The number of compute and Isilon nodes
using Intel technology can be adjusted
independently to achieve the optimal ratio
of compute and I/O bandwidth
HDFS I/O ALWAYS comes through a rack-
local Isilon node which collects data blocks
from all other Isilon nodes across the
InfiniBand fabric (see animation)
(used only for MR copy phase) 1+ Gbps (used only for MR copy phase)
Shuffle I/O (75% of all I/O during terasort)

for optimal performance.
