New features

The Data Center Expert 8.0 release updates the product brand to EcoStruxure™ IT Data Center Expert.

This release contains improvements including:

• Device discovery for NetBotz Appliances
  The device discovery types in the Device >Add devices option are more descriptive and include guidance for NetBotz Appliance models.

Known Issues

We are investigating an issue where a Synchronized backup creates a Full backup and a new Full backup file. More...

• Multiple versions of DCE 8.0.0

  The current version of Data Center Expert is 8.0.0.151. Some customers received DCE 8.0.0.148 or 8.0.0.149.

  DCE 8.0.0.151 addresses the following issue in 8.0.0.149:

  Self-signed certificates cannot be removed in the System > Server Administration Settings > Server Access > Web Server display.

  Customers who updated their DCE server to 8.0.0.149 can download the 8.0.0.151 desktop client to mitigate this issue.  

  DCE 8.0.0.149 addresses the following issue in the DCE 8.0.0.148 release:

  When the Subdirectory field in the System > Server Administration Settings > Server Backup/Restore >  Backup Share Settings display contains a backslash ( \ ), the backup fails and DCE incorrectly indicates that the backup was successful.
  Replace the backslashes in the Subdirectory field with forward slashes (/) to mitigate this issue.

To update DCE 8.0.0.148 to 8.0.0.151:

Back up the DCE 8.0.0.148 server. Make sure to backup to a path that does not include a backslash.

Download DCE 8.0.0.151 at the link previously provided, deploy a new server, and restore from backup.
There is no upgrade option between DCE 8.0.0 versions.

• The DCE server update progress is not accurately displayed in the web client during the update from DCE 7.9.3 to version 8.0. The server update completes successfully.
  This will be addressed in the next release. More...

• When the DCE Security Policy is changed from Future (most restrictive) to any other policy, the DCE server must be rebooted to maintain communication with devices that use SSL.

Complete list of DCE known issues

Software update procedure

The following steps are necessary to update DCE 7.9.3 to DCE 8.0.

DCE must be at a minimum of 7.9.3 to update to DCE 8.0 If you are downloading DCE 7.9.3, you will need access to the Internet. 

You must have a valid software support contract to receive the DCE 8.0 update.  If you do not, then you will need to purchase one to receive the update.

The DCE software update files are available in the EcoStruxure IT Entitlements portal.
Log in and then click Software Updates. More information...

If the DCE update files are not available in EcoStruxure IT Entitlements, contact your local technical support to verify your support contract and get access to the update file(s) you need.

IMPORTANT: Do not reboot the server during the update.

The DCE 8.0 update performs a data migration that takes under an hour for most systems. The data migration can take longer if the system has thousands of devices and years of history, and varies based on several factors:

• Number of devices

• Number of sensors connected to those devices

• Polling interval

• Frequency at which sensor values change. For example, input voltage to UPSs can fluctuate throughout the day vs. temperature sensors in a strictly controlled environment that almost always report the same value.

You can see the status of the update on the Data Center Expert web client Home page.

NOTICE: Before beginning an update, remember to run a full backup on your DCE by going to System > Server Administration Settings > Server Backup/Restore, create a backup entry and then click Start.

1. Download the upgrade.zip file, or contact Technical Support for assistance.
   Note: The restore.iso file may be needed for later use if a re-installation is required. See Restoring using ISO Format for instructions for restoring your data from a restore.iso file from the ISO format.

2. Log in to your DCE 7.9.3 server with full server access. Select Updates > Apply Server Update.

3. Click Import to import the upgrade.zip file.
   Note: DCE 8.0 and newer only accept the zipped upgrade file.

4. The Upgrade/New Packages table will update indicating there is an update available for the DCE server. Check the "Install/Upgrade" option for the package(s) you want to upgrade. Click the Install Selected button to start the upgrade for the selected package(s). You will be prompted to confirm you want to proceed with the update. Click Install Update to start the update process. Do not reboot the server during the update process.

5. When the file transfer completes, DCE will restart and disconnect your console connection. You can point a web browser to the DCE server for status. Note: Progress is not accurately displayed in the web client for the 7.9.3 to 8.0 update. More...

6. When the update is complete, point a web browser to the DCE server, and select Download Client.

Restoring Data Center Expert using ISO Format

Warning: Only perform the steps in this section if directed to do so by a Technical Support technician.

Before You Restore:  A system restore will erase all data and restore the DCE hardware server to its factory default settings. Make sure you have a copy of all installed license keys and network settings prior to restore.

1. Download the restore.iso file to create a bootable USB key, or contact Technical Support for assistance.

   For a USB Key, follow the instructions provided in Creating a bootable USB Key (Windows or Linux machine).

2. Place the USB key in the USB port of your DCE appliance.

3. Reboot DCE.

4. When the appliance restarts the system restore process begins automatically. This process takes approximately 10 minutes for the 1U DCE Basic, 15 minutes for 1U DCE Standard or 25 minutes for 2U DCE Enterprise.
   When the restore is complete, you will be prompted to remove the USB key and hit enter to reboot the server.
   Note: If the system boots into the existing DCE version, reboot the server and access the BIOS settings. Adjust the boot sequence to boot from USB first.

5. Once DCE has restarted, configure the DCE network settings.

Migrating a Data Center Expert hardware server to a virtual appliance

Before You Migrate: To migrate a DCE hardware server to a virtual appliance, you must purchase and apply an activation key.  Additionally, you must contact APC Support for new node license keys and application license keys for the virtual appliance.

1. Perform a back up of the DCE hardware server, using the Server Backup/Restore option, accessed from the Server Administration Settings option in the System menu.

2. Deploy the demo version OVA, and configure it using the hardware equivalents for the DCE Basic, Standard, or Enterprise server from which you are migrating. The available disk space for the virtual appliance must be greater than the disk space used by the hardware server. You cannot restore to a virtual appliance with fewer CPU, fewer network adapters, less RAM, or less available disk space than the hardware server. See help for Deploying and configuring a DCE virtual appliance, and DCE virtual appliance equivalent configurations.

3. Perform a restore on the virtual appliance, using the Server Backup/Restore option, accessed from the Server Administration Settings option in the System menu. You cannot restore to a virtual machine other than the DCE virtual appliance.

4. Apply the activation key to the virtual appliance.

5. Log in to the DCE client. In the "License Keys" display, accessed from the Server Administration Settings option in the System menu, apply the new node license keys and application license keys you received from APC Support.
