flavors: Arbel memfree (Device ID 25218) and Arbel in Tavor mode (Device ID
25208, with local attached memory). For the OS the 25208 looks identical to
the Tavor (Device ID 23108, PCI-X card) this may explain why you see in
/proc/infiniband/core/ca1/info "Tavor" while you actually have a PCIe
card.</FONT></FONT></SPAN></DIV>

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>
<BLOCKQUOTE type="cite"><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?
</PRE></BLOCKQUOTE><PRE wrap=""><!---->
Yes, if your Windows box is the same, it should work.

<BLOCKQUOTE type="cite"><PRE wrap="">This is likely a novice question, but
what do "Tavor" and "Arbel" refer to? The different chipsets?
</PRE></BLOCKQUOTE><PRE wrap=""><!---->
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.
