Hi
After having bitter experience with a USB setup that wasn't tested enough..., I would now like to double-check that I'm aiming for a good setup.
I am planning my system based on my old desktop:
- Board: ASUS R.O.G. Maximus V Formula, LGA 1155, Intel Z77 (6+2 SATA ports)
- CPU: Intel Core i7 3770K, 3.50 GHz, 4-core
- RAM: 32GB DDR3
- Broadcom's SAS 3008, 12Gbit controller
- Boot partition: 2x 960GB Kingston A400 SSD (direct connection to board)
- Data pool for media files: 3x 8TB Seagate HDD 7200rpm (via SAS Controller)
- Data pool for important data (including network boots for various other systems and NFS volumes for a Docker Swarm cluster): 3x 2TB Crucial SSD (direct connection to board)
- Data pool for backups/reserve: 2x 1.5 TB HDD 7200rpm (via SAS Controller)
Questions:
- - Are there any problems in this setup?
- In particular, I still have my former system disk left, a Samsung 840 Pro Basic, 256 GB SSD (approx. 500MB/s write rate). Does it make sense to use this as a cache or metadata disk for one of the pools or does it not benefit me?
- I also have a 2TB and a 3TB WD HDD (7200rpm) left that I could also use as cache/metadata. But I didn't find any precise recommendations in the documentation.
- Since these are not new disks, what happens if they fail? Can the data pool then simply continue to operate without a cache?
Thx for any help!
