Hey there,
I'm currently building my first nas. I have a supermicro x9SCL-F mainboard with an Xeon CPU and 32 gb ecc ram (max what the mainboard supports).
As a case I have a SC823TQ (https://www.supermicro.com/products/chassis/2U/823/SC823TQ-653LPB).
I have now several options to create my zfs2:
- 6x6tb = 36 tb (voilating the one gb ram / tb hdd)
- 6x4tb = 24 tb (would be enough for now, but run out of space sooner than I'd want to)
Getting a different case that supports 8 hdds:
- 8x4tb = 32 tb
this would actually be my preferred choice, but I think to remember from one of the beginners guide that a zfs2 should be setup in 2^n+2 numbers of drives (4, 6, 10,...)
I can't find where I read about this rule, but I think to remember that it had something to do with compression turned on or not.
Once the first system is up and running, I want to build a second one for an off site backup. For this one, I was considering using 8x4tb 2.5" as it would only be synced once a day for about 30-60 minutes.
this setup would give about 6-8 years of freedom. As the system is ram wise maxed out, I'd build a new nas after that time.
So my two main questions are:
- is it a no-no to use 8 drives in a zfs2
- are the seagate barracuda 4tb 2.5" hdds a bad idea for the backup nas (I would like them, because they are much lighter. The daily backup would cover the important work data. Once a month I would bring the backup on site and sync non essential data (movies and such), which are too much traffic for the wifi bridge the off site backup is connected with. Therefor, I wouldn't mind a light setup)
Any help and input is greatly appreciated.
