HP MPX200 Multifunction Router User Manual

Disable compression if:
◦
You know that the underlying data is not compressible.
◦
The available WAN bandwidth is greater than 600 Mbps, but you observe performance
degradation.
You can determine the compression ratio on the router based on the output from the show
perf byte
command and the following calculation:
Compression ratio = 1 – (GbE port throughput ⁄ FC port throughput)
◦
A difference of greater than 25 MB between the throughput on the FibreChannel port
and the throughput on the GbE port indicates a 'good' compression ratio.
◦
A zero or negligible difference between the throughput on FC port and the throughput
on the GbE port indicates a 'bad' compression ratio.
•
Breakup IO: Enable this option to leverage the Native IP-based write acceleration of the router.
HP recommends that you enable breakup to achieve better I/O performance.

All attribute values for that have been changed will now be saved.
Follow these steps to change the array properties using the CLI. Note that all data migration
operations are authorized only to the migration administrator session, miguser. For more information,
see
.
To set array properties in the CLI:
1.
Log into the MPX200 as guest and enter the password.
2.
Open a miguser session using the following command:
nl
miguser start -p migration (
nl
The default password for miguser is migration.)
3.
To access the array properties, enter the following command:
nl
set array
4.
Select a target ID by entering its index number.
5.
At the prompts, modify as needed the symbolic name, target type, array bandwidth, maximum
concurrent I/Os, I/O pacing, and load balancing for the source and destination arrays.
