You're right, it's not that much for 2U. But for this config, I think they'd probably go for the 1400W power supplies:
- 16 x 25W SSDs
- 2 x 225W CPUs
- On top of that, add RAM, cooling, etc.
Honestly, it's still manageable. I doubt they'd put 10 of those in a single rack (you'd need an ISP that would want serve 2.2M subscribers in peak from a single location, not necessarily desirable on their side); but if the site is getting full, you'd feel the (power) pressure (slowly) mounting.
- kkielhofner 4y agoI didn't dig into the CPU config, etc but you're right they'd probably go for the 1400W power supplies which is 5.4 amps max at 208V. It's for an older config (based on the other specs) but the current Netflix OpenConnect docs call for 750w[0] which is more reasonable even for this hardware configuration because no one really wants to consistently run their power supplies at 80% (even in branch loss) for obvious reasons. They absolutely wouldn't want to concentrate them. The entire purpose is to reduce ISP network load and get as close to the customer eyeballs as possible. I don't have any experience with these but I imagine ISPs would install them at their peering "hubs" in major cities - in my experience the usual suspects like Chicago, NYC, Miami, etc. [0] - https://openconnect.zendesk.com/hc/en-us/articles/360034538352 https://openconnect.zendesk.com/hc/en-us/articles/3600345383...
