objective of this slide is to establish credibility and show an understanding of the challenges that a desktop operations group faces. Speaker notes for this slide: The traditional enterprise desktop environment has always been challenging. Requirements of management, security, compliance, access, and business continuity are difficult to implement and expensive to deploy. Management: supporting corporate machines and assets day-to-day Security: assuring data and machine security independent of location Compliance: ensuring that machines are compliant with corporate and regulatory requirements Access/changing workforce: providing users “anytime, anywhere” access to data and applications Disaster recovery/business continuity: ensuring continuity in the event of machine loss, disaster, or workforce interruption Forrester Research NetApp Confidential -- Do Not Distribute

VDI Success Criteria and Why Storage is Critical
Low initial capital investment Providing storage for 100s, 1000s of desktops very costly User data often 2-3 times the desktop OS size Simplify and centralize VDI management Managing virtual desktop infrastructure requires agile storage Need to provision VMs and storage for 1000s of desktops Same or better user experience Storage availability and performance are essential Bottlenecks or failures can impact 1000’s of users Storage is central to security and control of user data Require regular backups, data retention and immutable storage The objective of this slide is to articulate why they should care about storage. If your audience have mostly a desktop background, they probably have not really thought about storage for their VDI. Speaker notes for this slide: Key points to stress – Initial storage investment can be massive since desktops have moved from inexpensive local storage to expensive network storage. Do not forget the storage required for user data. VDI environment is a convergence of server, desktops, storage, networking, can introduce new complexities in management. Long latency can be an obstacle to user adoption of VDI. Now that hundreds and thousands of desktops are on the same storage platform, bottlenecks or failures and cause major outage and affect many users instead of just individual users. To fulfilled the compliance promise of VDI, storage is critical to ensure regular backups and taken and retained, recovery is easy and speedy, and for certain environments, immutable storage ensures compliance to external regulatory standards.

Affordable Internet Services Online, Inc. (AISO)
Business Challenge Build high-availability infrastructure for subscription-based hosted virtual desktops Reduce energy consumption to stay 100% solar powered Solution VMware® on NetApp® storage to maximize uptime, conserve space, and shrink energy usage 400+ virtual desktop systems on eight physical servers Benefits Expanded business while staying 100% solar powered Reduced energy use by 70% Protected 24x7 operations with fast backup & recovery Consumed 8X less capacity by using thin provisioning - 40GB, using 5GB Eliminated tape systems (along with cost, space, power/cooling) The country’s first solar-powered hosting company, AISO runs 100% on solar energy Inc. Magazine’s Top 50 Green Companies 15,000 clients, including green-movement notables like Discovery Communications and Google (a consortium site) Organization Overview: Since 1997, Affordable Internet Services Online, Inc. (AISO) has been a trusted name in environmentally friendly Web hosting. Founded as the country’s first solar-powered hosting company, AISO runs 100% on solar energy. As a reliable and responsible green Web-hosting company, AISO strives to deliver world-class customer service while simultaneously protecting and preserving natural resources (source: Challenge: AISO runs all of its mission-critical operations on clean energy derived exclusively from solar panels that power both the AISO data center and business offices. As the company’s customer base expanded, so did its IT infrastructure. The cooling and energy demands of more than 100 servers and storage systems pushed the limits of existing solar arrays. The prospect of continually expanding the solar-powered network to address business needs compelled the AISO team to pursue alternative solutions. The challenge was to meet the company’s Web-hosting requirements—including high performance for responsive services, systems redundancy for maximum uptime, and scalability for continued growth—without fueling a costly upward spiral of energy consumption. Solution: Teamed with NetApp and Sirius Computer Solutions, AISO designed an energy-efficient virtualized infrastructure. Built on IBM BladeCenter servers and NetApp storage, the AISO environment met performance, availability, and scalability requirements. Consolidation of 120 servers resulted in an immediate 60% reduction in power consumption. Using VMware on NetApp serves a global community of more than 15,000 clients, including green-movement notables like Discovery Communications and Google. NetApp provides the storage for all of AISO’s business, including hosting platforms, Web design, financial systems, and other applications. The NetApp FAS3070 system, configured with active-active controllers for highest availability, provides storage resources to 400+ virtual desktop systems running on eight physical servers communicating by NFS to the NetApp FAS3070HA system. The FAS270C storage system supports test and development activities. Benefits: AISO continues to achieve year-over-year growth of 20% and still runs completely on solar energy. Since fully deploying the virtual infrastructure, AISO has seen a 70% decrease in energy usage. NetApp Snapshot technology enables data protection with minimal consumption of storage. Online backup functionality has significantly reduced storage requirements for high-cost tape systems with their attendant power, cooling, and space requirements. Redundancy and continuous service availability are key benefits of the new infrastructure. Since deploying the virtual environment, AISO has experienced no storage-related downtime. NetApp Professional Services provided invaluable assistance in the design of the storage solution for the AISO virtual environments. The NetApp team recently worked with AISO to take advantage of NFS to achieve both performance and capacity utilization efficiencies while keeping storage administration simple in its VMware environment. 10 10 10 10

Different Desktops for Different Workers
Task Workers Knowledge Workers Mobile Power Users The objectives of this slide are to introduce Various types of desktop users in a typically organization Which desktop type is most appropriate for which desktop user Pros and cons of each desktop type The key takeaway is that customers will need to be prepared to deploy virtual desktops for all types of users since it’s not a one-size-fits-all. There are four types of desktop users Task workers – perform repetitive tasks using a limited set of tools (e.g. call center operators, transaction processors, customer service reps) Knowledge workers – work primarily with information or develop/use knowledge using an extensive set of tools (e.g. marketing, finance, analysts, consultants, project managers) Power users – Knowledge workers who need unlimited set of tools and flexibility to download/install additional tools and/or powerful computing resources (e.g. software developers, traders, IT administrators) Mobile users – Could be either knowledge workers, power users who travel extensively (e.g. sales) In a VDI infrastructure, there are primarily two types of desktops (although different vendors have different names) Non-assigned desktops can be used by multiple users (although only 1 user at a time). They are not “owned” by a particular user. All desktops are identical images of one another. User modifications are not retained. A user can “grab” any one of the desktops available and log on. When he logs off, the desktop goes back to the pool of available desktops and ready to be used by another user. Non-Assigned desktops are non-customizable are appropriate for task workers and some knowledge workers. Patching for non-assigned desktops is very easy since they are identical. Simply blow away existing virtual desktops and re-create from a new patched golden desktop. Assigned desktops have individual “owners”. Each desktop is slightly different than another desktop, even though there might be similarities in the OS or applications used. A user logs onto his own virtual desktop, when he logs off, his changes are retained. No one else can use his virtual desktop. Assigned Desktops are customizable and are appropriate for some knowledge workers, mobile and power users. Patching for assigned desktops is requires more management. The best way to date is to use traditional patch management tool to patch each individual virtual desktop. There’s overlap with some knowledge workers – they can be provided with either an assigned or non-assigned desktop. The key driver is how restrictive IT wants to be with desktop control policy (in other words, as an IT department, how stringent do you want to be with some of your knowledge workers in terms of how much flexibility they have to customize their desktops. Non-Assigned Desktops Assigned Desktops Ease of management (e.g. patch) Lower storage requirement Limited user flexibility More freedom for users More storage requirement Patch management more difficult

VMware View Desktop Delivery Models
Individual Desktops Manual Desktop Pool Automated Desktop Pool . View Manager . View Manager . View Manager VMware Full Clones or Linked Clones Dynamically created via VMW Full Clones; or Linked Clones Pre-created and populated in vCenter Imported into VMware View Manager The objective of this slide is to explain Vmware’s nomenclature for the various desktop types. Vmware has a confusing nomenclature so be prepared to spend more time on this slide. At the high level, there are three desktop deployments: individual, manual pool, and automated pool. Each desktop deployment may have multiple desktop types. Individual Desktops are Assigned Desktops. The twist here is that Vmware has made it accessible to 1 or multiple users (not at the same time though). Essentially multiple users are permanently “assigned” to a particular desktop and changes made by any of the users are retained and available to any other user. The use case is pretty limited. For example, suppose you have two developers, one in the US and another in India, that are working on a product. You can assign an Individual Desktop to both of them so that they can access the same desktop (but at different times) Manual Desktop Pool is a pool of pre-created virtual desktops. They have no owner when they are first created. Assignment happens at first log-in (in other words, as soon as a user grabs a free desktop for the first time, the desktop is “imprinted” on the user and will be his desktop going forward). There are two Desktop Types possible in the manual pool (although you cannot deploy both types in the same pool). Persistent Desktops are essentially Assigned Desktops. Non-Persistent Desktops are Non-Assigned Desktops. At the high level, individual Desktops and Manual Desktop Pool share the two commonalities – desktops are pre-created in vCenter and imported into View Manager Automated Desktop Pool is similar to Manual Desktop Pool in the sense that can both accommodate Persistent and Non-Persistent Desktops. The difference is that Automated Desktop Pool contain desktops that can be dynamically created. You can set it up so that it automatically creates new desktops and put them in the pool when the pool of available desktops drops below a certain threshold. Provisioning new desktops in an Automated Desktop Pool can be done via either Vmware full clones or Linked Clones. Linked Clones has an additional license fee. Linked Clones is a image management technology from Vmware – it enables virtual desktops to “share” common OS and applications and therefore is very storage efficient. While it is a good technology, it has limited use since it can only be for Non-Assigned Desktops. For more details on Linked Clones vs. FlexClones, see View Deployment training VOD on SalesEdge or PartnerCenter. Pre-assigned to 1 or more users Only 1 active user at a time Customizable Assigned at log-in Persistent Desktops – 1:1 (VM: User), customizable Non-Persistent Desktops: 1:n (VM: Users), (1 active user at a time), non-customizable

Skip this if the customer has already decided to go with VMware Citrix XenDesktop is a hypervisor agnostic. Citrix XenDesktop has their own nomenclature. Assigned Desktops correspond to what we defined as Assigned Desktops earlier. Pooled Desktops are essentially Non-Assigned Desktops. Citrix has different delivery technologies for the various desktops types: Pooled Desktops are delivered via the Citrix Provisioning Server and Desktop Delivery Controller Assigned Desktops do not utilize Citrix Provisioning Server, but does utilize Desktop Delivery Controller Citrix Provisioning Server is a streaming technology that can be used to provide multiple virtual desktops from a single copy of OS in the storage backend. It provides the same image management capabilities as Vmware’s Linked Clones, even though they use different technologies. Similar to Linked Clones, the limitation is it cannot be used for Assigned Desktops. Desktop Delivery Controller is a connection broker. Physical Servers Storage Pool Datacenter 14 14 14

Key Decisions for VDI Storage Planning
Plan for both desktop OS image and user data; separate OS image typically 20 GB, user data can be 2-3x OS image size OS in VM, user data in file share; patch OS images only Separate management policy to OS and user data, e.g. backup user data but not OS Differentiate protocol by data type NFS, iSCSI, or FC for desktop OS CIFS for user data Empower desktop administrators to perform role-based storage related tasks Minimize number of management tools Size storage system to prevent performance bottlenecks Most desktop operation groups do not have the necessary storage knowledge.

Points: Data ONTAP is the foundation of all the virtualization functions and integration, and runs on all the FAS products as well as extending to legacy arrays through the V-Series platform. All of the FAS family leverage the same architecture and can run the same software and management tools, with by far the broadest range of products that can make this claim, again a true differentiator that is very powerful in the virtualized environment. The storage pool can accommodate mission-critical applications along with infrastructure applications, a secondary tier, and also include archiving, all in the same collective pool.

Lower Power, Cooling & Space
Typical: 40% Utilization NetApp: 70+% Utilization Buy 50% Less Storage* Save 50% in Power, Cooling, & Space* waste App 3 8 spindles waste Shared capacity App 2 6 spindles App 3 12 spindles Goal of this slide: Substantiate financial benefits of consolidation with higher utilization. Points: Typical DAS environments are inflexible silos with storage dedicated to each server/application. This is extremely inefficient in that each silo is typically over-provisioned, resulting in wasted capacity and low overall utilization (40% is an industry average). Additionally, if any particular system requires more storage, it is unable to utilize any of the storage from the other systems. Additional storage must be physically provisioned, often resulting in downtime. Consolidation to centralized storage affords sharing of excess capacity across all applications. Combined with thin provisioning (FlexVol), customers can realize utilization of 65% (or even more) with NetApp solutions. All of this allows significantly less storage to be purchased for the same purposes, saving money up front as well as down the road. Less storage means fewer spindles, fewer arrays, less floor space, less power, and less cooling! While this slide depicts thin provisioning, the overall 50% numbers are derived from the Wyman update, which found that a combination of thin provisioning, clones, and the multiprotocol capabilities that NetApp offers all contributed to huge differences compared to HP and EMC. waste 6 spindles App 1 App 2 App 1 Standard Volume Manager NetApp Thin Provisioning Source: Oliver Wyman Study: “Making Green IT a Reality.” November 2007. *Thin Provisioning, clones, & multiprotocol all contribute to savings.

What About Storage Protocol?
To NetApp, protocols simply do not matter NetApp value holds true for all protocols RAID-DP NetApp Dedupe SnapManager for VMware Infrastructure Common deployment trends Small installations tend to use iSCSI Large installations prefer FCP or NFS FCP is most commonly deployed protocol NFS allows direct NetApp data management in VMware® by providing object based storage Majority of VDI customers use NFS
46
Why are so many NetApp customers using NFS for VDI?
More VMs per datastore - >125 VMs for NFS vs. <20 VMs for blocks Fewer objects to manage: 40 objects vs. 250 objects for a 5,000-seat VDI deployment More VMs per datastore enables FlexClone to clone more VMs at a time More VMs per datastore increases overall deduplication savings (dedupe works at volume level) NFS is thin-provisioned by default Dynamic datastore resizing allows easy grow or shrink of the storage as needed Without having to migrate VMs from the datastore Eliminates the need to add extents Savings or increases in storage can be reflected immediately in ESX hosts by refreshing datastores Less overall management complexity Removes need for FC switches, HBAs, zones across ESX servers Clone and restore individual VMs

Cost-Effective Data Reliability
The Problem Double-disk failure is a mathematical certainty RAID 5 (single parity disk) Insufficient protection RAID 10 (mirrored copy) Double the cost NetApp RAID-DP™ Solution Protects against double- disk failure High performance and fast rebuild Same protection and performance as RAID 10 at half the cost Goal of this slide: Solidify RAID-DP as the foundation of data protection. Points: This compares RAID-DP with RAID 5 and RAID 10. While RAID 5 used to be considered adequate, there is only protection for single disk failures. With the sheer number of drives in use today, combined with drive manufacturer issues around similar lifespan on drives manufactured together, it is now a mathematical certainty that data centers must be prepared for double disk failure scenarios. This rules out RAID 5. Many competitors respond with RAID 10, which overcomes some double drive issues (unless on the same side of the mirror) and performs much higher than RAID 5. But these improvements come at a very high price, due to the need to double the raw capacity and thus double the price. NetApp offers RAID-DP, and also backs it up by recommending RAID-DP in best practice. RAID-DP protects against double disk failure, and has the high performance of RAID-10 and the low price of RAID 5. There is no tradeoff with RAID-DP! Typical competitors are labeled on the bottom of the page for comparison purposes. RAID 5 RAID 6 RAID 10 RAID-DP Cost Low High Performance Resiliency Med 47 47 47

Instantaneous Backup, Zero Server Impact
The Problem High server utilization No spare cycles for backups Tape is slow, complex, & expensive DR can be difficult to manage NetApp Snapshot™ Solution Servers run apps, not background processes Instantaneous backup and recovery Low storage overhead Application consistent VM1 VM2 VM1 VM2 CPU Utilization Goal of this slide: Solve the backup and recovery problem identified in the storage challenges. Points: The problem was identified before, where consolidation with virtualization compounds the backup problem so that all the data volumes to be backed up are now resident on a single server (for whatever ratio is implemented, such as 10:1). The server utilization is being unnecessarily taxed to run backups, and may or may not be able to complete within the backup window (most likely not). This also leaves less CPU for the applications, which is really one of the main points for virtualization. So getting background tasks off servers provides more resources for more consolidation focused on application efficiency. Tape is a tedious manual process, where the associated tapes are continually growing (adding to cost and complexity). Recovery is error prone and extremely slow. Tape-based DR is even more complex. Enter NetApp Snapshot with SnapRestore. NetApp has unique value in this area, with industry-leading capabilities that fit exactly in the VMware environment. The backups are run on NetApp storage, and many copies can be made at any time increment in a matter of seconds. These copies are not full copies of data, they are only tracking changes and are very efficient in terms of overall storage capacity. Restores can be done instantaneously from any of the copies. Furthermore, the backups are application aware in that they have been coordinated with the application in a known state and cover the application binaries, the logs, and the application data, which in turn enable the restores to be that much faster as well as return to a known state.

Useable Snapshots for Rapid Recovery
Market-leading performance SPC-1 Performance (IOPS) NetApp 3% difference Snapshots 4/hr First RAID-6 EMC 64% impact Snapshots 1/hr Best practice mirroring Baseline With Snapshots 30,986 24% higher 233% higher 29,958 NetApp FAS3040 EMC CX3-40 NetApp FAS3040 EMC CX3-40 24,997 Goal of this slide: Show actual performance impact on competitive boxes with snapshots enabled. Press release is HERE: Some competitors have said NetApp multiprotocol machines have a performance impact. To prove one way or the other we conducted this validated industry standard benchmark and the results are online on our website. With pure baseline SAN usage with a TPC-like workload, NetApp’s FAS 3040 outperformed a “like” machine from EMC by 24%. ( The EMC machine was set up based on their best practices.) Next, when we turned on snapshots, a practice that is common and needed in the real world, note the dramatic differences in performance. Note that first of all, all snapshots have been done at the storage level, offloading lots of cycles from the host servers, the first win for the customer. Now note the impact of taking the snapshots…the performance impact was dramatically different. Following each company’s best practices, NetApp, with snapshots turned on…taking 4/hour, deleting the oldest, providing 3 recovery points at all times outperformed the similar EMC machine by an incredible 233%...and that was with the EMC box taking a single snapshot per hour providing a less current restore point for applications. Also note that according to each’s best practice to assure data availability, we used RAID-DP or RAID-6, and used mirroring which is what EMC recommends. We won’t even get into the disc space savings of RAID-DP vs. mirroring, as we’ve discussed that previously. The numbers speak for themselves, NetApp outperforms similar machines from its competitors, and offers better snapshot management while providing more cost effective storage 8,997

Business Continuance NetApp SnapManager backups can be moved to tape
from array To tape Goal of this slide: Highlight the options with tape Points: 1. we can backup to tape – minimal changes 2. Backup to tape make not make sense because of dedupe. It’s a lot of work to un-duplicate, copy, and compress with tape. Opens D2D discussions…. NetApp SnapManager backups can be moved to tape No impact to server Maintains CPU & memory efficiency 50

SnapManager for Virtual Infrastructure
Primary Site Policy based management of Snapshots Restores Replication Storage Admin sets and controls policy Virtual Server Admin delegated to run data management for virtual infrastructure SMVI coordinated with Virtual Center VM-aware snapshot VM locality VM1 VM2 VM3 VM4 Virtual Server Admin Virtual Center SMVI API Storage Admin Goal of this slide: Provide an architectural overview of SnapManager for VI Points: SMVI co-exist with Virtual Center and uses API to communicate with Virtual Center to provide requests to the ESX servers for their respective Virtual Machines. Virtual Center communicates with the ESX servers for all management functions, and uses resident agents in the ESX servers. SnapManager for Virtual Infrastructure uses ONTAP API to scheduleSnapshots and SnapRestores functions in the NetApp platforms, as well as invoking SnapMirror for replication of these Snapshots which can be directed at a DR site. Snapshots always happen at the Datastore levels, but restores can be done at the individual Virtual Machine level. POLICIES VM1 VMDK VM2 VMDK VM3 VMDK VM4 VMDK Storage Pool 51 51 51 51 51

VMware View (Formerly VDI)
The picture shows the different components of VMware VDI Solution, known as “VMware View”. It delivers personalized desktops to any user with the benefits of centralized management. It was created using different technologies available in different vmware products. A good example of that is the “vmware view composer” which leverages “linked clone” technology available in VMware Lab Manager. Another component is the “VMware View Manager”, or previously known as “VDM” which centralizes the management of VDI images, user sessions, connection brokering etc. It provides centralized access to VDI images using different kinds of end user PCs/thin clients.
