Agreed. The profile 0.52 is describing TRANSPORT_CAPABILITIES
command to ease to support flow control. Right? However when
we choose “multiplex connections over a login”, then can we use
same method? If not, do you prefer connections over multiple LUNs?

“outstanding requests” on PC OS platform. Are you saying how many
outstanding ORBs can be supported at once over multiple LUUs?

Thank you,
