Agilent Hits High-Scale SAN Notes

Agilent Technologies Inc. (NYSE: A) today announced enhancements to its SAN testing platform that the company claims increases its test capacity by 100 times (see Agilent Scales Up SAN Tester).

New features Agilent has added to the 1730B SAN tester are device virtualization, host bus adapter (HBA) behavior emulation, and a capture buffer for failure analysis. The product is able to simulate up to 126 virtual devices behind each physical test port -- for up to 2,000 devices in a 2U-high chassis.

"As SAN fabrics double in size each year, testing them with actual servers and storage devices becomes increasingly challenging and expensive, reaching the scalability limits of traditional test methodologies," Agilent said in its press release today.

Agilent, however, is best advised to downplay the high-scale testing attributes of the 1730B in its marketing -- the Fibre Channel community clearly doesn't appreciate anyone calling attention to the fact that its products aren't capable of supporting high-scale fabrics today.

A luminescent example of this was the reaction of the Fibre Channel Industry Association (FCIA) to Spirent Communications' launch last month of its Storage Routing Test (SRT), which is designed to simulate up to 239 Fibre Channel switches in a single fabric. (It turns out that the test was actually developed by Cisco Systems Inc., which then licensed it to Spirent.) (See Spirent: FC Switches Fail to Scale and Source: Cisco Licensed Test to Spirent.)
