Anthony D'Atri's comments in this PR provide several good avenues for the expansion of and clarification of the hardware recommendations documentation. Among his comments are these ideas:
- MDS (metadata server) nodes benefit more from fast clock rates than from beefy (at the time of this writing, "quad-core or better") CPUs. The example that Anthony gives is "a 4-core 3.5 GHz model [is] preferable to an 8-core 2.5 GHz SKU".
- We might mention EC parity (erasure coding parity) and hash computation.
- More explanation of "isolation" as a term in the context of and as it applies to OSDs might not be unwelcome.
