Subject Re: [from EMC Isilon] -- pls. review "Why HBase on EMC Isilon" post

Perhaps it'd be useful to have performance benchmarks with an Isilon setup
vs. a non-Isilon setup? I saw a graphic promising 50x better performance
for [ostensibly un-released] "Project Nitro," but don't get any sense of
how much faster things would be for a user today. There's also been a lot
of work in the upcoming Hadoop 3.0 release to support erasure coding and it
might be worthwhile to address this if one of the main selling points of
Isilon is its storage efficiency.
