Target Emulation
SANBlaze target emulation systems for Fibre Channel and SAS provide a virtual, extremely cost-efficient configurable environment for SAN product development, testing and QA.
The systems reduce the need to deploy large farms of physical “scratch” disks or tapes, providing port density, high performance, non-volatile media at a fraction of the cost of physical disks or tapes.
The ability to add latency, have differing read/write sizes, inject a wide variety of errors and save and restore multiple disk configurations provides a flexible and invaluable tool for development, test and QA labs.
