To answer some more questions: What sort of workload will your Nova VM's be running? This is largely TBD but we anticipate webapps and other non-batch ways of interacting with and post processing data that has been computed on HPC batch systems. For example a user might host a website that allows users to view pieces of a large data set and do some processing in private cloud or kick off larger jobs on HPC clusters
How many VM's are you running? This work is still in the design / build phase. We have 48 servers slated for the project. At max maybe 500 VMs; again this is a pretty wild estimate. This is a new service we are looking to provide What is your Network interconnect between the Scale Storage cluster and the Nova Compute cluster Each nova node has a dual 10gigE connection to switches that uplink to our core 40 gigE switches were NSD Servers are directly connectly. The information so far has been awesome. Thanks everyone. I am definitely leaning towards option #3 of creating protocol servers. Are there any design/build white papers targetting the virutalization use case?
