Transcript of Redefining the Desktop Stu Baker AUL for Library Technology [email protected].
Overview
• Current environment• Advantages and Challenges• Desktop Virtualization technologies• Use Case Scenarios• NUL Virtual Desktop Strategy
Current In-House Environment
• 800 workstations• Windows and Macintosh• Desktops, Laptops, Netbooks• 40 servers in-house• 7 TB of SAN storage
Time is Money, Money is Time
• Manage apps and OS on every device• Changes, additions are time consuming• Dealing with security and data recovery
is more complex• Hardware replacement cycles
expensive
Advantages of Virtual Desktops
• Flexibility for Users and IT staff• Any device anywhere and anytime• Multiple desktops from a single device• Data recovery, business continuity• Security• Space• Green
The Challenges
• Not a one-size-fits all solution– It may not work for some users
– IT staff need to match the users with the right technical solution
• Performance• Peripherals• Scalability• Cost
Desktop VirtualizationTechnologies
• Hosted shared desktops • Hosted VM Desktops (VDI)• Hosted Blade PC desktops • Physical Desktop on demand apps• Local Streamed desktops• Local VM-based desktops (offline)
Use Case Scenarios
• Virtual Computer Lab• Information Commons• Single use workstations• Specialized Faculty use• Specialized Staff use
The Server (Dell R710)
• 2 Intel Xeon X5680 chips - 3.33GHz
• 6 CPU cores per chip (12 total) w/ Hyper threading a total of 24 logical processors
• 48 GB of RAM.
• 345 GB of storage on Equallogic SAN
• VMware View 4.0.1 andVMware vSphere 4 Update 1
Thick client(Acer Aspire R3610)
• Windows 7 Professional
• 2 CPU's allocated to each VM
• 2 GB of RAM allocated to each VM
• 30 GB of hard drive space per VM allocated dynamically
• VM only stores the delta's from the base image which is a few GB per VM
NU Library Strategy
• Starting small with Info. Commons• Expand to single use workstations• Staff Admin Rights• Mac users• Disaster recovery/business continuity• Single-pane of glass management tools
