Dell Active System 800 converged infrastructure solution: User
collaboration performance
our original test (see Figure 2). Additionally, the order-processing capacity approximately
doubled the prior output, showing near-linear scaling.
Workload
Measurement
Order-processing workload
126,448 orders per minute
Microsoft Exchange
10.217ms latency (<50ms is acceptable)
1.662 messages per second
Microsoft SharePoint
8.004 requests per second
Microsoft Lync Server
8.302 IMs per second
Figure 2. Results from heavy workload testing of Microsoft collaboration and database workloads.
Not only did the end-user experience remain acceptable for collaboration applications
and the order-processing workload scale appropriately, when we ran this heavier utilization
scenario, the applications still used just 72 percent of the available processor resources
3
and
6,648 storage IOPS, leaving still more resources for additional business use. Figure 3 compares
the performance of our base and heavy workloads for the collaboration applications.

and Lync Server performance
across the two tested workloads.
Increasing other workloads on the
Active System 800 had no
appreciable effect on application
transactions.

 What does this mean for data center managers? These tests show that the additional
resource availability on the Active System 800 can be used to host additional business
applications, potentially further reducing infrastructure acquisition costs and minimizing
data center sprawl.
 What does this mean for the end user? The ability of two servers in an Active System
800 to run three simultaneous collaboration applications and four heavy order-
processing workloads means that users need not worry about resource availability while
doing their daily tasks.
