    no it's not, class 4 is 30W, class 8 is 90W, see here for example https://www.skyworksinc.com/-/media/SkyWorks/SL/documents/public/white-papers/understanding-the-ieee-8023bt-poe-standard.pdf or Power over Ethernet - Wikipedia

    2U Short JBOD Disk shelf - SAS3

    NOT going to work. In this system, the PSUs plug directly into the motherboard. There is no way to power the backplane, as there is no PDB (Power Distribution Backplane) that has ATX power as in other chassis.

    Intel E810: Available breakout modes

    Power Consumption of ConnectX-6 and E810-CQDA2 is roughly the same (ConnectX-6 need 2.5W more) No module lockout on Ethernet (it's a bit different for Infiniband), just some oddities (like the NIC refuses to run 100G transceivers at 40G if they don't have the Mellanox OUI coded) CX623106A is...

    Intel E810: Available breakout modes

    Nope, you'll be able to get 100G (see report here https://fast.dpdk.org/doc/perf/DPDK_23_03_Intel_NIC_performance_report.pdf - Dual Port NIC with only one port connected, but clearly > 50G throughput possible) You need to differentiate between two things: Maximum Total Available Bandwidth for...

    e810-CQDA2 woes.

    What does Kernel Log / dmesg say? I think I remember from my cards that EPCT only worked with the proprietary driver.

    Mellanox Switches - Tips & Tricks

    Yes it will work. However single stream throughput will be limited to 10Gbit/s due to the way link aggregation works. Total throughout can reach 40Gbit/s but only if you have multiple streams (different source/dest mac or ip or port)

    Mellanox Switches - Tips & Tricks

    1. looks like normal Mellanox, not Dell OEM 2. yes, upgrade to 3.6.8012 and enter the license license install LK2-EFM_SX-5L11-5M11-5K11-5T11-5U11-5G22-05J2-205N-2205-P220-88A2-L5T5-3MYW-9 Then put switch into right mode / system profile (e.g L3 single or whatever it’s called) 3. yes, but it‘s...

    Mellanox Switches - Tips & Tricks

    Nobody who needs such a switch should use a WebUI anyway... (Ignoring Netbox with declarative management that automatically deploys to switches - but that's still not a UI for the switch)

    Yes this is known. Onyx has already been in LTS mode sind some time without major updates.

    Mellanox Switches - Tips & Tricks

    Hu??? They are already on ONYX. There is nothing to convert ONIE is essentially just a boot manager that allows a switch to support different OSes more easily. Onyx uses ONIE
