WHITE PAPER
Figure 2 shows the total Exchange transactional IOPS as measured by the
Jetstress test. With no cache enabled in the QLogic 10000 Series Adapter,
Jetstress measured 1056 transactional IOPS. In this case, all I/O traffic
makes the round trip from the server to the SAN storage array. At
100 percent cache, the cache size is equal to the LUN size in this test. The
measured IOPS of 5,270 has increased by nearly 400 percent.

Figure 3 shows the Exchange I/O read latency as measured by Jetstress.
With no cache enabled in the QLogic 10000, Jetstress measured the
latency at 4.724ms. As with transactional IOPS, all I/O traffic makes the
round trip from server to the SAN storage array. At 100 percent cache, the
latency fell to 0.922ms, an 80 percent reduction in this test.

Summary and Conclusion
QLogic continues to be the industry leader in delivering high-performance
I/O solutions to data center customers. The IOPS and latency of the QLogic
10000 Series 8Gb Fibre Channel Adapter is best-in-class and provides
an unprecedented high level of performance, superior scalability, and
enhanced reliability that exceeds the requirements for next-generation
Exchange environments. The unique caching solution of the 10000 Series
Adapter has the increased performance needed to meet the escalating
requirements of Microsoft Exchange Server. The results of the benchmark
tests demonstrate the I/O performance and scalability advantages of the
QLogic 10000 Series Adapter to Exchange Server performance, which
results in overall reduced total cost of ownership (TCO).
Because Microsoft Exchange is one of the most prevalent, business-critical
applications in enterprises, administrators go to great lengths to ensure
optimal performance. Administrators consider scalability and performance
as major factors when they work to improve Exchange performance. The
QLogic 10000 Series Adapter provides the technology to improve the
scalability and performance superiority of Exchange, which makes it the
right choice for Exchange administrators.
Exchange environments are carefully designed to cater to varying and
unpredictable loads. As heavier demands occur in the data centers, the
SAN must meet minimum business requirements for higher performance.
QLogic 10000 Series Adapter supports the required performance
scalability—400 percent increased IOPS and 80 percent reduced latency—
which makes a positive impact on an organization’s bottom line. The
QLogic FabricCache 10000 Series 8Gb Fibre Channel Adapter with built-in
I/O caching is designed to meet the ever-increasing needs of Microsoft
Exchange platforms.
