  3. Agenda

  4. “What’s on my mind?”

  5. About the CoE • College of Education made up of 6 departments across 3 buildings (GA, GH, AN) • Currently have ~ 450 Mac machines • Roughly ½ are installed in labs • Most common machine type is theiMac • MacBook/MacBook Pro/MacBook Air are common as well

  6. How did we get here? • 1980’s Apple II and a Mac • Some continued lab use and faculty adoption until 2008 • Supported with conditions • Fully supported Mac starting in 2008 (OSX and Hardware)

  7. What allowed for the change? • Purchase of equipment for CoE Technology Services (CEDUHelp) staff to use • Training / Certification • Purchase of consulting • R & D Time • Support from Associate Dean

  8. Key Technology Building Blocks

  9. Imaging Solutions • Many Available • Small installations • Target Disk Mode (Option-T) • Disk Utilities • Larger installations • Deploy Studio (deploystudio.com) – It’s free • Can handle OSX and Windows imaging • Casper (jamfsoftware.com)

  10. Dual Boot • Boot Camp technology allows for Mac to run OSX and Windows on same machine • Choose OS with an Option Boot • Can use a boot manager • BootPicker (no longer being developed) • rEFIt(no longer being developed) • rEFInd • Changing OS requires a reboot

  11. Integration into Enterprise • Ensure that network shares allow for AFP • May require additional configuration on Mac • Machines can be bound to AD • TEST Carefully!!!!!!!!!

  12. Lessons Learned • Mac aren’t immune from hardware failures • Keyboards and Mice can cause problems • Dual boot issues • Feel issues • Do you want wireless • Talking to people at Apple can be difficult • Official documentation is ….. • Unix is your friend • Remember it’s the data that’s key not hardware

  13. Most Important Take Away • Learn to avoid the “Oooh…. Shiny effect” • Needs analysis is important • Do you want to support Dual Boot for everyone? • Consider VM for Windows needs (we often use VirtualBox)

  14. News in a Flash • What’s Cool about VM’s – Fred Williams • IT Training Needs – Cindy Kozumplik • Welcome Days – Maria Barnes • OnBase in Action – Craig Williams

  15. What’s Cool about VM’s VM Vivarium http://xkcd.com/350/

  16. What’s Cool about VM’s • 10 cool things about VM’s and 2 announcements in under 10 minutes • (not in coolness order)

  17. OVF and OVA What are they? Virtual machine encapsulation formats OVA = Open Virtual Application All information required is encapsulated OVF = Open Virtualization Format or Open VM Format Collection of a few files containing all required information

  18. OVF and OVA Why are they cool? Optimized for distribution Optimized for simple automated repeatable deployment Supports both single and multiple vm configurations Portable/independent VM Packaging that does not rely on specific host platform, hypervisor or guest OS Extensible and Open Standard Developed by: Vmware, CISCO, Citrix, HP, Hitachi, IBM, Intel, Microsoft, Netapp, Oracle, Others

  19. P2V V2V V2P What are they? P2V = Physical to Virtual Migration V2V = Virtual to Virtual Migration V2P = Virtual to Physical Migration

  20. P2V V2V V2P Why is P2V cool?

  21. P2V V2V V2P Why is V2V cool?

  22. P2V V2V V2P V2P is NOT cool

  23. Snapshots What are they? Snapshots preserve the state and data of a virtual machine at a specific point in time.

  24. Snapshots Why are they cool? Patch Testing Testing Software Updates/Upgrades New Software Testing Restore Testing Security Testing 3rd Party Backup/Replication

  25. High Availability What is it? High Availability is a hypervisor feature that in the event of physical server failure, affected virtual machines are automatically restarted on other production servers with spare capacity.

  26. Fault Tolerance What is it? Fault Tolerance provides continuous availability for applications in the event of server failures by creating a live shadow instance of a virtual machine that is always up-to-date with the primary virtual machine.

  27. High Availability / Fault Tolerance Why are they cool? Minimizes unplanned downtime due to hardware failure so you can sleep through the night and fix it in the morning.

  28. VMotion What is it? VMotion is a key enabling technology for creating the dynamic, automated, and self-optimizing datacenter. How does it work? 1. Shadow VM created on the destination host. 2. Copy each memory page from the source to the destination via the vMotion network. This is known as preCopy. 3. Perform another pass over the VM’s memory, copying any pages that changed during the last preCopy iteration. 4. Continue this iterative memory copying until no changed pages (outstanding to be-copied pages) remain. Stun the VM on the source and resume it on the destination. There is vmotion, storage vmotion and enhanced vmotion.

  29. VMotion What are they?

  30. VMotion Why is it cool?

  31. Physical Device Access What is it? VMDirectPath The virtual machine takes full control of the device. As it has full control of this hardware component attached to the server, it cannot be vMotioned to a different server. In addition, other servers do not have the ability to remotely access the device or hardware. USB device passthrough This option allows you to redirect I/O to or from a USB device for virtual machines. The device is managed by the VMkernel, allowing the attachment of USB devices to virtual machines live, and maintaining vMotion capability.

  32. Physical Device Access • Why is it cool? • USB-IP to Solve Sound Card Requirement for VM’s and Remote Audio Inputs • Current Situation: • Four weather radios have their audio outputs input to sound cards on separate standalone PC’s (Personal Computers) in the client’s office. Management requires the PC’s be removed and replaced with VM’s (Virtual Machines) running on an ESX Host in a Centralized Server Room. • Challenges: • The VM’s do not have sound cards, because the ESX Hosts do not have sound cards. • The Weather Radios may need to be external to the Centralized Server Room because of signal interference, wire management, etc. • A way is required to broadcast the weather radio’s input signal to the PC out to the internet. • Solution: • USB-IP allows USB devices to be plugged in and utilized by remote PC’s or VM’s.

  33. Flexible Cores per Socket What is it? Can define up to the total amount of cores on a server to a single virtual socket in a vm. Why is it cool? Attain required performance and maintain license compliance for guest os or application.

  34. Dynamic Resources What is it? Can hot/cold add/remove devices and resources from VM’s.

  35. Dynamic Resources Why is it cool? For rapid realtime, or planned downtime, scale up For scale down minimum workload power savings, overnight consolidation, power down hosts For better use of underlying hardware for dynamic workloads

  36. Provisioning Resources What is it? We can over provision ram/cpu/disk. We can thin provision disk. Why is it cool? Enables us to maximize hardware ROI by driving hardware utilization

  37. Provisioning Resources Virtual Machine Maximums Virtual CPUs per virtual machine (Virtual SMP) 64 RAM per virtual machine 1TB Virtual SCSI adapters per virtual machine 4 Virtual SCSI targets per virtual SCSI adapter 152 Virtual SCSI targets per virtual machine 60 Virtual Disks per virtual machine (PVSCSI) 60 Virtual disk size 2TB minus 512 bytes IDE controllers per virtual machine 13 IDE devices per virtual machine 44 Floppy controllers per virtual machine 1 Floppy devices per virtual machine 25 Virtual NICs per virtual machine 106 USB controllers per virtual machine 17 USB devices connected to a virtual machine 208 Parallel ports per virtual machine 3 Serial ports per virtual machine 4
