The following section outlines the XenServer storage model.
XenServer storage model
The XenServer storage model used in conjunction with HP StorageWorks P4000 SANs is shown in
Figure 1.

Brief descriptions of the components of this storage model are provided below.
HP StorageWorks P4000 SAN
A SAN can be defined as an architecture that allows remote storage devices to appear to a server as
though these devices are locally-attached.
In an HP StorageWorks P4000 SAN implementation, data storage is consolidated on a pooled
cluster of storage nodes to enhance availability, resource utilization, and scalability. Volumes are
allocated to XenServer hosts via an Ethernet infrastructure (1 Gb/second or 10 Gb/second) that
utilizes the iSCSI block-based storage protocol.
