Where I am the Supermicro 847E2C-R1K28JBO chassis (which includes two 1280W power supplies, and SAS backplanes and front+rear hot swap bays for 44 3.5-inch hard drives)  costs the same as 6.37 10TB enterprise (5-year warranty) hard drives.

 

That's 50TB of parity-protected data for your rendering needs.

 

I've never seen a chassis as large as the one you're after for sale in the used market (eBay or otherwise, yet -- I am sure I will one day!) so as far as I am concerned you're buying a new chassis at full price. I don't see how you're going to fit it into such a small budget.

 

Best forward-thinking logic is as already suggested: Spend money on larger drives so you can use cheaper, smaller chassis, like one of the ones you already have... unless you can barter a deal with a good metal bender in your area who can make you what you need.

 

 

Thank for the suggestion but that case dose not have the  PCI slots needed for the amount off card I have. It doesn't have to rackmount

Nobody is suggesting this. How did you come up with that number anyway?

 

There are some deals that have been posted on the forum recently for 8TB drives for $200 or less. One 8TB drive can replace 4 of your 2TB drives. 7 x 8TB could replace all 28 x 2TB. Then you would only have 7 drives to power, 7 drives to troubleshoot, 7 drives that might fail instead of 28.

 

In fact, you could convert one of your parity to data since you would only have 7 data disks, and just buy 6 x 8TB. And as mentioned, there is no need to do it all at once.

 

So, you could do the complete conversion for about 1.2K, and the expenses and troubles of finding cases and power supplies to support so many drives would be gone.

 

You mention using this system for graphics work. Did you know that unRAID doesn't stripe data? There is no performance benefit from multiple drives, since any file is read from only one drive.

I don't live in the USA It $400 for 6tb drives and $800-$1000 for 8tb where I from.Yes I away the drive aren't striped unraid act as a "data pool" system. I needed 40tb off space 6 mouth ago as I had sameone send me 6k raw footage from a red camera. And been using my server as a rendering server since free up my work station. I looking for psu and case  recommendations I got $1000 us to play with can go to $2000 if needed.

If I can find a 40-50 drive server when I upgrade in the next 1-2 years I be buying 2 tb ssd and put 40 ssd in the server and same pice ssd if cost affective. But for the time being the drivers are doing the job.

But there are some things in your posts that sound like you are possibly on the wrong track.

 

It might be cheaper in the long run to upgrade the disks. 2TB drives aren't very cost effective these days.

 

More drives mean more problems. You already have a problem powering them. More parts just means more things that can fail.

 

Larger drives are cheaper per TB and possibly faster due to data density.

 

Do you know the only reason to have a parity disk larger than any one of your data disks is so you can eventually replace the data disks with larger ones?

 

unRAID allows you to mix disk sizes as you want. There is no need to have all the disks the same size, or to replace all the 2TBs at once. And there is absolutely no reason to have a parity disk that is larger than any data disk you will ever use.

I understand your point but I don't want to spend 5k in buy new drivers if I can.The 8 tb drive was me testing them for the storage  server.This is my old storage server that's I add 10 hdd to and 10 ssd to.When the drivers die I look into upgrade the server to ssd and piec drives. As most off the parts are from 2012-2013.

Why not upgrade your 2TB drives to bigger ones? unRAID allows upgrade of individual disks at your own pace...

 

This is my rending server there no need for more then 60tb off space on this server. My  Storage server is 200tb with 6tb drivers. This is getting off topic a little. The server in question renders video most days that way there the titans and 50 core  with CPUs power

The maximum number of data disks in the array is 28, plus 1 or 2 parity disks.

 

Yes I will understand of the inerwork off unraid hdd limit's I have 2x 8tb parity disk and 28 2tb data drive and 10 ssd that 40 drive now I work in the film industry I use a lot off data

Hi Unraid forum 

I looking for advice on where I can get a server case that supports 40+ drivers 50 would be good. And a psu that can power the drivers plus 2 titan gpus and 2 power hungry CPUs. I have seen the 45 drives 60 bays server but that cost 10k for me and that a complete server.I have all the cuts just need that case and psu. Right now I using 2 1000w corsair psu and 2 cut up 24 server case. It look bad need a more better way off managing the case's. And no I not split the system up and it renders video on the servers.
