ALISO VIEJO, Calif., August 26, 2002 -QLogic Corp.
(Nasdaq:QLGC), the company that powers storage area networks
(SANs), today announced that its SANbox2* 16 Port Fibre Channel
switch outperformed all competitive offerings in tests performed
by QLogic and conducted with Spirent Communications' SmartBits
6000B and SmartFabric testing tools, the industry-first product
for evaluating network switch performance.
Using the SmartBits 6000B with FBC-3602A test modules and
the SmartFabric application, the SANbox2 16 port switch achieved
the maximum wire-rate throughput of 2GBits/sec Fibre Channel
simultaneously for all ports (aggregate of 3,362 Mbytes/sec).
In addition, the QLogic SANbox2 performed with up to 96 percent
less latency (the amount of delay added by a device) compared
to all competitive switch products. The SANbox2 demonstrated
minimal and predictable latency under peak traffic conditions,
which is a key performance requirement for most storage applications
such as OLTP (On-Line Transaction Processing), database transactions
and video streaming/authoring.
"The SmartBits performance analysis products from Spirent
were an obvious choice to test our SANbox2 switch in a variety
of traffic load scenarios," said Mike Knudsen, senior
vice president, QLogic Network Storage Group. "SAN designers
and administrators require consistent and predictable switching
performance for nominal and peak traffic cases. This testing
confirms that the SANbox2 switching architecture provides
industry-leading performance at the lowest cost in the market."
Testing Details
In measuring throughput, all 16 ports of the SANbox2 were
tested simultaneously in pairs and mesh traffic patterns using
the SmartBits 6000B, FBC-3602A test modules, and SmartFabric
application from Spirent. The theoretical maximum throughput
was calculated by the Spirent tools for all frame sizes allowable
by the Fibre Channel standard (60 - 2148 bytes), resulting
in the switch aggregate of 3,362 Mbytes/sec for maximum size
frames. A maximum latency of 0.5 microseconds was achieved
across the full range of traffic load scenarios: 20 percent
to 100 percent of the maximum traffic burst rate for 2GBit
Fibre Channel. By comparison, under identical conditions the
latency of other products reached 15 microseconds or more,
which is equivalent to 30 times the worst case for SANbox2.
