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

NetApp Sets the Tone for Radio Television
of Serbia and EuroSong 2008
 Business Challenge
–
Create high-performance, reliable virtual
infrastructure to support real time broadcasting.
 Solution
As the public broadcaster in Serbia,
Radio Television of Serbia (RTS)
broadcasts and produces a variety of
news, drama, and sports
programming through radio,
television, and the Internet. RTS is
the biggest broadcaster in the former
Yugoslavia and the Balkans and is a
member of the European
Broadcasting Union.

NetApp and VMware for VDI
 Benefits
–
–
–
Achieved high performance levels necessary for
content-rich broadcasting scenarios
Gained fast, reliable backup and recovery of vital
audio and video files
Supported press room for over 3,500 journalists
generating text, Web, and audiovisual content in real
time
“Journalists were surprised with the speed of the VDI and curious to know what technology was
at the heart of the infrastructure, as such a reliable, high-performance data delivery service was
new to most of them. We received comments from all over Europe congratulating us on the
most technologically advanced press center and the best service ever delivered at any song
contest. We owe that success to NetApp.”

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

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
© 2008 NetApp. All rights reserved.
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

The Problem

expensive
 DR can be difficult to manage
 Servers run apps, not background
processes
 Instantaneous backup and recovery
 Low storage overhead
 Application consistent
