Name Description
Remote Server Name: Radio Buttons The Remote Server name can be selected from a list of remote servers found on the
network, or manually entered in the text field. Toggle the radio buttons to choose
between automatic or manual entry.
Note: The remote server can either be a Windows server or another WXA series
appliance acting as a proxy server.
Clicking the Look Up button verifies that the name entered is registered in the DNS
server.
Local WXA Name: Text Field Enter the name of the local WXA, this will forward to the remote server. Use this name
in paths to shares to get accelerated access to remote shares. A different local name
alias should be used for each remote server.
Note: If the Update Domain Records checkbox is enabled, the 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, page 82 of this WXA.
These records can also be added later by clicking the Update Domain Records
button.
Default Cache Enabled: Checkbox When enabled (checked) shares are stored in the default cache. This option is enabled
by default.
When a file is requested, that is also available in the cache, the 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 network. This option can be overridden for individ-
ual shares.
Default Cache Read Ahead: Text Field
(Add Server Pop-up only)
The default size (measured in bytes) for read-ahead speed in the cache. The default
cache read ahead value is 61440 bytes.
To calculate this value, multiply the link latency (in milliseconds) by the measured site-
to-site bandwidth in (kilobytes per second) and divide that by the number of simultane-
ous file access users. This option can be overridden for individual shares.
Example equation: BDP/<expected number of user sessions> where BDP = link rate in
kilobytes * link latency.
Add All Shares: Checkbox When enabled (checked), all shares are added on the server for WFS Acceleration.
Otherwise, individual shares must be added manually.
Update Domain Records: Checkbox Updates any missing domain records for SPN aliases, configured remote servers to the
“Specific Trusted Host List”, and missing DNS records. Requires the user to enter
Admin credentials in a second pop-up window.
