Yes (SR)
Details
XenServer uses the concept of Storage Repositories (disk containers/data stores). These SRs can be shared between hosts or dedicated to particular hosts. Shared storage is pooled between multiple hosts within a defined resource pool. All hosts in a single resource pool must have at least one shared SR in common. NAS, iSCSI (Software initiator and HBA are both supported), SAS, or FC are supported for shared storage.
