HP SureStore CD-ROM Server/Tower, Server, and Expansion Tower - The CD-ROM Performance Levels Drop
The transfer time of data for a CD-ROM becomes increasingly high when several users access a CD-ROM simultaneously. Performance decreases.
The local area network (LAN) (at bytes per second, maximum throughput) might be causing the slower transfer time. Either reinstall in a switched network or restrict the number of users of a CD-ROM by setting the UserLimit access parameter in the access files.
Go into Statistics access folder (if using web browser, go into Management/Statistics) and view the cache hit ratio. A higher cache hit ratio indicates that the slower transfer time might be in the server.
Check the data transfer rate of a CD-ROM drive by performing a diagnostic test.
The diagnostic test tests the CD-ROM server’s memory and the operation of the connected drives.
Before using the diagnostic test:
Users who are currently accessing the CD-ROM server will be interrupted.
The diagnostic test is only available for the first hour after you turn on or restart the CD-ROM server. Also, you must restart the CD-ROM server before you can repeat the diagnostic test.
To test the data transfer operation of a CD-ROM drive, the drive must have a CD-ROM inserted with a file larger than 10 megabytes (MB) on it.
Conduct the diagnostic test as follows:
If using a Web browser, start the browser and enter the URL of the server’s diagnostic page (for example, http://<IP address>/config/html/diag.htm).
Make sure that a suitable CD-ROM is inserted into each of the drives whose operation is to be tested. To test the data transfer operation of a CD-ROM drive, the drive must have a CD-ROM inserted with a file larger than 10 MB on it.
To start the diagnostic test, simply reload the diagnostic page in the Web browser. The test might take several minutes. When it is complete, you must reload the diagnostic page to display the results.
note:Any further reloading of the diagnostic page will simply show the same test results. You must restart (power cycle) the CD-ROM server before you can repeat the diagnostic test.
