Hi all,
 so I have two unraid servers, the main has an i5 with 8gig of memory and the backup has an AMD A10-6800K  with 8gigs of memory. The primary server has a Supermicro AOC-SAS2LP-MV8 card . I am awaiting a new Norco 4220 4u Chassis as my current case is maxed out (15 drives in total).
So my question is, if I move the hardware from the backup server and use the drives from the primary server and then use the primary server USB drive to boot from, will the system work without other updates needed? OR should I just bite the bullet and do all the upgrade to the primary server.
My reasoning is that I would have a lot less downtime from moving  to the new case by only having to move the drives and then booting  it with the hardware from the backup server. 
Is there any concerns with AMD and Supermicro AOC-SAS2LP-MV8  ?

Also, for 20 drives, what would the minimum psu requirement?
Thoughts?

A minority of users have problems with the AOC-SAS2LP-MV8 when IOMMU is enabled in the BIOS.  Myself I have zero issues (running an A8-6600K and an A88X-PRO mb)

Ball park is ~2A per drive on the 12V line, (plus CPU / MB requirements, etc) (And ~ 1A per fan that comes with the case (ratings would be on the fan)

 

Get a single rail PS that has at least 56A on the 12V line.

Only if you run VMs with hardware passthrough will you have any problems...

So I am hoping the present PSU which is running 15 drives will work for the 20 drives, it is a Corsair HX750.

I only use dockers for Sickbeard, SABnzb and Plex, no VMs.
