There are cards that have drivers for Solaris but not Linux or FreeBSD. There are tools and functionality in Solaris that I couldnt find in the others and had to use Solaris for some things.. such as SNAT between an ethernet and tokenring card. All linux kernels crashed after a while of doing this and so did FreeBSD with its lone Olicom driver support. Solaris held on. In other places, FreeBSDs performance just beat Solaris out of the water (no Java thrashing the harddisk like its Baghdad).
I can understand why theres little enthuisiasm for Solaris around the slashdot circles, its not free and it makes money for someone else. But just as we laugh at Microsofts lack of quality, we must laud a good product. Theres no denying the graphics capabilities of OSX and Irix, network and system admin tools of Solaris, huge features and ports of Linux and rock hard stability and efficiency of BSD.
Solaris especially makes a great package with a 64-bit Sparc CPU like the cheap used Ultra 5 systems. They still need to work on the scheduler, IDE speeds and hopefully theyll put virtual terminals back in Solaris10.
I havent used AIX, HPUX or OS/360/390/400. Does anyone know of their strengths and edge over other OSes?
Re:Still a respectable beast the UNIX (Score:5, Insightful)
Yeah, their main strength (from their maker's standpoint) is that you get to pay IBM $1000's per hour or HP hundreds per hour in consulting fees for the priviledge of using them.
Really, unless you must use software or hardware that only runs on/with HPUX or AIX, don't bother. Even IBM is getting away from AIX for a lot of stuff.
Some of the biggest issues we've had are integrating with other companies who are running the above. I spent two days at an IBM facility for a conference to design how we were going to communicate with a business partner user MQ Series, since that was their IBM influenced "standard". The end result was to use MQ for "small" messages and a DIFFERENT proprietary solution for "large" messages like image files. This all because they had an IBM AS/blah blah culture.
In contrast, we spent about 30 minutes each getting all the other partner companies setup with some SSH2/SCP2 scripts to communicate with our Solaris box (even if they were running NT/2000, just had to change the version of what we sent them) and they've proven to be much less of a headache.
In summary, simplicity and standardization in Solaris, Linux or *BSD, etc... enables a lot of time and cost savings that the AIX/HPUX/OS of the world have missed.

Really though, these days, the unified config tool is the only thing that linux can't do out of the box (although webmin is a very capable alternative, if a bit slow on older kit), as the hardware support for the power3/4 systems is pretty good. Though there's some stuff that linux can't run on ( some dpx20 Bull kit, and some motorola stuff ), that older versions of aix do.

"You chose Unix as your network computing platform because you knew you were in it for the long haul," Sun said in an ad that appeared in the Wall Street Journal Wednesday. "You'd expect your IT partner to show the same kind of commitment."
"Unfortunately, our friends in Blue have a problem with licensing contracts that could make things very expensive for anyone running AIX. Fortunately, Sun is ready to help."
Sun has certainly made a commitment to one side.

It's just me, or McNealy has a terminal case of McBride envy, and is entering the final lap on the road to self-destruction?
The difference being that SUN has some value remaining, so maybe is time for shareholders to organize and depose the loony before is too late.
This man seems to view SUN just as a mean to enter pissing contests with companies he personally hates, and must be stopped.
I would hate to see SPARC going the way of Alpha.

This was actually a very good interview. For example, the Mad Hatter desktop might be out before the year is over (good stuff: Linux, GNOME, plus Microsoft filesharing and Exhange interoperability). Sun is one company who could sell something like this, because they are a very well known brandname along with an ability to offer big support. Sun is also one company who has an interest in promoting Solaris, Linux, and Windows interoperability without keeping an ace in their sleeve. If they are successful, nearly everyone benefits.

If you see a bazaar as a place where everyone sells his own small product, and a cathedral as a result of often loosely planned and re-planned work of many ages and many men, with many different skills involved...
