I'm new to UnRAID and planning to build my first server. Workload will be combination of NAS and backup for ~10 systems, plus ~10-15 VMs and/or containers running various mostly business oriented applications. I've read in the manual that support for SSDs is experimental, and not quite sure what it actually means. I said goodbuy to rotating drivers quite a few years back, and not keen to come back to them. Plus I don't have any budget to buy them, or anything for that matter, I have to use what I have currently available and not in use. And it so happens that I have 33TB of SSDs, 20 GB is nvme, the rest is SATA. I also have Intel 9980XE and 128GB of RAM.

 

My quations are:

- what does experimental support for SSDs mean?

- Will I be OK running everying on flash storage?

- Are my CPU and RAM enough for 15 VMs/Containers. To clarify, this will be server type VMs, no desktops, non GUIs, no hardware paththrought. OS on all of them will be Linux.

 

Thanks!

Thanks for the quick reply! It's a bit surprising that there is no TRIM for disks in data pool. But from your description it appears that I can have all my storage in cache pool with appropriate raid configuration of that pool. Is my understanding correct?

 

Thanks again

You must have at least one data disk in the array.

 

This FAQ talks about how to set up the different btrfs raid configuration for the cache pool:
