Another solution that MAY work, would be to use the free VirtualBox software. I'm not sure if it lets you run multiple vm's at a time, but even if not, you could run just one instance of Linux/somebsd with your Jail support... Sun's VirtualBox allows you to run as many VMs at the same time as your hw can stand. I currently use a MacMini to set up and run multiple RHEL and Solaris instances which I then test together and deploy on real hw. In addition to Sun's xVM VirtualBox there's also Sun's xVM Server for bare hardware virtualization, Sun xVM Ops Center tools for management of multiple VMs and Sun technologies for management of clouds of servers (which may or may not be further virtualized.) These do not necessarily imply using Solaris, but work with a wide array of OSen. However these are all much heavier weight solutions than things like Solaris Zones or even LDOMs. If that's what you want, then use Solaris. It's robust, mature, enterprise class and targeted quite differently than Mac OS X and OS X Server.

Jails duplicate the root or specified directory structure and isolates whatever is running in it from everything else and I can assign resources to it [chroot jails] and BSD Jails are not really analogous to Zones however and your comparisons and interchangabilities of them as being similar is confusing. Unless there's another way to replicate this. I'm going to just use FreeBSD. Well, as pointed out, TMTOWTDI and you could implement what you're trying to do, multiple test web servers that can talk to one another and have their own environments, all on one system, even w/o any chroots, BSD Jails or Zones. And you can implement chroot jails in OS X. But as pointed out, use what you know. Mac OS X was never designed to do everything, nor should it be. This email sent to site_archiver(a)lists.apple.com

On 10.5.7 the data store size is managed by the "aslmanager" utility. See the aslmanager on-line man page for details. You can adjust the time-to-live by editing the / System/Library/LaunchdDaemons/com.apple.aslmanager.plist file. For example, to make the time-to-live 10 days: i am using Mac OS 10.5.7 and i am writing the error data in the asl log file, but after three day my data is automatically flushed from my system its possible.

No need for rumors. From <http://www.apple.com/server/macosx/technology/sixtyfour-bit.html>: "Snow Leopard Server uses 64-bit kernel technology to support breakthrough amounts of RAM — up to a theoretical 16TB. With more RAM, server applications can utilize more physical memory and in turn run faster and more efficiently. In addition, the 64-bit kernel dramatically increases the total number of simultaneous system processes, threads, and network connections that the server can utilize." -- Clark S.

I know Linux binary compat is pretty old (though NetBSD’s the king of binary compat modules), and the state of ZFS on Darwin is anybody’s guess… curious about the others, though.
