| Mellanox SX1012 |
12x 40GbE (48x 10GbE with QSFP->4xSFP+ breakout cables) |
Tested ROACH2 (sfp) -> ROACH2 (sfp) |
yes (see comments) |
ASIC firmware 9.2.7322 |
The SX1012 is a half-width 1U switch, retailing in the US at ~$6000. Testing was with a single ROACH2, corner-turning packets over 8x 10GbE connections. Initially the ROACH was losing many frames on RX, but this appears to be fixed with a switch firmware upgrade to 9.2.7322, at least when using Mellanox cables (tested with MC2609130-003 3m copper QSFP -> SFP cables). Some RX errors remained when using unbranded cables. No packet loss or bit errors detected in use at near line-rate for a couple of hours. |
