Now that VastSky has been reported to be on hiatus atleast, I'dd like to propose GlusterFS as a candidate. It is well tested and actively developed and maintained project. I'm personally really interested in "RDMA version". It should provide really low latencies and since 40Gbit InfiniBand is a bargain compared to 10GbE, there should be more than enough throughput availeable.
This would require IB support on XCP but my thinking is, it would be beneficial in many other ways. For example I would imagine RDMA could be used with live migrates. -Henrik Andersson On 20 April 2011 01:10, Tim Titley <[email protected]> wrote: > Has anyone considered a replacement for the vastsky storage backend now > that the project is officially dead (at least for now)? > > I have been looking at Ceph ( http://ceph.newdream.net/ ).
