Storage definition
Storage can be defined via Storage Pool entries or Storage Entries tied directly to a logical server.
Cross-technology logical servers require their storage to be SAN-based. This approach uses the
normal SAN-boot approach within Virtual Connect and leverages ESX Raw Disk Mapping (RDM)
technology which presents boot and data LUNs directly to the virtual machine.
When defining storage for a portable logical server, you must select SAN Storage Entry. To allow
flexibility and movement between underlying technology types, storage must be presented to the
WWNs tied to the Virtual Connect server profile and storage must also be presented to any ESX
VM Hosts that are potential targets for the logical server. Storage pool entries must be created
within the same portability group associated with the logical server(s) that will use the storage.
