1. What’s new in Hyper-V in Windows Server 2012 (Part 1) Stu Fox (@stufox) Technical Specialist, Microsoft NZ VIR312

5. Scale-up Workloads LEARN MORE

6. Scale Scale isn’t just more virtual processors Live Migration should just work No tradeoffs Performance must increase with cores Maximize your investment Virtualise workloads considered “non-virtualisable” Let’s build the best cloud together

As many as hardware will allow. Live Storage MigrationNo. Quick Storage Migration via SCVMM Yes, with no limits. As many as hardware will allow. Servers in a Cluster16 64 VP:LP Ratio8:18:1 for Server 12:1 for Client (VDI) No limits. As many as hardware will allow.

8. 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 NUMA node 1NUMA node 2

9. This is optimal… Memory allocation and thread allocations within the same NUMA node Memory populated in each NUMA node Host NUMA Memory Processors NUMA node 1NUMA node 2 Memory Processors NUMA node 3NUMA node 4

10. 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 NUMA node 1NUMA node 2 Memory Processors NUMA node 3NUMA node 4 Host NUMA

11. 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 vNUMA node AvNUMA node BvNUMA node AvNUMA node B NUMA node 1NUMA node 2NUMA node 3NUMA node 4

12. Storage

13. Leverage storage array capabilities Maximize your investment Native access to SANs from VMs No tradeoffs Help reduce the cost of storage For workloads that don’t require a SAN Highly Scalable Virtual Disks Big data is here

23. Hyper-V: Over 1 Millions IOPs from a Single VM Industry Leading IO Performance VM storage performance on par with native Performance scales linearly with increase in virtual processors Windows Server 2012 Hyper-V can virtualise over 99% of the world’s SQL Server.

24. Securing Data at Rest

26. Clustering & Resiliency

27. VMs Need Access to Fibre Channel SANs We have apps and data there… Legacy Apps that don’t support Clustering Let’s improve availability of those apps too Ease integration with SAN replication/snapshotting Make it all work. Highly Scalable Virtual Disks Big data.
