Virtual Desktop Infrastructure Overview

- 2. Definitions • Server Based Computing (SBC) − AKA Terminal Server Environment • Citrix XenApp (formerly Presentation Server or MetaFrame) • Microsoft Terminal Server • Virtual Desktop Infrastructure (VDI) − Virtual Machines running a desktop OS • VMware View • Citrix XenDesktop • Microsoft Hyper-V • Consolidated Client Infrastructure − Bladed PCs that reside in the Data Center • HP CCI • Blade-based Professional Workstations
- 3. The need for Remote PCs Heterogeneity High Management Costs Admin Inefficiencies > 70% of TCO ($6,800* / user/ year) Too tactically focused ) *Gartner -IDC -IDC Security Threats Low Resource Utilization Need for preventive/ proactive measures Data Theft Virus / Malware The desktop is the least utilized resource on the Phishing Hacking network!
- 4. Remote PC Benefits Close to IT Operations − Desktops are centralized in the Data Center − For VDI: Can reduce the amount of images to manage − Management tools access the “desktops” over local networks for patching/maintenance Increases flexibility − Enables pooling and sharing of desktop infrastructure − Improves disaster recovery plans − Roaming profiles allow users to access from any device − Can pair technologies such as VDI and SBC in a single solution Security − Remote users only ‘view’ data − For VDI: All data resides on RAID storage behind the firewall

- 6. Distributed vs. Remote PCs What is the difference? Apps Apps Win OS Win OS Virtual Virtual Applications Machine Machine Application Windows OS Hypervisor Windows OS PC Blade Server Server Applications HP Session Citrix or Allocation Mgr Connection Broker Terminal Services Windows OS RDP/RGS RDP RDP/ICA Personal Computer Thin Client Thin Client Thin Clients Remote PC Distributed PC HP CCI HP VDI Terminal Server/Citrix • Single user per Desktop PC Multiple users accessing Multiple users accessing Single user per Blade PC virtual PC’s per server applications per server Current Paradigm Security and Data Backup Performance Lower Total Costs Standard Remote Access and Disaster Recovery Most Flexible Improved Environmentals
- 7. “Static” or “Dynamic” Implementation Two Basic “Static” Model “Dynamic” Model Implementation’s Static 1:1 Every user assigned a VM connects by it’s IP Address or Name Connection Broker Dynamic Proliant/Blades Connection broker Running connects user to a Windows VMs VM in a pool and Or CCI HW returns VM to pool when the user disconnects
- 8. Step 1: Access Device for Client Virtualization - Access device can be a thin client, a notebook or a desktop PC - Thin Client benefits - Eliminates end-user “break-fix” - Highly secure - Minimal management/updates (small image) - Reuse desktop/laptop - Users gets Windows XP or Vista -Standard PC applications work -Must still manage large images -Zero Client -No image at device -Only need to update a VM
- 9. Step 2: Broker / Allocation Server - User inputs standard credentials (Name, Password, Smartcard, etc) - Broker determines correct resource for user (Blade PC, Virtual PC, etc) - Examples include: HP Session Allocation Manager, VMware View Manager, Pano Manager
- 10. Step 3: Computing Resource Step 3: Resource Assigned Option #1: VDI - Virtual Windows Vista or XP loaded onto server - Multiple users per server (~8-10 per CPU core) - User is connected via remote protocol (RGS, RDP, ICA, Console Direct) to their “virtualized” client PC - Remote protocol transmits only keystrokes, mouse clicks and screenshots - No corporate / end user data is transmitted to the access device
- 11. Step 3: Computing Resource Step 3: Resource Assigned Option #2: Blade PC or Workstation - Windows Vista or XP loaded onto local hard drive - User data folder-redirected to other storage - Dedicated performance to user while logged in - User is connected via remote protocol (RGS, RDP, ICA) to their “virtualized” client PC - Remote protocol transmits only keystrokes, mouse clicks and screenshots - No corporate / end user data is transmitted to the access device
- 12. Protocol Overview Microsoft Remote − Standard Windows Remote Viewing Protocol Desktop Protocol − Good performance, supports audio output (RDP) − Supported by VMware Citrix Independent − Highly secure, encrypted traffic Computing − Bi-directional audio support Architecture (ICA) − High performance over WAN HP Remote − Superior graphics performance Graphics Software − Per-node Licensing required from Hewlett-Packard (RGS) − Supported by VMware − Superior graphics and USB performance Pano Console Direct − Optimized video with synchronized audio − VMware support only (requires Pano Zero Client device) − To be incorporated into VMware PC over IP (PCoIP) − High Performance; more forgiving for high latency
- 13. VDI Benefits – Economies of scale VM management − One base image can be used for many different VMs • driver management is greatly simplified because all VMs use the same virtual hw − Templates can be created for rapid deployment of new VMs Utilize existing virtual infrastructure − Virtualized server and desktop spaces can leverage the same hardware, architecture, and infrastructure. − Automatic load-balancing and high availability including instant VM migration from host-to-host features. Desktop infrastructure − Underutilized desktop assets − 5w vs 20w vs 120w (Zero Client vs Thin Client vs PC)
- 14. Sample Virtual Desktop Infrastructure on HP BladeSystem c-Class VMware: up to 20 XP users/core Citrix Xen: No CPU limits • Solution Sample for VDI: − 8 BL490c’s and 8 SB40’s − 4GB RAM per core − 8 NICs per Host − 80 VMs per blade − 640 users per 10U • Pair a BL490c with an SB40 • Solution will be 30% to 35% less costly • Each SB40 offers 1.5TB of than using DL380’s with MSA50’s RAID 5 storage • Solution will use ~30% less watts than • Virtualization Layer on Blade equivalent DL380’s & MSA50’s Hard Drives or with an • Less cables & networking costs Integrated Hypervisor • Equivalent response times to DL380 based solution.
- 15. Identifying VDI Candidates No Guessing Allowed − Objective tests are critical − However: work with the user: User Acceptance is KEY! Make them feel that their opinions are important • Many companies are offering incentives to employees • Allowing them to select their own client device • Providing dual-monitors • Other creative examples
- 16. The Basic Methodology for VDI Assess Categorize users and applications, identify use cases, measure usage, determine environment limitations and needs Monitor and adjust Identify target users resource allocations, and use cases, Manage provide software select technologies, Design upgrades and patches, model architecture support end users and capacity needs Virtualize applications, virtualize target desktops, migrate user settings and documents, deploy to desktops and terminals Deploy
- 17. Gather Key Usage Metrics Dissolvable agent measures usage: • Per user, per app • Time in use • CPU • Memory • Disk • Network • Latency • Graphics intensity • Login duration • App load times
- 18. Determine VDI Fitness Rating See how well specific machines, users and applications fit in VDI: • Analyze by group • Workload statistics • System CPU • User CPU • Memory Use Best Fit • Paging • Disk I/O • Network I/O • Advanced metrics Worst Fit • User logons • App loading • Network latency • Graphics intensity • Categorize workloads • Customizable ratings
