Plot twist: they’re 256MB drives from 2002 and total… 61.44GB. Still impressive, nvm. If they were the largest available currently (36TB) they’d total 8.64PB
that array is a POS. Changing failed drives in that would be a major pain in the ass… and the way it doesn’t disapate heat, those drives probably failed pretty regularly.
JBODS like those are actually pretty common in data centers though and are popular with cold storage configs that don’t keep drives spun up unless needed.
For the cooling, they usually use the pressure gradient between what’re called cold and hot aisles to force air through the server racks. The pressure also tends to be strong enough that passive cooling can be used and any fans on the hardware would be more used to just direct the airflow.
If you’re paying per U of rack space for colocation then maximizing the storage density is going to be a bigger priority than ease of maintenance, especially since there should be multiple layers of redundancy involved here.
you still have to replace failed drives, this design is poor.
I work in a datacenter that has many drive arrays, my main storage space direct array has 900TB with redundancy. I have been pulling old arrays out and even some of the older ones are better then this if they have front loading drives cages.
there is no airflow gaps in that thing… I bet the heat it generates is massive
Can’t make out the size of the drives but they’re HDD and there’s 240 of them.
Multiply that by what size HDD’s are available in the year you think this video was taken. Money is on 1 or 2 tb? Those are bulky as fuck though so they could be as little as 100 something GB, but then I think we’d be looking at a lot more piss-yellow plastic

They probably wait for like 20%of the drives in an array to fail before taking it offline and swapping them all out.
Also, this doesn’t sound like the architects problem, sounds like the techs problem 🤷
I work in a datacenter as the system admin and waiting after one drive fails for a second to fail is asking for disaster
The interface is SATA, not EIDE or SCSI, so I’m going to guess 2TB minimum but I’d bet they are more than likely 8TB drives.
Probably SAS but yeah
looks like SAS to me
You’re right - I found the source. Turns out they’re 8TB SAS, for a total of 1.92PB.
I guessed they were SATA. If that is the case, here is one such 36TB SATA HDD. Apparently Seagate make these in SAS models as well
This is a helluva range, do any wizards have a best guess at how much total disk space we’re looking at here?

1,920TB
That’s such an unfathomable about of storage – I’m an old man with 0.2 TB total on my backup of everything Also redlib link for the privacy enjoyers: https://redlib.perennialte.ch/r/computers/comments/od03lz/ever_wondered_what_2_peta_bytes_looks_like/
Hey, that’s a perfectly normal amount of storage. My personal files backup for my partner and I amount to about that much.
No shade in yo direction at all–I’m just amazed how much memory we can cram in handhelds much less these U-racks or whatever they called
Right? They have 2TB stuffed in MicroSDs now! That much storage in something the size of a fingertip
