Understanding Compaq StorageWorks RAID Array 4000 and Infrastructure Cabling 11 Figure 7 shows a clustered server environment with NSPOF. Figure 7. Redundant controllers in a clustered configuration Since many enterprises' storage components are located across greater distances, the servers are connected through single-mode cabling. Using Infrastructure Cabling Infrastructure cabling (or cable plant) refers to the complete cabling system within a building or buildings. This section discusses of infrastructure cabling and includes a scenario in which an RA4000 uses infrastructure cabling to connect across multiple floors. This example should help answer the questions: • Is the existing infrastructure cabling useable? • Does new infrastructure cabling need to be installed? • If new infrastructure cabling is needed, what type should be installed?
