I'm picking a brand for a service offering HaaS. And am hoping I can find a brand that has central management.
All the modern enterprise ones will support network management, but the thing to keep in mind is a UPS is essentially an insurance policy - you've got to keep up with the premiums (maintenance, replacing the batteries as they age out, testing, ...) if you want to be able to trust that they'll work on the one day a year that you need them.
Related anecdote - I know of a company that spent several million dollars installing a backup diesel generator in their secondary DC. Several years later, a new CIO came in and decided that they should actually be practicing the DR plans that they had in place, and one of those plans involved shifting all their load off DC A onto DC B, then switching DC A onto backup power for half an hour or so. Test day came and they managed to switch the load over with minimal issues, then they switched the power over to backup and... nothing. UPS batteries were several years out of life and lasted less than a minute, and the generator failed to start because it had never been maintained - turns out fuel goes bad if you leave it sitting in a tank in the sun for years, and trying to start a large engine with no lubricant really messes stuff up. Cost them mid-6-figures to get the generator torn down and rebuilt - manufacturer laughed them out of the room when they tried to claim warranty. Don't know if they tried to start the generator at the primary DC, but I suspect some bricks were shat thinking about how far in breach of contract they could be with some of their clients
Yep even mid range ones did so way back in the early 90s. It was a common fairly cheap feature that used rs232 mostly. In those days non unix systems did not care as much if powered down without warning. So us early (me 1996) Linux users really found it useful to have the ups initiate shutdown before it died. Windows users of the time only tended to worry if they had the PC running when not sat their. Few had internet at home in the early 90s and those that did were dil up. So for many it was not worth the cost when you could just turn off the PC if a power cut was long term.
Now with most people using laptops for casual use. I really cant imagin anyone buying one without the feature.
Their PowerPanel Personal and Business editions both seem to work with all of their UPS models. I used to run PowerPanel Business on a basic tower-style model.
I was happy with my cyber powers for years, but then the batteries died (official replacement batteries, after 3 years - the originals lasted 5) and the ups just stopped even passing power through. This is someone's old blog about this https://blog.networkprofile.org/...
I have good expreience with APC and Legrand. Small chinese noname brands are a hit or miss, but mostly miss.

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Was unaware UPSes even talked to the computers they power, thought they were just backup batteries
