i am not sure what the exact % is , but multiple GSS customers use their
own racks.
GSS supports a variety of Interconnects and the clients can run a large
number of Linux distros, AIX and Windows that are supported, even in
intermix within one cluster.
we also have quite a number of customers using IBM equipment as the
storage resource, but their own servers for the clients, which is usually
the majority of the nodes in a cluster.

There is a world of difference between a tightly integrated system like
that where every component down to the rack is controlled by a single
vendor, and random JBOD expansion enclosure with random x86 server,
random interconnect and random version of Linux.
Noting of course where I work anything that comes in a vendor specified
rack is a big problem due to the fact we use our own racks with water
cooling.
