A four-node Isilon cluster is being used in a Hadoop workflow with a parity protection of N+2:1. The HDFS protocol has been enabled and is being used to access data. How many additional copies of data are written into the Isilon cluster using HDFS?
N+2:1 is protection 2 disks 1 node, which means 2 FEC
As this is HDFS is most likely small foles, so probably 1 data + 2 mirrors, so ==> 2 additional copies of the data.
