Hi Raion and Weblacky,

or in case of O350 you can do some wire hacking and run the SAS/SATA lines into your drive bay, which is what I have done for expansion chassis in Numalink'ed configuration:



Using some simple Molex Y extension power cable and SATA dual power cable with the existing cable and no soldering:



Here is how it turned out in the chassis:



I pulled 2 x SAS/SATA lines through as I wanted to still have option of using the existing SCSI back plane for a single 3.5 inch disk and wiring lets you get power to DVD-ROM

So it you can have: Boot Disk, 1 or 2 SATA SSD and the DVD-ROM all in a single chassis.

EDIT: To get benefits of PCIX I moved LSI board up into top slot and removed USB card (in picture). I had falsely assumed that IO9 was PCIX as it uses full slot width. But checking via L1 “pci” shows that it runs as 66MHz PCI, while having LSI in top slot on its own , it runs as 100MHz PCIX.

This was way easier than mucking around with Dallas DS1742W chips ;-)

Cheers from Oz,

John.
