Microsoft Exchange consolidation and TCO: Dell PowerEdge R720xd vs.
HP ProLiant DL380 G6
ABOUT THE DELL POWEREDGE R720XD
According to Dell, the Dell PowerEdge R720xd rack server is designed for
workloads that are hungry for storage and I/O performance, such as Exchange servers. It
combines highly expandable memory and improved I/O capabilities with large storage
capacity. Powered by Intel® Xeon® E5-2600 processors and reinforced with reliability,
availability, and serviceability (RAS) features like hot-plug fans, disks, and power supply
units (PSUs), the Dell PowerEdge R720xd delivers strong performance and reliability.
ACHIEVE PAYBACK IN 19 MONTHS BY CONSOLIDATING THE EXCHANGE
WORKLOAD OF FOUR HP PROLIANT DL380 G6 SERVERS
Tests in our labs using the LoadGen benchmark show that one Dell PowerEdge
R720xd running Microsoft Exchange Server 2010 can run the same 1,000 user-workload
of four existing HP ProLiant DL380 G6 servers running Microsoft Exchange Server 2007
and still maintain room for growth.
To illustrate the cost savings this consolidation can provide, we calculated the
costs for a hypothetical enterprise planning this migration and compared those costs to
those of retaining the existing servers. We found that, thanks to savings in software and
hardware support, server administration, and data center costs for energy, ports, and
space, the Dell PowerEdge R720xd can pay back the investment in hardware and the
migration effort in less than 19 months. Figure 3 summarizes the costs for the two
solutions.
