Parallels Server for Mac available now

In October, when Apple introduced a change in policy allowing Leopard Server to run in a virtual environment on Apple hardware, Mac IT geeks everywhere looked forward to the day that they could run Windows Server, Linux and OS X Server all off their pretty Xserves. That day is today, because Parallels Server for Mac is now out of beta!

According to Parallels, this is the "...first server virtualization software to run on Intel-based Xserves...and to power VMs running on the Mac OS X platform." Similar the the Parallels Desktop product, Parallels Server lets you run virtual instances of different operating systems on top of OS X Leopard Server, including Leopard Server. The next beta of VMWare's Fusion, which like Parallels Desktop is a consumer product, will support Leopard virtualization as well, but Parallels Server is a little different and aimed at a different market.

The difference is that the hypervisor used in Parallels Server is hardware optimized and takes advantage of Intel's VT-x acceleration (which new XServe and Mac Pros have) to provide a more robust experience with better allocation of resources and memory. This makes the experience much more akin to running a completely separate machine, as opposed to running one OS on top of another.

Yesterday, we reported on Media Temple's new (xv) project, which is the first official service that will be run on Xserves running Parallels Server for Mac. The (xv) will be running multiple VMs of Leopard Server, but Parallels Server can also support Linux (Debian, SUSE, Red Hat and Ubuntu), Windows (Server 2008, Vista, XP and Server 2003 and Windows 2000) and FreeBSD 6 and 7 as guest OSes. So if you run your website off of CentOS (which is based off of Red Hat Enterprise) but your company network runs off of Leopard Server, you can do both off of one Xserve.

Make no mistake, this is an enterprise product, and as such, it is pricey. Parallels Server for Mac is $1248.75 for the software and one-year of support and maintenance and that's before you add in the cost of any software licenses you might need, but that's still a lot less expensive than another Xserve.

For enterprise users who are interested in virtualization, definitely check out the free trial.

Apple launches Xsan 2

In addition to dropping the price on the Shuffle (and introducing the 2 GB version), today's big Apple store update appears to be the launch of Xsan 2. Xsan is Apple's Storage Area Network (SAN) file system, and while this update isn't as sexy as a new consumer laptop update, it's still pretty cool.

Xsan 2 has been received some significant updates; not only is it now fully compatible with both OS X Leopard and OS X Server Leopard (in fact, Leopard is required to run Xsan 2), it is also now qualified to work with third-party RAID storage.

Even more exciting (at least for anyone who has been holding out for some kind of Final Cut server solution) is the introduction of what Apple is calling, MultiSAN. MultiSAN, according to Apple, "[allows] users on a single workstation to access multiple SANs at the same time." Using the video editing example, this means that a segment producer could access both a broadcast and b-roll volume from the same machine. Additionally, the administration tools have been redesigned. Administrators can now create pre-set volume workload settings for different file types/purposes.

To be clear, this is an enterprise product. Xsan 2 is available now for $999 US. Xsan 2 is qualified to work with the Xserve, Mac® Pro and Apple Fibre Channel PCI-X cards, as well as qualified Fibre Channel switches and RAID storage hardware from third-party vendors.

Update: As Tim in the comments pointed out, it appears that Apple's Xserve RAID device is no more. The page now re-directs here, with a link to Promise's RAID solution.
