    Downgrade 40Gb/s connectivity to 10Gb/s without changing network card and fiber cable.

    If i understand, i could use (to the switch side) https://www.fs.com/fr/products/61713.html Number of fibers : 12 Connector A : Male UPC 0.35dB Connector B : LC Uniboot Polarity : Type A But before, i would check if i can negociate my Connect-X 3 to only 10Gb/s using a single pair of fibers...

    Downgrade 40Gb/s connectivity to 10Gb/s without changing network card and fiber cable.

    Hi, I would done a temporary transition from 40Gb/s to 10Gb/s for one link on my home network. It's because, i have plan to change 2 switches in my home lab but not in the same time (for budget cost distribution). For a while, i will not have anymore 40 Gb/s connectivity. I have 4 links to 40...

    QSFP28 100G to differents speeds like 40Gb

    Hi, Thanks, I didn't see the S8550-6Q2C. If it had 8x QSFP28, it would be a good option. In FS.com, my attention was also for the S5850-24XMG for the RJ45 : Switch Ethernet L3 à 24 Ports, 24x 10GBASE-T/Multi-Gigabit et 2x QSFP28 100Gb, Support MLAG, S5850-24XMG - FS France A bit power hungry...

    Basement Relay Switches

    Will it be mostly silent ? I have (on the servers room) theses ones: Quanta LB4M Gnodal GS4008 Mellanox SX6036 None of theses can be used on living rooms because they do to much noise... How much noise do brocade ones ?

    How bad can your SMART numbers be on a used HD before you refuse it?

    So from my perspective I'm really aware from the "Elements in grown defect list" A no-zero value is a no go for me. In your case it's OK. For the high corrected ECC read values, i would perform such things like badblocks (write+read) and rerun a long smartctl to see how theses values...
