Re: [Xen-users] Clustering

[Joseph Glanville <joseph.glanville@xxxxxxxxxxxxxx>]

Hmm these sorts of architectures are possible.
It's worth looking at the work done by the TMEM guys on the xen-devel list.
Technologies exist to mke the latency not such a big deal, for
instance RDMA over Infiniband or SGI's interconnect Numalink.
We are still a few years off having this sort of capability but it is
by no means impossible, just difficult and less efficient than running
multiple machines at this time because of the really complex locking
and sheduling that would need to be in place.

Hope that helps.
Joseph.
