Is PCI-X downward compatible with PCI ?
Yes. PCI-X cards will fit in 3.3V PCI slots, though (of course), they're
restricted to the PCI bandwidth (33Mhz/32-bit). They won't work in the
5V PCI slots, but I'm 99.999% sure that the SB2500 uses the 3.3V PCI
slots (as the 5V ones were obsoleted in the early 2000s).
Further research on PCI - PCI-X compatibility resulted in the following statement.
"[u]If it fits in the slot, it should work[/u]"
Yup. They did the physical design keying Right. :-)
You need to get a SAS one instead. Pretty much any of the LSI models are
my favorite - the LSI 1068 is cheap and available from various OEMs
(including Sun).
What is the Sun part number ?
External-only HBA:
Option SG-XPCI8SAS-E-Z, or mfg part 375-3488
Internal-only HBA:
mfg part 370-7696 (this is hard to find, as it's not available as an
Option)
You do need to make sure that the card has the OpenBoot PROM code
loaded in its firmware, NOT the PC BIOS version. Specifically, look at the
card and make sure the seller's docs explicitly say SPARC Solaris,
not just Solaris.
I was planning on booting off of the internal UltraSCSI disk. Is OpenBoot PROM
code required if you are not going to boot off of the device ?
Yup, you still need OpenBoot info just to be recognized as an available
device.
