Firstly, great detailed description, well done. Secondly - I just want to confirm that I have understood correctly...<br /><br />This setup involves using:<br />- 1 Physical Computer<br />- 2 Virtual Machines (Clustered)<br /><br />I come to a roadblock trying to understand the concept behind iSCSI. I know that a shared volume/s are required for a cluster to work, but for testing purposes in this case, can the shared volume simply be a virtual disk or a physical partition on the same 1 physical computer being used?Enrico Dallihttps://www.blogger.com/profile/11804648934196898058noreply@blogger.comtag:blogger.com,1999:blog-7503353345181123469.post-3040725367947754672011-10-18T07:55:47.609-07:002011-10-18T07:55:47.609-07:00Yes, you are creating a virtual disk that acts as ...Yes, you are creating a virtual disk that acts as the iSCSI target. This can potentially be hosted on a VM or on the host system. There is also a wide range of possibilities regarding where to put the vhd file, including direct atttached storage, flash drives, USB/eSATA/Firewire external drives. Like everything else though, there are good ideas and bad ideas about how to architect this type of solution and it is mainly applicable for a sales/consulting or proof-of-concept environment.Mhttps://www.blogger.com/profile/08374372339551009035noreply@blogger.comtag:blogger.com,1999:blog-7503353345181123469.post-29828522247501413552011-10-18T04:59:01.328-07:002011-10-18T04:59:01.328-07:00Hi, great post.
