RDS
I'm struggling to find a clear and definitive description of what RDS needs ito a s/w stack and how to configure it.
It runs over Infiniband. Documentation seem to indicate that IPoIB must be enabled (makes sense as IP addressing and interface are needed).
But what else does RDS run on? Can it run via RDMA (seen mention in some web notes of rds-rdma)? How does this differ from running it via IP (using rds-ip)?
Basically, what is needed in the kernel (specific modules) in order to load RDS for running via IB?
The most detailed document I've found thus far was from IBM - and outdated as it referred to an older OFED version (which was very buggy in my experience) for a much older Linux kernel than RHEL/OL5 (never mind RHEL/OL6).
Reference URLs and comment will be much appreciated.
