Hi Mathias, Over the years I had been accustomed to running my SpectroServers on Solaris, and my Oneclicks on Windows2003. Just a personal preference, for ease of installation and maintenance. I moved to Linux on 8.1 for the same reason most people did, expense. There were some hardships at first, since 8.1 did not have all the components of the Sun and Windows versions. But since 9.0 with all the features incorporated, Linux has been very reliable and I do not see myself moving back to Solaris. I still run my oneclicks on Windows2003, only because they are built as V-motion and load balanced. Of my 7 primary SpectroServers, they are running RH5.4 on dell 1950's with 2-quad cores and 8 gigs of ram. My largest database maintains about 175,00 models and the smallest is about 90,000 models. As mentioned before all 7 of my Fault-tolerant systems are running Linux 5.4 on VMware. Each has 4 dedicated processors, and a committed 8 gigs of Ram. They are the only thing dedicated on the ESX, and the performance when failed over is very pleasing. I was doubtful at first to make the Linux and the Vmware plunge, but I have not regretted it.

We hit them in development but they are long gone, we have had 32 landscapes(16 primary 16 backups) running in a Vmware cluster across 4 servers, all with 4G of ram allocated and hundreds of thousands of models. Tomcat seems to perform much better too. This is on Redhat 5.4 64-bit, even though spectrum is still 32-bit we wanted to be ready for 10.x or 11.x that might include this support or multiple instances without upgrading /re-installing the o/s. > > If you are noticing anything specific please let us all know about it. But do you have any idea how it compares to Spectrum on Solaris? We aren't using linux for any portion of our Spectrum installation right now. Our current hosts (all Solaris) are due for replacement, so I'm looking into whether we can save money by switching to linux. I want to make sure that the extra effort will actually get us cost savings, and we wont have to get more hardware to get the same performance.
