Thoughts on running a large array on a SOC

[oliver]

I have a large array, 22 drives totaling 164TB with 2 parity and a 1TB cache.  I'm using an HBA card with 4 ports as well as a maxed out SAS expander. 

 

Software wise, this array is used for archiving, very little activity.  I write data to it once and it's barely ever read back or used.  No VM's or docker containers.

 

I've been contemplating swapping out my aging mini-itx motherboard for an ODROID-H3+.

It's tiny, low energy, has 2.5GB ethernet.  Now, how do I get my drives onto it?  Well, it has:

1 x M.2 slot (PCIe 3.0 x 4, supports NGFF-2280 cards)

 

A m.2 -> pciex adapter like this:

The SAS expander doesn't need to be connected to the motherboard, it only needs power + connection to SAS card.

 

I think the main question im left with is will this setup work with so many drives and how much of a performance hit are we talking?  Given im either reading or writing to the drive only one at a time and at a very low rate, do you think this is doable?  Probably the only problem I can think of is a parity check which will probably take a lot longer but I can live with that.

 @jit-010101 wasn't particularly happy with those, according to this post:
