#300tb — Public Fediverse posts

@vermaden

Thank you for this valuable insight from the powerful BSD POV
This would make hosting for pure personal LAN use fairly affordable and with fairly low HDD power requirements, since you use 30TB 27.28 TiB HDD at a lower HDD count

Do you have a link to these 27.28 TiB drives because I haven't seen them yet

Take the time to analyse this post on Anna's Archive

They teach you in meticulous detail why they took the time to create mirror backups of this musical archive which is torrented in bulk at 300 TiB

It may look like I was joking but making such a backup is technically simple.

300TiB / 24TiB per HDD is 12.5 drives

300TiB / 16TiB is 18.75 drives

In reality it's more complex.
A 16TiB HDD is not 16TiB but 16TB lineair

Given a typical 4TB HDD I get just 3.64TiB in partitoned EXT4 HDD Space
That is 91% of the 4TB HDD

At 16TB that is 14.56 TiB {yes the loss is enormous and those hard drive companies are idiots because computer systems count in base² Binary not base10}

A 16TB drive is actually a 14.56 TiB Drive, it should be sold as 14.56 TiB not 16TB because that is misleading and false advertisement.

With these parameters we will need in reality 300 TiB / 14.56 TiB = 20.6
So we will need 21 drives for the task at 14.56 TiB. In the replication you will need twice the amount

This would become a JBOD just a bundle of drives, which is the easiest form to concatenate hard drive space to together.

A 4U JBOD enclosure can harbour a lot of drives. At the most you will need two.

Double the amount if you want a local backup of your main Spotify data.

Then you will need a 1U case for the computing System. A typical server motherboard, 1x AMD EPYC CPU, 512GB ram is more than sufficient.

You will need Fast Access to the Drive Array. 10GBit / sec in duplo should be enough. That means that your switches cables and network infrastructure will be expensive.

The high cost of AC power globally, can be a limiting factor when you have to power 42 hard drives provided that you are a Soho Network Builder, though.

That is the only factor you cannot calculate with constants
