RAID 10 performance tradeoffs and firebird

I have been configuring a fair number of Linux database servers for a line-of-business application; it runs the Firebird SQL database in server mode only (no application code at all – just DB).

All of these are the wonderful Dell PowerEdge 2950 units with the PERC6i RAID controller, and my typical configuration is 6x 146G 15k SAS drives. These are the highest-performance, highest capacity solution in 3.5″ drives.

Python, kinterbasdb and 64bit MacOSX 10.5

Now we have 64bit builds of Firebird 2.1 for MacOSX 10.5, we have issues trying to test them properly using the Firebird QMTest QA suite. This QA suite relies on Python and kinterbasdb. Currently Philippe Makowski has been able to run the tests from a 64bit Linux client. But is unable to run the tests locally. Well currently the python framework that comes with MacOSX 10.5 is only 32bit and this forces a 32bit build of kinterbasdb, since the build environment of kinterbasdb uses distutils to use the same compile switches as python. So I thought I would have a look at the issue and see if I could build a 64bit version of kinterbasdb for MacOSX 10.5.

This is how I did it…
