ONFIGURING THE HP EFS
To check for speed
and duplex errors
1. In the Management Console, click Logging to display the Logging: System Log
page.
2. Under Network click Current Connections to display the Reports: Current
Connections page.
3. Check for duplex and speed errors.
4. If you find errors, check the speed and duplex settings on your LAN and WAN
interface in the Setup: Networking - In-Path (LAN/WAN) Interface page.
5. If there is a mismatch, change the speed and duplex settings on the HP EFS WAN
Accelerator to match the interface settings.
To verify optimization
in an in-path
configuration
1. Mount a remote drive on a client machine.
2. Drag and drop a 1 MB file.
3. Drag and drop the 1 MB file again. Performance improves significantly.
Configuring Out-of-Path HP EFS WAN
Accelerators
In an out-of-path deployment the HP EFS WAN Accelerator is not in the direct path
between the client and the server. Servers see the IP address of the server-side HP EFS
WAN Accelerator rather than the client IP address. An out-of-path configuration is
suitable for data center locations where physical in-path or logical in-path
configurations are not possible. For a detailed figure, see “Choosing a Network
Deployment” on page 24.
For detailed information about out-of-path deployments, see the HP EFS WAN
Accelerator Deployment Guide.
Before You
Begin
Before you begin the configuration process, check the duplex and speed settings on the
router and switch that will connect to your HP EFS WAN Accelerator. Make sure the
settings on the router, switch, and the HP EFS WAN Accelerator match. For example,
ensure settings are auto speed and duplex on the LAN and WAN or 100 FULL on the
LAN and WAN. If the settings do not match, optimization might be degraded.
The configuration wizard automatically starts when you log into the HP EFS WAN
Accelerator command-line interface (CLI) for the first time. For detailed information
about the configuration wizard and how to restart it, see “The Configuration Wizard”
on page 34.
IMPORTANT: In an out-of-path configuration, the client-side HP EFS WAN Accelerator is
configured as an in-path device and the server-side HP EFS WAN Accelerator is configured as
an out-of-path device.
