Hi Jack (and John),
Interesting report. Difficult to puzzle out
differences in our mutual experience unless the
1012 is unlike the 1024 in subtle ways.
We (LEDA) did not require an upgrade or Mellanox cables
for the 10/40GbE links. Again - I would look
forward to discussion people may have with Jonathon
(Cc me if not conducted via the Casper list).
Best,
Lincoln

Hi John,
As Dan said I've tested (to some extent) the SX1012. I just used one
ROACH2 and corner
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
after
- Jason put me in touch with some Mellanox guys who provided updated firmware
- using branded Mellanox 3m QSFP -> 4xSFP cables
Before the upgrade transmissions from the switch to the ROACH2 would
frequently fail.
Of course this may or may not be remotely relevant for the SX1024 :)
Good luck!

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

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
