  • I’ve bought some brand called MightyMax on the rainforest site for replacement UPS batteries They work good. My friend who works IT swears by them to recondition old APC Schneider units.

    Generally cheap sealed AGM lead acids are a lot safer than cheap lithium, the chemistry is simpler, harder to fuck up and the internal safeties are mechanical, not BMS based. Thry may have slightly lower capacity than a name brand cell but for emergency backup when home labbing it won’t matter.















  • I’ve never ran into issues either, but generally in any situation where data integrity is somewhat important, ECC is a very good idea. Its never a problem until suddenly it is.

    I don’t give a crap about my Minecraft server having ECC, but a storage server where cached data gets written to disk, I’d rather have ECC ensure nothing gets corrupted.


  • ABSOLUTELY ECC memory, 32gb or higher if you can afford it these days as TrueNAS does benefit from a decent cache space, especially with so many drives to spread data slices across.

    Realistically unless you expect multiple concurrent users, any 4 core or higher CPU from 2015-on will be plenty of power to manage the array. No need for dedicated server hardware unless the price is right

    I have a Dell PowerEdge t3 SOHO/small business server tower that I gutted and turned into a 5x8tb config. It only has a middling 4 core Xeon 1225v5 and I never get above 50% CPU usage when maxing the drives out. More CPU is needed if you’re doing filesystem compression or need multiple concurrent users.


  • I believe you’re right but don’t know enough about the real back end magic to confirm. I want to say I once read that the DM was always broadcast to all servers but that seems pointless.
    What matters is that dm’s are not private and should not be considered private, both in transit (during sending) and at rest (copy sitting at each server)
