WHITE PAPER

Key Findings

The QLogic 2500 8Gb adapter product family showcases the next generation of FC SANs, with an increase in performance:

• Performance: 33-percent higher IOPS when upgrading to the 8Gb adapter. Tests demonstrated that in existing 4Gb infrastructure

(4Gb adapter, 4Gb switch, and 4Gb storage), performance increased by over 33 percent by replacing the 4Gb adapter with

an 8Gb adapter.

• Throughput: 100-percent higher throughput was achieved (1600MBps versus 800MBps) by using the QLogic 2500 series 8Gb

adapter and QLogic 5800 8Gb switch in comparison to existing 4Gb adapter/switch configurations.

White Paper Executive Summary As 8Gb Fibre Channel (FC) Storage Area Networks (SANs) become a reality, IT professionals must ensure a balance within the data center infrastructure to meet the Minimum Business Attributes. With continued demands in the data center, it is imperative to deploy a scalable architecture to meet a full spectrum of concerns, including cost, performance, and backwards compatibility.

White Paper 4Gb Test Setup Test Results The test results demonstrated the performance increase of the 8Gb adapter infrastructure over the 4Gb adapter infrastructure. The graphs in the following paragraphs identify and compare performance while executing sequential reads and write operations, which provided maximum IOPS and throughput measured in the following configurations: Sequential Read/Write Throughput QLogic 8Gb FC adapters meet the demand of increased virtual server density.

White Paper Sequential Read/Write IOPS higher performance. Data center infrastructure must balance addressing these emerging challenges and protecting the current investments. While enterprises must deploy a scalable architecture to meet future challenges, they must also ensure complete backward compatibility, optimal costs, and manageability. At block sizes below 8KB, the QLogic 2500 series 8Gb FC adapter demonstrated a 45 percent improvement over 4Gb adapters.
