I'm curious, does a 3 minutes power down to replace a RAM stick is that much of a deal in enterprise server that they need to invented a whole new technology just for that?

The hangup is that you think shutting down and restarting a server takes 3 minutes

[–] kaboom36@ani.social 3 points 4 months ago

The surplus enterprise hardware I have in my homelab takes 3 minutes to just get to BIOS

[–] Oha@lemmy.ohaa.xyz 16 points 4 months ago

yeah.

The coveted 5 9s of availability is only 5.26 minutes of downtime

5.26 minutes per year*

[–] frezik@midwest.social 12 points 4 months ago (1 children)

Yes. Server boot times are long. Enterprise level NICs and hard drive controllers do a lot of checking at startup.

Historically, there were Sun servers that could hot swap CPUs. X86 can't do that, though.

Many that weren't based on x86 microcompters could do this: Tandem, I mean, Compaq, I mean HP NonStop machines, Sun Ultra Enterprise as you mentioned, IBM s390 and System-Z, several HPUX systems, I'm sure there's others.

First of all, yeah. In enterprise, 1000 transactions per second can be a requirement. Second, enterprise servers take longer to spool up than 3 minutes.

[–] rainynight65@feddit.de 4 points 4 months ago

Depending on your SLA, 3 minutes can be a pretty big chunk of your monthly error budget.

Have you ever power cycled a server? It can take over 10 minutes depending on the machine.
