Has an analysis of most common storage system been done on how they treat SYNC_NV bit and if any additional tweaking is needed? Would such analysis be publicly available?
I am not aware of any analysis and would love to see it done (i'm sure any vendors who are lurking on this list that support the SYNC_NV would surely want to speak up now).
Due to not every vendor not supporting SYNC_NV, our solution is to first see if SYNC_NV is supported and if not, then provide a config file (as a short term necessity) that you can hardcore certain products to act as if they support SYNC_NV (which we would then not send a flushing of the cache). If the SYNC_NV bit is not supported and the config file is not updated for the device, then we do what we do today.
But if anyone knows for certain if a particular device supports SYNC_NV, please post...
