Hyper-V Infrastructure

  1. 1. Microsoft Virtual Academy
  2. 2. Microsoft Virtual Academy First Half Second Half (01) Introduction to Microsoft Virtualization (05) Hyper-V Management (02) Hyper-V Infrastructure (06) Hyper-V High Availability and Live Migration (03) Hyper-V Networking (07) Integration with System Center 2012 Virtual Machine Manager (04) Hyper-V Storage (08) Integration with Other System Center 2012 Components ** MEAL BREAK **
  3. 3. Microsoft Virtual Academy
  4. 4. Processor Virtualization Local storage RAM All hardware components should have a Window Server logo
  5. 5. • NUMA (Non-uniform memory access) • Helps hosts scale up the number of cores and memory access • Partitions cores and memory into “nodes” • Allocation and latency depends on the memory location relative to a processor • High performance applications detect NUMA and minimize cross-node memory access Host NUMA Memory Processors NUMAnode1 NUMAnode2
  6. 6. • This is optimal… • Memory allocation and thread allocations within the same NUMA node • Memory populated in each NUMA node Host NUMA Memory Processors NUMAnode1 NUMAnode2 Memory Processors NUMAnode3 NUMAnode4
  7. 7. • This isn’t optimal… • System is imbalanced • Memory allocation and thread allocations across different NUMA nodes • Multiple node hops • NUMA Node 2 has an odd number of DIMMS • NUMA Node 3 doesn’t have enough • NUMA Node 4 has no local memory (worst case) Memory Processors NUMAnode1 NUMAnode2 Memory Processors NUMAnode3 NUMAnode4 Host NUMA
  8. 8. • Guest NUMA • Presenting NUMA topology within VM • Guest operating systems & apps can make intelligent NUMA decisions about thread and memory allocation • Guest NUMA nodes are aligned with host resources • Policy driven per host – best effort, or force alignment vNUMAnodeA vNUMAnodeB vNUMAnodeA vNUMAnodeB NUMAnode1 NUMAnode2 NUMAnode3 NUMAnode4
  9. 9. Windows Server 2008 Windows Server 2008 R2 Windows Server 2012 HW Logical Processor Support 16 LPs 64 LPs 320 LPs Physical Memory Support 1 TB 1 TB 4 TB Cluster Scale 16 Nodes up to 1000 VMs 16 Nodes up to 1000 VMs 64 Nodes up to 8000 VMs Virtual Machine Processor Support Up to 4 VPs Up to 4 VPs Up to 64 VPs VM Memory Up to 64 GB Up to 64 GB Up to 1 TB Live Migration Yes, one at a time Yes, one at a time Yes, with no limits. As many as hardware will allow. Live Storage Migration No. Quick Storage Migration via SCVMM No. Quick Storage Migration via SCVMM Yes, with no limits. As many as hardware will allow. Servers in a Cluster 16 16 64 VP:LP Ratio 8:1 8:1 for Server 12:1 for Client (VDI) No limits. As many as hardware will allow.
  10. 10. Startup RAM Maximum RAM Memory Buffer Memory Weight (aka Memory Priority)
  11. 11. T = 0 T = 15 T = 30 T = 0 T = 15 T = 30 2 GB 4 GB 6 GB 8 GB Virtual Machines Memory Settings Total System Memory Memory in Use by VMs 8 GB 3 GB Physical Memory Used 37.5 % 3 VMs started Finance VM Sales VM Engineering VM
  12. 12. T = 0 T = 15 T = 30 T = 0 T = 15 T = 30 2 GB 4 GB 6 GB 8 GB Virtual Machines Memory Settings Total System Memory Memory in Use by VMs 8 GB 6 GB Physical Memory Used 75 % 3 VMs started Finance starts reports Engineering starts an analysis job Finance VM Sales VM Engineering VM
  13. 13. Memory recovered to allow Service VM 3 VMs started Finance report finished Engineering analysis running IT starts a Service VM Finance starts reports Engineering starts an analysis job Engineering reaches max allocation T = 0 T = 15 T = 30 T = 0 T = 15 T = 30 Virtual Machines Memory Settings Total System Memory Memory in Use by VMs 8 GB 7.5 GB Physical Memory Used 94 % Finance VM Sales VM Engineering VM Service VM 2 GB 4 GB 6 GB 8 GB
  14. 14. Most OSes require more memory during boot and will use less when idle Customers wanted more configuration flexibility
  15. 15. Assume that Sales and Service VM are Restarted Finance & Engineering Grab all available memory T = 0 T = 15 T = 30 Virtual Machines Memory Settings Total System Memory 8 GB Finance VM Sales VM Engineering VM Service VM 2 GB 4 GB 6 GB 8 GB
  16. 16. Smart Paging designed to ensure VMs always restart When restarting VMs: Why only on VM Reset? When starting new VMs:
  17. 17. Q: Are there any recommendations for types of disks or storage subsystems (SATA, SAS, SSD) for Hyper-V Smart Paging? A: Dynamic Memory has been architected so that in the vast majority of cases, Hyper-V Smart Paging is rarely used and, if used, only on a temporary basis. Thus, the need for special high end storage isn’t needed and Smart Paging will take advantage of whatever storage is presented.

  30. 30. Enterprise-class, Microsoft hypervisor Standalone Hyper-V Free ISO download from Microsoft.com website Designed for remote management Contains all Hyper-V features
  31. 31. Is this an evaluation version? Is their Activation? Is this supported in production? Does Hyper-V Server have reduced/limited scale? Is System Center required for Live Migration or Live Storage Migrate VMs?
  32. 32. Is clustering included with Hyper-V Server 2012? Does Hyper-V Server include Live Migration? Shared Nothing Live Migration? Does this include the new Extensible Switch? Does this include Hyper-V Replica?
  33. 33.

  34. 34. • There are many considerations for planning the server, storage, networking, software, and security • Virtualization hosts will have different requirements than infrastructure servers • Consider virtualization rights when selecting the host OS • Use the Microsoft Assessment and Planning Toolkit (MAP) for guidance
