RAID 5 SCSI drive data retrieval - good drives - failed hardware

I have an old DELL SERVER POWEREDGE 2500. I have 5 drives (SCSI) in a RAID 5 configuration. The controller died and I really just want to get a copy of some files off this server. How can get 5 working drives data off these hard drives? (without paying an arm and leg?)

Look at RAID Reconstructor https://www.runtime.org/raid.htm

Free to try.  If it can identify your RAID and the drives pay the money.  You'll probably need a SCSI card suitable for the drives to try it out.

I would try and get a used controller, you're sure it died? What are the symptoms?

Why do you need to access those disks? If the data was of any importance I'm sure you have backups, and then the logical procedure would be to just restore from your backups.

You can buy a replacement controller on eBay for $20 that is much less than cost of the recovery software

What if I a not sure if its a controller? I can access controller but
I think the boot partition is corrupt. The drives looked good but it no boot device found on reboot.

I was hoping I buy some UBS plug into drives and a software package and I can suddenly see the data.

The runtime software is free to try, but you will need a JBOD controller to talk to those drives.  Since you have to buy a controller anyway, why not buy the kind you need.  No boot device is consistent with a controller failure, or a catastrophic multiple HDD failure that kills the RAID5.  

You're going to have to either reconstruct using another controller onto an external scratch drive, which could take well over a day AFTER you buy a controller appropriate for JBOD use, or just spend about the same amount of money and get a replacement controller that may just work.

If you don't have a SCSI JBOD controller then you can't do any diagnostic work beyond making sure the HDDs are plugged in and are getting power and signal.   (Make sure the boot path is set in the BIOS also incase that got reset, which is rare unless the battery on motherboard is ancient and lost settings)

The battery on the board is ancient. What is a JBOD controller? And does it come USB................. That really is my dream.

Plug in the bundle of drives into the Just A Bunch of Drive box and plug USB and then run that software - done. I get a single folder off drives.

A JBOD controller is a NON-RAID controller.  THere is no such thing as a USB->SCSI adapter.  You need a SCSI adapter.  Adaptec 29160 is an example.  Since these terms are unfamiliar, I STRONGLY recommend getting a replacement controller with same make/model you have now.    I also don't recommend trying to do a recovery with software.  This is non-trivial with a learning curve and you run risk of making things much worse.

Never connect RAID5 drives though USB, data is spread over the disks. This is something you could only try in a RAID1 situation.

Can you get into the BIOS of the controller and check the set? If you can do that then the controller could be OK.
