Chapter 12: Status Page

The Status page provides information about the following:

• Updating the Nasuni Edge Appliance software to the latest release.

• Status of jobs bringing data into the cache, such as Bring into Cache and Auto Cache.

• Unprotected files currently in the cache.

• Network status.

• Platform status.

• CIFS status.

• NFS status.

• FTP status.

Note: The Status page, and all other pages of the Nasuni Edge Appliance user interface, might look different to different users. Also, different menus and actions might be available for different users. This is because different users are assigned different permissions, based on their roles in the role-based access control system. See “Users and Groups” for details.

Note: If this Nasuni Edge Appliance is under the control of the Nasuni Management Console, menus and menu choices might look different, because you use the Nasuni Management Console to perform these tasks.

Software Updates

When a newer version of the Nasuni Edge Appliance software is available for installation, you can update the software from the Status page. When you update your software, your Nasuni Edge Appliance is updated to the newer version.

If updates are not available, a page appears telling you there are no updates at this time.

Warning: Do not attempt to restore from a virtual machine snapshot or backup.

Caution: Do not power off or reboot during a software update.

Caution: Updating the software disconnects all users currently using the Nasuni Edge Appliance. The Nasuni Edge Appliance can take several minutes to reboot. The time to reboot can be longer if one-time upgrade operations are necessary.

Note: Nasuni does not recommend applying software updates during your normal business hours, because this can disrupt access. Apply software updates during off-hours.

Tip: Check the release notes of all releases between your current release and the most recent release. See “Viewing the Nasuni Edge Appliance Release Notes” for details. You can also view Release Notes in Release Notes Guide.

Important: The version of the Nasuni Management Console must support the version of the Nasuni Edge Appliance that the Nasuni Management Console is to manage. If this Nasuni Edge Appliance is joined to a Nasuni Management Console, update the Nasuni Management Console software before updating the Nasuni Edge Appliance software.

For details, see “NMC version”.

Tip: The version of the Nasuni Edge Appliance software, such as 9.3, appears on the bottom right of each page.

Tip: You can configure the Nasuni Edge Appliance to apply updates automatically.

Tip: It is a best practice to perform a Nasuni snapshot before performing an update.

Tip: If updating the Edge Appliance software from a version before 9.0 to version 9.0 and later, for NFS volumes and multiprotocol (CIFS and NFS) volumes that are using the Advanced mode of Global File Lock, change the mode of Global File Lock before performing the update. NFS volumes and multiprotocol (CIFS and NFS) volumes do not support the Advanced mode of Global File Lock for version 9.0 and later.

Tip: Updating to Edge Appliance version 9.12 includes automatically upgrading the PostgreSQL databases. For this reason, expect the reboot of the Edge Appliance after the 9.12 update to take longer than usual. The splash screen on the appliance console displays a message indicating that the update is in progress and that you should avoid rebooting or removing power.

Tip: Updating the Edge Appliance version from 9.9.5 or 9.10.2 or earlier to 9.12 includes automatically migrating to a new and more efficient volume schema. For this reason, expect the reboot of the Edge Appliance after the 9.12 update to take longer than usual. The duration depends on the number of volumes and the size of the volume databases. The splash screen on the appliance console displays a message indicating that the update is in progress and that you should avoid rebooting or removing power.

Tip: As part of the 9.12 release, a pre-update check has been added to verify enough free available cache space to initiate the update successfully. Therefore, you might receive a warning message when trying to update to 9.12.

Full Disk Encryption (FDE) (hardware appliances only)

The goal of Full-Disk Encryption is to provide encryption for data at rest in the Nasuni Edge Appliance. While good physical security can protect access to data in the Nasuni Edge Appliance in a data center, data can also leave the data center through drive replacements, due to theft or failure. Encryption of data at rest makes sure that no data can leave the Nasuni Edge Appliance by someone removing a drive and the drive remaining usable.

Nasuni includes self-encrypting drives (SEDs) in Nasuni Edge Appliance hardware appliances, NF-400 and above.

SEDs allow for hardware-based encryption of data at rest with little or no performance impact over non-SEDs. The encryption must be “turned on”; otherwise, SEDs behave just like non-SEDs. Nasuni does not enable the Full Disk Encryption feature for clients. Clients enable the Full Disk Encryption feature themselves when they configure the feature.

Tip: Full Disk Encryption must be made available in the client license before encrypting SEDs.

Full Disk Encryption is available in the client license by default.

Warning: After Full Disk Encryption is enabled, it cannot be disabled.

On the Platform Status page, if Full Disk Encryption has been made available in the license, an indicator shows that the Nasuni Edge Appliance is in one of these states:

• An unlocked lock icon   indicates that FDE is available, but not enabled: the disk is not encrypted.

• A locked lock icon   indicates that FDE is enabled: the disk is encrypted.

Clients must provide a password when encrypting the Nasuni Edge Appliance and are responsible for keeping that password for possible, but unlikely, future use. Nasuni does not provide passwords or escrow them for clients for this feature. The password requirements are:

• 8 to 32 characters.

• Must contain at least one uppercase letter. Case-sensitive.

• Must contain at least one lowercase letter. Case-sensitive.

• Must contain at least one number.

• Must contain at least one non-alphanumeric character (such as < > @ +). The space character is not permitted.

An SED and a non-SED are interchangeable when the SED encryption is not enabled. However, a secured SED cannot be used in place of a non-SED.

Enabling Full Disk Encryption

Warning: After Full Disk Encryption is enabled, it cannot be disabled.

To enable Full Disk Encryption, follow these steps:

1. Click Enable Full Disk Encryption. The Enable Full Disk Encryption dialog box appears.

   

2. Enter the Password with which to encrypt the SEDs, and verify the password.

   Warning: You must record the password securely. Nasuni cannot escrow or recover the password.

3. Click Save.

Full Disk Encryption is enabled for the SEDs.

Changing the Full Disk Encryption Password

To change the Full Disk Encryption password, follow these steps:

1. Click Change FDE Password. The Change Full Disk Encryption Password dialog box appears.

   

2. Enter the Current Password.

3. Enter the New Password with which to encrypt the SEDs, and verify the password.

   Warning: You must record the password securely. Nasuni cannot escrow or recover the password.

4. Click Save.

The password for Full Disk Encryption changes.

CPU Activity

To select the time scale, from the drop-down list, select either Previous Hour or Previous Day.

Memory Usage

On the Platform Status page, a chart of memory usage vs. time appears.

The graph displays the memory usage (in GB or similar units) vs. time of day. If you hover the mouse over any part of the chart, a label appears displaying details about the memory usage at that date and time.

Tip: Due to the way Memory Usage is calculated, the display can show spikes that do not reflect the actual values. Refreshing the display can remove these spikes.

Note: Nasuni Edge Appliances and the NMC display the size of data in base 10 units (including MB = 1,000,000 bytes, GB = 1,000,000,000 bytes, and TB = 1,000,000,000,000 bytes).

In contrast, some platforms display the size of data in base 2 units (including MB = 1,048,576 bytes, GB = 1,073,741,824 bytes, and TB = 1,099,511,627,776 bytes).

For example, a file that Nasuni displays as 10 MB would be displayed by some platforms as 9.53 MB.

To select the time scale, from the drop-down list, select either Previous Hour or Previous Day.

     • Volume: The volume of the NFS export. Clicking this link opens either the NFS Exports page for this volume, if this Nasuni Edge Appliance is not under the control of the Nasuni Management Console, or the Home page (see “Home Page”), if this Nasuni Edge Appliance is under the control of the Nasuni Management Console.

     • Path: The path in the volume to the NFS export.

     • Export Name: The name of the NFS export. Clicking this link opens either the Add NFS Export / Edit Settings page for this volume, if this Nasuni Edge Appliance is not under the control of the Nasuni Management Console, or the Home page (see “Home Page”), if this Nasuni Edge Appliance is under the control of the Nasuni Management Console.

FTP Status

You can view FTP/SFTP directories for volumes that have the FTP/SFTP protocol enabled. You can also view the status of FTP/SFTP clients.

Note: Nasuni supports SFTP, the SSH File Transfer Protocol. This is not the same as FTPS, the File Transfer Protocol over SSL.

Tip: You can ensure that the SFTP (SSH File Transfer Protocol) protocol is used, rather than the FTP protocol, with the Firewall page in the Edge Appliance UI. For each Traffic Group, select SFTP and deselect FTP.

Tip: In order to access data using the FTP/SFTP protocol, the following steps are necessary:

• Create a volume.

• Enable the FTP protocol on the volume.

• (Optional) Configure FTP settings.

• Add a new FTP/SFTP directory.

• (Optional) Create a permission group that has storage access. See “Adding Permission Groups”.

• (Optional) Create a user in a permission group that has storage access. See “Adding Users”.

• Access files using the FTP/SFTP protocol. See “Accessing data using the FTP/SFTP protocol”.
