It does allow re-exporting. My initial sanity test using a VM as the relay (time cat 821MB-file > /dev/null) shows that the re-exported system is about 70% of direct mount speed, with the iostat measured NFS reads/s peaking at 60%. This clearly warrants further testing. >From my experience with VMWare, it's latency that will kill me -- VMware is all about the IOps and latency and uses relatively little bandwidth, so I'm going to concentrate on reliability and latency. If anyone has an idea of what sharp edges I might encounter trying this out, please let me know so I can add that to my validation tests of the idea. Many NICs is a good idea, also. I have 8 on each 7210, so I can dedicate some to this link.
