Silent data corruption
Introduction
There are certain types of storage errors that go completely
unreported and undetected in
other storage systems which result in corrupt data being provided to
applications with no
warning, logging, error messages or notification of any kind.  Though
the problem is
frequently identified as a silent read failure, the root cause can be
that the write failed,
thus we refer to this class of errors as “silent data corruption.”
These errors are difficult
to detect and diagnose, yet what’s worse is they are actually fairly
common in systems
without an extended data integrity feature.
