Re: scsi controller for external devices

[Francesco Pietra <frapietra@alice.it>]

thanks a lot for pointing out the bottleneck. is that bottleneck also when no 
external device is attached to the scsi controller? i intend to connect the 
scsi chain to the workstation only occasionally for scanning and backup to 
have access to data by an ordinary pc. normally the scsi chain is connected 
to the pc. 

if the scsi controller causes a bottleneck per se, what about accessing the 
scsi devices attached to the pc from the workstation through the zyxel adsl 
rooter?

i need that motherboard to get the best floating point for the money. with 
that workstation i am already at the lower limit to do ab inition quantum 
chemical calculations for large molecules. 

thank you again
