40 Cabling Your Blade Cluster Hardware

For high availability, each PowerEdge server enclosure requires direct paths to

the attached storage systems. This configuration ensures that all running

applications are available if one of the PowerEdge server enclosures needs to

be shut down for maintenance.

Figure 2-8 shows two PowerEdge 1855/1955 server enclosures cabled to one

supported Dell/EMC storage system in an iSCSI configuration.

Figure 2-9 shows two PowerEdge M1000e server enclosures cabled to two

supported Dell/EMC storage systems in Fibre Channel configuration.

In both figures, the server module’s dual-port Fibre Channel daughter card

and Fibre Channel modules are connected internally in the system chassis.

You can use a similar configuration model for other supported server modules,

server enclosures, and storage arrays.
