 The total cost of running the new hardware would be $5,913. That would imply a savings rate of $21,576 per year. The job slot count would be 112 but with hyperthreading technology that can be doubled. We'd still want the 1,792 memory footprint (8 gb/core) and the gigaflops still far exceeds Dell's performance.

+Within two years, the new hardware (about $41K) will have paid for itself based on the low water mark (Dell's cost would equal $55K). We still need to adjust some minor issues:
-- there is enough Infiniband ports available to put all new nodes on such a switch
-- the internal disks need to be of higher speed (10K) or better of size 300 GB or larger (mimicking the Dell disk arrays)
-- perhaps go to 9 nodes total
+  * there is enough Infiniband ports available to put all new nodes on such a switch (add cards and cables cost)
+  * the internal disks need to be of higher speed (10K or better) of a larger size (300 GB or larger) mimicking the Dell disk arrays (add costs)
+But it is all very doable within budget of $45-$55K
 The end.
