Remote control considerations

Be aware of security, performance, and keyboard considerations that are related to accessing managed servers using a remote-control session.

Security considerations​

The user account that is used to start the remote-control session must be a valid user account that has been defined in the Lenovo XClarity Administrator authentication server. The user account must also have sufficient user authority to access and manage a server.

By default, multiple remote-control sessions can be established to a server. However, when you start a remote-control session, you have the option to start the session in single-user mode, which establishes an exclusive session with the server. All other remote-control sessions to that server are blocked until you disconnect from the server.

Note
This option is available only if there are currently no other remote-control sessions established to the server.
To use Federal Information Processing Standard (FIPS) 140, you must enable it manually by completing the following steps on your local system:
  1. Find the provider name of the FIPS 140 certified cryptographic provider that is installed on your local system.
    Tip
    For more information about FIPS 140 compliance, see the FIPS 140 Compliant Mode for SunJSSE website.
  2. Edit the file $(java.home)/lib/security/java.security.
  3. Modify the line that includes com.sun.net.ssl.internal.ssl.Provider by appending the provider name of your FIPS 140 certified cryptographic provider. For example, change:
    security.provider.4=com.sun.net.ssl.internal.ssl.Provider

    to:

    security.provider.4=com.sun.net.ssl.internal.ssl.Provider SunPKCS11-NSS

Performance considerations​

If a remote-control session becomes slow or unresponsive, close all video and remote media sessions that you have established with the selected server to reduce the number of open server connections. In addition, you might increase performance by changing the following preferences. For more information, see Setting remote-control preferences.
  • KVM
    • Decrease the percentage of video bandwidth that is used by the application. The image quality of the remote-control session will be reduced.
    • Decrease the percentage of frames that are refreshed by the application. The refresh rate of the remote-control session will be reduced.
  • Thumbnails
    • Increase the thumbnail refresh interval rate. The application will refresh thumbnails at a slower rate.
    • Turn off the display of thumbnails completely.

The size of the remote-control session window and the number of active sessions might affect workstation resources, such as memory and network bandwidth, which can influence performance. The remote-control session uses a soft limit of 32 open sessions. If more than 32 sessions are open, performance might be severely degraded, and the remote-control session might become unresponsive. You might see performance degradation with fewer than 32 open sessions if resources, including network bandwidth and local memory, are not sufficient.

Keyboard considerations​

The remote-control session supports the following keyboard types:
  • Belgian 105-key
  • Brazilian
  • Chinese
  • French 105-key
  • German 105-key
  • Italian 105-key
  • Japanese 109-key
  • Korean
  • Portuguese
  • Russian
  • Spanish 105-key
  • Swiss 105-key
  • UK 105-key
  • US 104-key
