OPM in each VM equivalent to that of the HP ProLiant DL385 solution. The total number of VMs the Dell PowerEdge R710 solution could handle determines the replacement factor. Based on our specific workload, the replacement factor is seven. Figure 1 depicts this replacement factor for replacing seven AMD Opteron 254- based HP ProLiant DL385 solutions with a single Intel Xeon Processor X5550-based Dell PowerEdge R710 solution, as well as the initial investment payback time of under 18 months.

Four benefits of the Dell PowerEdge R710 solution contribute significantly to the cost savings for this solution: • Replaces up to seven HP ProLiant DL385 servers with HP StorageWorks MSA30 storage arrays. The increased I/O capacity, database performance, and memory efficient design of the Dell PowerEdge 2 R710 solution enables consolidation of multiple older systems for the specific workload we tested. • Uses slightly more than one-fifth of the power of the seven HP ProLiant DL385 solu

The DS2 driver application creates an orders-per-minute performance counter on each client machine. While the DVD Store client application visually outputs OPM at 10-second intervals, we chose to collect this OPM metric via a performance monitor counter on each client machine at 1-second intervals. For more details about the DS2 tool, see http://www.delltechcenter.com/page/DVD+Store We ran this workload on the Dell PowerEdge R710 server and the HP ProLiant DL385 server for 30 minu

Editing the ds2_create_cust.c module We had to make the same changes to the ds2_create_cust.c module that we made to the ds2_create_orders.c module. On the command line for the ds2_create_cust.c module, we specified the size. The available options were S (small), M (medium), and L (large). We added the case T for the 10GB database. In the switch statement that sets the values for the variables max_cust_id and max_prod_id, we added cases that assigned them the proper values for the 10GB da
