Servers: Database consolidation on Dell PowerEdge R810 servers
13
As Figure 4 shows, the combined OPM of 24 SQL Server database
workloads on the Dell PowerEdge R810 solution were over 27 times
greater than the single HP ProLiant DL385 solution database
workload.

Figure 4. Combined orders per minute of 24 database workloads on the Dell
PowerEdge R810 solution versus a single HP ProLiant DL385 solution database
workload. Greater OPM is better.
Power savings
As Figure 5 shows, assuming we were running 24 HP Proliant
DL385 servers, each using one-half of the HP StorageWorks MSA30
external enclosure, and therefore a total of 12 enclosures, we
would significantly reduce our power consumption. Power
consumption at idle and under load both decreased by over 85
percent when switching to the Dell PowerEdge R810 solution. We
calculated this by taking the overall wattage from the HP ProLiant
DL385 solution, then multiplying the server wattage times 24 and
the storage wattage times 12. We contrast this with the total
power consumption of the Dell PowerEdge R810 solution. Lower
wattage is better.
