    just finish with an ESXi low wattage home server build
    details here: https://forums.servethehome.com/index.php?threads/my-new-low-wattage-homelab-esxi-build.22551


    I am think at maybe build another server like this as i have case, fans, psu, ssd and so on, so i am just missing the mainboard, cpu, ram.

    so i thinking at doing the same board X11SSZ-TLN4F but with a I7-7700T instedt of the I5-7600T

    Main specs.
    Has to fit into ATX case
    Low power, like TDP at 35w or there around
    64gb ram
    min. 4x SATA connector
    BMC/IPMI - ikvm for headless
    OS will be ESXi
    min. 2x 10gbit nic
    like to have 2 other 1 or 10gbit nic, but not an requerment
    silents is important, low heat/fan and/or passive
    Keep cost down

    Some say the X10SDV-TP8F but that seems to run me up in cost do to EEC ram and maybe not as low watt


    So what suggestions do you guys have another build. ?????

    You won’t get silent with a build like that
    I wouldn’t think. It would be very hard anyway, the 10G NIC’s need cooling even if you can get a good passive CPU cooler.

    If you don’t have the NIC already at hand I would still be tempted by the Xeon-D you also for some reason also need very high clock speeds just because it’s all one package you know just works with ESX.

    Well the older and lower TDP D-1541 boards sometimes can be had cheap.
    The newer D-2100 boards are pricy and built more for performance than super low power.

    Is a 4-cord D-1521 good enough ? Or the new D-2123 boards ?

    Are you only after 2 x 10G or is more connections preference ? Fair fee options, rang in price from $400-$1000 in 4,6,8 core options

    Seems that the d1521 and 7700t is close
    http://www.cpu-world.com/Compare/345/Intel_Core_i7_i7-7700T_vs_Intel_Xeon_D_D-1521.html

    D-1521
    *older - nov. 2015
    *more tdp
    *lower clock
    *less cache
    *cheaper
    *fixed in board

    I7-7700T
    *newer - jan. 2017
    *lower tdp
    *higher clock
    *more cache
    *expensive
    *socket - can better reuse board with bigger cpu later

    other then the cost, it seems that the i7 is better at lower tdp, more cache, higer clock per core, is newer cpu(and boards) , better reuse option.
    so for me it is looking like that i7 is the better option here even that it cost more.

    >Are you only after 2 x 10G or is more connections preference ?
    i use one 10g for storages (nfs) and one for VM.
    some times i use an extra 1g for vm there is more isolated from the others and i better like the nic option then using the vlan... but it is not a most have and i can always just put in add-on nic

    2015 or 2017 doesn’t really matter it’s all 14nm for intel, the ++ process or the latest ones trade some power consumption (yes increasing) for some clock speed.
    Don’t forget some tdp is for the 10g parts on the Xeon D cpu.

    If I was me I wound be be looking at the simplicity of d-1521 board but since having other systems that use rdimm that also makes more sense personally.

    I guess only you can decide now.

    yes at the moment i think that X11SSZ-TLN4F + I7-7700T will be what is likely the best for me.
    +it is board is the same
    +cpu can be changed, so easyer reuse later
    +low tdp
    +newer board and cpu
    +guess newer pcie specs
    +normal ddr4 ram
    -more expansive

    d-1521
    ++cheaper
    -have to hunt for used boards
    -use rdimm over normal ddr4 (seen fron an price and reuse point)
    -higher tdp
    -see posts in forum about high heat and neaded better cooling.


    So at the moment it is more in the I7 direction then the xeon
