5.7 Solution Configurations

The PowerVault™ MD1200 and MD1220 enclosures can be cabled in either a unified-mode
configuration or in a split-mode configuration.
• In a unified-mode configuration the enclosure is connected to one host, for example, a server with a
controller card. The enclosure can be one of up to four enclosures daisy-chained to a single port on the
controller card in the host server. The enclosure can also be connected in a redundant path mode with
two connections to single host server. Redundant path is recommended since it provides cable
redundancy and better performance with automatic I/O load balancing. See Figure 9 and
Figure 10 for cabling diagrams of unified mode configurations.
