Title: Virtualization Directions

Virtualization
  • What is virtualization?
  • Virtualization at CITES
  • Future directions
  • Questions?

3
What is virtualization?
  • Run multiple OS instances on a single physical
    server
  • Different types
  • OS level
  • Full virtualization

4
CITES Environment
5
Services and Systems
  • 543 services
  • Critical services
  • Test/dev/prod/warm-spare machine
  • Other systems
  • Some combination of above

6
Physical Systems
  • SPARC
  • 200 Solaris SPARC Systems
  • Some older power inefficient machines
  • x86 Environment
  • 50 Windows
  • 90 RHEL

7
Problems
  • Underutilization
  • Most servers less than 20 CPU
  • Server Sprawl
  • One application/server
  • Deployment time

8
Physical Server Costs
  • Purchase ( Thousands)
  • Power/Cooling
  • Power (180 W) 78/year (0.05/KWh)
  • Cooling cost gt Power cost
  • Data center space ()
  • Hardware support contracts

9
CITES Virtualization
  • Solaris Zones
  • OS-level virtualization
  • VMware
  • Bare metal hypervisor
  • Each OS instance is virtualized

10
Virtual Infrastructure
  • Solaris Zones
  • Deployed in Test/Dev/Production
  • VMware
  • Ongoing project
  • Test/dev VMs and low priority production systems

11
Solaris Zones
  • Isolated user environments share kernel
  • Whole root zones
  • Each zone has its own copy of system files
  • Sparse zones
  • Share system files with the global zone

12
Zones Servers
  • One development server
  • Sun V440 (4 1.04 GHz processors, 8 GB RAM, 144 GB
    disk)
  • 23 zones

13
Zones Servers
  • Two production servers
  • Sun V490 (4 1.05 GHz processors, 16 GB RAM, 146
    GB disk)
  • 18 zones

14
Limitations
  • Some packages must be installed in the global
    zone
  • Would use sparse zones in the future
  • Zone can not be NFS server

15
VMware
  • VMware Virtual Infrastructure 3 (VI3)
  • Four ESX Servers
  • Forty VMs
  • Growing!

17
VMware Servers
  • HP ProLiant DL380
  • Dual Quad-Core (2.0 GHz Intel)
  • 32 GB RAM
  • Sun x6250 Blade
  • Dual quad-core (3.0 GHz Intel)
  • 64 GB RAM

18
VMware Storage
  • SAN
  • Two tiers of storage
  • Reduce costs
  • Tier II (Sun StorageTek)
  • Tier III (NexSan)

19
VMware Network
  • Six physical GigE ports/server
  • VLAN Trunking for VMs
  • Reduce the network ports on servers and switches
  • Increase redundancy

22
VI3 Features
  • VMotion
  • Storage VMotion
  • Distributed Resource Scheduler (DRS)
  • High availability (HA)
  • Remote command-line and perl toolkit

23
CLI and Scripting
  • Remote command-line interface
  • VI perl toolkit

24
VMware Tools
  • Manual installation and configuration
  • Tools are essential
  • Network driver
  • 10-fold performance enhancement
  • Memory Ballooning Driver
  • Swap in hypervisor rather than in VM

25
Limitations
  • Linux support
  • VI client only runs on Windows
  • Timekeeping
  • Tools packaging

26
Physical Server Costs
  • Purchase ( Thousands)
  • Power/Cooling
  • Power (180 W) 78/year (0.05/KWh)
  • Cooling cost gt Power cost
  • Data center space ()
  • Hardware support contracts

27
Physical Server Costs
Virtual
  • Purchase ( Thousands)
  • Power/Cooling
  • Power (180 W) 78/year (0.05/KWh)
  • Cooling cost gt Power cost
  • Data center space ()
  • Hardware support contracts

28
Virtual Server Costs
  • Most costs amortized over VMs
  • Additional cost of VMware licenses

29
Virtual Server Costs
  • Production VM
  • 1 GHz CPU
  • 2 GB RAM
  • 50 GB Disk
  • 250/year
  • Test/Dev VM
  • 250 MHZ
  • 500 MB
  • 50 GB Disk
  • 150/year

30
Future
  • Server Consolidation
  • Greater than 80 virtualized (3 years)
  • New servers virtualized by default
  • VMware or zones
  • Faster deployment
  • Disaster recovery

31
Campus Virtualization
  • Early stages
  • Virtual hosting in CITES data center
  • Partners
  • College of Education
  • ATLAS

32
Benefits
  • Transparent redundancy
  • Fast provisioning
  • Efficient use of data center space
  • Low barrier to entry
