Hey,
I have a build for which I need to ensure rebuilds do not impact the array, I assume I would be best of doing mirrored vdevs rather than RAIDZ2 or RAIDZ3 vdevs to reduce the impact of rebuilds?
The purpose of the array is a backup target, it's worth noting my backup software does perform consistency checks on the data, hence my worry about rebuilds impacting read/write speeds!
Also it worth having a NVMe PCIe slog? I need to ensure data is committed to the array without fail, I want to turn on " sync=always" to ensure this.
My Build is below.
Processor - 2 x Intel® Xeon® 5122 Gold Processor 3.60GHz 4 core (worth considering a 2 x 3.4Ghz 6 core?)
Memory - 256GB 2666MHz DDR4 ECC
HBA - LSi SAS HBA 9300-4i4e SGL
SSD - 2 x Intel® SSD DC S4500 Series (Freenas OS Drives in mirror).
HDD - 36 x 12TB 7200 RPM 3.5" 12GB SAS
Network Card - Supermicro Quad Port 10Gb/s SFP+
