I am about to build out a new server, just ordered a X8 based server, to be more accurate: SUPERMICRO 4U 846E16-R1200B X8DTE-F
I currently have 10 3 TB drives that I am using in a old NAS box, and want to later utilize them in my new build, but first want to start fresh with 4 TB drives, migrate the data over, and then pop the old drives in as a new VDEV.
I am just trying to make sure my redundancy assumptions and ideas are correct, don't want to do all this work, overlook some silly statistical issue, and have a situation where I don't have enough redundancy.
My "new" 4TB vdev is probably going to be 8 4 TB drives, with this I plan on using RAIDZ2, that should be enough with this many drives/volume size, correct?
Then I will plan on throwing my old 3 TB's in, and have all 10 of those as a RAIDZ3 vdev. Sound good?
And now, one more question, because you can't write a forum post without thinking of something else midway through.
Are there any issues I may have running these two vdevs in the same pool? Would it be a "better" idea to run them as different independent pools? I am new to freenas and ZFS, and I know just enough to be dangerous as some would say. Just trying to make sure my assumptions are all correct.
For reference, I will have a HBA with LSI 9211-8I firmware on it and a 24 port backplane. As far as I have been told thus far, I will only need to run 1 SAS cable to the backplane, will that have any issue with my proposed setup?
Thanks guys!
