Hi, I had a question regarding SCSI disk driver. Does SCSI disk reorder the requests it gets from the OS. I always believed that the OS orders the requests based on some algorithm (say elevator, SSTF etc.) and the disk just picks the request from the head of the queue and services them in FIFO order. But when I traced the sector number of the request that are sent to the device and the sectors that get serviced dont seem to be in this FIFO order. it more likely seems to be in a elevator fashion. So does the SCSI driver has some intelligence that reorders the requests to increase throughput. thanks a lot, Raghu. -- Kernelnewbies: Help each other learn about the Linux kernel.
