Thanx for the info. I'm also interested to know if anyone knows whether I should get better preformance under the following conditions: My application write loads (in order of MB) of data to disk. It can go through the file system or just write straight to disk. While running some benchmarks I saw that a cheap scsi quantom was getting better preformance then a seagate cheeta! This was on an adaptec 2940UW host. I was going to switch to an IBM drive that out do the cheeta, but was considering of striping two disks to gain better speed. Is this likely? Does anyone have disk I/O benchmarx anywhere? Thanx for the time, Jambi _______________________________________________ Jambi Ganbar | (619) 8220938 | jambi@nlanr.net San Diego SuperComputer Center ________________________________________________ On Thu, 30 Apr 1998, Tom wrote: > > On Thu, 30 Apr 1998, Jambi wrote: > > > does anyone know what models of DTP raid cards work with 2.2.5 or 2.2.6 > > kernels? > > Thanx, > > Jambi > > All of them.
