Dynamic MemoryRemoteFX

How much memory does a web server require ?

How much memory does a domain controller require ?

Vendor said “Recommended 2GB”

Access application slow !

System overloaded when peak time !

2GB of memory not sufficient as suggested

by vendor!

Application Memory Utilization

Windows Server 2008 R2 SP1

Microsoft RemoteFX leverages the power of virtualized graphics resources and advanced codecs to recreate the fidelity of hardware-assisted graphics acceleration, including support for 3D content and Windows Aero, on a remote user’s device. This allows for a local-like, remote

Dynamic Memory allows the allocation of a range of memory (min and max) to individual VMs, enabling the system to dynamically adjust the VM’s memory usage based on demand. This provides more consistency in system performance enabling better manageability for administrators

How to Upgrade?

Backup first – High priority !Ensure Virtual Machine are ready for the update

Completely shutdown. No Saved State VMMerge Snapshot

Update the Host to SP1 RCUpdate the VM

Integration Services

Enable Dynamic Memory

Make sure the Virtual Machine is not running.Startup : Min 512 MB

Maximum: default 64 GB

Memory BufferIdeal target memory value is constantly change.Default is set to 20%

Memory Weight

Memory weight determine who will get the memory. By default, all VM are created equal in term of memory prioritization.Rules of thumb:-

Higher Priority will get memory 1st

Taken from Lower Priority VM

Reserve Parent PartitionConfigure Hyper V parent partition to avoid freezes when Dynamic Memory VM’s use all RAM.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ Virtualization

RED_DWORD valueName = MemoryReserveSetting = amount of MB to reserve for the parent partition, e.g. 2GB RAM
