Figure 1. The HP StorageWorks 6000 Virtual Library System emulates popular HP tape drives and libraries 
 
 
An additional benefit of implementing an HP VLS6000 solution is better utilization of your existing 
physical tape hardware—doing more with less. Backup to physical tape from the HP VLS6000 can 
now take place at your convenience during the day, with the same physical library being used during 
the night for backing up the faster parts of your infrastructure (databases, and so on).  
The HP VLS6000 integrates seamlessly into heterogeneous backup environments because the backup 
application thinks it is backing up to physical tape. Because of its optimized design, the capacity and 
performance of the HP VLS6000 grow together. The HP VLS6000 can offer the best cost per MB/sec 
value in its class. 
The HP VLS6000 manages the virtualization node and disk array as a single device, using  
HP StorageWorks Command View VLS to minimize the management overhead of your IT operation.  
Because the HP VLS6000 integrates seamlessly into existing backup and recovery processes and 
appears as a physical library to the backup software, normal backup application software licensing 
applies. This is typically based on drive count or slot count. Some major backup application ISVs, 
such as HP OpenView Storage Data Protector and VERITAS NetBackup, have modified their licensing 
rules for virtual tape to license it on a raw per TB basis. 
What is becoming apparent in the data protection market is the way that different technologies—
virtual tape, disk-to-disk, standard tape—are being deployed according to the different data types 
and topologies they protect. Consider the example in Figure 2, which shows the typical data types 
that can benefit from the use of HP virtual tape technology.
