Brocade, which has had a reputation for trying to protect its turf by inhibiting interoperability with its Fibre Channel switches, is now cooperatively working behind the scenes with Cisco Systems Inc. (Nasdaq: CSCO), McData Corp. (Nasdaq: MCDTA), and QLogic Corp. (Nasdaq: QLGC), according to several industry sources.
Last week, Byte and Switch reported that QLogic appeared to have reverse-engineered Brocade's native-mode operation (see QLogic Learns Brocade Lingo). In fact, say industry sources familiar with both companies, this is the result of joint development work by Brocade and QLogic.
The Brocade/QLogic interoperability project started about three months ago, when a major New York financial institution that is an IBM Corp. (NYSE: IBM) customer was attempting to connect an IBM BladeCenter blade server system to its existing Brocade SAN. QLogic's Fibre Channel switch silicon is embedded onto a blade on the BladeCenter (see QLogic FC Ships in IBM Blades).
The problem is that, ordinarily, certain advanced Brocade features become disabled when Brocade switches are connected to third-party switches in "interop mode" using FC-SW-2, the industry standard for Fibre Channel. One of the features lost when the QLogic-enabled BladeCenter was plugged into Brocade's SAN was hardware-enforced World Wide Name (WWN) zoning, a security feature that isolates zone configurations from physical changes.
