SCSI block or streaming commands

Postby Zen » Wed Nov 30, 2005 1:16 am

Is there any advantage(s) using SCSI block commands (SBC) against SCSI
streaming commands (SSC) over Fibre Channel for large file transfers
(streaming)? Which one is more efficient? Does any one have seen such
topic being discussed or analyzed?

Your input and direction is truly appreciated.

Regards,

In additon to my previous question just for clarification.
Our application uses a solid-state disk which can emulate either a disk
for a
tape for large file transfer or data streaming. We would like to find
out which
emulating mode (disk or tape and thereof its associating SCSI protocol
) is more efficient for large file tranfer or data streaming in FCP
(SCSI
protocol for Fibre Channel) network. Does anyone know any related
analysis
is done somewhere?

Benchmark it?

There's no difference between the protocols as far as efficiency, so any
difference you'll see will be due to the emulation.
