Introduction

Desktop Virtualization

In this session we will focus on how a virtual desktop environment can save money, dramatically ease desktop management, improve security, and offer tremendous flexibility. Cisco is uniquely qualified to solve this problem since servers, storage, network, and security are keys to successful deployments. Additionally key hardware and software innovations for desktop virtualization will be described including storage acceleration and UCS GPU solutions.

Caveats:• This assumes the data stored on the node can be reduced at that rate.• Do not quote these numbers as up-front guarantees for ANY customer unless we’ve run tests on

their data, or it’s been blessed by director/executive support.

Recommended best practice is to use only 70% of usable capacity

Agenda





• Conclusion

48


Desktop Virtualization Considerations• Business

– Identify worker types (i.e. Task, Knowledge, Power, etc.)– Pursue when it makes business sense– Address security and compliance requirements– Consider the workspace including desktop, voice, video, and broadcasts– Consider the employee onboarding and off-boarding workflow

• Design– Fault domains– Disaster recovery– Shared storage scalability– Application concurrency– Per application requirements (One bad app ruins a bushel!)– Rich media or graphic intensive applications have many caveats– Stateless desktop is the goal

49


Desktop Virtualization Approach• Centralized when you can

– Communications – Email– Productivity – Office, Wiki– Information Management – File, Sharepoint, iDisk, etc.– Business applications – Client/Server– Business intranet web

• Local when you must– Communications

• IP Telephony (interactive softphone)• Video on demand (native encoding with local caching and prepositioning)• Video streaming (broadcast)

– Rich media web• Experience• Branch split VPN with local web access

– Print50


Desktop Virtualization Deployment

• Phase 1: Key IT staff

• Phase 2: Most IT staff at most sites

• Phase 2: Extended power user group including several sites of multiple types.

• Phase 3: Extended power user group including most sites.

• Phase 4: Partial rollout based on sites or groups of sites.

• Phase 5: Additional partial rollout based on sites or groups of sites.

• …

• Phase x: Full rollout (can be split into sub-phases)


52

Desktop Virtualization Device Considerations

• Repurposes desktop (continued use of legacy devices)

• Zero clients (fixed function devices)

• Thin clients (extendable devices)

• Tablet devices (phones and tablets)

• Traditional compute (laptop and desktop)


Data Center Considerations• Requirements by desktop type

– Hosted Virtual Desktop (HVD) – One user per VM

– Hosted Shared Desktop (HSD) – Many users per VM

– Published Desktop – Many instances of one application per VM

– Web Desktop – Many users per web server

• Compute– Scale– Cost– Performance– Power/Cooling– Space– Cabling

• Storage– Scale capacity

• Linked clones• Flex Clones

– Scale IOPS

• Network– Security– Monitoring– IP address management– Bandwidth

• Typically a LOT less LAN traffic• Typically a LOT less WAN traffic• Typically growth in WLAN traffic

53


54

Compute CPU Considerations for Virtual Machine

• CPU class – CPU class is affected by number of cores, CPU clock speed, amount of cache memory

and CPU virtualization technology

• CPU core count – CPU core count affects virtual machine scalability and performance

• CPU over commitment – CPU over commitment occurs when the number of virtual CPUs assigned to the virtual

machines exceeds the number of physical CPUs available to the host

• Virtual machine role priority – Virtual machine role priority determines how CPU resources are distributed across

virtual machines


55

Compute CPU Capacity Planning

• Percent Processor Time ~10% on 2x2 GHz core

• Requires 400 MHz per desktop (0.10 * 2 * 2 GHz)

• 100 desktops require 40 GHz processing (100 * 400 MHz)

• Add 25% overhead for virtualization, display protocol, and buffer for spike for a total of 50 GHz

• 100 desktops achieved with 50 Ghz via 21 cores at >=2.4 GHz per core

• Planning– Windows XP 150-250 MHz– Windows 7 400-600 MHz


56

Compute Memory Capacity Planning

• Vmware ESX Transparent Page Sharing to share master copy of memory pages among virtual machines– Windows XP - 4 KB page sharing– Windows 7 - 1 MB page sharing

• Planning Without Memory Oversubscription– Windows XP - 512-1024 MB– Windows 7-32 bit - 1-1.5 GB– Windows 7-64 bit - 2-3 GB


Storage Terms

• File Access– User - Common Internet File System (CIFS) / Server

Message Block (SMB)– Virtual machine - Network File System (NFS)

• Block Transport– Small Computer System Interface (SCSI)– Internet SCSI (iSCSI)– Fibre Channel (FC)– FC over Ethernet (FCoE)– SCSI over FC over IP (FCIP)

• Data Deduplication– NetApp File Level Flex Clone– VMware Linked Clone– Atlantis Computing iLio– Citrix Intellicache– VMware Storage Accelerator– Transport WAN acceleration

• Data types– Virtual machine– User data– Profile or layers– Virtual applications

• Storage– Storage Area Network (SAN)– Network Attached Storage (NAS)– Direct Attached Storage (DAS)

• File System– NT File System (NTFS)– File Allocation Table (FAT)– Extended File System (ext3)– Virtual Machine File System (VMFS)– Raw Device Mapping (RDM)

57


Desktop Virtualization Local Storage Options

• Options: – Storage on Servers – SSD, HDD, RAM Cache

• Image Cache on Server (up to 45% reduction in required IOPS)– Citrix IntelliCache on XenServer 5.6 SP2 (SSD on server)– VMware Storage Accelerator for View 5.1 (RAM Cache on server)

• Write Cache on Server (up to 40% reduction in required IOPS)– Write Cache on target server, or PVS Server (SSD on Server)– PVS server with Read RAM, Copy of vDisk (RAM and SSD on Server)


Storage CapacityVMware Linked Clones or Microsoft Differencing Disks

• Full Images– Capacity equals base OS/App/Data size plus

suspend/resume (RAM size), page files, etc.– Copy of a VM (at a given point) with a separate

identity– Can be powered on, suspended, snapshot,

reconfigured, etc. independent of the VM it was cloned from

– Full clone wastes storage and is slow to clone– Replica is a full clone created from the gold master– Master VM can be updated or replaced without

affecting the replica

• Linked Clones or Differencing Disks– Storage reduced 90% to 50% over full clones– Redirect folders to a separate optional user disk (i.e. D:)– Rapid provisioning desktops vs. full cloning– Copy of the original virtual machine that shares the virtual

disks with the original virtual machine– Operations

• Refresh – Clean desktop, Pristine image• Recompose – Migrate existing desktops from one version to the

other• Re-Balance – Re-locate desktops to enable efficient usage of

the storage available (add more storage or retire existing array)

59


Storage NFS Linked Clone Storage Capacity Consumption• Replica is a full clone

• Linked clone consumes <10%

• Linked clone bloats over time

• Expect about a 50% savings depending on desktop type/use

Storage Performance Planning

• Realities– I/O performance matters– Read / Write ratios matters– Workload may exceed 80-90%

WRITEs– Problems not in small environments

(<300 users)

• For example– HDD offers up to ~200 IOs per drive– At 40 IOPS per user, 5,000 users need

~200,000 I/Os or 1,000 HDD spindles– Each I/O is at least 4096 Bytes

• Planning (single user steady state)– Windows XP 5-10 IOPS average– Windows 7 10-20 IOPS average


UCS Chassis

IO Planning Example Bandwidth Planning• Storage (in and outbound)

– 20 IOPS nominal per desktop at 4K Bytes EA– 671 Kbps EA (assume 1 Mbps)– 1 Gbps for 1000 HVDs in UCS blade chassis– Assume 1 Mbps per HVD

• Network Display (mostly outbound)– Assume 1 Mbps per desktop– 1 Gbps for 1000 HVDs in UCS blade chassis

• Desktop Protocols (mostly inbound)– Estimate 8 Mbps which opens 25MB in 25 seconds

and handles streaming and interactive video– 8 Gbps for 1000 HVDs in UCS blade chassis

• Total– 10 Mbps per HVD for storage, display, and desktop

protocols– 10 Gbps for 1000 HVDs in UCS blade chassis

Storage Design impact of Desktop Virtualization

• Impact 1: Capacity– Linked vs Full Clones vs Provisioned– Personalized desktops– User capacity

• Impact 2: IOPS– Boot storms, login storms, AV updates/scans– IntelliCache, VMware’s CBRC, Write Cache

• Impact 3: Protocol/Connectivity– NFS/block (for XS, ESX), CIFS/block (for Hyper-V)

• Impact 4: Storage/DC Services– DR/HA, Application Mobility, backup


Understanding IOPS

• IOPS are the number of disk operations that take place in one second – usually refers to the combination of READ and WRITE operations

• Factors that affect disk performance:

• Average rotational latency • Average seek time• Response time = average rotational

latency + average seek time• I/O data transfer rate• Data location – sequential or random

Storage IOPS: Dedicated Workstation vs. Hosted Virtual Desktop• Local disk (typically SATA disk @ 5,400 or

7,200 RPM)– Can deliver between 50 and 100 IOPS

• OS, services, and applications loaded into memory at start-up (high READ I/O)– I/O to and from disk is optimized for sequential access

• After system is loaded, most IOPS are WRITE commands– As high as 10/90 (R/W), but typically closer to 70/30

• Typical steady-state IOPS for Win7*:– Light user: 4-5 IOPS

– Medium user: 9-12 IOPS

– Heavy user: 18-25 IOPS

• Shared storage is typically used

• Enterprise class SAS or FC disk

• Can deliver between 180 and 200 IOPS (15,000 RPM) each disk

• # of disks and RAID level affects overall performance

• Thousands of virtual desktops accessing shared storage simultaneously

• “I/O blender” effect – all I/O is random

• Windows optimizations and services not helpful (harmful in some cases)

• Slow storage performance affects all users

• Users starting systems in the morning or logging off in the afternoon

• Anti-virus or backup jobs

Use capacity planning tools to determine IOPS load for your environment

Network Security Considerations• Recommendations

– Zone by user/group, application, desktop, data– Apply campus network security features

• Patching– Persistent desktop versus non-persistent desktop

• Virus scanning– Virtual machine virus scanning– VMSafe service in vSphere– NAS (file server) based virus scanning– Network or proxy based virus scanning (Scansafe/Ironport)

• Virtual desktop access– Direct internally or proxied externally
