Delivery Protocol

VDI Server Hosted Virtual Desktops


• Organizations will virtualize exponentially more PCs than servers

• Storage -Disk I/O – Time congestion and synchronized behaviors require efficient I/O and storage systems (boot & AV Storms). Tiered storage, dedupe, SSD, caching

• Memory – as much as possible

• Networking – major shift/ increase in traffic, need to consider increasing LAN and WAN connection speeds, WAN optimization

VDI Infrastructure Issues/impacts


• Boot Storms 30 -120 minutes • Initial OS and app load from disk • Patching, AV scans, EOD logoff • Profile/measure user resource usage with real

workloads • I/O Blender • Vendors like Lakeside Software, Liquidware Labs,

Flexera … collect data from users’ desktops to assess environment and need

• Tools like esxtop or Perfmon and from storage vendors to measure IOPS

• New SSD appliances help get below $200 per virtual desktop – with performance & capacity

VDI Storage


• Which apps need to be delivered to which end users?

• Which users need app access versus full desktops?

• Which desktop OSs needs to be deployed?

• Will remote (WAN) or mobile users be involved?

• What level of performance is required?

• Will support be needed for offline/disconnected users?

• What type of graphics capability do various users require?

• What level of security is needed?

• How will the overall system and individual VMs be managed?

• How much control will the end user have over the virtual environment?

• How will VMs be backed up? How will VM images be updated?

• What are the requirements for business continuity/disaster recovery?

DV Considerations


• IOPs – Much different than servers

– Major limiting resource

• Storage – Footprint

– User data

• Memory and CPU – Major limiting resource

– Number of blades

Assessment – Capacity

Planning


Hardware

• Servers – More memory – I/O Networking options – Graphics support – Reconfiguration flexibility – Price/performance – VM Density

• Storage – SSD – local or central – Converged compute/storage

• IO Management

– Image optimization – Provisioning – Protocol – SAN Cache vs. Local Storage – Deduplication

Hypervisor &

Client Broker

• Broker can be

different than

hypervisor

• Cost vs. Management

• Scaling and VM

Densities

Hypervisor


Client Broker

• Existing Desktops/Workstations/Laptops – Use current desktops as dumb terminal

– No upfront CapEx investment

• Thin Clients

• Zero Clients

• Tablets

• PDAs and Smart Phones

• Future Devices?

• Access to desktops? Applications? Data?

• Native device apps

User Access Devices


Thin/Zero Client Benefits

• Benefits of TC computing model – Minimal-to-no SW updates at

desktop devices

– Reduced support of users

– Extends lifespan of desktop devices

• For thin/zero client devices – Less vulnerable (smaller attack

surface)

– Green - Reduced power/cooling

– CapEx, OpEx


• VMware: Horizon Suite (View on vSphere, Workspace,

Mirage), RDP, PCoIP, ThinApp, Desktone

• Citrix: XenDesktop on XenServer, (or ESX or Hyper-V),

Desktop Provisioning, ICA, HDX, FlexCast - XenDesktop

includes XenApp, XenClient, Receiver, Cloud Gateway,

CloudStack/CloudPlatform, ShareFile, VDI-in-a-Box

• Microsoft: VDI Suite on Hyper-V, Windows Server Remote

Desktop Services, RDP, Windows 7/8, App-V, MED-V,

RemoteFX, Systems Center 2012 (SCCM, AppController)

Desktop & Application Delivery Hypervisor Integrated Solution


DaaS - Cloud-hosted desktops

• Virtual desktops and apps from the cloud to any device with an Internet connection

• DaaS gaining traction vs other public cloud usage due to benefits of VDI without the complexities

• No SPLA for Win 7 or 8 VDI – most running published Windows Server desktop


• Understand your use cases before selecting solutions – flexibility to meet your use cases – (VDI, hosted apps, client virtualization, app streaming, BYO/mobile)

• Design user experience for your use cases – from zero client to advanced graphics

• Design for IT Efficiency – Storage – image mgmt, thin provisioning, dedupe, storage

optimization for VDI – Consolidation/density ratios in your environment – Bandwidth – LAN, WAN, networking impact – Consider integrated solutions

• Consider integration with app virtualization & app stores • Support for tablets/mobile – integration with BYO policies • Profile mgmt/personalization/ user virtualization • Administrative capabilities – ease, robustness

Client Virtualization Success factors


• Examine ALL your use case requirements

• Consider all access devices – PCs, thin/zero clients, tablets, mobile

• Consider desktop management and BYOD under a unified strategy

• Build cross-functional team (server, desktop, storage, net, security)

• Consider storage , networking & compute as key parts of decision

• Evaluate both user experience and IT infrastructure (storage, network and compute) impacts

• Don’t just treat desktops like servers

• Consider licensing implications – compliance & optimization

• Include both CapEx and OpEx in any ROI/TCO analysis

• Consider but don’t limit to your installed virtual. vendors

• Don’t be afraid of mix and match solutions

• One size does NOT fit all
