Unfortunately, the R905 is EoL, so any updates are not likely.

The thing that concerns me, though, is the delay in I/O for vsphere 
clients.  I know 2 or more retries of 60 seconds caused issues.  I'm 
going to try again with 5 20-second retries, and see how that works.  If 
this doesn't cooperate, I may need to look into an PDU or something...
