I am thinking to build a 10TB NAS - Need help!

Hi I am thinking to build my first DIY NAS capable to do the stuffs below. I am thinking to run FreeNas. I have picked the parts in pc part picker. Regarding to the ECC ram, is it necessary for this kind of system? It will be great to hear feedback from others! Thanks in advance 🙂

 

Requirement 

  • Minimum 10TB of storage 
  • Capable to host 2 Linux VMs (Running docker in VMs)
  • 10GB NIC - high speed transfer
  • 32GB RAM (ECC or non-ECC??)
  • Compact form factor - (I opt for mini-itx form factor)
  • Low power consumption ( My UPS has a low power rating)

Question

  1. Is ECC unbuffered memory a must for a NAS?
  2. Gold rated PSU is it good enough for this kind of application?

ECC memory in a FreeNAS/TrueNAS CORE system is not a requirement, but it's nice to have in situations where the data is very important. I personally don't use it - my NAS is a Dell OptiPlex 755 from 2008, and it's been going fine on a mismatched set of DDR2 modules for several years now, and I've yet to lose any data.

Generally RAM performance is not the top priority in a NAS, so the extra safety of ECC is good.

 

Gold rated is generally more than enough, assuming the PSU is decent.

Exactly as others said, not required, but I chose to use it… I spent close to 2 grand on all the hardware including 10x4 TB drives, what’s an extra ~100 bucks in RAM to get ECC.

 

Also, if you want to run VM’s, I would look at virtualizing freenas as running things under freenas is not ideal. I use ESXi and run a few Ubuntu server VM’s alongside Freenas, and a windows VM as well. I used to try and run things under freenas, but that was just a headache.

why exactly do you want to run docker in a VM when you could choose a NAS OS that can run docker natively.
