 1U servers with serial ports I've got a stack of old desktop PC's running data collection apps in a location we are going to rework. I thought I'd neaten up things by replacing these with a nice rack and some 1U servers. Problem is, looking at the Sun site, it does not appear that they offer a fairly low end 1U unit with an RS-232 port. I need that for these data collection machines. Suggestions? -- "They that would give up essential liberty for temporary safety deserve neither liberty nor safety." -- Benjamin Franklin      |

The serial ports use an RJ-45 connector, but come with an adaptor to the DB-9 or DB-25 connectors normally used for RS-232. This way you can run the serial cables using your existing twisted pair network. The v100 is light, low on power consumption, and a bit noisy. It isn't that hot on number crunching, but if all you are doing is data collection it might be what you want. The v120 is pretty much the same, but with SCSI. -- Dr Tristram J.

I'd prefer X86 for this application, as the PC's are runing FreeBS, and I think I will be better off on X86 with this OS. It's more mainstream for them, although I do think there is a port to SPARC. I suppose I _could_ port the app to Solaris if it's a big win to do that. -- "They that would give up essential liberty for temporary safety deserve neither liberty nor safety." -- Benjamin Franklin |

Solaris 10 has the usbser_edge driver and I believe Solaris Express has even more -Raf |

I use them and they can go up to 115200 on all 64 channels! Then you only have one box and can get a good for that, good ones are a U45 or Blade 2500 if you can use a WS otherwise a V240 or a T2000! /michael |

We have been associating one data stream with one computer. Moslty because we were recycling old P2's to do this. But also beacuse our "customers" access teh data from aa Apache server on the machines. Thus one machine name == one data source. Of course I could probably do soemthing wiht virtual hosts ... But at that point the job becomes a bit bigger than just replacing old hardware with new more compact hardware, shich is the original plan.
