67 server environments exclusively through command- line instructions. (See "Command Central" at right.) Windows Server 2012 also continues to offer Server Manager for less complex server environments and for IT administrators who prefer a graphical user interface (GUI) to command-line instructions to launch and maintain servers. Tulloch says the new Server Manager is the right option for managing a few dozen servers. "If you want to deploy Remote Desktop Services or DirectAccess, the new Server Manager guides you through the process, making it a lot easier than before," he says. Unlike with previous versions, administrators can now use it to control multiple servers at once. "I can see all the servers I manage within a single console," Desai says. "In the past, I could manage more than one server but only by manually connecting to each server as I needed to make changes." Expanded File Sharing Another update that is getting attention is Windows Server 2012's expanded Server Message Block network communication protocol. Known as SMB 3.0, the updated Windows file sharing protocol can encrypt information to secure data transmission. It also supports Remote Direct Memory Access, which means two properly configured servers can establish memory-to-memory data transfers to reduce transmission overhead. "Microsoft is scaling Windows file sharing to be more of an enterprise play, on a par with NFS --- the Network File System, an open industry standard," Schulz says. He adds that SMB 3.0 has also been beefed up to provide better data protection and resiliency. For example, IT managers can use SMB to group multiple network interface cards together for load balancing and failovers if one of the units runs into trouble. Also known as NIC Teaming, this strategy could be performed in the past if Windows Server users added third- party tools rather than those found within the OS itself. Microsoft says IT decision-makers can now use Windows Server 2012 to store application data on continuously available SMB file shares. Known as Storage Spaces, the feature allows IT managers to use commodity-priced hard disks to create resilient pools of storage, Tulloch says. is might alleviate the need for expensive SAN devices in some cases. Microsoft says that Storage Spaces provide storage virtualization capabilities for single-node and scalable multinode implementations. Other new storage optimizations provide other benefits. " ere are some small improvements that can make a huge difference, such as not needing to take a large volume offline to run CHKDSK on it to detect and repair file system problems," Tulloch says. " at small change can save organizations hours, maybe days, of downtime for their servers." According to industry insiders, Windows Server 2012 represents a giant step forward for Microsoft. Whether a single server for a small office or a new data center environment, it can help IT managers meet an organization's unique needs. e latest version of Microsoft's PowerShell scripting environment offers something Windows Server has never had before: a command-line interface. IT analysts say command lines are the tools of choice for administrators who must manage large volumes of servers, Windows operating systems, storage resou rces and networking components throughout a data center. e reason? An administrator can write one script for recon guring servers or for performing weekly backups, for example, and then run it on any number of systems. Alternatively, someone would have to click through multiple menus in a graphical user interface (GUI). e latest edition of PowerShell also lets administrators manage multiple server roles from a single, central console. "PowerShell is the way to go if you need to manage hundreds or thousands of servers in your data center," says Mitch Tulloch, author of Introducing Windows Server 2012. " e key here is automation that saves you time and, of course, money. So if you need to manage 100 Hyper-V hosts in a hosting environment, use PowerShell." Some analysts note that PowerShell's command line isn't only for large organizations with hundreds of servers. "It may also be important for small and mid-sized organizations, which tend to have limited resources because it eases the desk-side management burden," says Anil Desai, an independent IT consultant.
