NVIDIA MCX753436MS-HEA SmartNIC Firmware 28.39.3560-LTS

Firmware which is added at the time of manufacturing, is used to run user programs on the device and can be thought of as the software that allows hardware to run. Embedded firmware is used to control the functions of various hardware devices and systems, much like a computer’s operating system (OS) controls the function of software applications. Firmware may be written into read-only memory (ROM), erasable programmable read-only memory (EPROM) or flash memory.

The ConnectX-7 smart host channel adapter (HCA) provides up to four ports of connectivity and 400Gb/s of throughput, hardware-accelerated networking, storage, security, and manageability services at data center scale for cloud, telecommunications, AI, and enterprise workloads. ConnectX-7 empowers agile and high-performance networking solutions with features such as Accelerated Switching and Packet Processing (ASAP2), advanced RoCE, GPUDirect Storage, and in-line hardware acceleration for Transport Layer Security (TLS), IP Security (IPsec), and MAC Security (MACsec) encryption and decryption. ConnectX-7 enables organizations to meet their current and future networking needs in both high-bandwidth and high-density environments.

The ConnectX-7 smart host channel adapter (HCA), featuring the NVIDIA Quantum-2 InfiniBand architecture, provides the highest networking performance available to take on the world’s most challenging workloads. ConnectX-7 provides ultra-low latency, 400Gb/s throughput, and innovative NVIDIA In-Network Computing acceleration engines to provide additional acceleration to deliver the scalability and feature-rich technology needed for supercomputers, artificial intelligence, and hyperscale cloud data centers.

Bug Fixes:

- Fixed a misconfiguration in OVS when RTTs are sent on a different priority that affected Congestion Control algorithm. This happened when the Round Trip Time (RTT) Congestion Control internal packets did not reach SW, even when flow is software offload (and the packets were not moved yet to the hardware offload by the OVS). To solve the issue, now such packets are sent to the SW when they are SW offloaded.
- Fixed an issue that caused Completion Timeout to mistakenly be treated as Advisory Non-Fatal error. Now Completion Timeout is treated as uncorrectable error.
- Fixed an issue that prevented PLDM command Get Schema URI from functioning properly when there were no base RDE resource IDs.
- Fixed an issue that prevented RDE Port resource from showing 400Gb speed in CapableLinkSpeedGbps and in MaxSpeedGbps in some InfiniBand cards.
- Fixed an issue where the CR_SPACE was open to any read operation, even though some reads could lock the gateway. Bad reads from CR_SPACE will now result in a bad_access error being returned.
- Blocked access to invalid CR-SPACE registers when the adapter cards are secured.
- Fixed an issue that resulted in device assert when using DCBX CEE.
- Improved ZTR_RTTCC algorithm fairness when running with 4K MTU.
- Fixed an issue that caused CNP or RTT counters to not wrap-around properly.
- Fixed an issue where Congestion Control could malfunction due to an invalid database.
- Fixed an issue that resulted in CNP moderation's mlxconfig preventing the CC mechanism from working properly.

About Network Adapter Firmware:

When connected, the operating system usually installs a generic firmware that helps the computer to recognize the newly attached device.

However, proper software must be applied if you want to make use of all features that the network adapter has available. This task also allows computers to properly recognize all device characteristics such as manufacturer, chipset, technology, and others.

Updating the adapter's firmware and utilities version might improve overall performance and stability, increase transfer speeds, fix different compatibility problems and several network-related errors, as well as bring various other changes.

To install this release, simply get the package, extract it if necessary, run the setup, and follow the instructions displayed on-screen. When done, don't forget to perform a system restart and reconnect the network adapter to make sure that all changes take effect properly.

Without further ado, if you intend to apply this version, click the download button and install the package. Moreover, check with our website as often as possible so that you don't miss a single new release.
