8Gb Exchange Advantages
Microsoft exchange is one of the business critical applications in small,
medium, and large enterprises. it is critical for it Managers to go to great
lengths to ensure delivery on the guaranteed uptimes, scalability, and
performance of the exchange services provided. For most businesses, a
messaging system is one of the mission-critical tools for effective and fast
communication. as heavier demands occur in the data centers, the SaN
must meet minimum business requirements for higher performance.
the capabilities of the QLogic 2500 Series 8Gb FC hBa continues the
unsurpassed performance provided by QLogic Series hBas. the 8Gb hBa
offers increased performance and higher efficiency over 4Gb, which in turn
supports additional exchange Seats. the improved level of performance
offered by 8Gb will become increasingly necessary as the i/O performance
required for database backups, restores, and e-mail volumes increase.
QLogic has proved its scalability and performance superiority over its
competitors, making it the right choice for exchange administrators. QLogic
demonstrates the advantages of the 8Gb infrastructure with exchange. the
tests described in this paper were conducted with Microsoft’s Jetstress
utility. Jetstress has various options to generate the most commonly
used data patterns of Microsoft exchange. the tests performed were
Disk Performance, Mail Box profiling, and Microsoft exchange database
backups. the following figure shows a performance increase of 26 percent
using 8Gb hBas over 4Gb hBas, utilizing 40 threads per storage group.
Microsoft Exchange Backup
QLogic continues to provide scalability and performance as demonstrated
with the iOmeter in the following figure, identifying the through-put
performance differences between the QLogic 4Gb and 8Gb hBas. iOmeter
was configured to place the maximum possible load on the 4Gb and 8Gb
hBa. as customers purchase and utilize the 8Gb hBa and integrate into
8Gb SaNs and infrastructure, they expect optimum throughput through
both channels.
it is imperative to deploy a scalable architecture to meet the ever-
growing requirements of Storage area Networks (SaNs). the QLogic
2500 Series 8Gb Fibre Channel (FC) host Bus adapter (hBa) meets the
need for high performance to support the volume of data or throughput
(measured in MBps) and the load of data requests (measured by iOPS).
today’s SaNs requires increased performance supporting common
enterprise applications such as database, mail servers, and secondary
storage.
Without adequate performance for applications, productivity will be
impacted; the loss of efficiency will directly affect revenue. the QLogic
2500 Series 8Gb FC hBa increases data throughput over the previous
generation 4Gb hBa, providing applications additional performance for
future needs. Common enterprise applications must operate perfectly
and provide sustained performance when demand peaks.
this white paper focuses on the performance benefits of the QLogic
2500 Series 8Gb FC hBa over the 4Gb technology for key applications
and its scalability to meet the demands of today’s and tomorrow’s
applications. this paper also shows how QLogic’s 8Gb hBa performs
with Microsoft
® exchange seats as well as with the high-speed
requirements of Disk to Disk (D2D) backup, disaster recovery, and
Oracle
® applications.
