Subject Re: Need to evaluate a cluster
Date Wed, 09 Jul 2014 19:31:03 GMT
367 nodes sounded quite high for that amount of data per day. You might
need 367 disks, but do your nodes have more than one disk?

You may also take into account the compression factor that you are likely
to use for the data on the cluster.
