PLUGgers! Here's a comparison of AIX and Linux. FYI
Comparing Linux to AIX
Linux Strategy
Linux is the ultimate in open systems operating environments. It is
acquirable at no cost as a download over the Internet and very
inexpensively as a kit. Both the kernel and extensions are available as
source code and can be improved by anyone willing to make his/her work
publicly available.
Several companies have grown up around the Linux phenomenon--the most
prominent being Red Hat and Caldera--which provide service and support
to Linux users and additional capabilities for the Linux operating
system. Although Linux is supported on most processor architectures,
most of the attention has been focused on Linux for Intel platforms.
IBM has partnerships with Caldera, Red Hat, SuSE, and TurboLinux for
Linux distribution. IBM currently offers Linux with the 43P-150, B50,
and F50 servers. IBM plans to deliver a Linux application execution
environment that will allow Linux applications to run on AIX 4.3.3 and
Monterey in the second half of this year.
IBM views Linux as a common application platform for the Internet. IBM
has delivered the critical elements of its Application Framework for
e-business on Linux including DB2, Websphere Application Servers,
Domino, MQSeries, Developer Kit for Java, Tivoli system management
tools, and VisualAge for Java.
Linux has shown itself to be competitive with commercial operating
systems for a limited number of applications. Linux has made
significant inroads in the following markets:
Low end or midrange Web serving
E-mail routing
Network printing and file serving
Technical computing
Linux is not competitive with other UNIX operating systems or Windows NT in
the enterprise arena.
The widespread adoption of Linux in university and research environments
is bringing a wealth of Linux and UNIX trained professionals into the
market.

IBM Score Card
|----+--------------------------------+--------|
| 1 |Scalability | ++ |

| 2 |Networking Protocols | + |
|----+--------------------------------+--------|
| 3 |High Availability | ++ |
|----+--------------------------------+--------|

|----+--------------------------------+--------|
Legend: + = IBM advantage, ++ = Significant IBM advantage
1. Linux lags both conventional UNIX systems and Windows NT on several
scalability criteria:
maximum physical memory
64 bit large file support
SMP scalability
commercial performance clustering
2. Linux trails AIX in its networking protocols. AIX has the strongest set
of IP features among the major vendors including support for IPv6 and IPSec
and a secure VPN offering. IBM offers the strongest package of electronic
commerce options including a proprietary set of e-commerce solutions with
its Net.Commerce product and Payment Suite. IBM has delivered critical
elements of its Application Framework for e-business on Linux.
3. IBM?s HACMP sets the standard for high availability for UNIX systems,
supporting up to 32 nodes in a cluster and the ability of applications to
monitor the cluster environment for events that are critical to their
well-being. The major storage management vendors, Legato and Veritas have
announced their generic clustering products are or soon will be available
on Linux. A new player, SteelEye, has ported NCR?s LifeKeeper to Linux.
While the future bodes well, these are version 1 products that are still
immature.
4. AIX 4.3.2 sets the standards for system management capabilities with its
remote-access Java-based system management tool and near plug-and-play
support for hardware configuration management. Linux lacks features such
as Workload Manager and QoS (quality of service) found in AIX 4.3.3 that
allow administrators to set and implement policies for resource
utilization.
