Servers: Database consolidation on Dell PowerEdge R810 servers

Microsoft SQL Server 2000. We measured how many of those
workloads the new Dell PowerEdge R810 solution could host. The
new server ran Microsoft Windows Server 2008 R2 and Microsoft
SQL Server 2008 R2. We detail the test results in The Dell
PowerEdge R810 performance story section of this Guide. The Dell
PowerEdge R810 solution was able to consolidate 24 of these
workloads while still maintaining the same average orders per
minute (OPM) as the solution it replaced.
That consolidation could deliver payback in less than 12 months
and an ROI of 224 percent after 3 years.

Figure 1: The payback period and accumulated estimated costs for the 24 servers
and 12 storage arrays in the HP ProLiant DL385 solutions and the server and two
storage arrays in the Dell PowerEdge R810 solution. The Dell PowerEdge R810
solution delivers payback and savings within the first year. Lower costs and higher
savings are better.
Figure 1 graphs the payback period and the cost savings of the Dell
PowerEdge R810 solution. The line representing the Dell
PowerEdge R810 solution accumulates the initial investment cost
and the monthly costs of the solution. The initial investment cost
includes the list price of the server and the storage arrays as well
as the costs of migrating from the HP ProLiant DL385 solutions to
the newer Dell PowerEdge R810 solution. The line for the HP
ProLiant DL385 solutions shows the accumulated costs of these
solutions. The lines cross at the end of the payback period, the
point at which solution savings equal the initial investment.
