Optimizing Volume Performance for a Transient Cluster

Depending on node size, and on how many EBS volumes are attached, most EC2 nodes will have many independent attached volumes.

Cloud clusters are often transient: when all jobs are finished, the nodes are terminated. Any data held on EBS volumes will remain until next restart, and any data on the local scratch disks disappears forever. When the cluster restarts, each node will have a new ip addresses and identity.
