I believe that AMD64 defaults to 4k pages, which makes it behave as ia32 does for the purposes of client/server interoperability. What you describe is not a problem. 99% of Lustre is endian-clean as well, although we are aware of a few nagging bugs, so running mixed-endian (ie, PPC clients and ia32 servers) is not yet recommended. -Phil
Hello-- Christoph Biardzki wrote:> > I''m curious about interoperability between Lustre on ia32 and ia64 - is > it possible to use an ia32 MDS/OSTs and mixed ia32/ia64 clients?Yes, this is possible. There is one outstanding bug related to ia32/ia64 interoperability, and that is a problem with a large-page (ia64) MDS or OST with small-page (ia32) clients. ia64 supports 4k pages, but it is not a common configuration. What you suggest -- ia32 MDS/OSTs and ia32/ia64 clients -- should not pose a problem. Thanks-- -Phil
