[tech] molmol SSD storage upgrades (plus RAM)

[Nick Bannon]

- UCC has been running with two main fileservers in recent years
  (motsugo and https://wiki.ucc.asn.au/Molmol )
- molmol is full, there's been some cleanups but we need to buy some
  new, larger drives
- at least some of that is urgent to avoid major disk-full disruption
- we should notice that we're on the other end of the
  https://goldenrod.bikeshed.com/ dilemma this time:
  - having convinced ourselves that "making do" and that some of the
    cheaper options won't cut the mustard, we're bringing the molmol
    standard up to new, with warranty, business class "NAS" SSDs
  - but... sticking with 2.5" SATA for now? vs M.2/U.2/E1.L/PCIe ?
  - I think these are 6x Seagate Ironwolf Pro 125 ZA3840NX10001 3.84TB SATA SSD's?
  - do we have a firm link to a supplier?
  - approximately AUD $1069 each, plus $131.39 for shipping insurance
  - notably, they do claim to have Power Loss Data Protection, we have
    only a couple of other drives in this/enterprise class (donated)

- molmol is still a "decent" server, so we're starting from the idea of
  upgrades rather than full replacement; it currently has
  - 16x front-facing 2.5" 1TB SATA drives
    - mostly WD Red spinning rust WDC WD10JFCX-68N (da0 to da14)
    - one replacement Crucial CT1000MX500SSD1 SSD (da15)
  - 3x? internal 2.5" SATA SSDs for boot and cache
