The Future of Windows: What We Want from Win 8
Windows Home Server V2
Extended hands-on time with Microsoft's new home server OS reveals some interesting and powerful new features
We dig Windows Home Server, Microsoft’s home-oriented server operating system. It’s provided us with an easy-to-use and relatively bullet-proof means of backing up our multiple PCs, made it easy to access important files over the web, protected our shared libraries through automatic file duplication, and so much more.
But Windows Home Sever Version 1 has never been pretty to look at—we’ve long since replaced its weak media server with a third-party application, and its 32-bit code base (based on Microsoft’s Windows Server 2003) makes client restoration more awkward than it should be. While we’ve had to speculate as to the features that might be included in Windows 8, Microsoft’s follow-up to Windows Home Server has been in beta since last April.

The new Windows Home Server Launchpad runs on client machines and can start third-party apps as well as the server's Dashboard.
Here’s a high-level look at the new operating system, based on an interview with Microsoft Senior Product Manager Michael Leworthy and some quality time we’ve spent using the beta. Microsoft has not announced a target ship date, but we’re guessing WHS Version 2 (which is based on Windows Server 2008 R2) will ship in the second or perhaps third quarter of 2011.
Hardware Requirements
As with Windows Home Server Version 1, Microsoft expects most consumers will buy Version 2 (the beta version’s full name is Windows Home Server Code Name “Vail”) pre-installed on a headless computer. We expect most of our readers, however, will buy the system-builder version of the OS and install it on a cast-off machine. Either way, the minimum hardware requirements are a 1.4GHz x64 processor, 2GB of RAM, and at least one 160GB, NTFS-formatted hard drive. The server must be hardwired to your router, and a UPnP-certified router—while not required—will deliver the best experience.

Vail's Dashboard performs the same functions as the current Windows Home Server Console, but with a Windows 7 look. This version will continue to support up to 10 users, including Macs.
Where WHS Version 1 supported a maximum of five hard drives, Vail will support up to 10 (internal SATA, eSATA, USB, or FireWire). The system disk (the one on which the OS is installed) can reside outside Vail’s Drive Extender storage pool. If you’re not familiar with Microsoft’s Drive Extender technology, it’s a file-replication system that provides multi-disk redundancy to protect you from data loss in the event of a catastrophic disk failure. The system duplicates shared folders to different drives, so there’s always a backup copy. Unlike a RAID configuration, however, a Drive Extender storage pool can consist of different-size drives. And unlike a JBOD array, there are no drive letters; the capacity of all the drives is aggregated into a single pool.
Client Support
As does the current version, Vail will support a maximum of 10 users or 10 computer clients (running any combination of Windows XP SP3, Vista SP2, or Windows 7. The 64-bit version of Windows XP is not supported). The release version of Vail will support Macintosh clients out of the box, too. Client machines will run a taskbar app called Launchpad, which provides an easy way to log onto the server, access shared folders on the server, initiate manual backups, access the server’s remote website, or start the server’s Dashboard app. Launchpad will also be able to start third-party server-oriented applications.
Dashboard is a replacement for the Windows Home Server console used in WHS Version 1. It’s the primary user interface for configuring your server’s settings as well as the backup settings for each of its client machines. It’s not much different from the Windows Home Server console from a functional standpoint, but it’s a whole lot prettier.

Whether your server has one hard drive or 10, Vail will aggregate them into a contiguous pool of storage.
The OS will automatically perform block-based backups of its clients (Version 1 performed file-based backups); and for the first time, you’ll be able to back up the server, shared folders, and your client backups to an external hard drive for offsite storage. The OS has hooks for backing up to the cloud, too, but Microsoft’s Leworthy tells us the company has not decided whether or how it might expose that capability.
WHS Version 1 is capable of restoring individual files and folders, but since it’s a 32-bit OS, it’s rather clumsy when it comes to performing a bare-metal restore of a 64-bit system—since it can’t automatically restore a system’s 64-bit device drivers, you must locate them manually and copy them to a USB memory device. Vail features 64-bit code and will be able to perform a full restore using a bootable USB drive (Version 1 requires a bootable system-restore disc for each client).

Resource Monitor enables you to keep an eye on your server's workload and overall performance.
A Vail server will be able to join a Windows 7 HomeGroup, so everyone who belongs to the same home group will have access to the same shared folders. The system administrator, however, will be empowered to assign permissions to each user. Mom and Dad might have read/write access to shared photos and videos folders, for example, while the rugrats are limited to read-only access. The system administrator will also be able to monitor the health of client machines and will have the power to push Windows updates and new antivirus definitions out to them.
Media Streaming Features
The original Windows Home Server is a relatively weak media server right out of the box, needing a third-party add-on such as Twonky’s TwonkyServer or PlayOn’s PlayOn Digital Media Server to reach its full potential. Leworthy promises Vail will be different: It will not only be DLNA 1.5–compliant, it will use Microsoft’s Silverlight software to stream DRM-free media to clients on your local network and to clients on the Internet—including mobile devices.
Silverlight will also improve Windows Home Server’s remote-access feature, enabling friends and family to whom you grant access to view shared content on your server in a friendly, browser-like environment. Real-time video transcoding is fully supported, which is essential for streaming HD video to handheld devices, but not so for streaming to more powerful clients. You’ll need a relatively strong CPU in your server to pull off that trick, though—an Atom isn’t going to cut it.

Vail uses Microsoft's Silverlight and Windows Media Foundation technologies to stream media.
Vail promises to deliver a much stronger, easier to use, more feature-packed home-server OS than ever, but there’s one feature that we’re disappointed to report won’t make it: any implementation of Windows Media Center. Imagine installing Ceton’s InfiniTV CableCARD tuner into a Windows Home Server box and connecting it to your cable TV service: You’d have the ultimate DVR with the ability to stream recorded TV programs—including video from premium channels such as HBO and Showtime—to wherever you happen to be. Sadly, we don’t expect that will happen anytime in the near future, simply because the Windows Server 2008 code base lacks any of the DRM hooks that are present in Windows 7.
But when all is said and done, we can’t wait to build a new Vail-based server—and we’re even more excited to see what OEM builders and add-on developers will do with the new OS.
