 Technical Overview
 Virtual Application Delivery System
  Chosen from a One Year Pilot Study
 VMware’s Virtual Desktop Infrastructure,
  View




What is it?
 Convenient access to resources anytime-anywhere is
  essential to successfully serving the needs of the UVa
  community.

 Universities must recognize emerging trends and align
  services accordingly.

 Facilitate UVa students’ access to specialized software for
  academic purposes, freeing them from reliance on public
  machine's in a single physical location.

 Virtualized delivery allows students and faculty access in
  any collaboration space, whether physical or virtual.

 More efficient operations has enabled us to increase our
  capabilities with decreased staff and decreased budget.

 Simplifies software package creation, delivery and
  maintenance, requiring less staff time.

Why?
 VMware’s Hypervisor Infrastructure called
  vSphere ESXi
 Hardware Solution for ESXi
 Shared Storage for ESXi
 Properly Configured Network Backend
 Active Directory
 Dynamic DNS and DHCP
 Security




Dependencies
 VMware’s Powerful Virtualization Technology; ESXi
  4.1
 Supports a Variety of Guest Operating Systems
  ◦ Windows XP, Vista, 7 (32 and 64 Bit)
  ◦ Windows 2003, 2008, and 2008r2 Server (32 and 64 Bit)
  ◦ Linux: Red Hat (2-6), Ubuntu, Suse, etc. (32 and 64 Bit)
 High Availability
     Automatic Detection of OS and Host Failures
     Health Monitoring of Cluster; i.e. Misconfiguration detection
     Automatically Monitors Available Resources via Distributed
      Resource Scheduler
     Scalability
 vMotion and Storage vMotion
     AKA Live Migration
     Load Balancing and Failover
     Maintenance
 vCenter Server for Client Management
 Shared Storage
  ◦ NFS via Netapp 3170

The Hypervisor
   Six Dell R710 Servers
   Hexcore X5650 2.67GHz Processors
   96 GB RAM
   Two 146 GB 15K SAS Drives for ESXi OS




ESX Host Hardware
 Netapp 3170
 NFS
 De-duplication
 PAM Cards for Read/Write Caching
 15K Fiber Disk Shelves
 Many Spindles; Small Disk for Better
  Performance
 Offers Redundancy and Proves Reliability
 18 TB of Storage Utilizing Eight Datastores; Four
  per Head



Shared Storage for ESXi
 Re-architected Existing Backend to Best Practice
  Standard
 Arista 10G Switch Pairs
 Use 802.3ad Dynamic Link Aggregation and vLAN
  Trunking for Load Balancing and Redundancy
  ◦ vMotion, Storage, and Management Networks




Network Backend
 New Child Domain of Eservices, View
 Uses DDNS vs. Bind
 DHCP




Active Directory
 Hardware Firewalls and VPN to Protect
  Infrastructure
 Active Directory for User Authentication
 Group Policy




Security
   Virtual Desktop Infrastructure
     ◦ Broker
           Two brokers behind an F5 for High Availability and Load Balancing
           Integrates with vSphere
           Access via Browser or Client
           Organize Desktops via Pools
           Load Balancing; Automatically Add VM’s on Demand
           Automatically Monitors and Assigns VM’s
           Management
     ◦ Storage Optimization
         Snapshot of Parent VM Taken and Deployed as Replica
         Linked Clones Using Composer
         One Replica per Datastore for Load Balancing and Redundancy
     ◦ VM Management
         Always Maintain a Fresh Image on VM
            ◦   VM Set to Refresh to Original State Upon Logoff
         Updates
            ◦   Parent VM Snapshots
            ◦   Snapshot Assigned to Pool for Deployment
     ◦ Resources
         Virtual Printing
         USB Redirection
         Multimedia Redirection
     ◦ Application Virtualization via ThinApp
