  • I put it all under a spoiler tag because it’s a lot. Let me know if you’re interested!

    inventory/specs

    UPS

    Eaton 5SC 1000 full sine-wave inverter

    Rack

    13U enclosed rack w/casters and magnetic front door

    Networking

    TP-Link EAP225 Wifi AP

    Aruba Networks S2500-24P-US Switch

    • 24 Port Gigabit Switch
    • PoE
    • 4x SFP+ 10Gbit ports

    Servers

    Dell R720xd

    Components

    • 2x Intel Xeon E5-2667 v2 @ 3.3GHz (8-core CPUs)
    • 14x 8GB Samsung ECC 2Rx4 Dual Rank DDR3 10600R 1333MHz RAM (112 GB)
    • Intel 4P X520 NIC (2x SFP+ 10Gbit, 2x 1Gbit)
    • 2x 750W PSU
    • IDSDM 6YFN5 dual SD module
      • 2x Sandisk 16GB UHS-1 Extreme SDHC SD cards
    • PERC H710P Mini Host Bus Adapter
    • PERC H310 Host Bus Adapter
    • Dual 2.5" Hotswap Drive Backplane 0JDG3
      • 2x Crucial MX500 500GB SSD
      • 2x 2.5" Dell Hotswap Drive Caddies/Trays
    • Front Hotswap HDD Backplane
      • 12x HGST Ultrastar KP06 6TB 7200RPM HDDs
      • 12x 3.5" Dell Hotswap Drive Caddies/Trays
    • Rack Rails (They hold the server in place, but they’re missing some bearings. If the server is pulled out on the rails it may not go back. Replacing these should be less than $50)
    • Locking front panel
    • iDRAC Module

    Notes

    • Runs ~235W at idle
    • Can handle many VMs and multiple simultaneous 4k Plex transcodes
    • This is basically the best set of parts for the xx20 series Dell servers and is more capable than a lot of the xx30 units

    Dell R710

    Components

    • Rack Rails
    • Locking front panel
    • CD Drive to 2.5" Drive Adapter
      • Samsung 860 Evo 250GB SSD

    • Dell 0KJYDB 2xSFP+ 10Gbit NIC

    Notes

    • Set up to be an ideal backup server
    • Just add hard drives and it will be ready to go
    • iDRAC modules are available on eBay if you would like out of band management





  • Do you have separate 2.4GHz and 5GHz SSIDs? If not, you should try that. 80mbps to 5mbps through 4 sheets of drywall is a pretty steep drop for 2.4GHz, and 80mbps is a pretty low throughput for 5GHz AC1300, which your APs support. Are both APs wired? Try disconnecting one and doing speed/signal strength testing in all rooms, then do the same with the other AP in its location. If there is a huge difference, try switching the AP locations. Also, it may be worth checking whether the APs are negotiating a gigabit wired connection to your switch/router.






  • Uh, no it’s not LOL. Not even a little.

    I believe their point here was that your claim that “open source” is self explanatory is wrong. You’ve imprinted your definition onto it and called it “common sense” without thinking further about how how nebulous it is without extra context. This is then driven home by your lack of understanding on the AA discussion.
