moxspec-ocpsel

An OCP SEL decoder

Why needed / Story behind MoxSpec

1. Operation at scale with Open Compute Project (OCP) / White boxes

When you adopt Open Compute, instead of getting the benefit out of "part level" replacement for a better standardization and operational efficiency, the onsite service team might face to a challenge in the troubleshooting to identify what component needs to be replaced. MoxSpec-OCPSEL is developed and allows SEL (System Event Log) decoded to human readable information, which allows onsite service team easily identify what to be replaced such as a DIMM slot. Democratizing the chance to gain another level of operational scalability to us by adopting open technologies like OCP was crucial and a holistic approach to even a 19” OEM servers was needed.
