  • HA: High Availability Vmotion: used in maintenance, DRS DRS: equal rights for all!
  • Transcript

    • 1. Lean Green VM Technology Jeremy Allison and Jeremy Baca CSU Server Managers Sandia is a multiprogram laboratory operated by Sandia Corporation, a Lockheed Martin Company for the United States Department of Energy’s National Nuclear Security Administration under contract DE-AC04-94AL85000.
    • 2.
        • A Virtual Machine is software that creates a virtualized environment between the computer platform and its operating system, so that the end user can operate software on an abstract machine.
      What is VM?
    • 3. Types of VM technology
      • Emulation
        • Virtual PC for Power PC based Mac
      • Paravirtualization
        • XEN
      • “Full Virtualization”
        • VMWare, Parallels
    • 4. VMWare ESX Server
      • “Bare metal” virtualization
        • Overhead of host OS kept to a minimum
        • Takes advantage of Intel and AMD virtualization
      • VMFS
        • Cluster file system allowing distributed storage utilization
      • RAM Over-Commitment
        • Hedging your memory bet
    • 5.
      • Memory ballooning
        • “… artificially induces memory pressure within idle virtual machines, forcing them to use their own paging areas and release memory for active virtual machines “
      • Virtual Machine deployment
        • Cloning
        • VM Templates
        • Sysprep integration
      • Consolidated Backup
        • Centralized backups anytime of day
      • VMWare Converter
        • Convert running machines to virtual machines
    • 6. ESX Architecture The cluster behind the curtain
    • 7. VirtualCenter Server
      • HA
        • In the event of host failure VI can gracefully shutdown VM’s on the failed host and reboot them on a running host
      • VMotion
        • Can move a running machine from one host to another without interuption
      • DRS
        • Uses Vmotion to dynamically manager host resources by balancing resource utilization across hosts
    • 8. ESX Host Server
      • Virtualized CPU’s
        • Allows up to 4 virtual CPU's to be assigned to a machine
      • Memory
    • 9. Storage
      • VM Data stores
        • VMFS
          • Clustered file system
          • LUN’s can be dynamically added
        • Supports local drives, NFS, ISCSI and Fiber Channel
    • 10. Virtual Network
      • VSwitch
        • Works like a layer 2 switch
      • Port Groups
        • Traffic Shaping
        • NIC teaming for throughput and redundancy
    • 11.  
    • 12. Things to Consider Avoiding a big cluster
    • 13.
      • Candidates for virtualization
        • Current server requirements
        • Current CPU, Memory and Network Utilization
        • Disk I/O
        • Projected Growth in storage and utilization
    • 14. More to consider
      • Number of Host servers
      • Memory Requirements
      • Amount and type of storage
        • Fiber Channel
        • ISCSI
        • NFS
        • Local Storage
    • 15. Why?
      • Money
        • Reduced power costs
        • Reduced cooling costs
        • Reduced cost on hardware refresh
      • Greener datacenter
        • Reduced power consumption
        • Reduced cooling requirements
        • Reduced Hardware refresh waste
        • The public likes green
    • 16. Our Current Setup What a Cluster!
    • 17. Virtual Infrastructure Server
      • Power Edge 2650
        • 1 GB of RAM
        • Xeon 2.4 GHz Processor
        • Windows Server 2003 sp2
        • Virtual Infrastructure server 2.01
        • Responsible for HA, DRS and day to day business
    • 18. ESX Host Servers
      • Two Power Edge 2850’s
        • 12 GB of RAM each
        • Dual, Dual core Xeon processors at 2.8Ghz each
        • 2 onboard Gigabit NIC’s
        • 2 dual port Gigabit NIC’s
        • 4 73 GB 15k RPM SCSI HDD’s
          • Raid 5 with one hot swap
        • ESX 3.01
    • 19. Storage Server
      • Power Edge 2950
        • 2 GB of RAM
        • Dual Core 64 bit Xeon at 3.0 GHz
        • 6 250 GB SATA HDD’s
          • RAID 5 with one hot swap
        • Windows Server 2003 Storage Server 64bit
    • 20. Impressions
    • 21.
      • NFS…not good except for ISO image storage
      • ISCSI good and gains VMFS and consolidated backup
      • Fiber Channel is good and the suggested configuration
      • Updating is a bit tedious
      • Very easy to deploy a new server
      • Permission control on VM’s is handy
      • Once setup it seems very solid
      • Alerts can be setup for a number if situations
    • 22.
      • Redundancy is important since you now have all of your eggs in only a few baskets
      • VM Converter is down right cool
      • Problems with two factor
        • VM Converter has limitations
        • VI server requires Cryptocard login
      • Initial ESX server build only takes about 20 minutes…but then the patching begins
      • Familiarity with Linux, Perl and bash a plus
      • automating much of the day to day work with scripting probably a necessity
    • 23. Things to do
    • 24.
      • ISCSI mirroring to second offsite storage server
      • Setup Consolidated backup
      • Script Updates
      • Add adapters to Storage server
    • 25. Questions
