Virtualization design questions for newbies
Posted on 2010-11-14
Hello. We are considering virtualization for our production infrastructure. The idea is to create a server cluster (private cloud) that will host all Virtual Machines. I have some design questions and looking for opinions.
- Do we need redundant copies of servers if they are running on a cluster? For instance we now have two web servers on a webfarm in order to provide fault tolerance against server failures. If the VM is running on a server cluster, would you recommend to have redundant copies (ie two web servers) or would just one copy be sufficient?
- Can Windows 2008 R2 be used to create a server cluster? Do we need a special edition (ie Enterprise or Datacenter) or can Standard be used?
- If we are hosting web/application servers (not Database Servers) do we need some special storage solution?
