platform (32bit). Could you please share your thoughts on the best
available intel platforms supporting linux/Informix 10.x.
I would suggest you go to the various Linux sites, the ones with the distributions, and look at their hardware compatibility list.
Dell does sell Linux certified machines. The only problem with running a Dell is the hardware tends to be proprietary. You may want to look at an HP or Linux specific hardware vendor. Like www.emperorlinux.com - although I have not looked at their web site, just something I searched for on the web.
I would also check with the folks at Informix to find what platform would make your database fly. They may only support one or two versions of Linux. No point of getting Ubuntu Heron (my favorite at the moment) when Informix may or may not run on it.
Currently the application and Database are running on one server. We
have also been recommended to split the application & Database into
two servers. ( We retain the application on a Intel/Linux/ platform
and move the database to Non Intel based platform with latest
informix ).
I say have one server with a NAS (network attached storage) device for backups. You could have a transaction by transaction backup to the NAS so you can replay the transactions should the server fail. This is something that requires a bit more forethought as a database administrator to determine both need, and costs involved.
If you get more than one "server", use one as a workstation/backup machine. You get the use out of the machine without it being an energy sucking doorstop. I replaced all the PC's in one site with server class machines, nice graphics cards, maxed out on memory, and then backed up the main server to the other backup servers on a daily basis. (One machine called Monday, the other Tuesday, et al.)
But I highly suggest that you review what Informix and your application will need before selecting the hardware. Sometimes you get limited on your hardware options by the software you are using.
On the hardware - get the maximum amount of memory you can get on the machine, get the best video card you can get (A stable release - doesn't have to be a $800 card), and get fast hard drives. Speed is more important than space when it comes to databases.
Then have your Linux vendor tweak the disk cache to use a gig or so of memory. Unless Informix (like Oracle) wants to play GOD and do its own memory management. If so, give it a GIG for cache....provided you loaded 4GIG in a machine.
Also, run a network with bandwidth in the Gigabytes. You may want to add more cards and run load balancing to speed up the transactions to the database.
....just my thoughts....
