Measuring encryption performance

6

For example:

FabricAdmin:switch> cryptocfg --perfshow [slot] [-rx | -tx | -tx -rx]

[-interval <time in seconds>]

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
