What is the minimum arrangement of hardware to run a cluster to provide
HA web services including MySQL?
Can it be done using just two machines with no NAS - each acting as a
node with storage mirrored across the two machines and conga able to run
on both?
Can IPMI fencing be used in such a case or is it necessary to have a
power-controller that serialises requests to control the power?
What risks are inherent in such a minimalist arrangement?
Thanks
