    New features

    SMBv2 and higher support

    Server Message Block (SMB) v2 and v3 are supported in Data Center Expert 7.9.0 and newer.

    Data Center Expert 7.8.1 and older do not support SMB versions higher than version 1.

    IMPORTANT: To backup DCE 7.8.1 to restore on DCE 7.9.0, you must use SMBv1 or NFS.

    Microsoft began disabling SMBv1 in Windows Updates. This can cause DCE 7.8.1 and older to be unable to back up to existing shares or mount new shares. More information about enabling SMBv1 

    See How to perform a backup in DCE

    Server access option changes

    The SSL option in the Server Access > Web server tab was removed. Private proxy and web server SSL/TLS are now included in a security policy you select.

    The System > Server Administration Settings > Server Access option now includes a Security Policy tab. You select one of the cryptographic policies supported by the Data Center Expert server:

      • Future: Experimental. Most restrictive to withstand near-term future attacks
      • Default: Secure settings for current threat models
      • Legacy: Least restrictive for maximum compatibility
      • DCE: Recommended. Custom policy, less restrictive than Default and more restrictive than Legacy

    The DCE policy is selected by default. The DCE policy is similar to the LEGACY policy except that it does not allow any RC4 or 3DES based ciphers.

    These policies are applied consistently to running services and are kept up-to-date as part of Data Center Expert software updates.

    See the documentation for security policy definitions from Red Hat here.

    Additional SNMPv3 device discovery options

    SNMPv3 device discovery options now include additional authentication and encryption types:

      • Authentication types: None; MD5; SHA; SHA-224; SHA-256; SHA-384; SHA-512
      • Encryption types: DES; AES-128; AES-192; AES-256

    UTF-8 character support for self-signed certificates

    UTF-8 characters for self-signed certificates are now supported.

    Software vulnerabilities fixed in DCE 7.9.0

      The current version of Data Center Expert is 7.9.0.196. Some customers received DCE 7.9.0.192, 193, or 194.

      DCE 7.9.0.196 addresses the following issues in previous versions of the DCE 7.9.0 release:

      • Sensor data does not populate as expected.
      • Logs can overburden the system.

    Contact support to replace the necessary files. Allowing remote access to the DCE server is required.

    OR

    Back up the DCE 7.9.0.192, 193, or 194 server. Download DCE 7.9.0.196 at the link previously provided, deploy a new server, and restore from backup. There is no upgrade option between DCE 7.9.0 versions.

    • All devices in a firmware update group are selected
      After searching for and selecting a device in the Apply Firmware Updates dialog, and then collapsing and expanding its firmware group, all the devices in the group are selected.

    • Launch to NMC 1 devices using HTTPS on the private network only
      For NMC 1 devices using HTTPS, launch to the device works from the private network only.
      This applies to devices with NMC 1 (AP9617, AP9618, AP9619) and devices with an embedded NMC 1 including, but not limited to: Metered/Switched Rack PDUs (AP78XX, AP79XX); Rack Automatic Transfer Switches (AP77XX); Environmental Monitoring Units (AP9320, AP9340, NetBotz 200)

      Alarms do not load when you access the web client from Internet Explorer 11 or Edge versions lower than 80.0. Alarms load as expected in Firefox and Chrome.
      Note: To update Edge to the latest version, go to https://www.microsoft.com/en-us/edge

    • Windows client does not restart after server change
      The Windows client does not restart after server change. After you change the server in the File > Change Server in the installed client, the client closes and does not restart. This only occurs in the Windows client. Linux client installs are not affected.
