Personally, I think it may be more important to improve portability of
Ceph at the architecture level. For example, the coming ARM64 support,
ARM has proven its name for its low power etc, it shoule be extremely
suitable for running IO extensive application like Ceph.
Does Inktank or any other party have plan on that? We would be very
interesting in that, and pleasure to contribute.

We did some work on Sparc machine, fixed some little endian/big endian as well

managed to compile Ceph, however, it still could not work properly due to some

Any experiences on running Ceph on big endian machine to share?
We built on a PPC machine a while back and used that to verify that the
big/little endian stuff was working. We don't have any big endian
machines in our lab to let us verify this on an ongoing basis, however.
I'm not sure what the best options are to do that... qemu?
We'd love to see what endian issues you did hit, by the way, to make sure
they make into the tree!

Recently I've managed to get Ceph built and running on OSX. There was
a past effort to get Ceph working on non-Linux platforms, most notably
FreeBSD, but that approach introduced a lot of ad-hoc macros that has
made it difficult to manage changes needed to support additional
platforms.
This session would address the areas within Ceph that are currently
non-portable, discuss the state of OSX support, and touch on what is
needed to factor out platform specific functionality. Changes are
roughly grouped into (1) internal critical (e.g. locking) (2) internal
non-critical (some optimizations), and (2) exported headers. A
significant amount of the OSX changes have been introduced as feature
tests with generic alternatives, and as such the tree may already be
near building on additional platforms, so it would be great to find
people that would be willing to test on additional platforms.
If you are interested please add yourself as an interested party or
owner of this blueprint :)
