polyserve and oracle 10g

greetings,

a client is planning on implementing 10g RAC and is looking into hardware and filesystems to use for the implementation. they have settled on linux on ibm servers and are still deciding which cluster file system to use. polyserve is an option, as well as OCFS.

i've seen some references that oracle does not certify oracle products running on polyserve and that the support for "unbreakable linux" is therefore not provided. i believe this is because polyserve requires a custom kernel to run.

does any one have any experience using polyserve with 10g or 9i RAC? is any one familiar with the hardware and kernel requirements to run polyserve? any notes, white papers, advice will be helpful.

thanks in advance,
haroon
