Example 4. In this example diagram Linux MDC Servers are shown, but only MAC Xsan Clients are shown. DS5020 connected to meshed SAN fabric with a single Fibre Channel switch. For DS5020 configurations, Multiple Fibre Channel switches are not required, but they are recommended. Drawing shows minimal SAN to DS5020 connections to simplify the drawing. However, up to 8 connections are supported. In this example, the Meta data Controllers each have a single dual ported HBA. Also in this example multiple HIC cards on the DS5020 are used to increase resiliency.
