Total usable volume size is only > about 22 TB (about 45 TB total with 2x replicate). Where are you reading the 20% from? If it is from the per process line in top, then that 20% is of a single core/hyperthread. It is not of the whole system. If you have an otherwise quiescent server and the "Cpu(s)" summary line at the top says 20%us, then you can extrapolate to under 20% of the total system. -- Mr. Flibble King of the Potato People
