  2. 2. Microsoft Virtualization Strategy<br />Best TCO/ROI<br />Data center to desktop<br />It’s the Platform you know<br />End-to-End Management <br />1/3 the price up front<br />Key feature of platform<br />Full range of products & solutions<br />Physical and Virtual & Cross-hypervisor<br />Significant Savings<br />Tools you know<br />Interoperability<br />Large partner eco-system<br />Lower ongoing costs<br />

  6. 6. Better flexibilityLive MigrationCluster Shared VolumesHot Add/remove of StorageProcessor Compatabiltiy Mode<br />
  7. 7. Live Migration<br />Overview<br />Moving a virtual machine from one server to another without loss of service<br />Benefits<br />Enables new scenarios<br />Load balancing VMs for power<br />Load balancing VMs for CPU<br />Upgrade of host hardware and maintenance <br />
  8. 8. Cluster Share Volumes: Migration & Storage<br />NEW Cluster Shared Volumes (CSV) in Windows Server 2008 R2<br />Overview<br />CSV provides a single consistent file name space; All Windows Server 2008 R2 Server servers see the same storage<br />Benefits<br />Easy setup; Uses NTFS<br />No reformatting SANs<br />Create one big data store<br />No more drive letter problems<br />Existing tools just work<br />Highly recommended for live migration scenarios<br />
  9. 9. Cluster Shared Volumes<br />All servers “see” the same storage <br />
  10. 10. Hot Add/Remove Storage<br />Overview<br />Add and remove VHD and pass-through disks to a running VM without requiring a reboot. <br />Hot-add/remove disk applies to VHDs and pass-through disks attached to the virtual SCSI controller<br />Benefits<br />Enables storage growth in VMs without downtime<br />Enables additional datacenter backup scenarios<br />Enables new SQL/Exchange scenarios<br />
  11. 11. Processor Compatibility Mode<br />Overview<br />Allows live migration across different CPU versions within the same processor family (i.e. Intel-to-Intel and AMD-to-AMD).<br />Does NOT enable cross platform from Intel to AMD or vice versa.<br />Configure compatibility on a per-VM basis.<br />Abstracts the VM down to the lowest common denominator in terms of instruction sets available to the VM. <br />Benefits<br />Provides a great deal of migration flexibility within clusters.<br />Enables migration across a broader range of Hyper-V host hardware.<br />No specific hardware requirements needed.<br />
  12. 12. Improved performanceSecond Level Address Translation (SLAT)TCP Offload supportVirtual Machine Queue (VMQ) Jumbo Frame Support<br />
  13. 13. Second Level Address Translation (SLAT)New Processor Feature Support<br />Overview<br />Uses new processor features to improve performance and reduce load on Windows Hypervisor<br />AMD: Nested Page Tables (NPT)<br />Intel: Extended Page Tables (EPT)<br />Benefits<br />Improve memory management performance<br />Reduce in memory copies<br />Memory usage will decrease from ~5% to 1% of total physical memory<br />Most improvement with large working sets (TS/SQL)<br />
  14. 14. VM Chimney (TCP Offload Support)<br />Overview<br />TCP/IP traffic in a VM can be offloaded to a physical NIC on the host computer.<br />Benefits<br />Reduce CPU burden<br />Networking offload to improve performance<br />Live Migration is fully supported with Full TCP Offload <br />Cautions: <br />Not all applications benefit from Chimney<br />Works best for long-lived connections with large data transfers <br />Applications with pre-posted buffers<br />Chimney capable hardware supports a fixed number of offloaded connections – shared between all VMs<br />
  15. 15. Virtual Machine Queue (VMQ)<br />Overview<br />NIC can DMA packets directly into VM memory<br />VM Device buffer gets assigned to one of the queues<br />Avoids packet copies in the VSP<br />Avoids route lookup in the virtual switch (VMQ Queue ID)<br />Allows the NIC to essentially appear as multiple NICs on the physical host (queues)<br />Best performance gains seen on 10G NICs (highly recommended)<br />Benefits<br />Host no longer has device DMA data in its own buffer resulting in a shorter path length for I/O (performance gain)<br />
  16. 16. Jumbo Frame Support<br />Overview<br />Enables 6x larger payload per packet<br />Ethernet frames &gt;1,500 bytes<br />Ad hoc standard is ~9k<br />Benefits<br />Improves throughput<br />Reduce CPU utilization of large file transfers<br />
  17. 17. Greater Scalability64 logical processor supportCore Parking<br />
  18. 18. 64 Logical Processor Support<br />Overview<br />Provides Hyper-V the ability to utilizesup to 64 of the logical processor pool presented to Windows Server 2008 R2<br />Benefits<br />Significantly increases host server density<br />Easily provide multiple processers per virtual machine<br />
  19. 19. Core Parking<br />Overview<br />Scheduling virtual machines on a single server for density as opposed to dispersion<br />This allows “park/sleep” cores by putting them in deep C states<br />Benefits<br />Significantly enhances Green IT by being able to reduce power required for CPUs<br />
  20. 20. תיאור תהליך אפיון ללקוח<br />Asaf Nakash<br />Project Manager<br />Dario IT Solutions<br />054-9700780<br /><br />
  21. 21. תיאור תהליך האפיון<br />ביצוע פגישת אפיון לפתרון, תיאום ציפיות ולמידת המצב הקיים.<br />התקנת כלי סטטיסטיקה ואיסוף נתונים במשך שבועיים.<br />עיבוד הנתונים<br />יצירת שני מסמכים:<br />מסמך אפיון פתרון המשלב טכנולוגיות של וירטואליזציה ו-greenIT.<br />מסמך סיכום עלויות (TCO) והחזר השקעה (ROI)<br />
  22. 22. סיפור לקוח - מצב קיים<br />ללקוח 36 שרתים<br />רובם המוחלט של השרתים הם שרתים פיזיים<br />הלקוח משלם 290$ לשנה לחוזה שירות לשרתים שאינם באחריות<br />גיל השרתים הממוצע של הלקוח הוא 2.5 שנים<br />
  23. 23. מצב קיים – שרתים<br />
  24. 24. קצת על חישוב עלות חשמל<br />שרת צורך בממוצע בשנה כ-5000 kWh, עלות kWh הינה 0.1$ כלומר עלות חשמל לשרת לשנה הינה 500$<br />עלות הקירור של השרת, כשבאים לחשב עלות קירור מעריכים כ-0.8 kWh לכל 1 kWh, כלומר עוד 400$ לשרת<br />
  25. 25. מצב קיים – ריכוז עלויות לאחר שנה<br />סה&quot;כ הוצאות בשנה זו 73,130 USD<br />
  26. 26. עיבוד נתונים<br />ממוצע לשרת<br />סה&quot;כ כוח מחשוב נדרש<br />
