Same here; the GUID varies only slightly between large sets (different
production runs, apparently) of C series servers. Globally unique,
indeed :)

An alternative is to construct a guid from the bmc lan port mac
address, obtained with 'ipmitool lan print', for example. Either hash
it with something like md5, or use a 10-byte prefix and tack the mac
address on at the end.
