So you don’t work in the enterprise… what does that mean? Well, for one, it means that Liebert (Emerson) isn’t likely going to come out and help you architect a power-solution for your customer’s new “server-closet”. Now, they’ll do a bang-up job if you’re putting together a new datacenter, but for 1 – 5 servers? They’re probably overkill.
Beyond that, I’ll tell you what it doesn’t mean. And I almost can’t believe I have to post something like this; but it doesn’t mean that you can ignore scheduling servers to shutdown gracefully in the event of a power-outage. Those UPS devices that you have connected to your customer’s servers do more than protect against power-events like brownouts. Like 99% of them are smart, they’ll detect a power-outage, look at the power-usage, and determine a good time to send a shutdown signal to your servers.
Those of you working in a medium, or enterprise environment take this for granted. I do too when I’m doing integration work for an enterprise customer - it's just a given. But I can’t tell you how often I’ll visit a potential client on the SMB side of the business, only to find that the previous IT group responsible for their servers neglected to install the software/agents for managing power-outages.
What, you have multiple servers connected to 1 UPS?
Software agents get installed on the servers that don’t have the hardwired (USB, serial) connection (You can even buy add-on cards that let you hardwire multiple servers to one UPS). When a power-outage happens, the UPS talks to the hard-wired server, who then sends shutdown signals to the agents running on the other “clients”.
It’s that simple. Don’t risk your customer relationships, or data corruption on something like this.
