Benchmarked example: Improved backup performance in 
multi-server SAN/LAN environment 

 

Figure 8. Example showing how virtual tape improves backup windows and single file restore times 

 

 
Figure 8 shows five servers. Servers 1 and 2 have network connections to the backup server, while 
Servers 3, 4, and 5 have SAN-attached storage residing on the HP StorageWorks Modular Smart 
Array 1000 (MSA1000). The configuration simulates a small mixed (LAN and SAN) backup 
environment. Approximately 2.6 GB of known data (file sizes 64 K to 64 MB, 2:1 compressible data) 
is created on Servers 1 and 2 (on the local drive) and on Servers 3, 4, and 5 as mapped LUNs on the 
MSA1000 disk array. 

The five servers are backed up to three different configurations: 

•  A physical tape library with two physical LTO-2 drives—the HP StorageWorks MSL6030 
•  A five-drive virtual tape library with no compression on the virtual tape drives 
•  A five-drive virtual tape library with compression on the virtual tape drives 

A total of approximately 13 GB is backed up and the time is measured as reported by the backup 
application from start to final completion message.
