Enterprise is also Server + CAL and entitles the host to one physical and up to four virtual instances, with additional features such as Fault Tolerant Memory Sync and larger memory ceilings. Datacenter is licensed under the Processor + CAL model and entitles the host to one physical and an unlimited number of virtual instances, with the largest processor, memory, and high-availability footprint.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow many Datacenter licenses do I need for a two-processor server?\u003c\/summary\u003e\n\u003cp\u003eOne Datacenter license per physical processor. A two-socket server requires two Datacenter licenses. Microsoft treats multicore and hyperthreaded processors as a single processor, regardless of the number of cores or threads.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDo I need a CAL for every user that opens a file on the server?\u003c\/summary\u003e\n\u003cp\u003eYes. A Windows Server CAL is required for every user or device that accesses server services such as file services, print services, or Active Directory authentication. The user-or-device choice is yours: User CALs are the more cost-effective model when one user connects from many devices; Device CALs are the more cost-effective model when many users share a small number of devices.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan I run Linux virtual machines on the same Datacenter host?\u003c\/summary\u003e\n\u003cp\u003eYes. Hyper-V in Windows Server 2008 R2 supports Linux guest operating systems, including SUSE Linux Enterprise Server, Red Hat Enterprise Linux, and Ubuntu. Linux virtual machines on Hyper-V do not require a Windows Server license for the guest, but the host still needs a Windows Server Datacenter license for the unlimited virtualization rights.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDoes this include SQL Server or Exchange Server?\u003c\/summary\u003e\n\u003cp\u003eNo. Windows Server 2008 R2 Datacenter is the server operating system only.
