Review - Mac OS X Server 10.3, Part 1
Sure, I can read. I can go to the Mac OS X Server web site and read all the documentation for things related to "standards-based management," "share printers and files," "n-tier" solutions. Yawn. I know all about this stuff, and I know I can do it already. If I am paying good money for this, it better have value I can't already get for free.
First Things First
Essentially, Mac OS X Server is the same thing as Mac OS X (a.k.a. Client). It's the same core OS, it has the same versioning (10.3.2 as of this writing), it runs the same programs. But Server comes with programs and tools and configurations geared toward being a server, rather than a user's workstation.
Server comes in two flavors: a 10-client version for $500, and an unlimited client version for $1000. The only difference between the two is that the 10-client version limits file and windows sharing to 10 simultaneous clients. You can have any number of users, but only 10 can connect to those services at the same time.
With that money, you also get 90 days of "up-and-running" support covering the software that ships with Server. So if you've read the frelling manual and still can't figure out why the firewall doesn't seem to be working, you can get some help. After 90 days, you can still get help -- including more advanced topics -- but it will cost you from $6,000 to $50,000.
Hardware
The Xserve, Apple's rack-mountable computer, comes with the unlimited client version of Server preinstalled; and really, Server is built with Xserve in mind. Server Monitor, included with Server, displays uptime, temperature, drives, power, network usage, fans, and security of Xserve boxes.
You can configure Xserve boxes automatically with Panther Server preinstalled. Design your configuration on one machine, set up an LDAP server and put it in the DHCP server settings, and add your configuration file to the LDAP server. Turn on the other servers for the first time, and each one will find the DHCP server, find the LDAP server, find the configuration file, and configure itself automatically. You can also put the configuration file on a USB key or somesuch, and the machines will configure themselves that way, too.
My test box is a dual G4/1.25 GHz Power Mac; it performs with nary a hiccup. If I had a large network or many users, I can imagine wanting more power: with a Power Mac or Xserve G5, I'd be able to take advantage of an OS that is optimized for the 64-bit CPU. For me, however, this would result in a depressingly, perpetually, low CPU load.
Initial Security Considerations
Out of the box, assuming no one has set up a rogue DHCP server on your network, Mac OS X Server is mostly secure: only SSH is on by default. As other services are turned on, more security concerns are created, because new security holes may be opened.
For the most part, the default configurations of the various services are secure, but that largely depends on your specific environment. Mac OS X Server is excellent at making advanced server configuration easier, but this ease of use comes with a price: you may be opening yourself up to attack. Mac users are often not used to the idea of making themselves vulnerable just by clicking checkboxes.
This may look like a Mac, and may be easy to use, but it is no substitute for having a real live sysadmin on hand to -- at the very least -- audit the security of the system. It'd be nice if Server included audit tools; I envision UI elements that warn you when you have conflicts, or when you've opened up a hole, or when you've violated predefined security policies. On the other hand, it would be more reliable to have a third-party system to do the audit, on basic principle. But that's so un-Mac-like.
Open
Tom Goguen, Director of Marketing for Mac OS X Server, says that Apple is 100% into using open standards and open source in the core operating system.
Mac OS X Server has always been largely based on open standards, but the Panther incarnation has gone even further. Gone are Apple's proprietary mail systems; they are replaced by postfix, mailman, and cyrus. Mostly gone is NetInfo; it is replaced by LDAP. Rendezvous, also an open system that others can plug into, is a bigger part of Server now: FTP, LPR, and web services are all announced via Rendezvous.
Of course, as always, Server -- just like Client -- is based on FreeBSD (now version 4.8, with some of 5.0 stirred in), and most of the Apple core OS itself is under the Apple Public Source License.
A Case for Case
New to Panther is case sensitivity in HFS+. For many years, Mac OS has used the HFS as its file system, which treated "Foo" and "foo" as the same file. Some years ago, HFS+ was introduced to overcome many of the limitations of HFS, but case sensitivity -- seen more as a usability feature than a limitation -- remained.
But in Unix, this certainly is a limitation for many people. "Makefile" vs. "makefile" and "head" vs. "HEAD" have caused many a headache for Mac OS X/Unix users. But now case sensitivity is a formatting option.
Because case insensitivity is still seen as a usability feature, this feature is not available by default on Client, although you could always connect your drive to a Server to format it. It is also possible, in theory, to format a drive with case sensitivity in Client using various tricks.
Setting it Up
My server is connected to my home network via a 100BaseT switch, to which is also connected a cable modem and an AirPort Extreme base station. My PowerBook G4/867 connects to the network via AirPort or the switch. My wife has an iBook G3/600, and I've got a PowerBook G3/400 in my stereo closet for playing MP3s. The PowerBook doesn't have internal AirPort, and instead is connected to another switch and another Extreme base station, configured to do WDS. I've also got the PS2 connected in there. Everything is running Panther Client (except for the PS2, last I checked).
Looking at the various services offered by Server, I can already see many things I want to set up: file sharing (Apple Filing Protocol, or AFP), DHCP for guests, DNS, FTP, SMTP, printing, and web. I have most of those already set up now, but I wouldn't mind if they were easier to configure and manage.
After surveying my situation, I installed Panther Server and took a look around.
The first thing I wanted to see was what my configuration options were. And lo, there in my Dock were not the expected iMovie, iTunes, iPhoto, and the like, but icons that a mouseover revealed to be representative of programs like Workgroup Manager, the aforementioned Server Monitor, and Server Admin.
Workgroup Manager uses a lot of terminology that is completely lost on me, and I am not managing any users, really. My wife doesn't need the file server -- we can exchange files via iChat, or I can copy them to her machine via scp -- and she keeps all her own files on her machine. We won't be using any print quotas. I do use Workgroup Manager to create some basic user accounts for friends, but I don't need any features more advanced than what is in Client.
Server Admin is what I want to sink my greedy little digits into. I opened it up, clicked the "add new server" button, typed in my server name ("Sweeney.local") and password, and started playing.
As I started looking around, I remembered that there was an extra CD in the distribution called Admin Tools. It allows you to install these tools on any Client machine, so you can manage the Server remotely. I want to go hang out in my La-Z-Boy while I configure my server, so I installed the tools on my PowerBook. Nifty.
Server Admin lists each machine and the services available to it, with an icon next to each describing its status. If you select a machine's name, you see several tabs: Overview, Logs, System, Graphs, Update, and Settings. Overview reports the system version, names, and dates. Under Logs, you can view the system log, watchdog log, etc. System reports what network interfaces and volumes are available. Graphs displays CPU and network use in pretty pictures. Update runs Software Update. Settings controls the system names, the date and time and timezone.
This is basic stuff, and each service is laid out in similar fashion. All of them have at least two tabs: Overview and Settings. Most also have a Logs tab. Some have other tabs like Connections, Graphs, Clients, Activity, Accounts, Queues, and Jobs.
The available services are AFP, Application Server, DHCP, DNS, Firewall, FTP, Mail, NAT, NetBoot, NFS, Open Directory, Print, QuickTime Streaming, VPN, Web, and Windows. Somewhat conspicuous in its absence, to me, is MySQL, which is included in Server, but doesn't have an interface in Server Admin.
Server Admin does have its problems. It will crash on occasion, but I see no evidence of my settings being corrupted, or any other lasting ill effects. Some of the lists are not sortable, though they appear to be: for example, the DNS zone listings are not sortable, even though clicking on the column headers indicate otherwise.
Also, it can be slow to update. This is understandable, but annoying. Logs don't refresh immediately, and when you hit reload, the wrong log is selected, instead of the current log being refreshed. When restarting services or viewing logs, I will sometimes use the command line tools, as they are more efficient; it would be nice if Server Admin would display the path to the log you are looking at, so you can easily find and tail it in a shell.
Sharing
Some of these services are available in a minimal form in Client, in Sharing under System Preferences: file sharing, Windows sharing, web, FTP, and printing. In Server, the Sharing preferences are still there, but contain only three items: Remote Login, Apple Remote Desktop, and Remote Apple Events. Remote Login is simple: it allows users to connect with ssh/scp, and can be turned on or off. The other two require, perhaps, a bit more explanation.
Apple Remote Desktop is a way for an admin to control client computers. Previously, the client was distributed only as part of the software package of the same name, but now the client is included with Panther. It is, of course, off by default, and once turned on, each machine must define what users have access to what resources (this can be done via the command line, too). I most commonly use ARD for controlling and viewing the screen of another computer, installing packages, and copying files.
Remote Apple Events has been in Mac OS for many years, since back in version 7-dot-something. It allows controlling "scriptable" Mac applications -- such as with AppleScript -- over the network. It used to run over AppleTalk, but now runs over plain old TCP/IP. Not many people make use of remote Apple events in my experience, but I use them often; for example, I have a Perl script that queries iTunes on a remote box, and sets the current track in iChat.
Windows
I don't use Windows, and therefore can't really test the new Windows integration in Panther Server. But from what I can tell, Apple has added quite a few improvements. Samba has been updated to version 3, and the lists of Unix and Windows users can be united via Directory Services. But I confess to a crippling ignorance and apathy about this small corner of the computing world. Sorry.
To Be Continued
Tomorrow, I'll get into the details of setting up the services I use on my network.
Yawn. I know all about this stuff, and I know I can do it already. If I am paying good money for this, it better have value I can't already get for free. You may be able to do it- but to those who cannot a simpl GUI on top makes a world of difference. Different strokes for different folks- don't buy it.
Tomorrow, I'll get into the details of setting up the services I use on my network.
iCan't wait for more of this.
Actually that would mean that Apple is charging per connection, not per user. So if you have 100 users a 10-user license would work as long as your users can be limited to 10 at a time. So lo-and-behold they didn't succumb to what you're asserting.
That's right.. the Mac has been dying for 20 years now. Another 10 should just about wrap it up..
Trolling is a art,
This has always been their pricing scheme. It's assumed that if you need more than 10 concurrent connections, the $500 difference is negligible, and you just go for the $1000 unlimited client version. Which is still _much_ cheaper than MS server licensing. Think of the $500 as a cheap version for small businesses or students.
Where did you get this "After 90 days, you can still get help -- including more advanced topics -- but it will cost you from $6,000 to $50,000." quote? Link? Facts?
It's either on the beat or off the beat, it's that easy.

The main reason Apple developed the XServe is because their original server, the iRack, was inadvertenly taken over by the US military due to a typo.
Please stop saying that MacOS X unix tools is based upon FreeBSD.
:
/usr/bin/* /bin/* /sbin/* /usr/sbin/* 2>/dev/null | fgrep OpenBSD | wc -l /usr/bin/* /bin/* /sbin/* /usr/sbin/* 2>/dev/null | fgrep FreeBSD | wc -l /usr/bin/* /bin/* /sbin/* /usr/sbin/* 2>/dev/null | fgrep NetBSD | wc -l
:
Apple actually took parts of NetBSD, FreeBSD and OpenBSD.
Most tools actually come from OpenBSD.
If you got MacOS X and if you need a proof, just try
ident

ident
Here's what I get on Darwin 7.2.0 (Panther, everything up to date)
OpenBSD : 303
FreeBSD : 258
NetBSD : 143
The rest is mostly GNU tools.

I think Apple missed the boat not supporting these Macs with OS X. They make great little OS X workhorses.
It's either on the beat or off the beat, it's that easy.

So is there a client limit on regular OS X? (Client)
How many clients can connect to OS X Client? That would be interesting to know. Granted, the server version comes with tools, but what tools are really there that aren't available for free somewhere?

While you can easily do everything that Panther Server does on your linux box, what Panther excels in is integration. Specifically the binding together of OpenLDAP, Samba, Apache, Postfix, IMAP, POP, and CUPS with the OpenDirectory password server. OpenDirectory's password server is essentially a SASL password store that they've hacked all the programs mentioned to interact directly with it for all authentication. Think of it similarly to what pam does for linux. The nice thing about OpenDirectory is that a password change from any of these mechanisms (say via samba) then all of the password hashes in the database are automatically synced (even kerberos is synced). This makes for very slick administration of users all from one central console. In the past on Linux, it was not uncommon to have to hack together some scripts to syncronize ldap, samba, and kerberos authentication stores. Even in the best case right now, samba password hashes have to be kept in the ldap database along with either an md5 hash for unix logins, or a pointer to kerberos. With OpenDirectory, there are no passwords stored in ldap itself. Instead an Apple Password field points to the password database which can provide md5 challenges and responses, samba challenges, and general password verification.
Essentially OpenDirectory brings all the technologies together that we already use and make them into a service that competes very well with Active Directory or NDS.
Another bonus is that since OpenDirectory (all its parts including the SASL password database and patches to cups, samba, etc) is open source, we could build a complete OpenDirectory-compatible system on Linux. I plan to do this over the next year or so. Most likely there will have to be a pam module created, and some patches made to OpenLDAP, Samba, etc. But it's a very exciting example of how to put open source projects together and have them work really well.
You know, a lot of friends and colleagues have been laughing at me when I tell them that Mac is the new force to be reckoned with. I've been watching them for a little while now and ever since they integrated FreeBSD into their OS, they've taken on a new direction which seems a lot more proffitable.
Don't get me wrong, I still have my two Linux and two OpenBSD boxes at home along with the obligatory windows boxes for the wife, daughter and gaming.. but you know what? I'd love to get my hands on one of them OS X boxes..
If you don't think I'm right.. that's your opinion.. but I know if I had OS X experience, I might be able to get a job Here!

No matter how subtle the wizard, a knife in the shoulder blades will seriously cramp his style.
...I really do want to know why I should use this in a Win2K environment. My boss wouldn't care what I get as long as it does the job. What I want to know is: Can this server provide me with tools to form a good bridge between Windows, Apple, and Linux clients?
SAMBA 3, from what I read is GREAT, but it in no way yet compares to the ease of use of MS's Active Directory tools (at least in configuring Windows clients).
"...Well, there's egg and bacon; egg sausage and bacon; egg and spam; egg bacon and spam; egg bacon sausage and spam..."
To me, Workgroup Manager is the reason to buy OS X Server (assuming you are running a Mac OS X network with multiple users and OS X clients). It is a nice, zero effort way to manage multiple users and client computers - controlling who can use which client computers and which files/folders will follow them around from computer to computer.
there is a two tier Mac OS X server licenseing structure...
little guy - 10 clients - $500
everyone above that - limited only by performance - $1000
the drop-dead MSCE-simple admin tools of Mac OS X Server more than justify the $1000 difference in price vs Linux if you're going to be running these things by yourself, and you have a real job on top of it.
guns kill people like spoons make Rosie O'Donnell fat.
Wow, even when there's no article to click on to read, you don't even read the review - just the headline and the "Reply" button. Try to read it, and understand that the Apple hardware is super reliable, supported, and runs an easy to use, high performance, standards-based OS with open-source apps. Then consider that many people have Mac technique experience, from GUI to other skills, and those skills can be used to get the power of a commercial unix server: MacOSX Server.

You're missing the killer server features.
You know how Kerberos can be a real pain to set up and manage? Well with Panther Server, if you've set up a box as an Open Directory master, it automatically integrates itself as a KDC.
Any boxes which log into that OD/LDAP directory automatically retrieve the relevant Kerberos information from the LDAP store, no extra configuration required.
The AFP server, the SMB server, the POP/IMAP/SMTP servers are all Keberized, as is the ssh daemon, and the loginwindow of any client machines.
It's probably worth discussing the fact that Apple have finally gotten their shit together with regards to command line administration, as in that everything you can do with the GUI tools you now have *simple* command line equivalents.
ie, no more screwing around with NetInfo and inserting properties by hand to construct mounts/users, you now have proper tools.
Apple finally did the smart thing and followed what most OSXS admins have been doing for a few years, they've dropped their proprietary AppleMailServer in favour of postfix+cyrus.
They've pretty much dropped NetInfo for network directories, it's now just restricted to a local store, and LDAP publishes this information by default. You can still run a NetInfo directory, and indeed I've got boxes logging into both my old NetInfo directory and my new LDAP directory so that I can do user migration more easily.
There are a wealth of features that weren't even touched upon by this review, it's just kind of lame to read a home user's review of a server product.
i don't read slashdot anymore.
I have been a Linux user for about 10 years (when I first got Slackware over a 1200 baud modem) and until recently I was using a super-cheap Linux box to run Java server side stuff for my little NLP software business.
I switched over to using an old G4 Mac for running web services about 4 months ago. It is a little too early to tell, but I seem to be spending less time taking care of the G4 server (approxametely 1 hour a month - and I think that I used to spend 2 or 3 hours a month messing with my Linux server).
Anyway, a life for old Macs :-)

Most source files that, when compiled, have RCS IDs in the resulting object file, and that are used to build tools, came from OpenBSD.
Try running a script such as
and look at the output. Many tools have no RCS IDs in the binary. Some of them have multiple RCS IDs in them, as more than one source file for a tool in that set has an RCS ID in it that shows up in the object file.
If we prune that output to leave, for each tool, only one line for each OS for each tool, we get 85 lines for NetBSD, 75 lines for FreeBSD, and 19 lines for OpenBSD - OpenBSD is overrepresented in your results because, for example, the OpenSSH stuff came from OpenBSD, with each tool having multiple source files, and most if not all of those files put the RCS ID into the binary.
NetBSD is slightly overrepresented by the counts I gave, as Panther's yacc came from NetBSD, and its skeleton parser puts an RCS ID into the object file; if we remove those 7 lines, we get 78 for NetBSD.
Of course, there are a lot of commands that don't have any RCS information at all. 171 commands do, but there are a total of 928 commands. This means that your counts and my counts don't necessarily give any believable information about the number of tools that came from FreeBSD, NetBSD, or OpenBSD, unless all the tools without RCS IDs came from elsewhere (GNU, Apple, etc.).
Hi, I have pac man fever so I bought the most expensive box at the store - OSX Server.
I put it on my computer, and then put a laptop on top of my stereo.
And then I dont really use it for managing stuff or sharing files theres only me and my cat in the house, also I dont know about technical stuff like kerbones because I'm not much of a computer guy I just know the most expensive stuff HAS to be the best.
So all in all I give Mac OSX Server a 10 out of 10 it is very cool and has wonderful animated icons, and not too many buttons on the mouse to confuse me.
Stay tuned for part 2 of my review, where I plan to put my iPod next to it and take pictures!
I don't need no instructions to know how to rock!!!!

Does this mean that, on macs, you can
1. Script GUI apps
2. Script them over the network
? That gives the traditional unices a run for their money, I should think...

Think of the $500 as a cheap version for small businesses or students.
For students, it's even cheaper. The educational pricing is $249 for the 10-user version and $499 for the unlimited version.
People who want 1> reliable, long lived hardware 2> relatively easy, familiar operating environment with standard apps 3> affordable support from an experienced, user-friendly service organization that actually develops the tech they're supporting. Total Cost of Ownership studies are probably available from Apple, and I'd expect they're compelling, especially for the installed base of Mac shops. You'd be surprised how much easier selling a server platform to IT can be, when there's a marketing team with decades of experience behind them, a brand name before them, and solid business cases for their technology holding it all together.

make install -not war
When I had both machines in place I ran into an issue where I had to rebuild the main one, so I transferred the data to the secondary server and planned to swap them. I changed their settings and IP addresses ... and all of the user accounts on the primary file server disappeared.
This was odd.
I Googled for it and came up with the answer: if you set up a password server on 10.2 Server you can't change the machine's IP address. This has to do with how Apple built the LDAP system that manages passwords, so it's a requirement if you want Windows file sharing (Samba in disguise) enabled. Which I did.
I called Apple tech support and they confirmed it: if I wanted to do Windows file sharing, I needed to set up a "password server" (LDAP). And if I set up a password server, I couldn't change the IP address of the machine. Ever. If I did, the users and groups would vanish into thin air. I asked if I could back up the user and group databases and then upload them again ... and they said no. Not without stripping the passwords out. So I'd have to have my users reset their passwords.
I was stunned. The inability to back up user account information, complete with passwords, and to change the IP address is ridiculous, and not the mark of a true, flexible server OS. So right now I'm migrating them to PPC Linux with Samba. I know 10.3 Server probably addresses these issues, but Linux is just simpler. Heck, all I have to do with Linux/Samba is replicate the passwd, group, shadow and smbpasswd files between the machines. Instant mirror servers. And it'll just work.
Besides, tar and mt will give me better control over tape backups than Retrospect did. Retrospect was always propting me for tapes of a particular set, and rejecting tapes that were from the wrong set. I don't give a pair of fetid dingo's kidneys about backup sets. On Linux, it's just "See that tape drive? Put the data there, and shut up about it." And it does. And it's good.
End of rant.
Heh. A 9500 only has two drive bays- three if you feel like ripping out the floppy and boring holes in the case with a dremel. When it comes to internal drive capacity, you want a 9600, 8600, or beige G3- all of which have internal tray capacity for five drives (one 3.5, then four in the front that are universal trays with mounts for floppy, zip, hard drive, and CDRom- you can easily drop out the floppy and smack in a hard drive). Alternatively, you can add a few firewire cards and load in several drives, but you're still limited by the system bus. :P
:)
:D
My home fileserver is a beige G3/266 with 256 megs of ram. Two IDE hard drives - a 60 and an 80- UWSCSI for an internal 4g disk, an Adaptec 29{3|4}0 card for the outboard 9g SCA drive that holds the OS, and an Apple rom 10/100 ethernet card. It's running 10.2 Server (10.2.0- I've never bothered to patch it up) and runs out basic file services to my home network. Runs like a champ, minus the initial pains in the arse of getting the OS actually ON. All of the SLOW one experiences in OS X is totally at the graphical userland level, in my experience- which isn't something the server uses. My workstation (also a biege G3, running Panther Client thanks to XPF) is a slug, and it has 128 more ram than the server... but I use it largely for gui stuff, and the OS is (UNFORTUNATELY) on an IDE drive- the big SCSI went into the server.
I could easily do the server on my 9600 with the Sonnet ATA/66 card that's in my 7300, but the ATA card seems to be a bit flaky, and the 9600's already running linux just fine....
Alternatively, I could toss on Server 1.1 without using XPF at all. It's neat to play with if you can find the media, although I personally wouldn't use it for anything other than Apple File Services.
It is less hassle to get 10.2 or 10.3 onto a beige mac, if you don't have much linux experience- but linux has this funny habit of supporting older hardware that OS X screams about.

If you run a Mac network, you can do really cool stuff with Automount points. All my Macs mount a /Network/Application, /Network/Library, and a few other mount points thrown in. The GUI land includes /Network/Library in the search path for stuff, (/System/Library for system installed stuff, /Library for stuff installed by the Admin, ~/Library for stuff installed by you, nice and clean and straightforward).
/Network/Applications (server installed apps with drag-and-drop, really nice) /Network/Library (frameworks for custom Cocoa apps, etc) /Network/Software (software installers, why not, right) ... and the Users share, that unfortunately can't be automounted as /Network/Users
Each AFP mount counts against the license, no biggie... 7 Macs, all permenantly connected, and we had 3 connections left for laptops.
Incorrect. While all my connections, once logged in, go through one AFP connection, the Automount connections are done anonymously. Oh no, 2 AFP connections from machine->server, anonymous automounts, then w/ permissions mounts. It's worse! Each automount creates it's OWN connection.
So we were automounting:
well, I had 4 (at the time) automounts, so the first two machines to boot were fine, but machine 3 was all messed up.
Took forever to diagnose and realize that we needed an unlimited license.
Took a few hours with Apple support to diagnose, and they didn't figure out the problem until I started at Server Admin and had the problem. Users couldn't log in, because starting with machine 3, they couldn't get their home directories.
I REALLY like OS X Server's admin tools. LDAP went from scary and impossible to point-and-click. However, even with Panther Server, MUCH better than Jaguar Server, it has some issues.

Running those same commands on my FreeBSD 4.9 server, I get the results: 60/6769/440
The *BSDs share so much code between each other, and most source files have ident tags from different *BSDs, that Apple could have mostly pulled from FreeBSD and may still produce the numbers you saw.
And if I set up a password server, I couldn't change the IP address of the machine. Ever.
This has been addressed by Apple with a script to change the IP settings everywhere necessary, without breaking any services.
Works like a charm, I had to do it a couple months ago for a client.

An important feature of OS X Server is the Server Administration tools. My own home server, which has the internal 6 meg ATI chipset (see above post in this thread) is a slug when I need to hit the gui. But I don't. Apple has provied Server Admin Tools with OS X Server, and the tools for Jag run very well under Panther client. These gui tools allow me to add users, manage shares, manage printers, quicktime streaming (if in use), configure Apache to an extent, DHCP, Netboot.... basically, everything you DO with a server that you don't do with client. And the tools can be installed on ANY machine running OS X. Load them up, they ask for a server IP or domain name. Enter it in, it asks for your password for the server (admin accounts only, naturally). And BLAM!
:-)
:-) And I've never had problems with hard drives bigger than 8g running OS X on IDE host adapters- I had 10.1 installed on a 60g in a 9500 awhile back, and it was Just Fine. This is due entirely to the controller- the system sees it as a SCSI drive. :D
I have complete remote control of all of my server functions from my workstation, and the ones I can't access via the gui tools can be hit through the command line. With the older Server 1.x, you needed a web browser to manage shares, which was both interesting (the convienience) and annoying (security, you needed to be at ANOTHER MACHINE that WASN'T THE SERVER to do it).
Yeah, you can do hardcore awesome amounts of remote management with linux (I recently recompiled a kernel, formatted a RAID array, installed and set up samba, netatalk, and genrally completely configured a linux server from my desktop through a slew of terminal windows. SO SEXY OMG), but the gui tools for OS X are AWESOME for admins with limited command line fu- I got Jaguar Server up and completely configured just how I wanted it without help, compared to both of my monitors being strewn with google searches and man page entries with my linux configuration process. Some people don't want to do it the hard way, and can't afford the new toys.
As for compatability and stability of G3 boards... I only had stability problems if I diddled with the defaults on the control software. So I didn't. I've run OS X, Linux, and MacOS 9.x on g3 upgraded machines, rock solid, without difficulties.
And concerning the 8 gig limit- that only affects Beige G3s and the original iMacs. And only on IDE drives. My workstation had to be partitioned (80g- 8/2/$), my iMac had to be partitioned (60g, 6/54), and my server didn't (9g SCA). It's an IDE thing, not a SCSI thing, and the old beige machines such as the 9600 are SCSI.
There is no UI in ServerAdmin, but there is a GUI tool for MySQL management on OS X Server called 'MySQL Manager.' It is pretty limited in functionality, but it is there.
Note that all XServes ship with X Server, so the cost of the software is only if you are installing it on other hardware.
The features that make the software nicer than Linux (simple setup, integrated password management, easy to use/set up Kerberos, hand holding phone support, etc.) are aimed at a class of people who typically find that it is well worth the $500 they may have paid.
Those who are happy to spend the sea of time and effort reading the docs on configuring a completely integrated PAM/KDC/OpenLDAP/Samba/Apache setup on their choice of Free OS don't appear to be in that target market. IMHO, you can't really sell much in the way of software to people like that, anyway.
Hyperbole is the worst thing ever.
NetBoot is a function based partially in Open Firmware that allows a client to be booted by a Mac OS X Server machine via ethernet. You connect the client to the ether and hold "n" while after you hit the power key. (You can also hold option to get a list of all bootable partitions/devices connected to the machine, which will include valid NetBoot servers.)
/really/ easy to set up and maintain on the server end.
We use it at work to image machines for a school system. There are a couple of dozen schools, each with its own image, and when we need to reimage a machine, we hook said machine to the Xserve's switch and bang, the machine boots and a program called NetRestore (third-party) is run to reimage the machine. (You don't need NetRestore, but it makes our day easier.)
NetBooting is really fast and really elegant, and on top of that, it's
I 3 NetBoot.
