ISO C++ lets one decare a static constant in a header:

    static int const MY_FAVORITE_NUMBER (42);

But your variable is not const; the compiler would accept this line:

    IOTable::IOTableIdentifiers[0] = "Z";

Your _first_ 'const' only means the compiler will not permit this
line:

    IOTable::IOTableIdentifiers[0][0] = 'Z';

> static const char* const IdentifierSuffix="_S";

By contrast, 'IdentifierSuffix' is elegible because the pointer
itself is constant.
