Performance and Validation Testing for the FCoE Protocol




SANBlaze VirtuaLUN storage emulation for FCoE is the key piece of test equipment for anyone developing products supporting the FCoE storage protocol. The VirtuaLUN feature set provides a unique set of functions applicable in all aspects of a product life cycle: from development to design validation and test and QA. The ability to emulate FCoE targets and initiators with a wide range of configurable attributes provides engineers with a flexible, scalable tool to simulate real Data Center Ethernet and SAN environments, at a fraction of the cost of real devices.



The VirtuaLUN provides full control and programmability of SCSI and network parameters, allocating unique storage test conditions for network testing and development.

For target emulation, an FCoE target can be a disk, a tape, or a collection of each, such as a tape changer or storage array. Easily configurable target environments with optional storage profiles can be edited and saved for reuse. Multiple error conditions and triggers allow for complex error injection. RAM based targets provide low latency targets for performance testing. In addition to targets such as disks and tapes, SANBlaze FCoE emulation provides emulation of FCoE switch ports. The ability to program complex and varying range of target configurations, emulate switch ports and save and restore multiple target configurations provides a flexible, cost effective and invaluable tool for development, test and QA labs.

Initiator emulation delivers the ability to drive FCoE traffic, inject errors, send specific or custom op codes in an easy to use, scriptable platform. The ability to combine FCoE traffic with other network traffic allows for simulated load. Custom command generation and predefined tests provide simulated host environments. Auto connect and probe features quickly identify targets to test. Features such as Read/Write/Compare testing, error injection and a custom command builder provide an environment to simulate single or multiple FCoE initiators. Test cases can be saved and restored with a single command. Tests can be started via command line, scripted or via an easy to use Web based interface.
