Hi,
Would it be possible to get some clarification on what would work
and not for the 10Gb Intel network cards?
I compare the man page, both man(4) ixgb and man(4) ix as well as
the hardware section and looked at the data from Intel to find more
in trying to answer that question.
But I am still looking for confirmation of the support or not in
OpenBSD for some of them. I get conflicting information and I am not
sure what is real.
The hardware compatible page do list:
# Intel 82597 PRO/10GbE based PCI adapters (ixgb)
# Intel 82598 PRO/10GbE based PCI adapters (ix)
The man(4) ixgb show the 82597, fine.
The man(4) ix does list the 82598AF, 82598EB, 82598AT and 82599EB as
well and the X520 series SFP models, X520,DA2, X520-SR1, X520-SR2,
X520-LR1 but not the RJ-45 model X520-T1 based on the same 82599ES.
But again the man(4) ix do not list the 82599ES as a supported
chipset, but that's what is in the X520 SFP series.
The intel product documents are confused about which chips they
use. The clearest split is something along the lines of:
7 82599EB -- PCI Express* (PCIe*) 2.0, dual port 10 Gigabit
Ethernet controller
7 82599ES -- Serial 10 GbE backplane interface for blade
implementations (includes the 82599EB SKU functionality plus serial).
Well the document may be confused, but then, what am I suppose to used
then? I used the documentation I can find and read it to find the
answer. If that's also wrong, how am I suppose to find out then?
I will go look for more technical specs sheet then, but still I would
love to know the answer for sure if anyone actually know that first
hand. I am confuse, the man page appear to be confuse, the Intel
documentation is cnfuse based on what you say too. So, everyone is
confuse. So, some clarification would be welcome.
Looking more at Intel to try to figure this out here:
http://download.intel.com/network/connectivity/products/prodbrf/252454.pdf
I see all the listed model in the man page X520-DA2, X520-SR1,
X520-SR2, X520-LR1 are all based on the 82599ES, but then the
82599ES is not listed in the chipset in that man page, however these
cards works based on the man page and then the X520-T2 is also based
on the same chip 82599ES as well. So, it should work right and
should be in the list or am I missing something?
What about the Intel 10 Gigabits AT2 then. It's designed with the
82598EB and that's on the man page, but not listed in hardware,
anyone knows if that works or not?
Based on the man page, the X520-T1 may be wouldn't work, but looking
at what chip it used and what other model are supported it should
also work. I would appreciate confirmation or denial here and
possibly an update to the man page to clarify that?
Anyone have one of these and can tell for sure if that's true or not?
So, shouldn't the 82599ES be added to the man page if the X520
series are all supported then?
And possibly the X520-T1 as well as it does use the same chipset,
but only the difference in the connector or am I missing something
here?
I would appreciated some feedback either way as spending $600+ to
find out if it doesn't is a bit hard. (;>
There are mentions of 82598 10GbaseT working, I don't see why
82599 10GbaseT wouldn't work off hand.
That could well be, but I learn many years ago to do my homework first
on hardware support with OpenBSD and even if that may well be possible,
it doesn't make it so however. It's a bit pricey to find out if yes or
no that would work, so that's why I asked first if someone n the know
might have one first here.
The analogies is the same, they have 82574 working, so why not the 82576
right? But it is not working as well and hardware wanted was fro the
82576 as well as for the 82580. The 82580 was taken care of a few weeks
ago based on feedback on misc@.
Anyway, thanks for your feedback, I appreciate it, but I would fell more
comfortable to be in the know I must say and I am not.
Best and thanks for your time.
Best,
Daniel
