What is the difference between remote storage that is shared and non-shared?
Non-shared remote storage (such as an FC Storage Area Network (SAN) or an iSCSI SAN through hardware iSCSI adapters) can be used with our product, but will act like locally attached disk. When virtual machines (VMs) are stored on non-shared remote storage, they cannot be live relocated between systems; they also cannot be automatically placed on other servers when they are started. With non-shared storage, the VMs on that storage can only be seen by one virtualization server. Shared remote storage (such as connections to an iSCSI SAN though our built-in software initiator or our Network File System (NFS) client) allow a VM to be accessed by multiple virtualization servers. This allows for VMs to be XenMotioned between systems. It also allows for automatic placement of virtual machines as they are started.
