Quick question how did you get so into this i want to get my first job because my first idea of starting my own in our metal shop is not going to work right now because my grandparents had a big fite and my grandpa is staying there and he moved his cars out there and i cannot risk hitting them. Before you ask why i need this server is because we are still making files they are smaller 10-20gb but we all have drives full of ideas there are about 6 of us all with varying drive sizes this has been in the works for almost 2.5 years now.

You sound quite young, and to be honest, I doubt that this server will get made. BUT with that said, most people get into this by doing it as a job first. It's rare (but does occasionally happen) that home lab guys will set up a petabyte style server. It's just not needed for the vast majority of people. The cost of drives alone are out of reach for most people. 45 drives is extremely overkill.

 

Some quick math. Let's say you use 8tb drives. Put 6 of them in a double parity raid setup and you will have roughly (very rough estimate) 32 tb of space. That will gave you 1600 of your 20gb projects.

 

Be honest. Do you see yourself making 1600 projects in the next 5 years? That is close to one project a day without having a weekend or holiday.

 

I chose 5 years because I arbitrarily decided that is how long it will take for 8tb drives to EOL

the budget is no problem i have $4000 and i want to see how good i have gotten but i need this much storage because my friends cannot hand external hard drives to each other and we have almost 80-90 tb of stuff that we want to backup and be able to access everyone files and i am only 14 s i am young for this stuff and we are awlase working on files and my friends want to make a game to test out there skills i just make 3d models and keep/make everything sorry for the spelling mistakes if there are any i am tired i was at my local social distancing concert

i would share the files here but the only ones i currently have on my computer are weapons/school projects and my main computer the power supply is bad so tomorrow i may go and get one.

That will get you 16 drives at most per card. Hope you have many Pci-e slots... 

That's a bit false.

You can use SAS expanders, and you usually can have like 240 drives per card, with enough expanders.

Yea, i meant direct attached. I mis-spoke. I am still skeptical that this will ever see the light of day however.

From description:

Seller Notes:	“-Pulled from working server. This is a SAS/SATA expander, it is NOT a RAID card. You will need a RAID/HBA card already installed in your system for it to work. When used with a compatible card, it will add an additional 24 to 28 SATA or SAS devices. This card will work at 6Gbps with full duplex SAS drives for 3 Gbps half duplex SATA drives.”

oh sorry you can have descriptions on eBay

Yup that should work just fine., its an OEM version of a LSI 9211-8i (SAS 2008 Chipset). You might want to also check out the 9210-8i/9211-8i (theyre the same card just different packaging).

thank you the part picking is not my specialty i used to just buy whatever someone said i needed but i have been working on being less of an impulse buyer actually i would have bought 2 or 3 of those cards without double checking this forum over the last few weeks has probably saved me $200 us

[the gamer that is bad]

thank you

to be honest my friends and i can produce that much with all of our for fun projects but only about 10% of them see the light of day sorry for the late response  

[the gamer that is bad]

we nomaly do 1 a day

[the gamer that is bad]

i have started the test print because i do not need to worry about cost or time on the case and i will test the system with some of my old drives i would not trust with my data
