• NUMA (Non-uniform memory
NUMA node 1

access)
Processors
• 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
Memory
• High performance applications
detect NUMA and minimize crossnode memory access

• This is optimal…

• Memory allocation and
thread allocations within

• This isn’t optimal…
• System is imbalanced

•
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

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

Assume that Sales and
Service VM are Restarted
Smart Paging designed to ensure VMs always restart
When restarting VMs:
Why only on VM Reset?
When starting new VMs:
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.

Virtual Machine Memory Support:
• 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)
