Very interesting Ken, ☺

Just thinking out loud It’d be great to see some kind of SSD integration so it was possible to have multiple tiers of storage as well, The SSD’s would be useful for Gold Virtual machine images / data that needs to be accessed or written to  fast and maybe a replica is set on standard sata disks instead of using zfs’s caching we could use a couple of cheaper ssd’s in each node to act as caches similarly as to how the high end gear aka netapp etc works these days

I agree the metadata server is the likely bottleneck but we are also planning to try and store our data inside a large files (virtual machine images).

I guess I’m not quite sure if the performance in any distributed file system in general is were I expect yet. Even using 10gbe, or 20gbps Infiniband/IPoIB

I found this an interesting read http://forums.gentoo.org/viewtopic-p-6875454.html?sid=d4299cd9365550ac3940a0f8a5beff46
