As you know there is an email from me reaching out to you on exactly the topic
of tiered storage in your inbox still waiting for a response. I know
conclusively at least Suresh and Sanjay received a copy. I sent that at the
invitation of one of your colleagues last month. Perhaps I can conclude from
the silence that email is an incorrect way to "reach out", in which case I
would welcome your participation on HDFS-4762 in a truly inclusive community
process of collaboration, rather than dubious invitations, based on my personal
experience, here.

> HDFS currently supports configuration where storages are a list of
> directories. Typically each of these directories correspond to a volume with
> its own file system. All these directories are homogeneous and therefore
> identified as a single storage at the namenode. I propose, change to the
> current model where Datanode * is a * storage, to Datanode * is a collection
> * of strorages.
