WHITE PAPER

Key Findings

The QLogic

FabricCache™ 10000 Series 8Gb Fibre Channel Adapter enhances transaction and latency performance for Microsoft

Exchange Servers by optimizing random read-intensive workloads that are inherent in Exchange and e-mail applications. The QLogic

10000 Series technology is implemented as a PCIe

-based intelligent I/O device that provides integrated Fibre Channel storage network

connectivity, flash memory caching, and embedded processing. The 10000 Series technology makes caching I/O data from Exchange

entirely transparent to the host.

QLogic’s caching technology in the QLogic 10000 Series Fibre Channel Adapter enhances Microsoft Exchange with:

• Increased transactional IOPS by up to 400 percent

• Decreased Exchange I/O read latency by up to 80 percent

• Overall improved performance in the Exchange environment

White Paper Executive Summary Increased demands on the Microsoft Exchange Server make it critical to optimize its I/O performance in the SAN. The QLogic 10000 Series 8Gb Fibre Channel Adapter meets that need for high performance. By implementing a unique I/O caching architecture with Fibre Channel connectivity, the 10000 Series Adapter significantly increases the performance of transactional I/O (IOPS) and I/O read latency for large Exchange data volumes.

Software Used for Exchange Jetstress Testing Software Description Operating System Windows Server 2008 R2 Exchange Performance Validation Tool Exchange Jetstress 2010 64-bit version 14.01.0225.017 Exchange 2010 System Simulation ESE.dll File 14.01.0218.012 (Microsoft Exchange Server 2010 SP1) Quantity of Mailboxes 1,000 Mailbox Size 200MB Database Size 200GB Exchange Performance Results Using Jetstress Figure 1.

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.
