(Correct me if this has changed, but I don't believe it has).
I prefer making my mogstored nodes 64-bit. Under a default 32-bit system
the pagecache is limited to under 800 megabytes, which limits how many
file objects you can have in cache. With a 64-bit storage node you can
bulk in the memory and get a lot more performance out of it.
It should be fine to mix 32-bit and 64-bit nodes. Nothing I've found so
far could cause issues with this.

Is there a general consensus about building a MogileFS setup and if the
main storage nodes should be 64 bit or not.
I am specifically planning to build a large setup that will initially
have 32 bit clients connecting to the storage setup, however these nodes
will eventually be transitioned to 64 bit nodes. Note sure if this is
an issue using MogileFS. In some distributed FS setups, this is a major
concern.
Thanks in advance for any details.
