Helping You Cloud Optimize Your BusinessThe Microsoft Hybrid Cloud
Building your own cloud just got a lot easier with
Windows Server 2012.
Scale-up Workloads
[VIR413] Hyper-V Performance, Scale & Architecture Changes

Mission Critical Workloads
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

Scaling up: Physical NUMANUMA (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 1 NUMA node 2
Scaling up: Physical NUMA
This is optimal…Memory allocation and thread allocations within the same NUMA node
Memory populated in each NUMA node
Host NUMA

NUMA node 1 NUMA node 2
Memory
Processors
NUMA node 3 NUMA node 4
Scaling up: Physical NUMAThis 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)

Scaling Up: Guest NUMAGuest 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
