QLogic Outperforms Emulex
the QLogic Common Performance test Platform is used to provide
performance benchmark results, offering it administrators and system
architects visibility into product performance in a clear and unbiased
manner. QLogic performs testing to evaluate adapter capabilities and
adapter performance in real-world enterprise application environments.
QLogic has compared the out-of-box performance of its 8300 Series
10Gbe Converged Network adapter with the emulex OCe11102, using the
test setup described in the QLogic Technology Brief, QLogic Platform and
Methodology for Product Evaluations

.
Application Workload
the results of this testing, which emulates real-world Oracle and Microsoft
exchange Server
workloads using the QLogic Common test Platform, are
presented in this white paper.
QLogic continues to be the industry leader in delivering high-performance
i/O solutions to data center customers. the iOPS and throughput of the
QLogic 8300 Series 10Gbe Converged Network adapter is best in class and
provides an unprecedented level of high performance, superior scalability,
and enhanced reliability that exceeds the requirements for next-generation
data centers. the results of the benchmark tests demonstrate the i/O
performance and scalability advantages of the QLogic 8300 Series 10Gbe
Converged Network adapter over the emulex OCe11102 10Gbe adapter in
real-world deployment environments.
Scalability Architecture for Increased VM Density
VM scalability was tested by simulating a base workload for a typical VM
density in today’s environment. the load was then scaled by four times (4X)
the VM load, and then eight times (8X). this simulation projects the growth
required for a typical data center business as the number of VMs increases.
QLogic 8300 Series adapters meet the demand of today’s data center
(represented in this section of the white paper as virtual server workload).
the figures in this section illustrate how QLogic 8300 Series Converged
Network adapter performance scaled better than emulex as the workload
representing VMs increased from one to eight times the load. as the
application scaled to an eight-times VM load, the QLogic 8300 Series
Converged Network adapter maintained high iOPS, showing the i/O support
required for high density hypervisor applications. the emulex adapter, on
the other hand, demonstrated consistently lower performance (72 percent
lower iOPS than the QLogic 8300 Series Converged Network adapter, as
seen in Figure 3).

Read-Write IOPS on Benchmarking Tool
QLogic’s iOPS were higher than emulex by 44 percent as shown in Figure 2.
emulex OCe11102 iOPS peaked at 504,000, when running an eight-times
VM load at a 512 bytes block size.

Read-Write Scalability in Real-World Workloads
typical real-world SaN workloads represent the block sizes and i/O activity
that models real-world workloads (like MS exchange or Oracle databases).
to show scalability performance in SaN environments, QLogic tested
the adapters using 4kB and 8kB block sizes. Figure 3 shows that even
though read-write iOPS were at parity at the one-times VM workload, the
performance of the OCe11102 was 45 percent lower than the QLogic 8300
Series Converged Network adapter when the number of VMs scaled to the
eight-times load. across increasing VM loads, the QLogic adapter scaled by
220 percent and 150 percent respectively for 4kB and 8kB block sizes, as
shown in Figures 3 and 4.
Figure 3. VM Scalability Performance with Increasing VM Load – 4kB Block Size
the QLogic 8300 Series Converged Network adapter continued to provide
scalability and performance as demonstrated in the aforementioned
benchmarks.
