Dear All,

 

After a "specialized" company did our legato networker upgrade and install of 
our new taperobot we are not getting the desired speeds we would like to have

 

Any help and insight would be appreciated

 

This is the new setup of our backup

 

Legato Networker 7.4.4 running on 1 W2K3 SP2 server

4 dedicated storage nodes als W2K3 SP2

50 W2K3 or W2K servers

 

LTO4 Quantum I-scalar Taperobot

 

Now I am told that LTO 4 should at least make 80 to 100 mb / sec

If we try it with a bigasm file of 25 Gb it does get a score of above 100 mb/sec

 

The people at the company tell me that the problem mainly is that we have too 
much small files (ie profiles and homedirs with word. Excel and powerpoint 
files)

 

I cannot believe that we are the only company with about 500 users that use 
LTO4 as backup type 

 

Could someone please reply with some figures of their backup, and or have any 
real solution ?

 

met vriendelijke groeten, / With kind regards,
