advice needed on first time build

[kraftwerk_autobahn]

Hello - former lurker here

 

I have a spare i7 6700k laying around along with a handful of SSDs.  I haven't decided on capacity, but maybe 2-4x 10TB drives with 6 SSDs as a r/w cache? Are there any caveats I should be concerned about? I think i've found all the right gear to do this on a z270 mother board, I'm under the impression i'll need to team a 4 port nic(I350T4V2) and a hba(9207-8i)to leverage everything. Is 10Gbps in the ballpark on something like this?

 

I also have a bunch of ancient 500GB hdds - are these even worth their power draw?

Does unraid even support 6 SSD as a read/write cache? Is there a drive limit even with pro license? I'm thinking in the realm of a 2-4TB SSD cache if possible.  Oh and what is trim support looking like? 

 

example SSD cache setup:

 

• 4x 500GB SSDs in raid 0 as a read cache
• 2x 1TB in raid 1 as a write cache

 

so i'd have a 1TB write cache, and a 2TB read cache?

 

it seems finding a reasonable case for something like this... doesn't exist either. 

any advice or input would be great!

 

thanks!

No such thing as a read cache in unRaid.  All reads will happen at the maximum speed of the drive on which the file is stored.
