If ESS checksumming doesn’t protect on the wire I’d say that marketing
has run amok, because that has *definitely* been implied in meetings for
which I’ve been present. In fact, when asked if Spectrum Scale provides
checksumming for data in-flight, IBM sales has used it as an ESS up-sell
opportunity.
Noting that on a TCP/IP network anything passing over a TCP connection
is checksummed at the network layer. Consequently any addition
checksumming is basically superfluous.
