Measuring encryption performance
6
For example:
FabricAdmin:switch> cryptocfg --perfshow [slot] [-rx | -tx | -tx -rx]
[-interval ]
Whereby:
• Slot displays the throughput of redirected I/O flow through the EE in a given slot of the
chassis.
•
-
tx displays the transmit throughput of the redirected I/O.
•
-
rx displays the receive throughput of the redirected I/O.
•
-
tx
-
rx displays the transmit and receive throughputs of the redirected I/O.
• Interval represents a numeric value (in seconds) between refreshes.
NOTE:
• The port number mentioned in the output is the user port where virtual entities (virtual
initiators and virtual targets) are hosted.
• For accurate results, ensure that the encryption engines (EEs) are online before executing the
command. If an EE is offline, throughput results will be shown as 0.
• Even though virtual entities are hosted in a single port of encryption FPGA, I/Os for those
entities will be sprayed across the ports that belong to the same port group of the hosted port.
Each port group belonging to the encryption ASIC consists of 4 ports.
• To determine the throughput from or to a single host or target pair, the I/O from or to all other
host or target pairs should be quiesced. This is similar to measuring throughput of a single
device connected behind an NPIV port.
Example Output to determine the throughput from or to a single host or target pair:
1. Determine the user port index on which the virtual entity is hosted.
a. Get the PWWN of the virtual entity (virtual target/virtual Initiator) for which the
performance needs to be monitored by executing the cryptocfg

stat command.
