Hi, I've looked the forums, but didn't find anyone talking about full flash freenas. We've been thinking about a supermicro case with 24x 2,5" slots, filling it with 1TB SSD drives in 2x12 mirror (raid-10 like) config, with 64-128G RAM, 2x 10Gb NIC.
Has someone experience with such a machine?
Would a separate ZIL on a very fast PCIe SSD still make sense with that?
How many IOPS could we expect? Each SSD has realistic 40k IOPS, so 12x40k would be 480k IOPS. Or are there limits before that? On 4K IOs, that would be 1875 MB/s, so two 10Gb/s NICs would be saturated.
