QLogic FabricCache Caching Technology
Delivers Scalable Performance to
Enterprise Applications
The QLogic 10000 Series delivers scalable performance to
enterprise applications and reduces the performance gap
between these applications and their storage subsystems.
EXECUTIVE SUMMARY
The growing disparity between the performance of CPU-based and
disk-based storage continues to grow. Applications that are Web 2.0,
mission-critical, I/O intensive, virtualized, and clustered continue to put an
additional burden on processors and slower storage, which lowers overall
application performance. These increased performance demands on the
enterprise data center require application performance improvements
using innovative solutions that can scale across the enterprise
infrastructure.
The QLogic 10000 Series Adapter technology delivers a unique solution
optimized to address the growing performance gap between what the
processor can compute and what the storage I/O subsystem can deliver.
With a simple adapter deployment model, the seamless approach
combines enterprise SAN connectivity with shared server-based I/O
caching. The QLogic 10000 Series Adapter provides dramatic and scalable
performance improvements to the widest range of enterprise applications.
This white paper provides an overview of the application performance
capability of the QLogic 10000 Series Adapter. A query workload from
the Transaction Processing Performance Council (TPC) Benchmark™
E (TPC-E) was used to generate database queries. TPC, an online
transaction processing (OLTP) workload, provides real-world, I/O-
intensive transactions that simulate activities found in complex database
application environments. The QLogic 10000 Series meets the application
performance challenge and accelerates performance across the entire
enterprise.
KEY FINDINGS
The QLogic ® FabricCache™ 10000 Series 8Gb Fibre Channel
Adapter enhances application performance by optimizing random
read-intensive workloads running in clustered, shared resource
environments. The QLogic 10000 Series technology integrates Fibre
Channel storage network connections, a flash memory interface, and
embedded processing. The technology delivers scalable performance
to enterprise applications and reduces the performance gap between
these applications and their storage subsystems.
QLogic’s caching technology in the 10000 Series Fibre Channel
Adapter delivers:
• Large application acceleration with modest cache configurations:
– In a single-server configuration, the adapter delivers 7.75 × the
performance over having no cache
• Performance that scales directly with the server infrastructure:
– In a multiserver (four or more) configuration, the adapter
delivers up to 22 × the performance over having no cache
• Remotely located cache performance difference of less than 10
percent compared to cache residing locally
