Configuration
HP ProLiant DL380 G4 Server
The HP ProLiant DL380 G4 server features 2 x 3.2 GHz processors with 4 GB of RAM, 1 x 36 GB local disk, and Windows Server 2003. All file systems are configured as NTFS.
HP OpenView Storage Data Protector 5.5
HP OpenView Storage Data Protector 5.5 is configured with default values if not specified in the following subchapters. When more than one LUN is backed up, the data is multiplexed with the described concurrency parameter (see result tables).
One “NULL” device is created for determining the max. read rate. This can be achieved by specifying “nul” in the SCSI address field of the device drive window.

Internal Database (IDB) Logging Level
The IDB logging level determines how much detailed information about backed up files and directories (name and versions) is written to the IDB.
The tests are executed with option value “Log Files”, which is appropriate for many customer environments. With this level, directories and files can be browsed before restoring. Data Protector can also fast position on the tape when restoring a specific file or directory. The information written to the IDB does not occupy much space (as with “Log All”), since not all the file details (file attributes) are logged to the database.
Please note that with “Log Files” a filename is only logged once and basically during the initial backup which requires more CPU and disk resources than the following backups, when the filename is already known.
