[StarCluster] Using a hi-I/O instance as the master node in a StarCluster Cluster

[Dustin Machi]

I've never messed with them on AWS, but I assume that these get mounted 
wherever the local disks get mounted normally.../mnt.  The hi1.4xlarge 
should have two 1tb volumes mounted 
(http://aws.typepad.com/aws/2012/07/new-high-io-ec2-instance-type-hi14xlarge.html) 
or available to mount (fdisk -l).  The don't think the IOPS provisioning 
will matter much here (for the the read/writes to those volumes anyway), 
though they may impact the performance of the EBS volume itself of 
course.
