1.2 Supported Cables and Modules
Please refer to the LinkX® Cables and Transceivers web page (http://www.mellanox.com/products/interconnect/cables-configurator.php) for the list of supported cables.
1.2.1 Switch and HCAs Cable Connectivity Matrix
Mellanox Quantum™ based switches and ConnectX®-6 HCAs support HDR (PAM4, 50Gb/s per lane) and EDR (NRZ, 25Gb/s per lane) technologies.
As the ConnectX adapter cards are identified by their maximum supported throughput (e.g. ConnectX-6 VPI 100Gb/s card can support either 2-lanes of 50Gb/s or 4-lanes of 25Gb/s), the exact connectivity will be determined by the cable that is being used.
As a reference:
| Speed Mode | Speed Supported | Number of Lanes Used |
| HDR | 200Gb/s InfiniBand | 4 lanes of 50Gb/s |
| HDR100 | 100Gb/s InfiniBand | 2 lanes of 50Gb/s |
| EDR | 100Gb/s InfiniBand | 4 lanes of 25Gb/s |

Firmware Changes and New Feature History
Table 22 - Firmware Changes and New Feature History (Sheet 1 of 2)
| Feature/Change | Rev. 20.25.7020 | Description |
| Physical Layer Retransmission (PLR) | Added support to the Physical Layer Retransmission (PLR) functionality for HDR speed. | |
| Link Speed | Link-up time improvements. The link up time is up to 60 sec | |
| Bug Fixes | See Section 4, "Bug Fixes History", on page 25 | |
| Software Managed Steering Tables | Rev. 20.25.6000 | Added support for creating software managed steering tables in eSwitch/FDB. |
| Bug Fixes | See Section 4, "Bug Fixes History", on page 25 | |
| General | Rev. 20.25.2006 | HDR speed rate is at GA level. |
| Zero-Touch-RoCE Counters | Zero-Touch-RoCE counters are now available to the user for debuggability purposes when using the Zero-Touch-RoCE feature. | |
| Bug Fixes | See Section 4, "Bug Fixes History", on page 25 | |
| General | Rev. 20.25.1500 [Beta] | This is the initial firmware version of Mellanox ConnectX-6 adapter cards at the following speed rates and development stages: When using it as InfiniBand, at HDR speed rate, HDR is at Beta level When using it as Ethernet, at 100GbE speed rate, 100GbE works only in 'Force mode'. 100GbE is at Alpha level |
| Immediate Responder Not Ready (RNR) | The switch sends an RNR with T =0x1 when a limited packet is dropped. This might occur after a specific timer to prevent retransmission due to no response or when the buffer is released. Immediate Responder Not Ready (RNR) enables the hardware to re-send the packet immediately, to allow the senders to sync. |
|
| VSC Security | VSC security includes the mechanisms which will prevent a reasonable host from affecting other hosts from using VSC. | |
| Extended Responder Not Ready (RNR) | Enabled Responder Not Ready (RNR) configuration. Now the number of RNRs can be set higher than 6 and lower than indefinite. | |
| ODP support for SRQ & XRC | Added support for send opcode operations targeting a SRQ/RMP with the receive WQEs using ODP memory. In case the receive WQE receives an ODP, the device will generate ODP notifications (EQE) and PFAULT will abort CQEs. Note: It is recommended to prefetch the memory used by the receive WQEs to reduce ODP occurrence as these have significant latencies and will cause a performance degradation. |
|
| Auto-Sensing when using 25/10GbE Optical Modules | This new capability accelerates the network to auto-sense the port speed and use it when using a 25/10GbE optical module. Meaning, if the used module is 25GbE but the port is a 10GbE port, the speed used for that network will be 10GbE. | |
| mlxconfig | Renamed the BOOT_RETRY_CNT1 parameter to BOOT_RETRY_CNT. |
Table 22 - Firmware Changes and New Feature History (Sheet 2 of 2)
| Feature/Change | Description |
| Reduced Firmware Upgrade Time | Reduced firmware upgrade time using mlxfwreset tool to ~3 seconds. Using this capability requires enabling PARTIAL_RESET_EN in mlxconfig and using MFT version 4.12.0 and up. The "PARTIAL" refers to not resetting the port modules (which is not mandatory for firmware upgrades). Note: Currently this capability only supports firmware upgrade and downgrades to firmware versions newer than XX.25.1020. |
