Table 3: Virtual Portal Settings Fields
In this field... Do this...
Minimum Password Length Type the minimum number of characters that must be used in a CTERA Portal account password.
The default value is 7 characters.
Support Email Type the email address to which support requests should be sent.
This email address will appear in the From field of all email notifications sent by the CTERA Portal system.
Support URL Type the URL to which CTERA Portal users should browse for customer support.
This URL will appear at the bottom screen in the End User Portal interface, as well as in all email notification templates.
Email Sender's Name Type the email address that should appear in the From field of notifications sent to end users and staff by the virtual portals. For example: "CTERA Customer Service <[email protected]>".
Delete files of zero quota users after
Select this option to specify that the storage folders of customers who have no quota (for example, customers with expired trial accounts) should be deleted automatically after a certain number of days, then specify the desired number of days in the field provided.
Enabling this option helps free storage space. A notification is sent to the customer prior to deletion, prompting the customer to purchase cloud storage in order to avoid the scheduled deletion of their files.
Storage folders of over-quota users with a non-zero quota will not be deleted.
The default value is 14 days.
Reseller Portal Settings These fields are relevant for reseller portals only.
Allow self-registration Select this option to allow end users to sign up for a CTERA Portal account, by surfing to the CTERA Portal and filling in a form.
If this check box is cleared, the registration form will not appear in the CTERA Portal, and users will be defined only by an administrator.
If selected, the Require voucher and Require Email Confirmation fields are enabled.

Require voucher Select this option to require end users to supply a valid voucher code when registering a new CTERA Portal account.
Require email confirmation Select this option to require end users to confirm their
registration by email, in order for their CTERA Portal account to be activated.
This is recommended, since it ensures that the user has entered a valid email address.
Require company Select this option to require end users to specify their company, when registering a new CTERA Portal account.
Enable vouchers support Select this option to enable the use of vouchers in the CTERA Portal.
If this option is cleared, the Provisioning > Vouchers menu item will not appear in the navigation pane.
See Managing Vouchers (on page 195).
Storage Settings
Default Average Block Size Select the default average block size used by new folder groups.
The CTERA deduplication engine splits each stored file into blocks. Increasing the Default Average Block Size causes the files to be split into larger chunks before storage, and results in increased read/write throughput at the cost of a reduced deduplication ratio. Increased block size is useful for workloads that require high performance, as well as for those that do not gain greatly from deduplication (for example, where the stored files consist mostly of videos, images, and music files that are not frequently modified).
Decreasing the average block size results in better
deduplication, since the portal can better identify finer-grained duplicate data.
Note: This value applies to new folder groups only and cannot be changed for existing folder groups.

Default Average Map File Size Type the default average map file size used by new folder groups.
CTERA Portal uses file maps to keep track of the blocks each file is made of. The Default Average Map File Size represents the maximum size of file that will be represented using a single file map object. For example, if the default average map file size is set to 100MB, files of up to 100 MB will have one file map, files of up to 200MB will have two file maps, and so on.
Reducing the average map file size causes more file maps to be created per file. This may result in smoother and less bursty streaming of files; however, it will also result in some extra overhead for creating, indexing, and fetching the additional file maps.
Note: This value applies to new folder groups only and cannot be changed for existing folder groups.
The default value is 640000 KB.
Use encryption by default Select this option to specify that the Encryption check box should be selected by default in all new folder groups' settings; that is, data in newly created folder groups will be stored in encrypted format by default.
If encryption is not needed, and you want to improve performance, you can disable this option.
Note: This value applies to new folder groups only and cannot be changed for existing folder groups.
Note: Passphrase protection is only available in encrypted folders.
Use data compression by default Select this option to specify that devices should compress all blocks that they upload to the portal.
Clearing this option results in higher performance; however, more storage space will be used.
Note: This value applies to new folder groups only and cannot be changed for existing folder groups.

Remote Access Settings
Remote Access Redirection Specify whether Web clients attempting to remotely access a device should be redirected to communicate directly with the device, instead of relaying communications through the CTERA Portal. Select one of the following:
Public IP Redirect. Redirect Web clients to the device's public IP address.
Private IP Redirect. Redirect Web clients to the device's private IP address.
No Redirect. Do not redirect communications between Web clients and the device. Relay all communications through the CTERA Portal.
The default value is Private IP Redirect.
Use HTTPS for remote access Select this option to use HTTPS for remotely accessing the CTERA Portal.
