Hello Vlad, It is sure Raid 0 with 3 * 600 GB Toshiba SAS. I only installed the server today. I did not use the LSI Raid BIOS for configuration but the "server view" installation kit from the producer. So I will have to look up stripe size and BBU status.
Next week I will also apply a benchmark test and then write results here. I will also try on other hardware. I have 2 other new servers for other uses but so far still idle, so I can play a bit. I wanted to drop you a message anyway, because if I understood correctly in Prague you do not have too many different hardware systems for testing, so maybe if you have a test database and a prepared benchmark I can run some tests with FB 3. > > Hi, André ! >> [Old] >> Server 2003 x86 no service packs >> Xeon with 4 GB RAM >> Classic 1.5.4 (x86, of course) >> Raid 0 on 2 * 500 GB SAS (though this is from memory, I should look it >> up...) >> >> [new] >> Server 2008 R2 x64 SP1 >> Xeon with 8 GB RAM (I will shortly add +8) >> Classic 2.5.3 x64 >> Raid 0 on 3 * 600 GB SAS > > Raid 0 ?
