test results
the test results demonstrated superior performance of the QLogic 2500
Series 8Gb Fibre Channel adapter over the emulex LPe12002 8Gb adapter.
the following graphs provide a comparison of QLogic vs. emulex 8Gb
adapter iOPS while performing sequential read, write, and read/write
operations.
the tests show that the QLogic 2500 Series adapter has a performance
advantage over the emulex LPe12002 8Gb adapter, especially at block
sizes supporting enterprise applications.
Sequential Read Operations
iOPS
at block sizes below 8KB, the QLogic 2500 Series adapter demonstrated up
to 48 percent overall improvement of sequential read iOPS over the emulex
LPe12002 adapter, as shown in Figure 2.

throughput
at block sizes above 64KB, the QLogic 2500 Series adapter showed a 4
percent advantage over the emulex LPe12002 adapter.
Sequential Write Operations
iOPS
at block sizes below 8KB, the QLogic 2500 Series adapter demonstrated up
to 18 percent overall improvement of sequential write iOPS over the emulex
LPe12002 adapter, as shown in Figure 3.
