HP StorageWorks Enterprise File Services WAN Accelerator v3.0.7 release notes (AG421-96007, August 2007)

Increase in connection limit

The connection limit has been increased for the following models when running on 3.0 code: HP ProLiant

DL380-3010 (2400 to 3000) and DL380-5010 (4500 to 5000).

New models supported

Additional new models are supported: HP EFS WAN Accelerator DL380-3020, DL380-3520, and

DL380-6020. These models and the existing model DL380-5520 run in 64-bit mode with RiOS v3.0.

Limitations

General limitations

• Samba SMB client on Linux with either a Windows or Samba server gains only bandwidth

optimization, not latency optimization.

• An SMB mount from Linux to any CIFS server is not significantly accelerated. (It performs Scalable Data

Referencing but does not perform Transaction Prediction.)

• CIFS performance degradation occurs with multiple sets (pairs) of in-path HP EFS WAN Accelerators

(Bug #3746).

For example:

client->DL320-2010->WAN->DL320-2010->DL320-1010->DL320-2010->server

This problem is dependent on this configuration. Contact HP Technical Support for further information at

http://www.hp.com

• QoS enforcement is only available when deployed in a physical in-path deployment.

PFS limitations

For version 2.0, before you upgrade to version 2.1 or later, you must turn off the PFS auto-launch feature

and save your changes to memory. You can turn off the PFS auto-launch feature and save your changes in

the Management Console or the command-line interface (CLI).

For example:

Using the Management Console:

1. Go to the Setup: Start/Stop Services page and select Manual from the PFS drop-down list.

2. Save your configuration changes to memory in the Configuration Manager page.

Using the CLI:

1. Connect to the CLI. For detailed information, see the HP StorageWorks Enterprise File Services WAN

Accelerator Command-Line Interface reference manual.

2. At the system prompt, enter the following set of commands:

WA > enable

WA # configure terminal

WA (config) # no pfs auto-launch enable

WA (config) # write memory

You cannot change from one configuration to another in PFS deployments. The HP EFS WAN Accelerator

Management Console has been built around the Cisco CLI management model, which has the following

major characteristic features:

• Any configuration change is applied to the system immediately but not saved permanently without the

system administrator committing the configuration changes. This means after making the configuration

changes, if the system is rebooted (or the Management Console is restarted), the system comes up with

the last saved configuration.

• The system administrator can maintain different configurations under different names and can switch to

any saved configuration at any time and continue without disruptions (of course, assuming that the

saved configuration was valid and is still valid).
