never underestimate the bandwidth of a van full of hard drives
Reminds me of AWS Snowmobile, which is literally a shipping container filled with harddrives.
I’m somewhat surprised to learn that each Snowmobile unit is only about 100PB in a 45x8x9.6ft highwall shipping container
Gonna ballpark in stupid units to see how wrong my intuition that that’s not very dense is:
Assuming dense but not hot new thing spinning rust, 16TB per 34.5 cubic inch standard 3.5" disc.
(100PB/16TB)*2 (assume at least two spindle redundant) is about 12,000 discs, so about 414,000 cubic inches of just discs without any of the supporting equipment.
A highwall shipping container is like 5,900,000 cubic inches, so only like 7% of that thing would be discs.
Or, accommodating a little bit of the support, let’s say it’s just full of those commodity 90-bay 4U storage servers. Those are 19" x 7" x 26.4" (3511.2 cubic inches) for 1440 raw TB each, again 2 spindle redundancy so you’d need about 140 of the things for 100PB, round up to 500,000 cubic inches of those… still less than 9%.
Yeah, unless I did my math radically wrong, that’s surprisingly not very dense.
Yeah, it really sounds a bit low. I’m not sure what else goes into these containers. I assume there might also be a bunch of portable equipment and cabling that goes into moving the data in and out of the container? Power infrastructure and cooling and what probably takes up quite a bit of space as well.
Id assume rhey put in some standard racks on shock absorbers and more redundancy than usual,
And wired all that up to acentral input.Its probably not build to minmax the capacity,
but to fit the largest usecases.
reminds me of factotrio’s cars on belts…
We have 1 TB microSDs. A pigeon could probably carry at least 100. If I did my math right(which i probably didn’t), if it takes 24 hours of travel that’s still a 8Gb/s connection.
How would that work when birds aren’t even real??
Since they are government drones, they might as well ship USBs everywhere they go
Bird’s don’t eat worms, they charge off secret buried worm-textured USB cables.
That’s why it’s important to encrypt your data in coconuts before utilizing avian carriers
Isn’t this what Twitter is doing? /s
Never underestimate the bandwidth of a semi truck full of SD cards.
I also like the Definitions of RFC2324 - https://www.rfc-editor.org/rfc/rfc2324
This document describes HTCPCP, a protocol for controlling, monitoring, and diagnosing coffee pots.
