Hi everyone,
After almost two years of using OMV, my NAS is running out of space so it is time for an upgrade! I am not a complete n00b but an extra pair of eyes looking over my build and/or an expert opinion would be much appreciated. Currently I am running this build:
Mobo | Supermicro X10SLH-F |
CPU | Intel Core i3-4150 |
RAM | Crucial CT102472BD160B |
Case | Fractal Design Arc Mini R2 |
PS | Seasonic S12G 450W |
OS SSD | Crucial MX100 128GB |
Storage HDD's | 2 x 3TB WD Red NAS |
Currently using ext4 as file system with SnapRAID as a safeguard but I want something more secure. After a day of searching and reading up on the latest developments considering Btrfs and ZFS, I've chosen to go the ZFS Raidz2 road. My plan is to fill up all the 6 disk trays with 3TB disks which leaves me with 12TB of space according to this and this calculator. My plan was to use 5 3TB disks and 1 TB disk to setup the initial ZFS storage tank, copy the data from my data disk to the tank, take the 1TB disk out, put the 3TB disk in and let the array resilver. Is this a possibility?
Since the motherboard has 6 SATA ports and the OS disk takes one, I need to buy a hard disk controller card with at least one SATA controller. Can I buy an el cheapo one or do I need to buy something like a Highpoint Rocket 640L in order to achieve decent read/write speeds? Should I connect the storage HDD's directly to the motherboard and the OS disk to the SATA controller?
Also, I am planning on buying at least one extra ram module of the same make and model. I've read that while using ZFS for each TB you need approximately 1GB of RAM. So one should be enough or do I need more?
Thanks in advance for any tips/opinions/etc!
