Hi Donald, Hi The Lee-man, Thanks for the reply. Both replies were helpful and both replies actually clarified my concepts. And I realized, the question was not clear....You were kind enough to reply in detail even when the question of was not clear !
*The Lee-man*, your guess was right. I was thinking something like that and I realized it makes no sense. *Donald*: Yes, you are right. I took this point of yous "*then doing normal I/O to that iSCSI disk will provide all the traffic you will typically need*"....the wireshark showed me ! I'm a novice in Open-iSCSI yet very much interested in it. Please excuse my simple questions. It is written, Open-iSCSI acts as "*kernel driver*" between "*block layer*" and "*network layer*". Therefore following two questions: - Linux block layer perform IO scheduling IO submissions to storage device driver. If there is a physical device, the block layer interacts with it through SCSI mid layer and SCSI low level drivers. So, how *actually* a software initiator (*Open-iSCSI*) interacts with "*block layer*"? I will be really grateful if you can explain me. - What confuses me, where does the "*disk driver*" comes into play?
