Re:1, 2, 3...15, 22. (Score 2)

You see 22 cases. 16 in the cluster, the two controlling machines, and EMPTY cases. Misleading, I know. They'll be filling them in later. The top 5 machines in the nearest 3 columns, and the top one in the 4th column, are all currently in the cluster. The bottom machines in the two nearest columns are the controlling machines. The bottom four in the 4th column are not connected to the cluster yet. They also plan on adding another rack with 5 more machines for a total of 25 machines. (The cases can be seen sitting in a stack at the left side of the racks)
