Overview
This iperf-based Network Performance Tool executes a synthetic workload on the network to evaluate the performance characteristics available between the Delphix Engine and Target servers.
Prerequisites
The network performance tool measures network performance between a Delphix Engine and an environment host. You must have added an environment in order to use this tool.
This transmission control protocol (TCP) throughput test uses TCP port 50001 by default. The port can also be configured on a per-test-run basis. For the duration of a given throughput test, a server on the receiver will be listening on this port. For a transmit test, the receiver is the remote host; for a receive test, the receiver is the Delphix Engine.
Running the Network Test via CLI - Latency
The network latency test measures network round-trip latency by transmitting ICMP echo requests (like the ping utility) and measuring the time to receive replies from the remote host. To execute a test:
- Login as a domain user to the Delphix Engine CLI using ssh.
Create a network latency test.
delphix> network test latency delphix network test latency> create delphix network test latency create *>
You must set remoteHost to the name of an environment host already configured in the Delphix Engine. (You should press tab after the "=" (equal sign) to auto-populate and confirm registered destinations). Use 'get' to see other optional arguments. Modify the test parameters as needed and commit to start the test.

Running the Network Test via CLI - Throughput
The network throughput test measures sustained throughput using a synthetic workload to or from a remote host. To execute a test:
- Login as a domain user to the Delphix Engine CLI using ssh.
Create a network throughput test.
delphix> network test throughput delphix network test throughput> create delphix network test throughput create *>
You must set remoteHost to the name of an environment host already configured in the Delphix Engine. Use 'get' to see other optional arguments. Modify the test parameters as needed and commit to start the test.

Delphix Session Protocol Test from Primary Engine to Replication Engine
Delphix uses the Delphix Session Protocol (DSP) protocol to communicate between primary and replication engines.
- To execute a test via the CLI:Login to Delphix Engine using a Delphix administrator account such as delphix_admin.
As soon as you login, you will get prompt with engine name.-bash-4.3$ ssh delphix_admin@delphix Password: delphix>
Create a dsp test
delphix> network test dsp create
- Set the destinationType to DELPHIX_ENGINE to do a DSP test between two Delphix Engines. The default is REMOTE_HOST which executes a DSP test between a source or target host and the Delphix Engine.
