Do MUCH More with Less Presented by: Jon Farley 2W Technologies
What is Virtualization? ◦ Specifically Microsoft Hyper-V Why Virtualize? ◦ Because we can! Benefits – Many ◦ Reliability, Flexibility, Performance, Lower Cost Recommendations Implementing Virtualization Demonstration
2 Pieces – Hardware & Software ◦ Hardware Both AMD & Intel built-in virtualization technology Included in recent Servers & most pc’s Divides resources at the hardware-level Keeps each virtual machine isolated from other vm’s ◦ Software Microsoft’s Virtualization is called “Hyper-V” built into Windows 2008/Windows 7 Enables a “Host” server to host 1 or more VM’s Free version of Win 2008 core “Windows 2008 Hyper-V Server” to just host VM’s VM Ware Invented the concept Costs $ Separate App, not part of the Operating System
◦ Software (continued) Hosts & Guests Host would be full Win 2008 64-bit, or free Hyper-V *Strongly recommend “R2” version of Win2008 Guest VM’s could be nearly any operating system Win 2000/2003/XP/Vista/2008/7, Linux, etc. 1 Host Hyper-V Server can several VM’s 2-4,5,6… VM’s but totally depends on workload of each Be smart about it, distribute load over physical servers appropriately Separate Disk-intensive VM’s on separate physical servers Same with Processor or Network intensive VM’s Hyper-V Manager – will demo later Control & manage any HV hosts & all their VM’s Can run from Win2008/R2* server, Win 7 pc, Win Vista*
◦ Because we can & it makes good sense Hardware & Software now make it possible & affordable ◦ Get more Bang for Your Buck 1 Server can house several virtual servers Domain controller, file server Database server, V8/E9 Terminal server to host clients In the past, there was a 1-TO-1 ration between Hardware & Servers Was very expensive to split up server functions, required hardware for each Now just buy a couple extra Windows server licenses Enterprise version of 2008 allows for 1 physical host & 4 Virtual servers *About the cost of 3 individual 2008 Standards Standard allows 1 Host & 1 Virtual
What is #1 benefit? ◦ HARDWARE INDEPENDENCE!! 1 Crash away from dreaded “Blue Screen of Death” If the hardware, drives or operating system get damaged… Downtime! Very costly to business. In a virtual environment, can quickly port a VM to another physical server or even beefy PC! Very little downtime No longer tied to the hardware Another layer between VM operating systems & hardware “Removed” from hardware
Improved backups, disaster recovery ◦ Entire virtual server can be backed up w/backup commands capture backup image Or shutdown the vm & copy the.vhd file to backup disk ◦ Can easily restore entire VM if it got damaged Can Make backup copies for Test or demo use ◦ Before loading a new update, won’t damage production server Very Fast Performance ◦ No difference between virtual & physical server

Next Step -System Center Virtual Machine Manager (SCVMM) Setup a Redundant/Failover “farm” of 2 or more physical servers Centrally control all Hyper-V host servers & all VM’s Inexpensive license, maybe $500 per physical server *Very cheap for full server redundancy Allows for “Live Migration” (R2 only) Move a VM from one physical box to another with *Min downtime (2 mins. Or less)
One Server at a time ◦ Start with one ◦ Phase-out old servers, migrate to Virtual servers ◦ Make any new server virtual from day 1 P2V (Physical to Virtual) Conversions ◦ Move an existing server from old hardware to VM Retire Old, Slow, or Unstable hardware Once virtualized Can give same server more RAM, disk space Will run much faster since on fast host server Often much easier than reinstalling a entire server & all applications
Build Accordingly ◦ You can overload any server, physical or virtual Provide plenty of Memory & Disk space for all VM’s ◦ Sum of all RAM for VM’s plus 2gb or more for HV Host ◦ Have “Utility” disk partition for backups ◦ VM’s on partition by themselves Can then backup entire volume (to utility) & get an image of all VM’s Dual Quad Core processors if 2 or more VM’s ◦ Or more for large environments Multiple Network cards on host ◦ Spread network load/traffic over separate gb network connections
Show our 2W virtual servers in action Also, new 2008 “RemoteApp” ◦ Much improved Terminal Services
