I have a server with lots of available RAM (10GB) I wanted to create an md raid 1 device that would mirror a large ramdisk (2GB) to a scsi md device. The thinking here is writes will be just as fast as always since I/O is sync to both the RAM and hard disk. However reads should be crazy fast since it should be coming from the device with the lower latency or the one that answers first (RAM). It looks like the I/O is done in a round robin setup. I get amazing reads every other test (cat'n a file) which seems it is a round robin scheme. Can this be changed somehow to prefer a device or use latency instead? __________________________________ Do you Yahoo!? Yahoo!
