Re: [bgl-discuss] to answer my own question

[Susan Coghlan <smc@xxxxxxxxxxx>]

Just to clarify.  

The /etc/hosts file has 64 I/O node addresses (ionode1 ... ionode64,
172.30.1.1-172.30.1.64) listed.  We have 32 I/O nodes. As you guessed, the
code to configure the i/o nodes at powerup skips every other address and
thsu required us to have 64 defined (or else all the i/o nodes in the
upper midplane had the same ip - which was fairly difficult to debug).  
We have 16 storage nodes (i.e. the nodes which will be used to serve PVFS)
also defined fs1 .. fs16.
