One area that the Mac has long lagged behind its PC counterparts is in custom tuning, particularly overclocking. With the Intel Macs this has naturally started to change, though the toolset for overclocking in OS X has been rather barebones. So it's interesting to see that the German division of ZDNet has released the ZDNet Clock tool for OS X.

Using the ZDNet Clock tool Mac Pro and Xserve owners (and those only) can boost the processor, front side bus, and memory frequency resulting in a not insignificant "free" performance gain. It should be noted that overclocking puts a strain on the hardware and should be used with caution as it's certainly possible to damage your Mac. Furthermore, there are several side effects in OS X including distorted system time and problems when waking from sleep (the overclocking is disabled on wake). Nonetheless, for those of you out there lucky enough to have a Mac Pro (or Xserve) and crazy enough to push your hardware to the edge may want to have a look.

The ZDNet Clock tool is a free download from ZDNet (the link is in German, click the Jetzt herunterladen button to start the download) and requires a Mac Pro or Xserve running Leopard.

Amazingly, the commercial hackintosh maker Psystar (whose efforts in building non-Apple machines running OS X we've covered at some length) still hasn't been beat down by Apple Legal and now they're back for more. They are releasing the OpenServ series of rackmount servers which they offer with a variety of OSes including OS X Leopard Server.

There are two models: the 1U OpenServ 1100 (starting $1599) and the 2U OpenServ 2400 (starting $1999) either of which can be purchased with OS X Leopard Server pre-installed for an extra $155 (no clients), $525 (10 clients), or $1025 (unlimited clients). This machines are obviously in direct competition with Apple's Xserve. Frankly, I'm amazed that Psystar is still in business, and they keep pressing their luck. I wonder if this will be enough to push Apple over the edge.

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.

Thanks Russ!

Teaming with Parallels, Media Temple has just announced the start of private-beta period for its latest (mt) Labs offering, the (xv) Xserve-Virtual -- which they are dubbing "the world's first VPS Leopard Server." Although virtual servers running Linux or Windows are pretty standard hosting options, this is one of the first Mac hosting opportunities I have seen period (outside of a co-lo), virtualized or not.

Now that Apple has sanctioned the virtualization of OS X Leopard Sever on Apple hardware, both Parallels and VMWare have announced plans to integrate Leopard Server virtualization into their product lines. While VMWare is integrating Leopard Server in its upcoming version of Fusion, Parallels is taking a decidedly more enterprise approach and working Leopard Server virtualization into its Parallels Server product. Parallels Server uses Parallels' bare-metal hypervisor architecture and as such, each virtual machine runs its own kernel and operating system.

Media Temple, which already partners with Parallels in its (dv) and (dpv) Nitro products, is going to be the first official hosting launch partner for Parallels Server for Mac, offering Leopard VPS hosting on Xserve hardware. The Xserves used by (mt) are running 2 x 2.8 Ghz Quad-Core Intel Xeon 5400s with 32GB 800MHz DDR2 RAM and 3x300GB 15,000-rpm SAS with 16MB disk cache drives on a Xserve RAID Card. In the private beta (apply here), the Xserves will be split into 8 virtual machines, with each VM guaranteed 2 GB of RAM and two cores of CPU resources. The advantage of using a virtual machine as opposed to a physical Xserve, aside from cost, is that hardware maintainance is taken care of by the host. Plus, if something goes completely haywire, the virtual machine can just be reinstalled to its starting point.

The (xv) can be used to host websites, run iChat and iCal server, use Podcast Producer and for anything else a regular Xserve running on a LAN can do. Anything you can install on a regular Mac, you can install on the (xv), and you can control the (xv) using both Screen Sharing and Remote Desktop. Media Temple is still working on the scalability plans for the (xv) but are planning on offering a scale-on-demand package similar to its (dv) product.

Although pricing is currently undetermined, Media Temple will be using the beta testing to find out which configurations are most efficient to help set the ultimate price.

If you have experience running a Mac server, you can apply for the (xv) beta here. It's really exciting to see OS X virtualization, both for enterprise and for home/small business use take off. I can't wait to see the final product!

Thanks Jen and Jorge!

Apple just released an update for the Xserve. This EFI firmware update helps "improve the stability of Xserve computers," so if your Xserver has had stability issues, maybe this is just the update you've been praying for.

If you use Xsan, then you might want to take note of the new update that Apple dropped yesterday. Apple updated Xsan Admin, Xsan Filesystem and the Xsan Uninstaller to version 2.1. According to the update note, the Xsan Filesystem update fixes:

• Metadata controller reliability
• Using and validating file system Access Control Lists
• Upgrading from Xsan 1.4

The Xsan Admin update provides fixes for:

• Using SAN Setup Assistant to configure volumes, LUNs and affinities
• Changing a computer between client and metadata controller roles
• Listing computers connected to the SAN
• Visually displaying when LUNs have been truncated

You can download these updates by opening Software Update on the Mac running Xsan or by downloading the installer packages from Apple's Support Downloads website. For detailed information about this Xsan update, refer to the support note on Xsan 2.1.

Tuesday's launch of Xsan 2 coincided with the discontinuation of Apple's Xserve RAID Enterprise storage system. For shopper's at the Apple Store for Education, it appears that the Xserve in general has been completely removed as well. Although refurbished Xserve servers still come up under a search (as do Xserve parts and accessories), the product page for Xserve is conspicuously missing.

Take a look at these screen shots, one is from the regular Apple Store, the other is from Apple Store for Education:

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.

Well, as Nik posted a bit earlier this morning, the Apple Store is indeed down worldwide. As commenters in that post noted, Apple has updated the Mac Pro line before major trade shows before, and as commenter John pointed out, Apple has just updated the front page of Apple.com announcing upgrades to the Mac Pro and Xserve line. I think it's a pretty safe bet that these machines will be available as soon as the Apple Store comes back online.

So what are the specs? For the Mac Pro the machines are now 8-core standard (!) running up to 3.2 Ghz each (and this is on the new 45 nanometer Quad-Core Xeon). "Fastest Mac ever" is a phrase bandied around a lot -- but in this case, it's absolutely true.

From the press release, the basic configuration ($2799 US) includes:

• two 2.8 GHz Quad-Core Intel Xeon processors with dual-independent 1600 MHz front side buses;
• 2GB of 800 MHz DDR2 ECC fully-buffered DIMM memory, expandable up to 32GB;
• ATI Radeon HD 2600 XT with 256MB of GDDR3 memory;
• 320GB Serial ATA 3Gb/s hard drive running at 7200 rpm;
• 16x SuperDrive™ with double-layer support (DVD±R DL/DVD±RW/CD-RW);
• two PCI Express 2.0 slots and two PCI Express slots;
• Bluetooth 2.0+EDR; and
• ships with Apple Keyboard and Mighty Mouse.

Full CTO options are detailed in the press release linked above.

As for the Xserve, it now includes built-in accelerated graphics to drive up to a 23" Cinema Display and front facing USB 2.0 ports. It is also taking advantage of the new Intel 45 nanometer core technology.

The basic configuration ($2999 US) includes:

• a single 64-bit 2.8 GHz Quad-Core Xeon processor with 12MB of L2 cache and a 1600 Mhz front side bus;
• 2GB of 800 MHz DDR2 ECC FB-DIMM RAM, expandable up to 32GB;
• a single 80GB SATA Apple Drive Module;
• dual Gigabit Ethernet on-board;
• internal graphics;
• two FireWire® 800 and three USB 2.0 ports; and
• an unlimited client license for Mac OS X Server version 10.5 Leopard.

The unlimited client license for Leopard OS X Server is pretty fantastic, as are the power and cooling specs. Full configuration details can be found in the press release here.

Apple released Xserve Lights-Out Management Firmware Update 1.1 on Thursday. It's for Intel-based Xserves only, and will update your firmware to version 1.2.8. The Xserve I manage at work is a G5, so no update for me. Here's what I'm missing, according to Apple:

"This update includes changes to the Lights-Out Management environment of the Intel-based Xserve. It addresses the intermittent issue that causes the LOM port to be unresponsive. This update is strongly recommended for all Intel-based Xserve systems."

You can read the Knowledge Base article here.

Let me ask you something: do you like fast storage? Redundant, fast storage? Lots and lots of gigabytes of fast, redundant storage? Sure you do, buddy -- but what's with the software RAID on your Mac Pro or your Intel-based XServe? That's so last week, now that Apple is shipping the RAID cards for Mac Pro and XServe; you can now do hardware RAID 0, 1, 5, or (Mac Pro only) 0+1 arrays of SATA drives, or superfast SAS drives on the XServe, for the precise mix of speed and reliability that you're craving.

Formerly only available as build-to-order options but now shipping as add-in parts for $999 each, the cards come with a raft of requirements. First, they're only for the machines mentioned above; G5 XServes are out of luck. Second, you can't mix and match drive types on the XServe, it's all SAS or all SATA please. Third, a minor point, barely worth mentioning really, but both these cards are listed as requiring some sort of OS update. Yes, on the heels of this morning's announcement of the MacBook revisions, we now have a total of three pieces of Apple hardware that demand Leopard to work at all.

Update: Clarified that the cards were previously available as BTO parts. Note that even though the specifications say Leopard-only for these cards, existing RAID cards (and possibly these as well, for anyone brave enough to spend a grand to test them) continue to work with Tiger.

Big-iron system admins with a Mac streak (there's more of them than you'd think) would dearly love to see a fully virtualizable version of Mac OS X Server, one that could be slotted into a VMware infrastructure on third-party hardware, and run alongside other server OSes like Windows Server, Linux and Solaris, sharing hardware resources and reducing administrative costs. Shame that it won't happen: Apple's licensing doesn't permit running 10.x Server on anything other than Apple gear. There is some change in the air, though, as a careful reading of the new license agreement for Server 10.5 reveals -- virtualization of OS X Server on OS X Server may be coming sooner rather than later.

A post on the Macenterprise mailing list and an article at TidBITS take note of this licensing change, which now would seem to explicitly permit the use of multiple instances of Mac OS X Server on a single Apple machine. With this green light, applications like the in-early-beta Parallels Server and the unannounced but surely-in-progress VMware equivalent could provide multiple instances of OS X Server along with Linux or Windows VMs, all on the same box. Depending on how your network services are set up, this could be a big help in selling X Server into your organization.

We'll keep an eye on both Parallels and VMware for future announcements in server virtualization. Exciting times!

With all the patching and fixing to make ready for Leopard, it's no surprise to see some of Apple's infrastructure tools getting updates this week. Moments ago it was ARD 3.2, and now it's Xsan Admin Update & Filesystem Update 1.4.2! The new software for storage-area networking "addresses numerous issues related to overall reliability, usability and compatibility." Dee-lightful!

Specific patches include FC LUN mounting on Leopard, failover improvements, reduced chance of file system metadata corruption (always good), and support for hosting Xsan volumes on Intel-based metadata controllers. Complete list of features under read more or over at Apple's knowledge base. It's recommended that you peruse the Xsan Migration Guide (PDF) before upgrading your clients; note that the metadata controllers must be running the same (or higher) version of XSan as all your clients, so patch with caution.

With the release of all the Leopard Server specs, eagle-eyed reader Tony notes that Apple's Server Administration information page shows a screenshot of an intriguing configuration: a 2x 2.7Ghz Dual-Core Intel Xeon-based XServe. No such machine with that processor config is currently available from Apple.

Factor in that Intel doesn't actually ship a 2.7Ghz Xeon dual-core chip at the moment, and it seems that Apple and Intel may well be plotting a new build of the XServe on a new CPU for eager enterprise customers, just in time for Leopard Server.

I've been toying around with the idea of building a full Mac media server for my family, but this project by James Hodge puts any ideas I had to shame. His Ultimate iTunes Media Server is built around a PowerMac G4 with an Xserve RAID for storage. Content comes by way of over-the-air HDTV to Elgato's EyeTV, ripped DVDs, and iTunes Store purchases and is delivered to three Intel Mac mini clients over a gigabit Ethernet wired network. His total equipment cost is over $10,000. I think using the $5k Xserve RAID for storage really takes this one over the top. Anybody looking for some ideas for an iTunes server should check out the complete description of James' efforts.
