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

Scale-up Workloads LEARN MORE

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

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

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

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

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

Storage

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

Clustering & Resiliency

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.
