  • As a splunk architect- I really enjoy it.

    For home use, its ok. But, without the enterprise features, it limits a lot of the capabilities.

    You CAN use cribl.io with it, to replace a lot of the missing features… and to reduce the amount of data being stored. It has an extremely generous 1T/day free plan.

    You can also use the universal forwarders, as they do not have a license attached.

    Data is only licensed when it is written by an indexer.

    There, are also ways of using the enterprise plan… by selectively not storing certain files under /etc… and restarting the container every few days.














  • Well, I use micro-inverters on my panels… which converts their DC, into AC on the panel itself.

    The microinverters are around 98/99% efficient, and actually PRODUCE more energy than they use- by allowing each panel to produce its maximum capacity, regardless of if one of the panels is randomly shaded.

    And- overall, the efficiency gains has been easily quantifiable, especially during the winter when one of my panels is partially shaded by the power riser.

    That being said.

    If you really want to avoid the inefficiency- and you use 48v battery banks, connect your server to those. But- not to the panels DC.





  • As somebody who has spent a ton of time messing with both 10/40/100GBe…

    My advice-

    1. use Intel or Mellonax NICs when possible.
    2. 10GBase-T (RJ45 / Copper) runs REALLY hot, uses ~9 watts, and the modules are expensive. Use Fiber / DAC / AOC / Twinax when possible. Its cheaper, cooler, more efficient.
    3. Mikrotik switches are fine. Nothing fancy, but, they work. I have one in my 10G network.
    4. Cat6 is perfectly fine for 10G, I have 60 foot runs of it through my house.
    5. Make sure flow-control is enabled on your switches / NICs. Can make drastic differences.

    I PERSONALLY use a unifi aggregation switch as my layer 2 10G switch. With 6 of the 8 ports filled, it only draws around 8 watts of energy, and is completely silent. This- is quite fantastic.

    I also use a Unifi PRO switch, for 10G routing, which is also silent, and pretty efficient.

    Granted, these are a lot more expensive then mikrotik switches. Mikrotik can handle the job just fine.

    If noise/power isn’t a concern, pick up a brocade icx6610-48-p on ebay. The absolute beef-daddy of switches, for 100$. 16x 10G SFP+, 2x40G QSFP, 48x1G poe.
