    Cheapest, quietest, lowest power 40Gbe switch? (and preferably less than 55cm deep)

    Cisco 3064PQ you can mod for new fans and will be totally silent, but It has only 4 QSFP+ ports and 48 SFP+. if I remember correctly 65W

    2x 56GbE Optimization, slow ceph recovery, and MLNX-OS S.O.S.

    I didn't max the 100GbE yet, but what I think is: Connectx-3 40/56 (PCIE 3.0 x8) LACP can do about 7000MB/s in real life when copy files on NVME raid or single NVME PCIE 4.0 Connectx-3 40/56 (PCIE 3.0 x8) no LACP 4420MB/s over single ethernet port at 40G Connectx-4 (PCIE 3.0 x16) can do...

    Celestica Seastone DX010 - not working in 100GbE with Mellanox ConnectX-4, need help?

    This is my sonic version, issues that I know are: *No auto-negotiation (hardware is supporting it but OS not) *Huge delay in status of the connected transceivers

    Celestica Seastone DX010 - not working in 100GbE with Mellanox ConnectX-4, need help?

    I have an unexpected problem with Celestica DX010, I just (few days ago) start the new company network and realized that I don't have link with 100GbE cards at 100GbE speed, 40GbE is working fine (with Mellanox ConnectX-4 100GbE and Mellanox ConnectX-3 40GbE cards), but 100 isn't. Autoneg is not...

    Brocade / QLogic 1860 - Worth it?

    Mellanox ConnectX-2 are good too (for example MNPH29C-XTR) ConnectX-3 like MCX312A-XCBT are better but for me it's mostly about shorter connector and Gen3 PCIE not Gen2 (all works fine under windows and linux). Also this one works, but I remember some firmware or drivers issues...

    Wi-Fi 6E Router (performance/price) ?

    Real-life scenario ~220MB/s achieved. On 2 antena setup, I don't have 4 antena WiFi-6E card yet. HW: Xiaomi AX6000 WiFi 6E Intel AX210 6E Pros: -price ($115 LOL) -only one "6E router" that you can buy now? Cons: -Chinese (good thing is it's not Huawei, less red guys involved there) -Not...

    Celestica Seastone DX010 - SONiC in L2 mode, need your help

    Yes it will be always 4 same lanes for each port - just dont want to fix them on QSFP+ or QSFP28. I don't have any SFP28 cards :) (some 10GbE SFP+ I can connect via Cisco modded 3064PQ or Cisco 3164Q connected via 80GbE LACP)

    Celestica Seastone DX010 - SONiC in L2 mode, need your help

    Thank you, generated much nicer and cleaner file that we were able to edit based on the original one :) Do you know if it is possible to turn on autonegotiation on (most of the cards I am using are ConntectX 3 40GbE, I have few ConntectX 4 100GbE) it should be supported by platform, but seems...

    Tested: DL580G8 (Gen8) and G9 (Gen9) *Lack of* Compatibility

    Yes, where XX is close to 99 : There is single core speed factor that is taken into equation :) But small sub result's should be ~4x faster. True. single core it's still faster than E5 2678 v3 (on DDR3or even DDR4) and still about 65% of the fastest intel CPU after many years :) For sure we...

    Tested: DL580G8 (Gen8) and G9 (Gen9) *Lack of* Compatibility

    UnrealEngine: we have no precisely measuring it unfortunately, it's about 2 times faster than 5950x (with linking - where 5950x is much faster):/ In my opinion Passmark10 is good at it (Passmark9 was not good) BTW. I found the old photo of single CPU installed in DL580 G8 - E7 8895 v2, but...

    So the compatibility things about DDR memory are shifted to the "Jordan Creek" and "Jordan Creek 2" chips ?

    Tested: DL580G8 (Gen8) and G9 (Gen9) *Lack of* Compatibility

    promised benchmark: *It's not the fastest one because single core performance it's only stable if 1 CPU is inside (and then it's even faster :) I thnk about 2100 points ) You can compare in details to: 5950X: https://www.cpubenchmark.net/cpu.php?cpu=AMD+Ryzen+9+5950X&id=3862 after putting...

    Haswell-EP <- I can say from experience that just some of them support DDR3 one of them is: E5-2678 v3 and I am fully confirmed that it support is while others (for example 1660 v3) not, and I am almost sure that this is LCC/microcode thing not a BIOS(UEFI). Problem with E5-2678 v3 is that it's...
