There are actually 3 different PCI card edge connectors types for each BUS
width:
1) 5V (only)
2) 3.3V (only)
3) universal (supports either 5V or 3.3V depending on PCI connector type
on motherboard)
The Supermicro 370DL3/DLE motherboards have two 3.3V 64 bit PCI
connectors, but the Tekram DC-390/U3x controllers seem to use a 5V
connector. This doesn't fit.
This is not due to the SYM53C1010 chip that supports both 3.3V and 5V and
thus allows all the 3 types of PCI card connectors (5V, 3.3V and
universal).
The SYM53C1010-based boards from Symbios/LSI use universal PCI connectors,
but they are probably more expensive than Tekram ones.
- SYM22915 -> 2 Ultra3 (LVD) SCSI buses
- SYM21940 -> 1 Ultra3 (LVD) SCSI bus + 1 UltraWide SCSI bus
Thanks to their universal PCI connectors these ones works with both 5V and
3.3V 64 bit PCI connectors on motherboard.
Gérard.
PS1: In my opinion, Tekram choice for the DC-390 U3 PCI board connector
couldn't be worse, based on technical considerations.
