DirectAccess, introduced in Windows Server 2008 R2, is a remote access feature allowing connectivity to corporate network resources without the requirement of Virtual Private Network (VPN) connections. DirectAccess at the time only supported domain-joined Windows 7 Enterprise and Windows 7 Ultimate edition clients. Windows Routing and Remote Access Server (RRAS) will continue to provide traditional VPN connectivity for legacy clients, non-domain joined clients, third party VPN clients and site-to-site server connections. RRAS in Windows Server 2008 R2 must be deployed and managed separately from DirectAccess as it cannot coexist on the same edge server. In 2012, DirectAccess offered with Windows Server 2012 R2 combines the feature and the RRAS role service into a new unified server role. This new Remote Access role allows for centralized configuration, administration, and monitoring of both VPN-based remote access services and DirectAccess.  Windows Server 2012 R2 DirectAccess a...

Maximum supported configuration for Hyper-V VMs? Microsoft focused on developing Hyper-V to further extend its maximum supported configurations in Windows Server 2012. The latest version supports more memory and virtual processors, and has new features to compete with leading virtualization vendors, such as VMware. This all means Microsoft Hyper-V virtual machines (VMs) in Windows Server 2012 are more scalable than in previous versions. Memory: Hyper-V virtual machines can be configured with a maximum of 1 TB of memory. It is important to note that Hyper-V hosts must have more than 1 TB of RAM available before the VMs can be configured. Since Windows Server 2012 hosts support up to 4 TB of memory, it is now possible to configure VMs with 1 TB of RAM. Virtual processors: Hyper-V allows you to configure a maximum of 64 virtual processors (vCPUs) for a VM. Windows Server 2012 and 2012 R2 hosts support 2,048 vCPUs. Maximum hard-disk size:  For Hyper-V VMs using VHD files, a...
