We have been seeing 169GB per hour with the SAN based Storage Pools on the SAN 
to the 3592 drives SAN attached in a (Fabricated Mode).  The HBA's are only 
1GB, we may see higher throughput.  We let the tape drive handle compression.  
We are seeing our Intel based data @ about a 1.5 to 3.0 Comp ration (400/500GB 
per cart) we are seeing our Unix / Oracle Data averaging 3:1 to 8:1 (900 - 
2,100GB) Not kidding...

Subject: What are the fastest migration times seen using 3592 drives ?


Can anyone share a number (such as a GB/hr figure) from personal experience
for migration process rates using 3592 tape drives ?

at native 40 MB/sec, that is 144,000 MB/hr or 140 GB/hr and I'd expect to
see about 70% of that, or 98 GB/hr for a migration process (of data already
compressed by the client)

just wondering what the real world has to say...
