The UIO slot itself is proprietary, but provides pinout interfaces
to support both PCIe 1x, 4x, and 8x, as well as PCI (32-bit and
64-bit), and PCI-X (presumably 100 and 133MHz). But ultimately it
depends on what board offers what pinouts through the UIO slot.
Rather than "document it", here's how it works in the Real World(tm):
- We need a PCIe x8 on our X7SBi for a low-profile RAID card
- X7SBi motherboard has a UIO slot:
http://www.supermicro.com/products/motherboard/Xeon3000/3210/X7SBA.cfm
- UIO slot on this board supports one of the following, depending
on which riser you buy:
- (1) PCIe x8
- (1) PCI-X 133MHz (64-bit).
- Scroll down to the bottom of the page and you'll find:
- CSE-RR1U-ELi -- 1U PCI-E x8 Riser Card for X7SBi
- Visit Supermicro's Accessories page, and select Riser Cards:
http://www.supermicro.com/support/resources/Riser/riser.aspx
- Search for CSE-RR1U-ELi, and you find:
http://www.supermicro.com/a_images/products/Accessories/CSE-RR1U-ELi.jpg
- Contact Supermicro distributor (whoever you got the server from, or
you can contact Supermicro directly to help find a distributor for
you) and get the CSE-RR1U-ELi. Some online retailers do sell these
risers too.
- Costs about US$11.
- Buy it, install it, mount the card in it, enjoy.
By the way, I'll add that the AOC-USASLP-L8i is **not** compatible with
the UIO riser/adapter for the X7SBi. This should be apparent just from
examining the location of the PCIe x8 slot on the RAID card vs. where
the CSE-RR1U-ELi PCIe x8 slot is located.
You'll find what boards the AOC-USASLP-L8i is compatible with, UIO
riser-wise, here:
http://www.supermicro.com/products/accessories/addon/AOC-USASLP-L8i.cfm
So in general, make sure whatever Supermicro card (RAID, Ethernet, SAS,
SCSI, whatever) you're going with is indeed compatible with whatever
Supermicro board you stick it in.
Best thing to do is contact Supermicro Technical Support and ask. Their
TS folks are better than average; I can get full specifications for ICs
out of them, while I've never been able to achieve this with Tyan.
Rackable (who uses Tyan mainboards) might have better luck. :-)
Thanks for the info. I have no doubt a Supermicro HBA will work in a
Supermicro motherboard and chassis given the correct Supermicro risers
or other accessories.
What I was questioning was where the OP said: "it fits into a standard
PCIe slot and works nicely there as far as I can tell" - which to me
sounds like you could use this HBA in a *NON-Supermicro* motherboard.
I was just wondering if that was truly the case, given how in the photos
it looks to be arranged physically backwards from a regular PCIe card,
and given how you mention "The UIO slot itself is proprietary".
But some more digging on Google has turned up a few mentions along the
lines of:
"""
This card plugs into a normal PCIe 8x slot but the
metal mounting bracket bolted to the card is made
for a UIO slot (which is why it's so cheap).
All you have to do is remove the metal bracket and
zip-tie the card to your case for mechanical support.
Electrically it'll work fine in a PCIe x8 or x16 slot.
"""
If someone wanted to make PCIe compatible brackets for this affordable
card, they'd probably sell a fair number to small shops or home users.
