OK, but SAS (Serial attached SCSI) is technology in the area of storage interface 
technology where all big storage vendors see future (e.g. they give up: 
FC and SATA drives, SATA drives are replaced by MDL SATA drives (SATA 
7200RPM drives with SAS interface)).

Therefore I don't understand why distros are giving up SAS which is 
also SCSI (of course old legacy SCSI is understandable).

And legacy SCSI is of course technology from yesterday but e.g. LSI53C895A 
has largest OS support ever as far as I know (from DOS, Win95, NT4, W2K, 
XP, Vista, Windows 7, Linux, etc.). Also CPU usage is low.

What's your preferred storage technology on QEMU?
Where do you see future?

BTW: The underlying problem I want to solve: I want to migrate a VMWare 
Server 2.x VM based on Buslogic SCSI controller to QEMU/KVM. And
geometry translation to IDE/SATA doesn't boot up the system ... Any ideas 
to migrate to other storage technology (VM is offline)?

Ciao,
Gerhard
