SBP2 Query

Let's say an application on top of SBP2 wants to transfer a file from =
target to initiator. So in this case depending on the size of the file =
the target will send  multiple write request to initiator. I wanted to =
know that how does the target side application interact with the SBP2. =
On the initiator side the SBP2 will make a command ORB ( assuming that =
it has alreadyt logged into target) and signal to target. Now target =
reads the ORB and finds it is for data write to initiator. Now on the =
target side SBP2 has to take data from application and then it has to =
send to initiator. Do the target has to make some kind of ORB and then =
send the request to initiator or the async block/quadlet write could =
directly be done.=20
=20
SBP2 says that a node can act as target and initiator simultaneously. I =
wanted to know whether for a single transaction(say initiator wants to =
read qaudlet data from target) the switching to target/initaitor is =
necessary.=20
Or the switching is done when same node is interacting with two =
different node and acting as initiator for one and target to other.

 SBP2 Query
  
 Let's say = an application=20 on top of SBP2 wants to transfer a file from target to initiator. So in = this=20 case depending on the size of the file the target will send  = multiple write=20 request to initiator. I wanted to know that how does the target side = application=20 interact with the SBP2. On the initiator side the SBP2 will make a = command ORB (=20 assuming that it has alreadyt logged into target) and signal to target. = Now=20 target reads the ORB and finds it is for data write to initiator. Now on = the=20 target side SBP2 has to take data from application and then it has to = send to=20 initiator. Do the target has to make some kind of ORB and then send the = request=20 to initiator or the async block/quadlet write could directly be=20 done. 
  
 SBP2 says that a node can act as target and = initiator=20 simultaneously. I wanted to know whether for a single transaction(say = initiator=20 wants to read qaudlet data from target) the switching to = target/initaitor is=20 necessary. 
 Or the switching is done when same node is = interacting with=20 two different node and acting as initiator for one and target to=20 other.
