White paper

conclusion When evaluating HBAs for a demanding data center environment, customers need to carefully examine how the HBAs will perform under business conditions, running actual business applications. Customers should carefully evaluate the conditions under which performance tests are run, as well as the design characteristics of the HBA, to ensure they deliver the needed throughput for applications.

The Emulex LPe11002 thus provides nearly twice the bandwidth of the Qlogic QLE2462 and significant transactional performance advantages at the data sizes most often used by business applications. The Emulex dual-channel LP11002 and LPe11002 4Gb/s HBAs and LP1105/ LPe1105 based Blade Server solutions offer the highest data throughput performance available for high performance Fibre Channel storage computing needs.

Key Messages Emulex dual-channel 4Gb/s Fibre Channel HBAs offer the highest performance for critical business applications over the Qlogic QLE2462:

c 36% greater IOPS at block sizes used by Oracle, SQL and Exchange

c Over 640 MB/s (78%) greater data throughput c 27% greater CPU efficiency
