Xgrid is the last of the services we'll be looking at tonight, and it's not a new one so we won't spend too much time here. Accessible only via Server Admin, Xgrid is Apple's distributed computing service - basically, it allows many computers to process a single task, thus completing that task exponentially more quickly than any one computer could do alone.

Configuring the service is easy - just select the service in Server Admin, click the Configure Xgrid Service button, elect to create an Xgrid Host, input your Directory Administrator credentials, and you're done.

You can control how clients authenticate to your Xgrid in the Controller tab within the Settings tab. For convenience's sake, I'll just have my clients authenticate with a simple password. By the same token, you can make your server's CPU cycles available to Xgrid in the Agent tab.

Now, to get other computers in on the fun, go to the Sharing System Preference pane, go to Xgrid Sharing, and click Configure. Tell your computer to use a specific controller, and input your server name.

Under Authentication method, make sure what you put here matches the setting you put in on the server, and then check the service's checkbox to start it up.

Now, check to see that everything is working using the Xgrid Admin Server Admin Tool - if you've configured your computers correctly, you should see that a pool of CPUs are available for your use.

Your Xgrid clients can now submit jobs via the command line, and you can use Xgrid Server to start, stop, pause, and dictate the priority of those jobs.

The actual use of Xgrid is a little outside the scope of this review, but sadly it's one of those things that sounds a lot cooler in theory than it is in practice. You can't really use Xgrid to speed up consumer applications from Apple or Adobe - it's best used to help with CPU-intensive calculations, and it's not even ideal for all of those. If you're interested in learning more (and if you're fairly technically literate), I'll point you toward the generally excellent Xgrid wiki and wish you luck.

    Lion's web server IS Apache. LOL.

    I am too much of an elitist fag to succumb to this.
    I just installed my Debian GUI-less server today to replace my o'll ubuntu 10.04 LTS GUI server, got everyhting setup, mysql, apache, php, samba settings, everything gud to go with only 100 megs of ram usage.
    Sure it took much longer to setup, but I am an elitist fag

    Since when is netboot unique to OSX server? Last I checked all *nix variants have had that ability for decades.

    But really, organisations concerned about the sticker price on their server software are not going to go get an apple 'server' for $1k when they can download an iso in 5min and get going are they?
    Not to mention the complete lack of necessary system tools (archiving, compiing especially) without installing macports or something.

    Call it like it is - 1k to manage all those damn pads and phones everyone in the company demands they are able to access the company intranet.

    Time Machine took a big step backwards with Lion Server. In Snow Leopard Server you could allow time machine backups on individual share points. This allows you to partition a disk and set up individual partitions for specific Time Machine backups. I use this to control how much disk space is allocated for a backup. In Lion you get to nominate one share point/partition as the Time Machine backup storage point. Hence any client that backs up to the server uses the same disk space. A real step backwards!

    Another issue is that Server.app rewets .config files when started up so you potentially lose any changes you were forced to make due to the lousy Lion Web service interface.

    I like the idea but still... I wouldn't do it. Apparently they got desperate enough to offer it for 50 bucks. Good job for noticing that no one give a damn since Linux is free and both Linux and Window is established already. I still wouldn't give em my money when they tried to charge in the past an arm and a leg. Who the hell do they think they're going fool? The platform isn't the most active for server development tools. Linux got cloud all up in there and it's actively evolving in many area especially server. Don't even try to bring out that pathetic iCloud. It's not open so nothing is going to back that crap other than Apple, openstack have 50 vendors, big companies, backing that project up compare to iCloud. Apple probably won't ever be able to compete in the server sector but they can leverage their UI and simplicity for their user base, such as the gui sys admin tools described in this articles. They should just stick with consumer base products, trying to compete in the server space market is going to kill em.

    On page 4 of this review, it says ".. our next entries are Accounts and Stats under the Status heading". 'Accounts' should be replaced with 'Alerts'.

    If only this was a review of Windows Server it might be useful. I have never met a fellow tech person/geek who uses any version of Apple Server products. (aside from one customer about 3 years ago who was curious about them).

    It is just the simple facts that apple products are know for a lack of an ability to upgrade, locked to features that Apple thinks you should have and a lack of price efficiency. Windows and Linux offer far superior server products that will run on pretty much any hardware that suits your needs and the only reason I can see there being a point to review this product is due to Apple padding your pockets.

    I know that it seems like Apple (or Steve) has lost faith in the PC as a hub, but I would really love seeing a iTunes Server that multiple users can control using iOS devices playing on Airplay or iOS device itself.

    Some NAS is now getting this features, so I might drop the OS X Server for one of those instead.

    What kind of crazy organization would use a Lion Server? At works, standard is a necessity. A Lion Server is just oddball.

    This seems a bit like OSX Server Lite and Easy rather than a true upgrade to Snow Leopard Server. I wasPthinking of converting an older 'mini to Lion Server (to serve a small business which has MBPs and iMacs, but now I think getting a copy of Snow Leopard Server would be better if I could somehow get it cheap (yet legal).
