IS NVME STORAGE RIGHT FOR TELEMETRY APPLICATIONSGenerally, telemetry applications are not on the cutting edge of storage technology for several reasons: they do not need the high performance, cannot provide the power for high performance, and cannot afford the instability of new technologies. While Non-Volatile Memory Express (NVMe) might initially seem to be the opposite of those goals, it does in fact have the ability to meet them; power and performance can be matched to an application’s needs, and NVMe is gaining stability as it gains overall market share. With the overall data storage industry moving to NVMe, other storage interfaces will begin to decline and future improvements will occur only on NVMe. With the right ruggedization and customization options, NVMe can be a good fit for telemetry applications.
PROPOSED U.2 STORAGE PIN OUT FOR TELEMETRY APPLICATIONSThe Non-Volatile Memory Express (NVMe) storage interface takes advantage of the internal parallel memory architecture found in many Solid-State Drives (SSDs) to provide high performance bandwidth. While relatively new, NVMe is gaining in popularity, but most vendors do not provide the features needed by telemetry applications. Recognizing that the standard does not define these features, several vendors have collaborated on a standard pin out for the 2.5” U.2 form factor that will provide these features such as write protection, data elimination, encryption, security, and authentication. By following this pin out, both system designers and SSD designers can benefit from this compatibility.
