Yes, the rumor is at least partially true, since at least *some* of the
Sun disks are Sabre IPI disks.  But, most companies, Sun included, reserve
the right to change sources to handle supply/cost/reliability issues.  

Anyway, there is a good reason to use IPI, whatever the source:
The throughput is much faster using IPI on Sun systems, anyway.
Highly recommended for people with disk performance problems.
