I've read through your summary above at least twice now but I'm still
having trouble grokking the details of what you're doing.  Judging by the
lack of other responses, I'm guessing others are similarly stymied.
Perhaps you should back up and read the problem reporting guidelines
found at the link below:

Details are important.  Some pieces of information that may prove useful
include:

   1. Does sshing to the same server (presumably running Cygwin's sshd)
      from that or other Cygwin machine exhibit the same problem?

   2. How big is the directory you're running 'ls -l' on?  Do the results
      change if you instead use just '"ls"'?

   3. Who's the storage appliance's vendor?  Who has permissions to access
      it?  Keep in mind that public key authentication that's configured
      for you by default doesn't allow unfettered access to network shares.
      See <http://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-setuid-overview>
      for a detailed description of the authentication options and
      restrictions.
