SANBlaze VirtuaLUN storage emulation for NVMe over Fabrics (NVMe-oF™) is the key piece of test equipment for anyone developing products supporting the NVMe-oF storage protocol using Fibre Channel, RoCE/RDMA, and TCP/IP technology. The VirtuaLUN feature set provides a unique set of functions applicable in all aspects of a product lifecycle; from development to design validation and test and QA. The ability to emulate NVMe-oF targets and initiators with a wide range of configurable attributes provides engineers with a flexible, scalable tool to simulate real environments and test director class switch environments at a fraction of the cost of real devices.
The VirtuaLUN provides full control and programmability of NVMe-oF parameters, providing unique storage test conditions for testing and development. 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. Very complex error conditions can be simulated to provide a unique platform for backplane and controller testing. The ability to program complex and varying range of target configurations and save and restore multiple target configurations provides a flexible, cost effective and invaluable tool for development, test & QA labs.
Initiator emulation delivers the ability to drive NVMe-oF traffic, inject errors, send specific or custom op codes in an easy to use, scriptable platform. The ability to affect fabric login parameters is useful in switch and fabric testing and development. 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 NVMe-oF hosts.
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.
