WFS Acceleration

 

Enables WFS Acceleration and allows user to choose the IP address to associate with the service. See “” section for details.
Provides diagnostic tools for the WFS Acceleration service. See “Tools Tab” sec­tion for details.

Configuration Tab

The Configuration tab allows you to enable the WFS Acceleration service and select a public IP address for the WXA series appliance.

Figure 9
Configuration Tab

Enables (checked) the WFS Acceleration service on the WXA series appliance. Enabled by default.
Sets the address object that represents the IP address that the SonicWALL WXA series appliance will use when connecting to servers and clients.
 
Note
You can verify the WFS Acceleration status on the WAN Acceleration > Status page in the WFS Acceleration Panel.

Domain Details Tab

The Domain Details tab allows you to configure the SonicWALL WXA series appliance to match that of the Microsoft Windows Domain it is to join. The SonicWALL WXA series appliance may automatically discover the domain details if the DNS server configured on the SonicWALL NSA/TZ series appliance is a domain controller and the DNS server is correctly configured in the domain.

 
Note
The user interface is different if the domain name is not auto-discovered. This requires you to enter the basic details for a domain in a different table.
Figure 10
Domain Details Tab (Name Not Auto-discovered)

Figure 11
Domain Details (Name Auto-discovered)

 

The fully qualified domain name (FQDN) for the Windows domain that the Son ­ icWALL WXA series appliance uses for file sharing. To change the FQDN, you must unjoin the domain. Click the Edit button to modify the FQDN, Figure 12 .
 
 
If you configured the FQDN at initial setup, the SonicWALL WXA series appliance should auto-discover the corresponding NETBIOS domain.
 
Note
Changing the FQDN or the NETBIOS Domain after joining the Windows domain requires the device to rejoin the domain.
Displays the hostname for the SonicWALL WXA series appliance. If an account is created on the domain using the SonicWALL WXA series appliance hostname, the SonicWALL WXA series appliance attempts to join the domain. Click the Edit button to modify the hostname, Figure 13
 
Note
Changing the hostname requires the old computer account to be manually deleted from the domain controller.
The FQDN of the Kerberos server on the Windows Domain. The port number defaults to 88. This server is typically the domain controller.
To edit the server name, you must first unjoin the domain, and then click the Edit button. The Kerberos Server pop-up window appears, Figure 14 .
 
Sets the Lightweight Directory Access Protocol (LDAP) server on the network. The port number defaults to 389. This server is typically the domain controller.
 
(Read-only) Indicates an account matching the hostname of the device is found on the domain. There are three pre-requisites before the SonicWALL WXA series appliance can join the domain:
2.
SELF must be delegated to join the domain,
When an account is created on the domain using the devices hostname, the device discovers the domain and should configure itself.
(Read-only) Indicates that the computer account of the SonicWALL WXA series appliance on the Domain Controller is trusted for delegation. When this checkbox is checked, the computer account IS trusted for delegation.
This is a necessity and requires the administrator to configure the domain control ­ ler to confirm that the SonicWALL WXA series appliance can be trusted for dele ­ gation.
Displays the server that the SonicWALL WXA series appliance will synchronized its clock with. This server is usually the Domain Control because the SonicWALL WXA series appliance must closely match that of the Domain Controller.
Click the Edit button to modify the server, Figure 15 .
(Read-only) Displays the current primary DNS server IP address, which must be a domain DNS server for WFS Acceleration to function properly.
Configures the WFS Acceleration service in more detail with Client Signing, Server Signing, and Max Transmit, which affect the CIFS packet size, Figure 16 .
The SonicWALL WXA series appliance joins the domain (becomes part of the domain) that is identified in the FQDN. The Join Domain Pop-up Window is dis ­ played, Figure 17 .
Tests the WFS Acceleration service. If the WFS Acceleration service is not work ­ ing correctly, reconfigure the domain details, and then retest.

•
Add New Server... Link — When clicked the Add Server pop-up is displayed, Figure 20 . This window allows you to configure a new remote server.
 
•
Server Details Table — This table provides details on the servers that are configured with WFS Acceleration. It consists of the following details:
 
–
Remote Server Name Column — Displays the name of the remote server.
 
–
Local Device Name Column — Displays the name of the local device (WXA series appliance).
 
–
Default Cache Enabled Column — Displays whether caching is enabled (checked).
 
–
Default Cache Read Ahead Column — Displays the read-ahead speed in bytes.
 
–
Configure Column — Displays an Edit and Delete buttons. Click the edit button to modify the configuration of the server. Click the delete button to remove the server from using WFS Acceleration. When the Edit button is clicked, the Edit Server Details window is displayed, Figure 20 .

The name of the remote server. If you do not remember the name, select a name from the drop-down which displays a list of the detected servers (not always available).
 
Note
The remote server can either be a Windows server or another SonicWALL WXA series appliance acting as a proxy server.
The name of the local device. If you do not remember the name, select a name from the drop-down which a list of the detected names (not always available).
 
Note
The SonicWALL WXA series appliance will attempt to create a DNS record for each of the service principal name (SPN) aliases. The local device name must resolved to the public IP address. The DNS Server IP address is identified on the Domain Details Tab .
When a file is requested, that is also available in the cache, the SonicWALL WXA series appliance serves the data from that cache as long as the cache file is valid. If the original file has changed, the parts of the cache that are still valid may be used. This process reduces the need for data to be sent over the net ­ work. This option can be overridden for individual shares.
Default Cache Read Ahead: Text Field
(Add Server Pop-up only)
To calculate this value, multiply the link latency (in milliseconds) by the meas ­ ured site-to-site bandwidth in (kilobytes per second) and divide that by the number of simultaneous file access users. This option can be overridden for individual shares.
