HP Image Manager Server Configuration Disk Storage Required on the Server The Image Manager server must have a partition containing enough free space to contain all the virtual hard disks required by clients. A virtual hard disk consists of a hard disk image file plus a CVOL (Client Volume Overlay) write cache file that will contain all data written by the clients. The contents of the CVOL files can be retained or deleted when the clients reboot. The hard disk image will be the size of the client partition from which the image was created. The amount of disk storage needed on the Image Manager server for virtual hard disks is dependent on the mode of operation. If the clients are using a shared image in Volatile mode, Windows XP Pro and Microsoft Office 2000 can utilize less than 2 GB. Let us assume that the image size is 2 GB. Every CVOL file would use 512 MB maximum and they are deleted at each reboot. If the user is using their own unique virtual hard disk image in Normal mode, then the CVOL files will grow in size. As the Windows file system works so that every sector will be written on eventually, the worst case would be 2 GB for the hard disk image and 2 GB per client. If every sector was rewritten, the CVOL files could take up to the virtual hard disk image size. The average case would be when the virtual HD image is updated regularly (once per quarter). This would be approximately 2 GB for the HD and 800 MB per client. Some Windows settings, such as virtual memory settings, have an impact on the size of CVOL files. Configuring the License Server For detailed information on license server administration, please refer to the License Administration Guide shipped with the license server or visit http://www.acresso.com. The License Administration Guide - FLEXnet Publisher Licensing Toolkit 11.6 is available at the following URL: http://kb.acresso.com/doc/DocumentRepository/Licensing/FLEXnet_Publisher/ FLEXnet_Publisher_11.6/03_ISV/Product%20Manual/LicenseAdministration.pdf0Manual/ LicenseAdministration.pdf. Set The License Search Path Using An Environment Variable You can set the license file location on the server that runs Image Manager Server (NVDD) by setting the LM_LICENSE_FILE or HPQ_LICENSE_FILE environment variables. The environment variable can consist of the following components: ● A port@host setting, where port and host are the TCP/IP port number and host name from the SERVER line in the license file. Alternatively, use the shortcut specification, @host, if the license file SERVER line uses a default TCP/IP port or specifies a port in the default port range (27000-27009). ● A comma-separated list of three port@host specifiers identifying the license servers configured for three-server redundancy. For example: port1@host1,port2@host2,port3@host3 On UNIX, the license search path entries are separated by colons; on Windows, the entries are separated by semicolons.
