Just trying to find the right way to build out my FreeNAS box, I played around a little and I am back with a few more questions:
Dell r510 12 Bay 3.5 + 2 bay 2.5 internal
12x 2TB HDD
2x 1TB Samsung EVO SSD
1x 16gb Optane (in PCIE Adapter)
H200 Card in IT Mode
10gb SFP+ Card (running to 10gbe Switch)
2x - XCP-NG Hosts with connections to main 1gig network and 10gig storage network.
My use case will be VM disk storage and general file sharing and backup. I currently have an unRAID server that houses plex/emby media and other file storage. The end goal would be to keep mostly the media on the unRAID box and move all other file sharing and storage to the FreeNAS box. I would also backup critical files between them as needed.
I think for the non ssd pool I will go with 6x or 5x striped mirrors. This is mostly so I can upgrade the vdevs easier down the line. I don’t care too much about performance on the non-ssd pool. I am also trying to decide if I should keep two drives open to expand the SSD pool (more on that later).
For the SSD pool, I currently have the two 1TB’s in a mirror, but I think I would like more storage, so I may extend to add another mirror.
Ok, so questions:
- Besides the obviously size increase, will I see a significant performance increase in adding another mirror to the SSD pool? I am running up against the physical capacity of the server, and while I could expand to another chassis later on, I am not ready for that now. So space is a little limited.
- I currently running the server off mirrored usb drives. The server has been up for about a week and one usb already died. I am worried about this. But the usb drives are cheap enough. Which brings me to my next question…
- What to do with the optane? I currently have it as a SLOG on the SSD pool, but I am reading that this doesn’t really help. Should I make the optane the SLOG for the hdd pool? Or should I use it as a boot drive. If I use it as a boot drive, I would add another to mirror, but at that point I would also be out of PCIE slots. Which isn’t a problem now, but would be down the line if I wanted to use a SAS expander for more drives.
So…what is my best bet here? So many options. I may just be overthinking it. But I hope you can help so I have a great solid foundation for this storage server.
Thank you. Appreciate any help.
