Looks like I may need a bit more clarification... given:<br>
<br>
-bash-3.00# cat /proc/infiniband/core/ca1/info <br>
name: InfiniHost0<br>
provider: tavor<br>
node GUID: 0005:ad00:0002:6732<br>
ports: 2<br>
vendor ID: 0x2c9<br>
device ID: 0x6278<br>
HW revision: 0xa0<br>
FW revision: 0x400060000<br>
PCIe width: x8<br>
-bash-3.00# <br>
<br>
Wouldn't that imply that tavor is a PCIe chipset as well?<br>
thx-<br>

Tavor is the MT23108 chipset (PCI-X), Arbel is a PCIe chipset which
comes in two flavors:
MT25208 - Arbel in Tavor mode (fully compatible with MT23108, has local
attached memory connected to the chipset).
MT25218 - Work without local attached memory (mem free), from SW
perspective looks different from Tavor mode therefore requires modified
driver.

Bring up the computer management console (right-click my computer,
manage), then select Device Manager.
Find the HCA (probably PCI Device under Other category), right-click,
properties.
You should see a "Details" tab, select it, and select Device ID or
Hardware ID.
The drivers should work with:
PCI\VEN_15B3&DEV_5A44&SUBSYS_5A4415B3&REV_A1
PCI\VEN_15B3&DEV_6278&SUBSYS_627815B3&REV_A0
The first is a MT23108 board, the second is a MT25208.
Let me know what your device is reported as (select the hardware ID,
then ctrl-c as the right-click menu doesn't give the option to copy) if
it isn't one of the above.

<pre wrap=""> However, on a
linux box pulled from the same batch, lspci yields:
02:0b.0 PCI bridge: Mellanox Technologies MT23108 PCI Bridge (rev a1)
03:00.0 InfiniBand: Mellanox Technologies MT23108 InfiniHost (rev a1)
I'm not 100% until I open the box of course, but in this particular
case I am 99.9% sure the windows box is using the same card. It
doesn't find anything when I point it to the HCA directory. But
you're saying that should work w/ the 23108, right?

Yes, if your Windows box is the same, it should work.

<pre wrap="">This is likely a novice question, but
what do "Tavor" and "Arbel" refer to? The different chipsets?

Correct - Tavor is the PCI-X HCA chip from Mellanox, found on the
MT23108 HCAs. Arbel is the PCI-Express HCA chip, for HCAs with memory,
found on the MT23208. Someone form Mellanox will hopefully correct me
if I've bungled this up.
If your system is PCI-X, you have an MT23108.
