| NVIDIA Network Engineer at Snetsystems | 2.5 | I've found NVIDIA Cumulus Linux highly effective for EVPN VXLAN in data centers, but it's complex, costly, and unstable outside that use case, with limited support from NVIDIA Korea and configuration challenges compared to other vendors. |
NVIDIA Cumulus Linux is designed for data center networks, so switches running this software cannot be used in other network areas such as campus environments. NVIDIA Cumulus Linux can only be used in a data center.
NVIDIA Cumulus Linux version 5.12 is supported.
My most recent project was a Superpod project where I deployed both InfiniBand switches and NVIDIA Cumulus Linux switches.
NVIDIA Cumulus Linux supports the EVPN VXLAN protocol in data center operations.
Regarding support for EVPN and VXLAN tunneling, EVPN tunneling uses Type 5 with MPLS label, which I believe is sufficient. NVIDIA Cumulus Linux has excellent support for EVPN VXLAN.
In my opinion, NVIDIA Cumulus Linux can primarily be used for EVPN and VXLAN.
Regarding areas where NVIDIA Cumulus Linux could be improved or enhanced, all areas have issues when EVPN and VXLAN are not used. NVIDIA Cumulus Linux has a significant problem in that with any other routing protocol, if you modify the configuration, you need to reset the daemon, which affects the service multiple times.
I started working with NVIDIA Cumulus Linux just over three months ago.
NVIDIA Cumulus Linux is a very stable solution for EVPN and VXLAN, but if you use it for any other purpose, it is not sufficient.
I usually communicate with the technical support of NVIDIA. I have found that NVIDIA's global technical support is very useful in supporting us, but NVIDIA Korea's support is not useful. A few days ago, when we opened a case with NVIDIA Korea, they provided only public information. Our customer wanted more detailed information, but NVIDIA Korea did not provide it. I gave the score for NVIDIA Global an eight, but I gave the score for NVIDIA Korea a three.
Positive
I usually participate in the initial setup of NVIDIA Cumulus Linux.
The usual setup process for me is that NVIDIA Cumulus Linux configuration commands are very complex, more complex than any other network vendors. The Juniper CLI is very similar to NVIDIA Cumulus Linux, but NVIDIA Cumulus Linux is more complex than Juniper. The CLI configuration and commands are very complex. Other network vendors' commands are very simple and direct, so when viewing the configuration, it is clear what it is for. However, NVIDIA Cumulus Linux has very complex configuration, so when viewing the configuration, it is unclear what the configuration is for.
There is enough documentation, guides, and manuals for the installation process. NVIDIA provides sufficient information for NVIDIA Cumulus Linux, but this is not standard.
I am a consultant for NVIDIA Cumulus Linux.
In my opinion about the pricing of NVIDIA Cumulus Linux, it is too expensive for its function. It is not worth the money.
For NVIDIA Cumulus Linux, InfiniBand is a very good switch for low latency, but NVIDIA Cumulus Linux is a very unusual switch compared to other network vendors.
Regarding the automation features of NVIDIA Cumulus Linux, they are not easy to use. I need more time because I have not thoroughly considered this feature.
I have experience with automation capabilities. During our project, we needed our device's configuration. When we were working on the project at Coupang, our device's configuration was for NVIDIA, so we only configured the management IP.
I gave this review a rating of five.
