Windows Server Enterprise The Enterprise edition will be indicated for large companies running heavy applications like SQL Server or Exchange Server , these applications will require more memory than the Standard edition supports. The wise thing to do is put the Standard and Enterprise working together when these demands exist, the Standard running the most plain papers and Enterprise applications running the heavier ones or working in failover cluster.
Windows Server Datacenter The Datacenter edition is intended only to large enterprise market , the main difference from the Enterprise is on the number of virtual machines that can be used with a single license is unlimited. Normally a license of the Datacenter will be associated with a physical server in the form of OEM, meaning that they can be only been bought together.
Windows Server R2 is effectively the seventh generation of the Windows Server operating system. Upon initial boot, shown in Figure 1. However, because Windows Server R2 is more of a business functional operating system than a consumer or user operating system, things like the cute Windows Aero 3D interface are not installed by default, and the multimedia features found in the Windows 7 Home or Ultimate versions of the operating system are also not installed and enabled by default.
Figure 1. Under the surface, though, and covered through the pages of this chapter are the new technologies and capabilities built in to Windows Server R2.
These are technologies that make the new operating system faster, more reliable, and do more things—but they aren't features that you have to install or configure. Effectively, the operating system has a worker thread that runs in the background, which makes corrections to the file system when NTFS detects a corrupt file or directory. In the past when there was a file system problem, you typically had to reboot the server for chkdsk to run and clean up file and directory corrupt errors.
This self-healing function is not something you will ever see running; however, it is an added capability under the hood in Windows Server R2 that keeps the operating system running reliably and with fewer system problems. SMB2 is a protocol that handles the transfer of files between systems.
Effectively, SMB2 compresses file communications and, through a larger communications buffer, is able to reduce the number of round-trips needed when transmitting data between systems. For the old-timers reading this chapter, it is analogous to the difference between the copy command and the xcopy command in DOS. The copy command reads, writes, reads, writes information. The xcopy command reads, reads, reads information and then writes, writes, writes the information.
Because more information is read into a buffer and transferred in bulk, the information is transmitted significantly faster. The performance improvement is very noticeable in wide area network WAN situations on networks with high latency.
Because a typical transfer of files requires short read and write segments of data, a file could take minutes to transfer across a WAN that can transfer in seconds between SMB2-connected systems because the round-trip chatter is drastically reduced. Hyper-V is a technology built in to the core of the operating system in Windows Server and expanded in Windows Server R2 that greatly enhances the performance and capabilities of server virtualization in a Windows environment.
In the past, virtual server software sat on top of the network operating system and each guest session was dependent on many shared components of the operating system. Hyper-V provides a very thin layer between the hardware abstract layer of the system and the operating system that provides guest sessions in a virtualized environment to communicate directly with the hardware layer of the system.
Without having the host operating system in the way, guest sessions can perform significantly faster than in the past, and guest sessions can operate independent of the host operating system in terms of better reliability from eliminating host operating system bottlenecks. Hyper-V and server virtualization is covered in more detail in Chapter 37, "Deploying and Using Windows Virtualization.
A technology enhanced in the core Windows Server R2 operating system is a power-management technology called core parking.
Normally, when a multicore server runs, all cores on all processors run at the highest speed possible, regardless of whether the server is being utilized. For organizations that need high capacity during the weekdays when employees are working, that means their systems are effectively idle during evenings and weekends, or more than two thirds of the time, yet consuming power and expending heat. With core parking, servers with the latest processors that recognize core parking protocols will shut down cores on a system when not in use.
So, on a core server, if only 2 cores are needed, the other 14 cores are powered off automatically. This dramatically improves power management and decreases the cost of operations of server systems. As much as there have been significant improvements in Windows Server R2 under the hood that greatly enhance the performance, reliability, and scalability of Windows Server R2 in the enterprise, Windows servers have always been exceptional application servers hosting critical business applications for organizations.
Windows Server R2 continues the tradition of the operating system being an application server with common server roles being included in the operating system.
