I am back to my 24 drive ZFS project and I can't seem to find a scheme that pleases me yet.
RAID60 is where I am right now with 12 disks in striped 6xRAID-Z2 array. I was thinking of adding in my 3 NVMe as cache as I am messing with graid3 on them now for comparisons. That still leaves 12 drives to provision. Thinking of further nesting with raid600 or raid601.
RAID-Z3 is more protection than I need. Maybe I am wrong? Is using my 3 NVMe for ZFS cache the best use?
Maybe instead use 2 for cache and one for zil slog?
24 SAS2 disks of 450gb size was not the best arrangement, but I don't have much money into it.
I am just trying to learn how to work with disk cabinets and different storage arrangements.
I am using 3ea. SAS2-9207-8i controllers in a Chenbro 2U rack chassis.
Somewhat obsessively I bought a second 24 bay cabinet for 60 bucks. SuperMicro/Chenbro OEM
It has a different backplane arrangement for 8087 cabling with 3X8 drives versus my current 2X12 drive backplane.
I like the logical grouping of 3x8 as it jives better with the controllers being 8 ports.
Currently 24 drives are too much for a home lab but it does offer alot of flexibility.
Thinking maybe mirror these 2 storage boxes with 12 drives each for testing clustering filesystems like ceph and gluster.
I have a few dual port drives and would like to experiment with those. Especially on Supermicro EL2 backplanes.
That is a future project with SAS3 SSD's.
