My company is looking to try et virtualize tous our servers, et we are trying to figure out si virtualizing active directory is a good idea. Is it even something that can be done, et si so are there tout drawbacks to having it setup this way. My network is setup avec multiple physical servers, multiple virtual servers, et a SAN.
If you need tout more information, please let me know.
Virtualisation d'Active Directory
Re: Virtualisation d'Active Directory
Microsoft [recommends maintaining at least one physical domain controller](http://technet.microsoft.com/en-us/library/virtual_active_directory_domain_controller_virtualization_hyperv(WS.10).aspx#bkmk1_planning_to_virtualize_domain_controllers) in chaque domain.
For le plus environments, this ne need to be très much of a server. Even a [64-bit dual-core rackmount Atom server](http://www.newegg.com/Product/Product.aspx?Item=N82E16816101364), consuming 25 watts of power et costing less than $500 quand configured avec 4GB of RAM et a pair of 2.5" hard drives in RAID1, can provide a très serviceable physical domain controller/DNS/DHCP server running Server 2008 R2.
The main real-world benefit of toujours maintaining a physical domain controller is to prevent "cold start" issues quand restarting votre virtualized environment après updates/upgrades, power outages, etc. Ceci est especially relevant si you use Hyper-V servers as virtualization hosts, as these machines will expect to be able to find a domain controller at startup.
