Re: SCSI HBA: PCI or PCI-e

I've a system which uses the:

motherboard. I need to add SCSI to it. The one 64-bit 66MHz PCI (3.3V)
slot is busy (with an 8 port SATA card). So I need a SCSI HBA that works
under Linux and fits in either:

* PCI-e slot
* 32-bit 33MHz PCI (5V) slot

I was all set to buy a nice LSI, but it uses PCI-X.

The LSI 20160 (single channel U160) is 32-bit PCI. Note that 32-bit 33MHz PCI tops out at 132 MB/sec, so even a single U160 SCSI channel is enough to flood the PCI bus (presuming, of course, that the SCSI devices themselves can sustain that rate). You're unlikely to find U320 SCSI or multi-channel U160 SCSI cards for 32-bit PCI for that reason.

If you prefer Adaptec, their 19160 card would also be a good fit.

As far as Linux support is concerned, nearly any Adaptec or LSI Logic card should work with Linux. Drivers for a wide variety of their cards are included with the standard kernel.
