Hi all. Has anyone tested the Mellanox SX-1024 series of switches with
ROACH-2 and 10 and/or 40 gb NICs?
These switches have 48 10 Gbe ports and 12 40 Gbe ports on them.
Thanks!
John
hi john,
jack hickish tested a mellanox SX1012
(12x40Gbe, or 48x10Gbe, or mixture),
when he was visiting berkeley.
the SX1012 worked beautifully on roach2, after jack upgraded
the switch firmware. and it's a great price. ($6K)
i think jason has also tested this switch.
best wishes,
dan

Yeah, we're looking at a 1024, or a 1036. They all use the
Hi John,
As Dan said I've tested (to some extent) the SX1012. I just used one

turned data through 8 x 10GbE ports. It worked well basically up to
line rate, with no CRC errors after a few hours of operation, but only

Hi John,

I have eyed the SX1035 and SX1036

understanding of the difference?

The SX1012 and SX1036 definitely use the same ASIC series and both suffer from
the PHY link problem. I've got seven of them here, and tested them with 20
different ROACH-2 boards. As Jack points out, some links are worse than others
and swapping cables and ROACH2 mezzanine cards often sorts the
hi jason,
thanks for all this info.
in the leda correlator,
the 10/40Gbe links are unidirectional,
roach2--switch and switch--gpuserver
so i don't think leda would encounter the
switch--roach2 bit errors,
although it wouldn't hurt to upgrade the firmware.
best wishes,

Not to steer this conversation too far off track, but does a patch
exist to enable the ethernet CRC check within the 10Gb yellow block?
When I tested the switch I used Dave MacMahon's CRC generator block,
but it would be nice if there was the option to have the 10 gig core
use the UDP crc -- or

I can't see any, really. The sx1035 has slightly lower latency, and is
way more expensive...
I don't really understand what L2 Lite Switching is,
