Hmmm not yet sure - I think writing via NFS is the biggest problem. Anyway, almost finished the work for a 'generic collector' and data visualizer which allows us to better correlate them to each other on the fly (i.e. no rrd pain) and understand the numbers hopefully a little bit better ;-). > drawback of using single F20 is that you're trying to minimize both > with the same device. Yepp. But would that scenario change much, when one puts 4 SSDs at HDD slots instead? I guess, not really or would be even worse because it "disturbs" the data path from/to HDD controlers. Anyway, I'll try that out next year, when those neat toys are officially supported (and the budget for this got its final approval of course).
