Linux ServerWatch writes about the slow but sure death of UNIX by the onslaught of Linux and customers moving from older proprietary UNIX systems to commercially supported open source enterprise Linux distributions. "Linux does have one killer feature that is driving the switch: lower cost. Many companies are discovering Linux to be extremely attractive from a cost perspective. Take the experience of Sabre, a travel company that replaced Solaris with Red Hat Enterprise Linux (RHEL) running on x86 machines, resulting in lowering costs 90 percent (with a three-fold speed gain to boot). These potential cost savings, which include hardware maintenance costs savings, are not to sniffed at."

Despite all of the critics and not-agreeing that UNIX is dead, it's going down, I think in terms of sales - If I'm to buy systems, I'd likely choose / assemble hardware of my own, x86 based, and then install SLES or RHEL on top of it, with commercial support, if I need it. It's definitely less expensive than AIX, HPUX, Solaris, etc. For example consider this - adding 4 gigs of RAM on P4/5 IBM server costs around 800-1000$ ? How about I purchase simple RAM module for 50-100 for my x86 based machine ?
Also, no one could convince me that old proprietary UNIX systems are better for supercomputing and large-scale systems - see Google and Cray.

Old Sun stuff is not optimal for super computing stuff, that is correct. Linux is simpler to tailor for super computing than Solaris kernel. But Linux scales quite bad in everyday work. If you do number crunching, a simpler Linux kernel suits better. Unless you want to tailor the well scaling Solaris for that, of course. But Solaris is more complex and this is not easily done. Of course SUN could tailor the Solaris kernel for number crunching if they want to. It is easier to tailor a kernel to a specific simple task. And it eases the task if the kernel is simple enough to modify too, that is Linux. It has a naive approach as you can see by the fact that Linux becomes unstable when you stress it hard.

It seems that lots of companies goes to Linux and when they grow, they notice that Linux doesnt cut it, with high utilization. Then they switch to Solaris and report no problems.

And Solaris support is cheaper than Linux support. And you can of course install Solaris on the same hardware as Linux. The good thing is that when you know Linux or Solaris, it is quite easy to switch OS. They are quite similar - compared to, say, Plan9 vs Windows or Windows vs Haiku. I prefer Solaris + ZFS on my home fileserver than Linux + ext3. Who wants silent corruption?
