Hey All,

 

Bought a pro license and I was hoping to convert my windows server 2019 to Unraid.  I use it mainly as a media server using plex.  

 

Here is what I was wanting to run on the Unraid server

- Plex

- Radaar

- Sonaar

- Ubiquiti controller

- Blue Iris

- Suricata 

- Next Cloud

- Calibre 

 

Had a few questions\concerns before proceeding with the conversion.

 

1.  Can the Parity disk be the same size as the other disk?  

 

2. Will 1tb be sufficient for a cache pool?  I want the flexibility to run at least 2 VMs.  One will be for Suricata and the other will be for Blue iris.  

 

3.  Is it best practice for app installs in be in the cache pool?

 

4.  Since Unraid is booted off USB, what happens if the USB get corrupted?  

 

I was hoping to salvage some parts from my old server to save on money.  I will most likely get a new motherboard and CPU as my current setup struggles with 4k transcoding.  Any suggestions will be greatly appreciated.

- CPU - AMD Ryzen 7 1700

- x6 8TB drives

- RAM 16GB DDR4

 

 

1. You can have 0, 1, or 2 parity disks. Each parity disk must be at least as large as the largest single data disk. Unraid allows disks of mixed sizes in the parity array.
2. 1TB should be more than enough. Just don't try to cache the initial data load.
3. Yes. The default user shares named appdata, domains, system should not be on the parity array, so dockers/VMs will perform better, and so array disks can spin down since these files are always open. https://wiki.unraid.net/Manual/Shares#Default_Shares
4. You must always have a current backup of the boot flash drive. If it gets corrupted, you can restore from backup. If it fails completely you can restore the backup to a new flash drive and transfer your license.
