Just before you’ll call me an UPS maniac – here’s one more review. My current choice for 1-3 box server setup – APC Smart-UPS 1000VA USB & Serial 230V is not really similar to the SC1000 reviewed by me earlier, as the latter has a somewhat simplified design internally and also the box itself is different (standalone/desktop vs standalone/RM). And the non-SC is a full-sine model, and has a richer LED display. Continue reading ‘APC Smart 1000 (SUA1000I) with NUT / Linux’

Datacenter rack layout hints


A couple of hints when fitting a 19-inch rack with network and server equipment. I have seen just too many badly fitted racks and messy cabling. Here some of my guidelines. Continue reading ‘Datacenter rack layout hints’

Hi! Here’s another UPS review 😉 I am not an UPS tester by profession, but this topic seems to be around me recently, caused by various opportunities. This time I am playing with APC Smart SC1000 tower/rack-mount unit, and it’s nut interoperation. Continue reading ‘UPS APC Smart SC1000 with NUT / Linux’

UPS Ever Duo II Pro with NUT / Linux – bad idea


A bugIn my previous post about that device I described UPS Ever Duo II Pro working with nut under Linux, along with variables it exports, battery charge and drain cycles and this UPS’ issues. This follow-up is why using this UPS for serious unattended production environment is not a good idea. Continue reading ‘UPS Ever Duo II Pro with NUT / Linux – bad idea’

UPS Ever Duo II Pro with NUT / Linux


Toshiba 4S nuclear reactorUnless you are running a “Home Edition” of a nuclear reactor by Toshiba you need an UPS for your systems. Here’s another tale about running an UPS with nut under Linux. This time it’s an Ever Duo II Pro [PL]. Full specs for Duo II Pro family are available on the manufacturer’s website – but only in Polish. Note that the non-Pro versions are specified with “no software included” and (as I have heard) are “dumb” UPS-es (again: unconfirmed). The Duo II Pro model is “smart” and reports real data instead of just states via contact-closure. Continue reading ‘UPS Ever Duo II Pro with NUT / Linux’

UPS Orvaldi 1000GE with NUT / Linux


Power linesI recently got an Orvaldi 1000GE (or 1000 GE) [PL] [EN-by-google] to test it. This model – in my area – is externally equipped with:

  • 2x Schuko (european) output sockets
  • 1x IEC 60320 C-13 (PC, female) output socket
  • non-detachable input cable with Schuko plug
  • 2x RJ-45 for some kind of protection for network I guess
  • 1x semi-RS-232/serial DB-9 female socket for control

First thing I did was to plug some load on the output (UPS testing classic: a lamp), connect it to charge, and turned it on. I also connected it to a Linux host with a red RS-232 cable (included in the package). And installed nut on Linux. Continue reading ‘UPS Orvaldi 1000GE with NUT / Linux’
