Server consolidation with the Dell PowerEdge M620

CONSOLIDATE AND SAVE

Upgrading your current servers that run only one application instance to a new

server and storage solution with multiple application instances in virtual machines has

the potential not only to increase your performance and server utilization, but also to

save you money. Furthermore, upgrading your applications from the older 2007 version

to Microsoft Exchange Server 2010 also lets you benefit from the latest features

available for your mail server.

Four times the mailboxes, more users per watt

As Figure 1 shows, the Dell PowerEdge M620 was able to run four virtual

machines each running a 2,000-user Microsoft Exchange Server 2010 workload, while

the HP ProLiant BL460c G6 server ran one 2,000-user Exchange Server 2007 workload.

Figure 1: The superior

performance that the Dell

PowerEdge M620 delivers

means that you can

consolidate four 2,000-user

workloads into just one server

and support the same number

of users.

Users

Exchange users supported

Supporting a high number of users is important, but so is the response time the

server provides for those users. Not only was the Dell PowerEdge M620 able to support

more users, it also provided better response times for those users – up to 70.1 percent

better response time than the HP ProLiant BL460c G6. Figure 2 shows the average

response time (MSExchangeIS\RPC Average Latency counter), in milliseconds for the

two servers. (It is worth noting that Microsoft recommends that for best performance

the MSExchangeIS\RPC Average Latency counter stay below 10 milliseconds on

Exchange 2010 and below 20 milliseconds on Exchange 2007.)
