1. VMware Horizon Suite, Innovations for Storage Scalability, Performance and Data Protection Chris Gebhardt, NetApp Christopher Wells, NetApp EUC5400 #EUC5400
2. Agenda  Design Decisions Dictate User Experience & Scalability – Cloning Choices – Hypervisor Snapshots – View Storage Accelerator  Assessment & Sizing for Horizon View  Backup for Horizon Workspace 2 NetApp Confidential - Internal Use Only
3. You know what “Grinds My Gears”?  Load generation tools represent reality?  Vendors talking only about IOPS  1,000,000 IOP Marketing #’s  Vendors talking only about the desktop  Notion that desktop is easy  Assessments are optional 3 NetApp Confidential - Internal Use Only

5. Decisions, Decisions 5 Connection Broker Horizon View ™ Pool Type Automated Pool Manual Pool User Assignment Dedicated Dedicated Floating Cloning Method Linked Clones Existing vCenter™ VMs VSC Clones Full Clones Linked Clones User and Temp Data Disposable File Redirection Persistent Disk (User Data Disk) Disposable File Redirection Native or VCAI Linked Clones Native or VCAI Linked Clones NetApp Confidential - Internal Use Only
6. Cloning Can Cost You!  What the costs are  How to avoid paying them 6 NetApp Confidential - Internal Use Only
7. Hypervisor Clones (Snapshots) 7 Hypervisor OS TEMP - Δ APP NetApp Confidential - Internal Use Only
8. OS APP TEMP - Δ Hypervisor Clones (Snapshots) 8 Hypervisor OS Disk (Snapshot) Replica Disk (C:\ drive) NetApp Confidential - Internal Use Only
9. Hypervisor Clones (Snapshots) 9 One Write from VM One Data Write 1 Guest Write = 3 Storage I/Os One Metadata Read One Metadata Write 1 Guest Read = 3 Storage I/Os Hypervisor Replica Disk (C:\ drive) OS APP OS Disk (Snapshot) TEMP - Δ NetApp Confidential - Internal Use Only
10. Hypervisor Clones (Snapshots) 10 Any Storage (Including DAS) Hypervisor Replica Disk (C:\ drive) OS APP OS Disk (Snapshot) TEMP - Δ 1 Guest Write = 3 Storage I/Os 1 Guest Read = 3 Storage I/Os NetApp Confidential - Internal Use Only
11. The Breakdown 11 10 IOPS 20% Reads, 80% Writes 2 I/O Reads 8 I/O Writes 1 Metadata Read 1 Data Read 1 Metadata Read 1 Metadata Write 1 Data Write 4 Reads 8 Reads 16 Writes 10 guest IOPS = 28 IOPS to storage X = X = NetApp Confidential - Internal Use Only
12. The impact of snapshots on ANY storage VM IO Storage IO Inefficiency Inefficiency New Writes Overwrite 12 NetApp Confidential - Internal Use Only
13. Where Does the I/O Go?  Created workload with linked clones  Collected I/O statistics – User persona/profile = 52% – User data = 45% – C Drive = 3% 13 NetApp Confidential - Internal Use Only
14. Horizon View Cloning Recommendations 14 Persistent Non-Persistent User Assignment Dedicated Floating Deployment Technology Full Clone with VAAI Native Linked Clone w/ SESPARSE Storage Efficiency Block Level Deduplication Replica/Refresh Maintenance Standard Patching Practices (Stagger) Recompose Caveats Template must reside in destination datastore Additional IO for Metadata NetApp Confidential - Internal Use Only
15. Horizon View Cloning Futures! 15 Persistent Non-Persistent User Assignment Dedicated Floating Deployment Technology Full Clone with VAAI VCAI Storage Efficiency Block Level Deduplication Replica/Refresh Maintenance Standard Patching Practices (Stagger) Recompose Caveats Template must reside in destination datastore Additional IO for Metadata NetApp Confidential - Internal Use Only
16. View Storage Accelerator  Host-based memory cache  All types of desktops except VCAI  Transparent to user OS and applications  Helps to reduce storage costs for legacy storage  Significant time to generate and regenerate digests 16 NetApp Confidential - Internal Use Only
17. NetApp Virtual Storage Tier  VST helps alleviate boot and login storms  Allows sizing for writes and steady state  Flash Cache™ is available only on selected platforms  Flash Pool™ – Can be used for reads on platforms that don’t support Flash Cache – May help to absorb writes from spinning media (Depending on workload in VM) – Cache is persistent across reboots 17 NetApp Confidential - Internal Use Only
18. NetApp Offers A Complete Flash-Accelerated Storage Portfolio 18 All Flash Arrays Flash only Server Cache Hybrid Storage Flash + HDD Traditional Array HDD only Flash Accel and server cache partners Flash Cache Flash Pool SSD Cache FAS/V-Series E-Series EF-Series FlashRay Complete Portfolio of Offerings for Any Workload NetApp Confidential - Internal Use Only

20. The NetApp Solutions Approach 20 There is more to VDI then just the operating system! NetApp Confidential - Internal Use Only
21. Design a Solution! 21 Corporate Apps Volume User Data Volume Virtual Machine Volume Corporate-Published Applications Microsoft® Windows® 7 Operating System Swap and Temporary Files Corporate-Installed Applications User Profile End-User Data (Home Directory Data) User-Installed Applications NetApp Confidential - Internal Use Only
22. Clustered Data ONTAP Simplifies Horizon Suite 22 500 1,000 2,500 5,000 5,000 10,000 25,000 50,000 Corporate-Published Applications Microsoft ® Windows ® 7 Operating System SWAP & Temporary Files Corporate-Installed Applications User Profile End-User Data (Home Directory Data) User-Installed Applications NetApp Confidential - Internal Use Only
23. Because the reality is… Clustered Data ONTAP Profile User Data Desktop Apps Exchange Infrastructure SVM SVM SVM SVM SVM SVM Server Hypervisor Storage Hypervisor 23 NetApp Confidential - Internal Use Only
24. And storage needs to be non-disruptive 24 Clustered Data ONTAP SVM SVM SVM SVM SVM Migration, Maintenance These stay online! Profile User Data Desktop Apps Infrastructure NetApp Confidential - Internal Use Only
